in Blog in English

Comments

In recent years, the expansion of photovoltaic systems in Italy has reached unprecedented levels. Between January and June 2024, 3.34 GW of new photovoltaic power were installed, an increase of 145% compared to the same period in 2023. In total, as of June 2024, 1,763,977 photovoltaic systems were in operation for a total power of 33.62 GW. This growth was mainly driven by large-scale (utility-scale) plants, which recorded an increase of 240%. This notable growth reflects the country’s commitment to greater energy sustainability and the adoption of renewable sources.
A key factor in maximizing the efficiency of these systems is energy storage. Storage systems allow you to store excess electricity produced from renewable sources, making it available when needed and increasing the flexibility of the electricity grid. These not only balance supply and demand, but also stabilize the electricity grid, effectively integrating renewable sources.

How Photovoltaic Storage Works

Energy storage is essential to optimizing the use of photovoltaic systems. This system allows you to store excess electricity produced during peak solar hours, to then send it back to the grid or use it when production is low.
The heart of storage systems are batteries, which transform solar energy into chemical energy, and then convert it back into electricity.
The process of storing energy in photovoltaic systems is essential to optimizing the use of solar resources. It starts with solar panels that capture solar energy, converting it into direct current (DC) electricity. This energy is then transferred to a storage system, usually consisting of batteries, which stores it for future use.
The next step is the conversion of the stored energy. Batteries store energy in the form of direct current, but to power most appliances and devices, conversion to alternating current (AC) is necessary. An inverter does this, making the energy usable for home consumption or for being fed into the electricity grid.
Imagine the process as a simplified diagram: solar energy is collected by panels ➔ stored in batteries ➔ converted from DC to AC ➔ used or distributed.
This technology allows you to make the most of solar energy, reducing grid dependency and supporting a transition to a more sustainable energy future.

Types of Batteries for Photovoltaic Systems

When it comes to batteries for solar systems, the main choices include:

Correct management of financial resources is, in fact, another key aspect. Carefully monitoring revenues in relation to the performance of the system is a fundamental activity to ensure the correct valorization of the energy produced.

From this perspective, the automation of the control of electricity sales invoices to market operators and incentives received from the GSE is a central element. This challenge, closely linked to the minimization of errors in remote meter reading, is crucial for the correct monitoring of cash flows.

In particular, the Energy management area of EF Solare Italia uses the R-Cloud section dedicated to monitoring revenues from the GSE Conto Energia agreement. The platform also allows you to effectively manage the billing relating to PPA (Power Purchase Agreement) contracts for the sale of energy produced by photovoltaic systems and Guarantees of Origin. This is possible thanks to the automatic control of the amounts based on the real and estimated load profiles, which Raptech allows you to access quickly and automatically through the TSO, DSO and GSE portals. Finally, R-Cloud allows you to quickly verify the correct application of the contractual conditions for the sale of energy, allowing you to distinguish between fixed-price sales contracts and variable-price market contracts.

“What is Renewable Energy Today”, a book by Gianni Silvestrini

by Redazione

in Blog in English

Comments

The book “What is renewable energy today” (Edizioni Ambiente – 2022) offers a complete and updated overview of renewable energy.

Written by the author Gianni Silvestrini, an expert in the sector, with contributions from David Chiaramonti, Giacomo Talluri, Tommaso Barbetti, Giuseppe Barbera and Giovanni Battista Zorzoli, the book is aimed at young people, activists, schools, associations and businesses, with the aim of providing a comprehensive tool on renewables.

Silvestrini analyses several key aspects, such as storage systems, network management, energy communities, biomass and energy efficiency. The book also highlights why focusing on fossil fuels or nuclear is not only risky, but also less economically advantageous than reducing consumption and using renewable energy. The volume provides a comprehensive and updated overview of the contribution of renewable energy to the decarbonisation of the economy and job creation.

Furthermore, it analyses the strategic role of renewables in the new international scenario, seriously compromised by the war in Ukraine, which according to the author will have more significant consequences than the Gulf crises.

The Italian situation

About ten years ago, Italy saw a strong growth in renewable energy thanks to generous but often poorly coordinated incentives. Subsequently, governments seemed to want to punish the sector, as if they had already given too much to renewables. However, this decision was not appropriate, as module prices have fallen dramatically, making it convenient for the system to focus on clean energy. Despite the increase in module prices due to the international situation, global investment in renewables continues to grow. No other technology, including nuclear, can compete with this trend. The Italian goal of reaching 72% of electricity from renewable sources by 2030 is very ambitious, but renewables are now an unstoppable train.

The motivations behind the book

Considering the current energy situation, the motivations behind this book are even more relevant. It is often asked whether the war will lead to a slowdown or an acceleration of renewable energy. In the short term, there could be a brake (such as the reopening of coal-fired power plants), but from a strategic point of view the opposite happens: Germany had set a target of 80% renewables by 2030, now, driven by the desire to reduce dependence on Russian gas, it aims for 100% by 2035. Unlike Germany, Italy has no coal reserves and imports all the gas it uses, covering over 40% of its electricity needs. Consequently, our commitment to renewables should be even stronger.

Huge potential from photovoltaics and wind

The transition to clean energy must accelerate significantly, with solar and wind as the main protagonists, together with biomass. Photovoltaics in particular has huge potential, thanks to innovative solutions such as seasonal storage and industrial use to produce heat. China remains the global leader in photovoltaic power generation, but the United States and especially Europe are expected to recover significant market shares in the next decade. However, this growth requires overcoming some challenges, such as the shortage and high prices of silicon, the insufficient use of agricultural land for solar panels, and the limited production of photovoltaic modules in Europe.

Agrivoltaics and offshore wind

Agrivoltaics and offshore wind have great potential, although they still require experimentation. Research into agrivoltaics has shown that the shading of panels can have a very positive effect on some crops, such as vines in France. With rising temperatures, agrivoltaics can be very effective in Italy and other countries. Offshore wind has already been successful in the North Sea, with costs per kWh much lower than the new nuclear power plant under construction in England. Offshore wind is also expected to play a major role in the Mediterranean over the next decade, despite the weaker winds.

Energy Communities

Another important innovation is renewable energy communities. First, renewable energy communities (CERs) promote a cultural change, increasing the level of information and understanding of citizens. So far, active CERs are small in size, created from the bottom up and with a strong social impact. Although there is a risk of limited management capacity, the opportunity lies in the involvement of businesses, which could provide capital and technical expertise to create larger and more stable energy communities. The synergy between businesses and citizens has great potential and could lead to the inclusion of entire neighborhoods or municipalities.

A path not without obstacles

Silvestrini explains that the role of renewable energy will be central in the fight against climate change, but it will not be a simple path without obstacles. Rather, it will be an obstacle course that will require intelligently addressing issues such as the landscape, regulatory and authorization aspects, as well as the difficulties of supplying critical materials. Furthermore, the profound transformation of the global energy sector will still lead to resistance from fossil fuel sectors that feel threatened. However, this path can also become an opportunity to involve local realities, arouse emotions, prefigure alternative futures and push the search for new solutions.

Artificial Intelligence in Renewables: Between Hype and Reality

by Redazione

in Blog in English

Comments

In recent years, the buzz around artificial intelligence (AI) has reached fever pitch, affecting industries from healthcare to finance. However, as we navigate this landscape, especially in the realm of renewable energy, it is critical to discern the line between the hype of AI and its tangible benefits. With the growing urgency of climate change, AI’s potential to support human labor in renewable energy promises not just innovation, but real solutions for a sustainable future.

The Landscape of Artificial Intelligence in Renewable Energy

Artificial intelligence (AI) encompasses a broad range of technologies designed to enable machines to mimic human cognitive processes. In the renewable energy sector, AI offers advanced solutions to optimize energy production, manage demand response and improve predictive maintenance of plants. Companies are increasingly adopting these technologies to streamline operations, reduce costs and facilitate decision-making, leveraging AI’s ability to analyze massive amounts of data and provide fast, accurate results. However, while progress in the sector is promising, practical implementation and scalability of these technologies remain a challenge.

For example, AI algorithms can process large amounts of data from wind turbines and solar panels to more accurately predict energy production. This accurate forecasting facilitates better integration of renewables into existing energy networks, helping to reduce disruptions and maximize operational efficiency. With these capabilities, AI is supporting the transition to a more flexible and sustainable energy system. Another key aspect is the role of AI in dynamically managing energy demand. Using real-time data, algorithms can adapt energy usage and distribution in response to fluctuations in demand, ensuring greater stability of the power grid.

This approach not only ensures a constant supply of renewable energy, but also reduces stress on the overall energy system, helping to create a more resilient and secure energy infrastructure. In addition to optimizing energy production and distribution, AI is revolutionizing predictive maintenance of renewable assets. By analyzing operational data and identifying patterns, AI algorithms can predict impending failures or maintenance needs before major problems arise. This proactive approach minimizes plant downtime, maximizes asset utilization, and extends the useful life of wind and solar plants, thereby improving overall efficiency.

The dichotomy between hype and reality

Despite the great theoretical potential of artificial intelligence (AI), its practical implementation is lagging behind for several reasons, including technical, economic, social and regulatory issues. Some of the main challenges include:

Infrastructure complexity: Integrating AI requires advanced and up-to-date technological infrastructure. Many energy networks, for example, were designed before AI and renewable energy became central to global energy strategy. Upgrading these networks and installing the sensors, software and hardware needed for AI is expensive and requires a long implementation time.
Data availability and quality: AI relies on large amounts of data to function effectively. However, in renewable energy, the data collected can be incomplete, disorganized or of variable quality. Collecting accurate data from renewable energy sources, such as wind turbines or solar panels, can be challenging, especially in remote environments. Without reliable data, AI algorithms cannot reach their full potential.
Upfront costs and investments: While AI can generate long-term savings, initial implementation requires significant investments. This includes development costs, infrastructure, hardware, training, and customization of systems. Companies, especially smaller ones, may struggle to justify these upfront investments, preferring more traditional and less expensive solutions.
Training and specialized skills: Effective use of AI requires highly skilled engineers who understand both renewable technologies and the complexities of AI. There is a significant gap between the speed at which AI is advancing and the training of the workforce needed to operate and maintain these systems. A lack of specialized skills is holding back widespread adoption of AI.
Mistrust and resistance to change: Many organizations and operators may be skeptical about adopting AI, especially due to fears of losing control over critical systems or uncertainty about the outcomes. This cultural and psychological resistance can slow the diffusion of new technologies, even when they demonstrate potential for improvement.
Regulation and governance: AI implementation is governed by regulations that often fail to keep pace with technological evolution. Integrating AI into regulated industries such as energy requires clear guidelines on safety, ethics and transparency. Lack of adequate regulation can create uncertainty, making companies reluctant to adopt AI at scale.
Scalability and customization: AI algorithms developed in the lab or for specific applications may not work as well in larger or different contexts. Often, an AI system that works well in a small-scale situation must be redesigned or adapted for implementation at an industrial scale. Customization of AI solutions can be expensive and complicated.
Interoperability: In energy systems, AI must integrate with existing technologies that may not be compatible. Interoperability between new AI systems and existing infrastructure and software is a significant challenge. Technologies need to “talk” to each other, and this often requires implementing standards or updates that can slow down the process.

In summary, while AI has enormous potential to transform the renewable energy sector, its impact is hampered by infrastructural, economic, regulatory and cultural obstacles. Addressing these issues requires strategic investment, more flexible regulation and a shift in mindset among both industry players and policymakers.

Real-world applications of AI

Despite skepticism, there are notable cases where AI is having a measurable impact in the environmental protection sector. Companies like Google have integrated AI into their data centers to reduce energy consumption. Using machine learning algorithms that analyze data in real time, Google has reportedly reduced its energy consumption for cooling systems by 30%.

Another application is waste management. AI systems are used to optimize waste collection and disposal processes, reducing environmental impact and improving recycling. Thanks to advanced recognition capabilities, AI can identify recyclable materials and separate waste more efficiently than traditional methods. Finally, AI is being used in monitoring air and water quality, collecting and analyzing large amounts of data in real time to identify pollutants and develop mitigation strategies. These tools allow for rapid response to environmental emergencies, such as oil spills or forest fires, helping to minimize damage.

The Future: Balancing Hype and Pragmatism

As we move deeper into the renewable energy era, it is critical to shift our focus from mere excitement about the potential of artificial intelligence (AI) to its concrete, pragmatic application. AI, while innovative and promising, requires a thoughtful strategy that balances technological euphoria with the real needs and challenges of the energy sector. It is important to understand that the successful implementation of these technologies is not just about their sophistication, but also about how to put them into practical, operational contexts. A key aspect of this transition is investing in education and training.

Creating educational programs aimed at renewable energy engineers and professionals could address the skills gap that often holds back AI adoption at scale. By equipping workers with a solid understanding of AI technologies, they can be made more accessible and effectively integrated into everyday applications, thereby reducing resistance to change and increasing operational efficiency.

In addition to training, it is essential to develop tools and platforms that promote technological innovation, but at the same time mitigate its risks. Creating collaborative environments where businesses, AI developers and policy makers can interact, share knowledge and test solutions would foster a safer and more thoughtful adoption of new technologies.

These tools could include simulators, small-scale test environments and pilot projects that allow us to anticipate potential critical issues and optimise the integration of AI technologies into renewable energy production processes. Successfully addressing the future of renewable energy therefore requires a vision that combines enthusiasm for new discoveries with a practical and realistic approach. The allure of innovations must be accompanied by careful planning that takes into account infrastructure needs, human resources and implementation times. Only in this way can we avoid the pitfalls of too rapid or poorly orchestrated adoption.

Key differences between Revamping and Repowering of a Photovoltaic System

by Redazione

in Blog in English

Comments

Photovoltaic energy has been with us for a long time and over the years the systems lose their efficiency and generate a lower yield. As photovoltaic systems age, the concepts of revamping and repowering systems become increasingly relevant for both producers and operators. However, the real market size for new photovoltaic components in existing systems depends on the characteristics of each system, the general regulatory framework and the economic benefits.

These terms might seem complicated, but they actually represent two fundamental strategies for improving the efficiency and productivity of the solar system.

Revamping of photovoltaic systems

Revamping is the process of renewing or modernizing an existing photovoltaic system, in order to restore its full effectiveness and energy efficiency without replacing the entire system. Reference is made to all procedures aimed at modernising, modifying and improving an old photovoltaic system.

Over time, photovoltaic components can lose their effectiveness, so replacing them can improve overall performance.

The goal of revamping is to increase power output and improve system reliability, which can result in lower operating costs and a better return on investment.

The revamping process involves an evaluation of the existing system, upgrading components such as inverters, modules and finally testing and commissioning. With this method, you can achieve increases that will make your system more efficient and reliable.

Repowering of photovoltaic systems

Unlike revamping, repowering involves a deeper transformation of the system and involves a series of operations aimed at increasing the power of the system through the replacement of old components with more performing ones or the addition of new elements. Repowering can allow for greater energy production, increasing installed power and making the system more competitive in the long term. With newer, more reliable components, your system will be less prone to failures and interruptions.

As regulations and technologies evolve, repowering can help ensure your facility complies with current regulations.

The repowering process involves an evaluation of the system’s current performance and the replacement or addition of new components. While it may require a larger investment than revamping, repowering can bring significant long-term benefits.

Advantages of Revamping a Photovoltaic System

The revamping of a photovoltaic system offers a series of benefits that cannot be ignored. First, it allows for a significant increase in system efficiency. This means that the plant will be able to produce more energy with the same amount of sunlight, thus reducing operating costs and increasing profits. Additionally, revamping can lead to reduced maintenance costs, as upgraded components are often more reliable and require fewer repairs.

Here are some of the main advantages of revamping:

Increased energy efficiency
Reduction of maintenance costs
Extension of the life of the system
Improved plant safety

An interesting case study concerns a plant located in Puglia, where revamping led to a 30% reduction in annual maintenance costs. This was possible thanks to the installation of new inverters and more efficient solar panels. The revamping improved the safety of the plant, reducing the risk of faults and fires thanks to the use of more modern and safe components.

Benefits of Repowering for Your Photovoltaic System

Repowering the photovoltaic system can lead to a significant increase in production thanks to greater installed power. Imagine being able to make the most of the space available to you, improving the efficiency of your system.

Repowering also contributes to environmental sustainability. By replacing old components with more advanced technologies, you reduce the environmental impact and extend the useful life of your system. Even in this case let’s not forget the long-term economic benefits: a more efficient system means fewer operating costs and greater savings on the energy bill. Ultimately, repowering is a smart choice for those who want to maximize their investment and contribute to a greener future.

Revamping Process: Steps and Considerations

The revamping of a photovoltaic system is a crucial process for improving the efficiency and productivity of the system. Here is a detailed guide on the basic steps:

Initial assessment of the facility: First of all, it is essential to perform a comprehensive assessment of the existing facility. This includes analyzing current performance, identifying obsolete components and evaluating the overall condition of the system.
Replacement of obsolete components: Once the evaluation is completed, the components that no longer function optimally are replaced. This can include solar panels, inverters and other electronic devices.
Updating the management software: Another fundamental step is updating the system management software. This allows for improved monitoring and control of the system, ensuring greater operational efficiency.
Post-revamping testing and monitoring: After completing replacements and upgrades, it is crucial to perform thorough testing to ensure everything is working properly. Continuous post-revamping monitoring helps identify any issues and further optimize plant performance.

Revamping is not just a matter of replacing old components, but an opportunity to significantly improve the efficiency and longevity of your photovoltaic system.

Repowering Process: Steps and Considerations

Repowering a photovoltaic system is a complex process that requires careful planning and a series of well-defined steps.

First of all, it is essential to perform an analysis of the potential for increasing capacity. This involves evaluating the space available, whether the existing system can support an increase in power and what the structural and technical limits to consider are.

Once the analysis is completed, the panels are replaced with more efficient models. New generation photovoltaic panels offer greater energy efficiency, allowing you to generate more energy with the same surface area. This is a crucial step to maximize the performance of the system. In addition to the panels, you need to upgrade the inverters and other critical components. Modern inverters are more efficient and reliable, helping to improve overall system performance.

After installing new components, it is essential to perform post-repower testing and monitoring to ensure that everything is working properly and that the system is operating at maximum capacity.

In summary, repowering a photovoltaic system requires a series of well-coordinated steps, from initial analysis to component replacement and final monitoring. Each step is crucial to ensure a significant increase in the plant’s production capacity.

Key differences between Revamping and Repowering

The concepts of revamping and repowering are closely connected to each other, to the point that you may struggle to understand what difference there is between the two. They are both practices united by the fact that they aim to improve the efficiency and prolong the life of pre-existing photovoltaic systems.

Revamping focuses on updating existing components, while repowering involves an increase in installed power while optimizing the use of space.

Revamping is generally more cost-effective, repowering may require a larger investment. However, it can bring a much greater long-term benefit.

When to Choose Revamping over Repowering

Deciding between revamping and repowering a photovoltaic system may seem complicated, but there are some key criteria that can help you make the right choice. First of all, consider the age of the plant. If your system is more than 10-15 years old, it may be time to think about repowering, which involves replacing major components such as solar panels and inverters to improve overall efficiency. On the contrary, if the system is relatively new but has performance problems, revamping, which involves the maintenance and updating of specific components, could be the ideal solution.

Another crucial factor is the available budget. Repowering tends to be more expensive than revamping, but offers long-term benefits such as increased energy production and extended plant life. If your budget is limited, revamping can still offer significant improvements without requiring a massive investment.

Analyze your current and future energy needs. If you expect an increase in energy consumption, repowering may be the best choice to meet these new needs. For example, a company planning to expand its operations might opt for repowering to ensure adequate energy supply. On the other hand, if energy needs remain stable, revamping may be sufficient to keep the plant in optimal condition.

Another difference concerns the regulatory aspect. While revamping follows the guidelines of the Energy Services Manager (GSE) and can include significant and non-significant interventions, repowering is often incentivized through financial support programs that reward operators who increase the capacity of their plants.

In summary, the choice between revamping and repowering depends on a combination of factors such as the age of the system, the available budget, the energy needs and the available incentives. By carefully evaluating these aspects, you can make an informed decision that maximizes the efficiency and longevity of your solar system.

Whether you choose to revitalize your photovoltaic system with revamping or transform it more profoundly with repowering, it is essential to adopt an approach that ensures greater efficiency and sustainability in the long term. Investing in the regeneration of photovoltaic systems is a smart choice to reduce environmental impact and maximize the production of clean energy.

by Redazione

in Blog in English

Comments

The growing attention towards climate change and the depletion of fossil resources is leading the world towards a new era, in which digitalisation plays a fundamental role.

But what exactly does this energy transition mean and how can digitalisation help companies overcome the challenges and exploit the opportunities it offers?

The energy transition is a process that aims to reduce the use of non-renewable energy sources and promote the adoption of renewable sources, such as solar, wind and hydroelectric energy. This is essential to reduce greenhouse gas emissions and limit climate change.

Furthermore, the energy transition is also a response to the increasing depletion of fossil resources, which are limited and unsustainable in the long term. This new energy model represents a great challenge, but at the same time offers opportunities for development and innovation for companies.

In this blog post we will examine the relationship between digitalisation and energy transition, highlighting how the synergy between these two areas is redefining the global energy landscape.

The digital transformation of the energy system represents a significant factor that profoundly changes the process of energy production, distribution, storage and management.

This digital revolution is present in several ways:

Smart Grid: traditional electricity networks are transforming into intelligent networks that use sensors, control devices and data analysis to optimize energy distribution. Smart Grids allow for a more flexible and decentralized network, allowing better management of supply and demand, reducing waste and improving overall efficiency.

Projections suggest that approximately 17% of investments in networks will be oriented towards innovations regarding the transmission (TSO, Transmission System Operator) and above all the distribution (DSO, Distribution System Operator) of renewable sources.

Data monitoring and analysis: The process of digitalization of the energy system can be significantly supported by the use of data. The data can help identify areas for improvement in energy production, providing important insights into system performance and inefficiencies. This data can be used to optimize manufacturing processes, reduce costs and increase energy efficiency.

Distributed energy: this form of energy production has numerous advantages, including greater security and resilience of the energy system, a reduction in greenhouse gas emissions and greater autonomy and independence of local communities. Furthermore, thanks to digitalisation, it is possible to manage decentralized energy production more efficiently and intelligently, optimizing the use of renewable sources and reducing waste.

Thanks to the initiatives of the European Commission, the renewables sector is becoming increasingly efficient and sustainable thanks to the use of IoT devices, smart meters and 5G and 6G connectivity networks. It is important to continue investing in and supporting the development of these technologies to ensure an effective and inclusive transition to renewables for all. Collaboration between digital and renewable technologies is essential to achieve the objectives of reducing emissions and protecting the environment.

The digitalization of the energy system requires open and interconnected digital solutions, together with data quality assurance. Among the main fundamental elements:

Precise monitoring and control: Digitalisation is revolutionizing the way we monitor renewable sources such as solar and wind energy. Thanks to advanced technologies and systems, we are able to collect and analyze more precise and timely data on the performance of these energy sources. This allows us to make informed decisions to optimize the production and use of renewable energy.
Demand management: digitalisation allows for more flexible and efficient management of energy demand, ensuring better use of available renewable resources. This translates into greater reliability of the energy system and reduced costs for consumers.
Energy efficiency: Digital technologies help optimize energy efficiency in systems, reducing waste and overall costs.
Technological innovation: Digitalisation promotes the innovative evolution of the energy sector, promoting the development of new technologies and more efficient and sustainable solutions.

In summary, digitalization plays a crucial role as a catalyst in the energy transition. The integration of digital technologies into energy infrastructure contributes not only to reducing environmental impact, but also to increasing efficiency, resilience and innovation in the energy sector globally.

The Stern / Raptech case study: Operations & Maintenance

An example of the importance of the digital and energy transition combination is represented by the collaboration between Stern Energy, a specialized operator that offers technical services of O&M, Asset Management, revamping and construction of photovoltaic systems on European territory, and Raptech, specialized in digital monitoring systems and asset management.

The main challenges posed to Stern in the Operations & Maintenance area concerned the reduction of plant downtime, the maximization of production and the search for high performance in the plant and monitoring systems.

From a technical perspective, managing a photovoltaic system can present some significant challenges. It is important to understand these challenges to ensure proper operation and maximize energy production.

Photovoltaic systems, especially large ones, require continuous maintenance and monitoring due to their complexity and large number of components. Constant monitoring and timely interventions are essential to prevent failures or malfunctions, which could compromise the efficiency of the entire system.

Optimizing the energy produced is further complicated by external factors such as climatic conditions and the availability of sunlight. These elements make a dynamic approach to planning and monitoring necessary, in order to optimize energy production and minimize waste.

An effective monitoring system is therefore essential to guarantee the efficiency and productivity of a photovoltaic system. This system must be able to collect accurate data and provide tools for their in-depth interpretation and analysis. Only through accurate data management is it possible to obtain valuable information for the continuous improvement of operations, the prediction of any problems and the adoption of proactive solutions.

Thanks to the functions that Raptech provides to Stern Energy through the tools they have developed, it is possible to use practical and strategically relevant functions in the management of photovoltaic power plants, such as:

Call Intra Day: when a plant for one reason or another stops communicating or in any case being reachable by the main monitoring system, the use of the Call IntraDay helps Stern Energy to evaluate the operation of the plant by bypassing the monitoring system, ensuring that the plant is regularly in production;
Pods Monthly productions: for the preparation of monthly reports for customers, it is possible to detect the energy input data of the relevant POD (system). This function allows you to save a lot of time when drafting the report as it is no longer necessary to access the E-Distribuzione portal on the profiles of the various SPVs to acquire the data;
Meter registers: for the preparation of monthly reports, the production meter registers are recorded directly by Raptech systems;
Repository: it is possible to access the Raptech “archive” relating to the account, specifically you can find the quarterly and daily curves of all the systems (of all the system meters) present in that account. This function allows Stern Energy to always have the curves available in case of need (see requests for E-Distribuzione checks or requests from customers);
Meter status: this function allows you to check remote reading problems for each production meter. Through daily monitoring, Stern Energy is able to intervene promptly on the systems and resolve any problems that could hinder the network manager from correctly remote reading the meters. An alarm is created when a meter is not remotely read by Raptech for five consecutive days;
Monthly Productions: to see, if necessary, the totalizers in terms of energy for each meter, whether GSE or Fedin (also exportable here) for counter-checks and data validation

The Stern / Raptech case study: Asset management

Asset Management consists of the control and optimization of all aspects of the photovoltaic system (Commercial, Technical and Financial). This includes the technical supervision and maintenance activities of the plant, the management of the administrative obligations required by law, the monitoring and management of incentives and the sale of the energy injected (including Certificates of Guarantee of Origin), the management and the payment of operating expenses, and finally, budgeting and financial analysis activities.

The main objective is to maximize profits, optimize the economic-financial situation and maintain an efficient relationship with all stakeholders involved in the project.

Relying on an Asset Management company like Stern Energy offers numerous advantages. First, you get greater operational efficiency, precise revenue control and a significant reduction in operating costs. Careful management of all aspects of the system allows you to obtain the maximum return on your investment and maximize economic returns.

Through data and performance analysis, Asset Management can identify interventions to optimize energy production. This includes strategic maintenance planning, optimization of technical performance and management of purchases and supplies targeted to the needs of the specific plant.

The implementation of an efficient Asset Management system can lead to a significant reduction in plant management costs, improve energy productivity and maximize revenues from incentives and energy sales. Careful monitoring and proactive management are key to ensuring the long-term success of PV investments.

On the Asset Management front, Stern’s main challenges were multiple and mainly concerned the optimization of processes in the administrative and financial management of the plants:

– the minimization of remote meter reading errors: market needs and the economic and financial relevance of the problem in the eyes of investors required an increase in reactivity in identifying deviations and intervening promptly through reports to network managers and the authorities sector, bringing very high economic-financial results to our customers.

Thanks to the help of Raptech, the Stern Energy Asset Management team is able to promptly identify any problems with remote reading and disconnection of the meters and intervene promptly, with the help of the O&M department, to restore them, avoiding misalignments with the distributor in advance network which negatively affect the financial flows of the project.
