The world added 510GW of new solar PV capacity in 2025, the most of any electricity generation source, as global cumulative renewable energy capacity now exceeds 5,000GW.   This is the key takeaway from ‘Renewable Capacity Statistics 2026’, the latest in a series of annual reports from the International Renewable Energy Agency (IRENA). Of the 5,149GW of renewable energy capacity in operation as of the end of 2025, solar accounted for 2,391GW, the most of any energy source and almost double the 1,291GW of wind capacity in operation.   Renewable energy, more broadly, was the driving force behind new electricity generation capacity in 2025, accounting for 85.6% of all new energy capacity additions. Solar, and solar PV in particular, were key contributors to this change.   The IRENA report notes that solar PV accounted for 510GW of the 511GW of solar added in 2025. The other 1GW was concentrated solar. Solar as a whole accounted for 75% of the 692GW of new renewable energy capacity additions made last year.   “This impressive, consistent growth reflects the strength of the economic case for the energy transition; the competitiveness and resilience of renewable power have pushed additions to new records almost every year since the turn of the millennium,” wrote IRENA director-general Francesco La Camera in his foreword to the report.   However, he noted that “significant disparities” remain in deployment, highlighting that China, the US and the EU accounted for 79.5% of new renewable energy capacity installed in 2025. Considering the scale of solar capacity already in operation in these regions—as illustrated in the graph below, where China alone accounted for half of the world’s operational solar capacity at the end of 2025—the world’s solar deployments are becoming increasingly concentrated in a few parts of the globe.   There is encouraging growth in some parts of the world, however, and IRENA draws attention to the Middle East, in particular, as an example of a region with significant growth in renewable energy capacity. The region’s renewable additions increased by 28.9% year-on-year in 2025, with more than 12GW of new solar capacity installations between 2024 and 2025.   This is the most new solar capacity that has ever been added in the region in a year, and means that the operational solar capacity in the Middle East has increased by almost 24 times since 2016.   Saudi Arabia, in particular, has been a driver of this change, boasting 11.9GW of cumulative operational solar capacity, and having added more than 5GW in 2024. Earlier this year, Egyptian firm Elsewedy Electric commissioned a 349MW solar PV project in the country, and the Saudi Arabian solar sector has benefitted from agreements with overseas players, including US tracker manufacturer GameChange Solar and the Turkish government.

On March 4, 2026, the European Commission officially released the draft of the Industrial Acceleration Act in Brussels. This move aims to promote the decarbonization of European industry, enhance the overall competitiveness of EU industries, and facilitate the "Made in Europe" rollout of key products such as photovoltaic modules. This proposed legislation has been submitted to the European Parliament, the Council of the European Union, and other common legislative bodies of the EU, and is now in the negotiation and refinement stage.   The European Photovoltaic Industry Association (EPIA) immediately issued a statement emphasizing the significance of the draft bill. EIA's Deputy CEO, Dries Acke, called the Industrial Acceleration Act a "watershed moment in the development of European industrial policy," noting that the act will, for the first time, grant EU member states the right to prioritize the use of EU-made photovoltaic and energy storage systems in certain public tenders, government procurement processes, and industry support programs.   For decades, EU industrial policy has been primarily formulated by member states themselves, with the EU's main function being defensive: controlling through state aid and antitrust enforcement to ensure that member states' measures do not distort competition. The Industrial Acceleration Act will mark a decisive shift. Originally named the "Industrial Decarbonization Acceleration Act," the bill was renamed in 2025 and expanded its scope, now forming a core pillar of the EU's Clean Industry Agreement's industrial framework.   Dries Acke stated that the bill focuses on EU-made photovoltaic inverters and cells, promoting the return of core photovoltaic components to the EU while avoiding overly stringent entry requirements in the initial stages of policy implementation. This approach effectively supports the development of European manufacturers without hindering the large-scale adoption of grid-parity photovoltaic energy. However, he emphasized that the definition of "Made in Europe" must be strictly limited to products manufactured within the EU and the European Economic Area.   Meanwhile, Dries Acke expressed concerns about the bill's provisions regarding battery storage systems. He pointed out that the draft's requirements are not only more stringent but also take effect too early, potentially hindering the urgent expansion of battery storage systems. Battery storage is crucial for improving the utilization rate of renewable electricity in Europe and reducing reliance on expensive fossil fuel imports, while accelerating the development of the energy storage industry is a necessary measure for the EU to achieve its two core objectives: energy security and industrial competitiveness.   Dries Acke also emphasized the importance of simplifying the legislation, stating that only by streamlining the provisions can the legislation be effectively and uniformly implemented across EU member ...

New data from Raptor Maps, a US-based solar asset analytics firm, shows that despite a maturing market and technological advancements, power losses in solar photovoltaic (PV) projects have more than doubled in the past five years.   According to Raptor Maps' newly released Global Solar Report, the "device-driven power loss rate" for PV projects of all sizes is projected to reach 5.08% in 2025, more than double the 2.36% in 2021.   The report states, "The average power loss rate for solar assets is expected to decline, not rise, as technologies mature, such as solar panels becoming more efficient than ever before." The company identified three main factors contributing to the increase in power losses: the mechanical complexity of projects, labor supply, and manufacturing quality.   The last factor has become a focal point of discussion in industry media and among industry professionals. In January of this year, Kiwa PI Berlin found a "significant and worrying increase" in PV module defects, with over 3.36% of modules having problems before leaving the factory. This is primarily attributed to the emergence of numerous new manufacturing plants in new regions in response to changes in supply chain policies (especially those related to the US).   Raptor Maps states that the increasing mechanical complexity of photovoltaic (PV) projects has led to a corresponding increase in the likelihood of failures. The company highlights the shift from fixed-tilt mounts to active tracking systems. The report states, "While tracking mounts increase power generation, they also introduce more points of failure, including components such as motors, sensors, and controllers, all of which require continuous calibration and maintenance." The report also notes that labor shortages have outpaced the expansion of PV capacity, resulting in widespread staffing difficulties for operation and maintenance companies. The report states that in 2025, the average PV capacity handled by a technician will have increased by 70% compared to five years prior. Raptor Maps notes in the report, "Over the past five years, employment in the U.S. solar industry has grown by 12%, while installed capacity has increased by 286%." In its analysis of the U.S. market, the report indicates that these performance issues exist in PV projects of all sizes across various regions of the United States.   Equipment Issues: In 2025, the mechanical and equipment issues affecting PV power generation performance have changed. Raptor Maps points out that although inverters "have historically been the leading cause of DC-side capacity loss," power losses due to inverter failures decreased by approximately 40% year-on-year last year, accounting for less than a quarter of equipment-related power losses.   In contrast, string and combiner box failures increased by 12.5% ​​and 10.2% year-on-year, respectively, accounting for 26.89% and 21.51% of observed total power losses.   The mos...

I. Why Microgrids Have Been Pushed to the Forefront Microgrids are not a new concept. As early as July 2015, the National Energy Administration issued the "Guiding Opinions on Promoting the Construction of New Energy Microgrid Demonstration Projects," marking the official entry of this field into the demonstration and exploration phase.   In the following years, although some sporadic projects were implemented, overall progress was lukewarm. Only recently, with the intensive release of relevant policies, has the development pace of microgrids become clearly apparent.   To understand its role in the new energy system, let's first return to the concept itself: What is a microgrid?   Simply put, a microgrid is a small, complete power system. It consists of distributed power sources, loads, energy storage devices, power distribution facilities, and a control system, capable of self-control, protection, and management. In other words, it possesses all the functions of power generation, distribution, and consumption, and can achieve optimized energy dispatch within the grid.   Why are microgrids becoming the focus of the market? We must first discuss the current challenges facing the power grid.   A set of data from 2025 succinctly illustrates the problem: my country's installed capacity of new energy sources is approaching 50%, but their share of electricity generation is less than 25%. This huge gap between installed capacity and generation exposes the grid's inability to keep pace with the expansion of new energy.   Specifically, in 2025, the national installed capacity of wind and solar new energy is projected to reach 370 million kilowatts. However, at the same time, more than 150 regions across the country are already struggling to connect new distributed photovoltaic projects due to saturated distribution network capacity. On one hand, installed capacity continues to climb; on the other hand, access channels are blocked. Grid connection difficulties have become a real bottleneck restricting the development of new energy.   Even with successful grid connection, the cost of system integration of new energy is rising. Xie Kai, general manager of the Beijing Power Exchange Center, once calculated that for every 1% increase in new energy penetration, the system integration cost will increase by approximately 1 cent per kilowatt-hour.   According to the State Grid's "Service for New Energy Development Report 2025," the proportion of new energy power generation within its operating area has reached 24.2%. Based on this calculation, the system cost allocated to each kilowatt-hour of new energy currently approaches 0.3 yuan.   What does this mean? If the power grid architecture is not adjusted in time, with the 2035 target of 3.6 billion kilowatts of wind and solar installed capacity approaching, new energy sources will be trapped in a vicious cycle of "scale growth, difficulty in absorption, and high costs." ...

According to foreign media outlet InsideEVs, Nissan recently unveiled a unique Ariya concept car. The car's biggest highlight is its collaboration with Dutch company Lightyear, which covers approximately 3.8 square meters of solar panels on the hood, roof, and tailgate. Under sufficient sunlight, this system can add up to 14.3 miles (about 23 kilometers) of range per day.   While this solar-powered concept car visually demonstrates the potential of using solar energy to alleviate range anxiety, given Lightyear's bankruptcy and the widespread production difficulties faced by competitors, Nissan has explicitly stated that there are currently no plans for mass production of this car.   Nissan's attempt seems more like a technological trial, aiming to verify whether onboard photovoltaic technology is an effective solution for alleviating range anxiety.   Geographic Location Determines the Upper Limit: Range Increase of Only Three Kilometers Although the concept of "using solar energy for charging" is quite attractive, real-world test data for the Nissan Ariya clearly demonstrates the limitations of this technology, which is heavily reliant on weather conditions.   Test results show that geographical location and weather have a significant impact on the Ariya's charging efficiency. In sunny Dubai, the Ariya can travel an extra 13.2 miles (approximately 21.2 kilometers) per day using solar power; however, in cloudy London, the increase is only 6.3 miles (approximately 10.2 kilometers) per day.   To test the vehicle's performance under these conditions, Nissan conducted a two-hour, 50-mile (approximately 80-kilometer) test on a sunny day. The results showed that the solar system only replenished the battery by 0.5 kWh—equivalent to an increase of less than 2 miles (approximately 3 kilometers) in range after this trip.   For electric vehicles with ranges often exceeding several hundred kilometers, this increase is indeed negligible.   However, Nissan offers another perspective: over a yearly period, for owners who primarily use the vehicle for daily commuting and frequently park outdoors, this system could theoretically reduce charging frequency by 35% to 65%.   This means that although the range increase each time is small, for car owners whose daily driving distance is not long and charging is not very convenient, the cumulative effect over time, this system can still bring real convenience and peace of mind.   Further Setbacks for Competitors: Mass Production Remains a Challenge Looking at the market as a whole, Nissan is not the only automaker attempting to equip electric vehicles with solar panels, but past cases have shown that the commercialization of solar-powered cars is extremely difficult.   Lightyear, a once-promising Dutch startup that planned to manufacture dedicated solar-powered electric vehicles, ultimately went bankrupt due to a broken funding chain and manufacturing difficulties; ...
