Recently, meteorological agencies in multiple countries have issued high-level warnings, indicating that a "super El Niño" that could reshape the global climate pattern is rapidly approaching from the end of 2026 to the beginning of 2027. For China's photovoltaic industry, this means that extreme weather events such as typhoons, strong gusts, and blizzards are transforming from "black swan" events into "gray rhinos." As the core power generation unit of a power plant, the adaptability to extreme environments, structural stability, and load safety of solar panels will directly determine whether they can withstand countless extreme weather events throughout their 25-year lifespan. However, a recurring but often overlooked industry issue is that the shortcomings of ultra-large-size photovoltaic modules are becoming increasingly apparent under normalized extreme weather conditions. Their comprehensive ability to cope with harsh operating conditions has become a critical issue that urgently needs to be examined.   The "Triple Blow" of El Niño El Niño is not an abstract meteorological term, but a crucial test that photovoltaic power plants must face. When global atmospheric circulation becomes abnormal, my country's densely populated photovoltaic (PV) installation areas are facing the combined impact of three extreme weather events: First, frequent and intensifying typhoons and strong gusts. The number of typhoons forming in the Pacific has increased, and their landfall intensity is stronger than usual, significantly raising the probability of severe convective weather in coastal and inland areas. For PV power plants, this means that repeated alternating gusts have become the norm, and the modules are no longer subjected to single wind pressure events, but rather to high-frequency dynamic fatigue. Second, extreme heat waves. The number of days with extreme high temperatures in summer is increasing, and the surface temperature of modules frequently exceeds 70°C. The difference in thermal expansion coefficients between glass, frames, and cells is amplified at high temperatures, leading to a continuous increase in internal stress accumulation. Third, extreme precipitation and blizzards. The increase in torrential rains and floods in the south and extreme blizzards in the north significantly increases the probability of non-uniform loads on the module surface, while high humidity accelerates material aging. These three characteristics correspond precisely to the three fatal challenges facing PV power plants: dynamic fatigue, thermomechanical stress, and non-uniform ultimate load. Ultra-large modules are almost entirely failing in all three dimensions.   The Physical Dilemma of Ultra-Large Modules: When Area Expansion Meets Natural Laws Ultra-large modules, measuring 2384mm × 1303mm and above, have a total area of ​​3.1㎡ and above, representing at least a 15% increase in area compared to the industry standard module'...

According to a report by the European Observatory for Climate Neutrality (ECNO), a combination of factors, including grid bottlenecks, permitting delays, and limited flexibility, is slowing the growth of solar PV and wind power in Europe's energy mix.   This think tank's flagship annual report, which tracks progress toward carbon neutrality in Europe, shows that while the share of fluctuating renewable energy in Europe's electricity generation is expected to reach 30% by 2025, growth since 2020 has been "too slow" to meet the EU's target of 58% by 2030.   Although the total new installed capacity of wind and solar power in 2024 reached approximately 70 GW, in line with expectations, the report points out that this growth was primarily concentrated in solar power, reaching 57.5 GW. Wind power installations in 2024 were about 2 GW lower than in 2023, and because wind power has a higher capacity factor than PV (i.e., generates more electricity for the same installed capacity), this slowdown resulted in a much larger-than-expected decline in overall renewable energy generation.   ECNO identifies several factors contributing to this slow growth. The report states that grid investment, battery storage, and the adoption of smart meters remain insufficient. It also emphasizes the need to expedite approval processes, strengthen integrated grid planning, and provide stronger incentives to promote the flexibility of non-fossil energy, thereby elevating renewable energy to the required level.   For example, while European grid investment continued to grow from 2020 to 2025, the pace of progress remained too slow. The report estimates that the distribution network sector alone needs an annual investment increase of 12% to 25% to meet the demands of renewable energy development.   Although battery storage capacity has been increasing on the supply side, it remains below the level required by the European Commission for 2030.   Meanwhile, EU and member state policies have made inconsistent progress in supporting renewable energy development. Some EU-level policy initiatives, such as the Net Zero Industry Act (NZIA), provide an "important framework" for renewable energy, but in other areas, policy support has been limited.   Regarding the power grid sector, the European Climate Neutrality Observatory points out that the EU's power grid governance system is fragmented, with top-level EU rules, national regulatory systems, and member states' responsibilities disconnected. Power for grid financing and planning decisions is primarily held by individual member states, hindering the formation of a unified approach.   The report also notes: "Therefore, recent EU guidelines and legislative proposals on accelerating grid and energy storage approval processes and designing electricity pricing to incentivize efficient electricity use and end-user flexibility are crucial, but currently insufficient."   In response, the report emp...

A recent report by the UK-based energy think tank Ember shows that Pakistan added 27 GW of distributed photovoltaic (PV) capacity over the past two years, directly driving a 21% increase in the country's electricity demand.   Ember points out that between fiscal years 2023 and 2025, Pakistan's electricity demand is expected to grow by 33 TWh, with this increase entirely met by distributed PV generation. PV power generation has more than tripled, from 15 TWh in 2023 to 51 TWh in 2025.   Government grid generation declined by 3% during the same period, meaning that the share of distributed PV in the national electricity mix has also nearly tripled, rising from 10% to 28%.   This growth coincides with Pakistan's GDP growth of 5.2%. Ember states that distributed PV has brought the country's electrification rate close to the global average: the global average electrification rate is 22%, while Pakistan's is currently at 21.7%, an increase of 5 percentage points in two years, compared to a global average increase of only 0.8 percentage points during the same period.   Ember states that the 27GW of new installed capacity added between 2023 and 2025 is equivalent to the total capacity of all natural gas, coal, and oil-fired power plants ever built and put into operation in Pakistan. The report also notes that distributed photovoltaic (PV) installations are fast and inexpensive, making it the only technology capable of so profoundly changing Pakistan's energy landscape.   Ember's chief analyst, Dave Jones, stated, "Pakistan has strong energy demand, and PV perfectly meets this demand. Distributed PV installations are fast and cheap, even directly driving electricity demand growth. Many other emerging market countries also have pent-up energy demand, hampered by the problems and high costs of fossil fuels. The explosive growth of distributed PV in Pakistan provides experience demonstrating how quickly clean energy can grow and what benefits it can bring."   Ember data shows that by 2026, new PV installations have saved Pakistan over $12 billion in oil and gas import costs, while supporting economic growth in the country's agriculture, industry, and commerce sectors.   Data jointly released by Ember and Renewables First shows that Pakistan's total installed distributed photovoltaic (PV) capacity has reached 38 GW; as of June 2025, cumulative PV module exports from China to Pakistan reached approximately 47 GW.   Besides price and ease of installation, the booming development of Pakistan's small-scale solar industry has also been driven by the ripple effects of the 2022 European energy crisis. This crisis led to soaring electricity prices, grid problems causing power shortages, and a "generous" net metering policy—which, until recently, greatly incentivized the adoption of solar energy.   However, the report points out that currently, net metered solar power accounts for only a "minority" of Pakistan's insta...

The newly released 17th edition of Intersolar Europe's International Photovoltaic Technology Roadmap (ITRPV) shows that despite facing multiple challenges such as overcapacity and significant price fluctuations, the global photovoltaic industry continues to demonstrate strong resilience in technological iteration and cost reduction.   This authoritative report, jointly compiled by 38 leading companies and research institutions across the global crystalline silicon photovoltaic industry chain, comprehensively outlines the industry's technological iteration path, clearly demonstrating that the industry is fully shifting towards higher efficiency while continuing the decades-long "learning curve" pattern of cost reduction.   The report points out that the industry's learning curve will increase to 26% from 1976 to 2025; N-type cells will fully replace P-type PERC, silver consumption will reach a historical turning point, and silicon perovskite tandem cells will achieve mass production in 2027.   Key Indicator: Industry Learning Curve Rises to 26% A key conclusion of this edition is that the photovoltaic industry's learning rate will increase to 26% from 1976 to 2025, compared to 24.9% in the previous edition. This indicator represents the decrease in unit cost of modules for every doubling of cumulative installed capacity in the industry. It confirms that even with overcapacity and fierce price competition in the past two years, the underlying logic of photovoltaics—relying on technological innovation to continuously reduce production costs—remains unchanged. In 2023 and 2024, the industry experienced a sharp drop in module prices due to overcapacity. By the end of 2025, prices stabilized and rebounded slightly, with the end-user price at approximately $0.09/watt, an increase of $0.01 compared to the end of 2024. The core driver of this price recovery was the implementation of domestic energy regulation policies, which tightened new capacity expansion across the board, balancing the severely oversupplied market. Major Technological Migration: N-type Completely Replaces P-type, BC Technology Achieves 28% Market Share in Ten Years. The solar energy industry is experiencing a fundamental technological iteration inflection point. The report confirms that in 2024, the market share of N-type TOPCon officially surpassed that of traditional P-type PERC, and the replacement process accelerated comprehensively in 2025. In terms of efficiency: Current mass-produced TOPCon solar panels achieve an efficiency of 23.5%, on par with HJT; TOPCon back-contact (TBC) modules lead the industry with an efficiency of 24.1%; traditional P-type PERC modules only reach 21.7%. Meanwhile, high-power, bifacial, and N-type modules have shed their high-end premium attributes and become the mainstream in the market. Almost all new capacity is being invested in N-type routes such as TOPCon, HJT, and IBC back-contact, with only a small number of newly buil...
