Recently, Musk’s team’s inspection of China’s photovoltaic industry and his plan of building a 100 GW space solar satellite network have made space photovoltaics a heated concept. Space photovoltaics features higher solar energy density without day-night or weather limits, but it is still in the early exploration stage with huge long-term potential. At present, it is restricted by high costs of core materials and power generation—its electricity cost is nearly 100 times that of ground photovoltaics—and faces great challenges in industrialization and economic viability. Benefiting from strong R&D, manufacturing capacity and cost advantages, China’s photovoltaic industry accounts for a dominant share globally. Leading Chinese PV firms are actively carrying out cutting-edge R&D in perovskite, tandem cells and space-related labs. With future breakthroughs in launch costs and commercial space technology, the trillion‑level space PV market is expected to become viable. Read More

During the "14th Five-Year Plan", China's PV industry achieved leapfrog development: manufacturing output value over 1 trillion yuan, exports over 180 billion US dollars, and cumulative installed capacity entering the terawatt era. Its new installed capacity has been the world's first for 13 consecutive years, with two phases: rapid growth and adjustment. Technological innovation advanced, and industrial chain prices dropped sharply. For the "15th Five-Year Plan", global average annual new installed capacity is expected to be 725-870 GW, China's 238-287 GW. Notably, 2026 new PV installed capacity may drop 23.8%-42.9% year-on-year (first decline since 2020) due to policy wait-and-see, but will recover from 2027. The industry will shift to value competition; the April 2026 PV export tax rebate cancellation will increase costs, accelerate capacity clearance and force technological innovation, focusing on intelligent, green and integrated development to maintain global dominance.

There are various ways to install photovoltaic modules to adapt to different environments and requirements. Here are several common installation methods for photovoltaic modules:1. Roof installationFlat installation: Photovoltaic modules are directly laid on the roof, parallel to the roof. Read More

On Feb 5, the key PV industry symposium – 2025 Development Review & 2026 Outlook – took place in Beijing. A clear message was sent: the sector will prioritize curbing cut-throat competition in 2026, with the growth rate of domestic installed capacity set to pull back. Read More

This practical guide helps beginners avoid pitfalls in PV inverter selection. It highlights inverters’ core role as PV systems’ "energy heart" and focuses on three key aspects: power matching (0.8~1.1 ratio with solar panels), four inverter types (emphasizing 2025’s mainstream string and growing energy storage ones), and brand selection (scenario-based leading brands, three red lines, no blind pursuit of imports). It also provides a minimalist process, stressing "adaptation" over "high price" for long-term stability. Read More

This article focuses on the frequent severe weather such as heavy rainfall and thunderstorms during the flood season, which pose potential safety hazards to outdoor PV systems. It elaborates on the core protection measures for PV system waterproofing and lightning protection: waterproofing protection mainly targets key seepage-prone areas such as module connections, inverters, distribution boxes, lines and junction boxes, emphasizing adequate sealing, unobstructed drainage and timely inspections; lightning protection follows the principle of "all-round protection and graded current discharge", covering external interception, internal overvoltage suppression and grounding protection. In addition, it provides emergency response methods for potential hazards during the flood season, aiming to help household and industrial/commercial PV users safeguard power generation safety, avoid equipment damage and extend service life.
