China has issued intensive policies to boost large-scale wind and solar bases amid the 15th Five-Year Plan. Against a downturn in domestic PV installations and grid consumption pressures, these centralized bases supported by UHV transmission have become a vital choice for industrial structural upgrading. Multiple major projects are underway, yet challenges such as insufficient power transmission capacity and multi-energy coordination remain. The base construction will underpin energy security and low-carbon transformation to stabilize the PV industry. Read More

Solar cell modules are the core energy conversion units of photovoltaic (PV) systems, and their quality directly determines the efficiency, stability, and service life of PV systems. To ensure module quality and avoid potential hazards, the industry has established strict testing standards. This article systematically analyzes the core testing requirements of solar cell modules from five aspects: appearance cleanliness and cell integrity, cell chipping and corner defect control, grid line and bus bar connection reliability, assembly clearance and displacement precision, and solder ribbon and grid line connection sealing. It also elaborates on the industrial significance and application value of these requirements, providing technical reference for module production, quality inspection, and application, and promoting the standardized and high-quality development of the PV module industry.
