Since 2026, the US and EU markets have been raising compliance standards for PV energy storage equipment, making UL and TÜV certifications a must-have for domestic battery controllers to enter Western markets. This article explains the key requirements of UL 1741 and the latest TÜV Rheinland standards, and highlights how leading domestic manufacturers — including SRNE, EPEVER, and Muster — are leveraging dual certifications to access both North American and European markets, reduce compliance time and costs, and effectively avoid product rework and recall risks.

Many users find that their solar panels never reach the rated power — and often suspect false labeling. In fact, the rated power is measured under lab-perfect STC conditions, which are hard to achieve outdoors. This article explains three practical steps to close the gap: proper installation, system optimization, and regular maintenance — so you can get the most out of every panel.

The article introduces the relevant methods and precautions for snow removal in photovoltaic power plants: selecting high angle components during installation and reserving a ground clearance distance to prevent snow accumulation; Avoid using sharp objects and hot water when removing snow, do not step on components, and clean them promptly to avoid freezing. Small power stations can use soft cloth mops to push snow, while large power stations can choose robots to remove snow. Safety should be taken into account during operation.

P-type PERC cells were once mainstream, but their efficiency, attenuation, and low light performance have obvious shortcomings. N-type TOPCon/HJT has become the mainstream of the new generation, with advantages such as high efficiency, good weak light, low attenuation, strong weather resistance, high double-sided power generation gain, and low-carbon easy recycling. It is suitable for multiple scenarios, improves power plant revenue and lifespan, and promotes the efficient and low-carbon transformation of the photovoltaic industry.

Due to unstable power grids and frequent blackouts in the Philippines, users prefer integrated photovoltaic and storage solutions. These systems can generate electricity during the day and supply power at night, providing emergency backup during outages. They are more cost-effective and hassle-free than diesel generators, making them suitable for homes, shops, and island scenarios as a comprehensive power solution. Demuda has launched two integrated units with capacities of 3.6kW+6kWh and 6kW+16kWh to meet diverse load demands and adapt to the local market.
