Products Description
Exceptional Durability
The double-glass construction endows the solar panel with exceptional durability. Both the front and back surfaces being made of glass offer superior protection against various environmental factors. It exhibits excellent resistance to moisture, corrosion, and the erosive effects of sandstorms, acid rain, and salt spray. With a typical warranty period of 25 to 30 years, it ensures a long-term and stable power generation performance. The annual power degradation rate is usually kept below 0.5%, maintaining its efficiency over an extended period.
Superior Heat Dissipation
This structure of the solar panel contributes to its superior heat dissipation properties. During operation, the heat generated by the panel can be dissipated more effectively compared to single-glass panels. By reducing the operating temperature of the solar cells, the negative impact of high temperature on power generation efficiency is minimized. Especially in hot climates, it can maintain a relatively stable power output, enhancing the overall performance and reliability of the photovoltaic system.

FAQ
How do I clean this kind of solar panel?
Use a soft brush or sponge with mild detergent and water. Gently scrub the surface to remove dirt, dust, and bird droppings. Avoid using abrasive materials or harsh chemicals that could scratch or damage the glass surface. Rinse thoroughly with clean water and let it dry naturally. It is recommended to clean the panel regularly, especially in dusty or dirty environments, to maintain its power generation efficiency.
What is the temperature coefficient of the solar panel?
The temperature coefficient indicates how the panel's power output changes with temperature. For most double-glass solar panels, the power output decreases as the temperature rises. Typically, the temperature coefficient is around - 0.3% to - 0.4% per degree Celsius. This means that for every 1-degree Celsius increase in temperature above the standard test condition (usually 25 degrees Celsius), the power output of the panel will decrease by about 0.3% - 0.4%.
