40W Single Crystal Solar Panel

The 40W monocrystalline solar panel utilizes high-efficiency monocrystalline silicon cell technology, achieving higher photoelectric conversion efficiency than conventional polycrystalline silicon modules. The panel is constructed from 36 monocrystalline solar cells connected in series, with a standard operating voltage of approximately 18V, suitable for charging 12V battery systems. The panel is covered with low-iron tempered glass, offering high light transmittance and impact resistance. It also incorporates a PID (potential-induced degradation)-resistant encapsulation process to minimize environmental degradation. The backsheet is made of weather-resistant TPE, offering water, dust, and UV resistance. The aluminum alloy frame provides stable support and corrosion resistance, making it suitable for outdoor photovoltaic systems, off-grid power generation, and small home power supply applications. The operating temperature range is -40°C to 85°C, meeting typical durability requirements.
