LEFENG Weatherproof High-efficiency Wholesale Grade A 144 Half-Cell Monocrystalline Silicon Photovoltaic Module TUV Certificated 535~555W 182mm All BLACK Solar Panel PV Module

Short Description:

The solar panel is highly efficient in converting solar energy into electricity thanks to its built-in monocrystalline silicone solar panel. It is also waterproof and durable, with EVA Film and Tempered Glass that offer superior waterproof performance and resistance to harsh weather conditions, heavy cold, and heat. The panel is constructed using high-quality A-grade solar cells, a surface made of high-transmittance tempered solar glass with weatherproof coating, and a corrosion-resistant BLACK aluminum frame with pre-drilled mounting holes for extended outdoor use. An IP68 junction box with a 30cm long 4mm² double insulated solar cable completes the construction.

Product Detail

— Product introduction:

• The module utilizes half-cell technology, resulting in higher power output and lower system costs. This technology also reduces the risk of hot spots, shading losses, and internal resistance.
• Solar panels have excellent energy conversion rates, efficiently absorbing solar radiation to maximize power yield and minimize carbon emissions, promoting energy savings and environmental protection.
• The module features superior craftsmanship and dependability, utilizing contact solar cells and a double anodized aluminum frame that offers excellent scratch resistance. Its crystalline cells are embedded in a 3.2 mm thick glass with low iron oxide and a high-strength double layer film.
• Ideal for both on-grid and off-grid applications in ecological houses, cottages, caravans, motorhomes, boats, and any other locations that require a self-sufficient and portable power supply.
• The module includes a 12-year warranty for PV module products and a 30-year linear warranty.
