LEFENG Weatherproof High-efficiency Wholesale Grade A 144 Half-Cell Monocrystalline Silicon Photovoltaic Module TUV Certificated 440~460W 166mm All BLACK Solar Panel PV Module

Short Description:

—The solar panel features a monocrystalline silicone solar panel built-in, which enables it to efficiently convert solar energy into electricity.

—It is highly waterproof and durable, thanks to its EVA film and tempered glass covering. This makes it capable of withstanding harsh weather conditions, heavy cold, and heat.

—It is made of high-quality A-grade solar cells, with the surface being composed of high-transmittance tempered solar glass with a weatherproof coating. Its black, corrosion-resistant aluminum frame is perfect for extended outdoor use, with pre-drilled mounting holes. Additionally, it has an IP68 junction box with a 30cm long 4mm² double-insulated solar cable.

Product Detail

— Product introduction:

• The module utilizes half-cell technology, resulting in higher power output and lower system costs. Additionally, this technology reduces the risk of hot spots, shading loss, and internal resistance.
• The solar panels have high energy conversion rates due to their ability to absorb solar radiation, improving photoelectric conversion efficiency and promoting energy savings and environmental protection. This maximizes customer value through increased power yield generation and reduced carbon emissions.
• The photovoltaic modules feature high-quality workmanship and reliability, including contact solar cells and a scratch-resistant double frame made of anodized aluminum. The crystalline cells are embedded in a 3.2 mm thick glass with low iron oxide and a high-strength double layer film.
• These panels are suitable for on-grid or off-grid applications in ecological homes, cottages, caravans, motorhomes, boats, and other locations that require a self-sufficient and mobile power supply.
• The product includes a 12-year PV module warranty and a 30-year linear warranty.
