— 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.
