— 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.
