LEFENG High conversion 72xCells Polycrystalline Silicon Solar Module Premium Quality 156mm Poly Solar Panel 320~340W Photovoltaic Module
Product Detail
• Parallel connection use: if the voltage of the solar panel corresponds to your storage battery. To speed up the charge rate, you can switch two or more same solar panels together in parallel.
• Versatile purpose: very suitable for small home projects, scientific projects, electronic applications and other DIY projects with solar energy. Suitable for solar toys, lawn lights, wall lamps, radios, solar miniature water pumps, etc. for charging small DC batteries.
• High quality solar panel material protects against device failure due to environmental factors or manufacturing defects, very reliable.
• Warranty: 12 years PV module product warranty and 25 years linear warranty
— Product introduction:
High conversion rate, high efficiency performance, excellent low light effect. A locking diode already built in on the back protects the solar panel from overcharging and current backflow.
Adopts waterproof resin encapsulation that has good sealing performance and stable performance and is not damaged by rain or snow. High quality epoxy resin, unique technology to make the components beautiful and strong, against wind and snow, increases the service life of solar panels. Waterproof, UV and scratch resistant for more than ten years of outdoor use in all conditions
Use: solar garden lighting, small household lighting systems, solar street lighting, outdoor solar advertising, suitable for various low power electrical appliances, emergency lights, advertising lights, traffic lights, household lights, electric fans and other low power appliances.
