Polycrystalline silicon solar panels are a kind of solar panels, but the packaging is different. By cutting solar cells into small pieces to meet different voltage and current requirements, they are then packaged. Solar panels are devices that absorb sunlight and convert solar radiation directly or indirectly into electricity through photoelectric or photochemical action, and are ideal equipment for science and engineering. Solar panels can be connected in parallel or in series to speed up charging and maximize voltage power to match the battery of your DIY solar product. We offer a variety of voltage solar panels for you to choose from, such as 0.5V, 1V, 1.5V, 2V, 3V, 3.5V, 4V, 5V, 5.5V, 6V, 9V, 12V, 18V, and USB connected solar panels. Build your own power model, solar toys, solar lights, solar displays, charging small DC batteries. Solar DIY product applications: solar lawn lights, solar wall lights, solar crafts, solar toys, solar radios, solar aluminum flashlights, solar charging banks, solar mini water pumps, etc. Date First Available March 8, 2024
