5V 1.21W 220Ma Mini Solar Panels With Cable, 110 X 80Mm

What is this?Small solar panels, also known as solar chips or photovoltaic cells, are devices that use sunlight to directly convert it into electrical energy through the photovoltaic effect. They are suitable for home lighting and various low-power electrical appliances, solar water pumps, solar cars, etc. You can also use it to make various DIY components, such as solar models, toys, displays, light strings, etc.What will I get?Polycrystalline Solar Panels with CableSize: 110 x 80mm/4.33“ x 3.15“(L x W)Power: 1.21WVoltage: 5VCurrent: 220mAIn the Package: 1Pcs x Mini Solar PanelsAre there any advantages of the product?1. The use of solar panels can reduce the use of chemical fuels and help reduce greenhouse gas emissions.2. This mini solar panel is made of conductive copper and resin, which is small and lightweight, durable, compatible, and has high conversion efficiency. It is wind and snow resistant and can be used outdoors.How to use it?The mini solar panel's positive and negative poles come with 2 welded wires. They can be directly connected to other low-power appliances or small projects through two wires, which is very convenient to use. You can install two or more solar panels with the same parameters in series or in parallel.What should I notice?You need to choose the appropriate solar panel according to the voltage, current, power, etc. of the load; at the same time, solar panels need to be used with batteries to store electricity.
