5Pcs 5V 0.15W 30Ma Mini Solar Panels, Solar Photovoltaic Power Cells

What is this?Small solar panels, also known as solar chips or photovoltaic cells, are devices that use sunlight to directly convert 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.What will I get?Polycrystalline Solar PanelsSize: 44 x 24 mm/1.73" x 0.94"(L x W)Power: 0.15WVoltage: 5VCurrent: 30mAIn the Package: 5Pcs x Mini Solar PanelsAre there any advantages of the product?1. Energy saving and emission reduction: Using solar panels can reduce the use of chemical fuels and help reduce greenhouse gas emissions.2. Independence: Solar panels are limited by natural conditions and are suitable for different projects. You can DIY as much as you want, such as: solar-powered models, solar toys, solar displays, solar lamp strings, etc.How to use it?Mini solar panels can be installed in series or in parallel. You can use two or more solar panels with the same parameters in series or in parallel. Series means equal current and added voltage, while parallel means equal voltage and added current.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.
