5pcs 2V 150mA Polysilicon Solar Panel Glue Solar Cell Battery Charger DIY Solar Product Mini Small Solar Panel Module Kit Polycrystalline Silicon Encapsulated in Waterproof Resin (150mA)

Polysilicon solar panel is one kind of solar panel but in different package.

Through cutting solar cells into small pieces to meet different required voltage and current, then package.

Using epoxy resin glue to cover the solar cell and with PCB(Printed Circuit Board) attached, have the feature of resist compression, corrosion resisting, crystal-clear appearance, low cost, etc.

Encapsulated in waterproof resin so it should not be affected by rain or snow.

Solar panels are devices that absorb sunlight and convert solar radiation directly or indirectly into electricity through photoelectric or photochemical effects, which is perfect devices for science project.

Solar panels can link together in parallel or series to speed up the rate of charge to max the voltage power in order to match the storage battery of your DIY solar products.
