Using a solar panel to charge power bank.

With the need for more power the usb implementers forum released the battery charging specification in 2007 that enables a faste. A solar power bank uses a small built in solar panel to charge a rechargeable battery usually a lithium ion battery. 6v is a nominal voltage and actual v oc will vary widely depending on irradiance and load. The solar power generated by the solar panel is received by the solar charge controller.

Most usb power banks will work with most solar panels with a usb output rated at 5v 200ma. Free electricity is great and as long as your solar panel does not break you can harvest the sun s energy for as long as you want. If you want to use it to charge your ipad in an hour think again.

Free electricity solar panel chargers provides free power from the sun.

The panel is a photovoltaic cell which is sandwiched between a semi conductive material usually silicon.
