How does the 25 watt solar panel work?

The ACOPOWER 25 watt  Polycrystalline  module is meant for charging of smaller 12 volt batteries and for smaller appliances. Turn the surface to the sun and it operates.

The panel produces DC voltage. To use it for AC an inverter is necessary. Use a charge controller when charging a battery.

The panel output must be matched with the controller you use.

Six hours of sunshine per day gives you  6 x 25 = 150 watts per day.

If you have to charge a 48 amp hour car battery that drains to 50% you will need 12 x 48/2 = 576/2 = 288 watts. The 25 watt solar panel will need two sunny days to charge a small car battery.

Some of the “not so hands-on” people suggested an easier way to mount the panel. They suggested a hook or type of mounting bar for easier mounting.

Mentioning some facts

Rough handling with transport or installation may break the solar panel, and void the warranty.

The package does not include a mounting bracket.

A good idea from one buyer was the installation of a carry handle on one side of the frame for the convenience of carrying...
