Why we use silver solar panel? Because black one absorb too much heat and will become very hot and reduce the efficiency of the solar panel drastically.

Can generate 20~40 Wh electricity per day. Suitable to work as a maintainer for a motorcycle battery, or as a maintainer for a car/boat battery which is less than 12v 60AH in area which has good sunshine.

If works as a battery charger, this panel can full charge a 12v 4AH battery in one sunny day.
