Solar Battery Charging

Step 7SOLAR BATTERY CHARGING FACTS

The maximum output of the solar cell is 150ma. This is with the best conditions. A high capacity rechargeable Nimh can hold 2000mAH. This means that it would take ( 2000/150 ) hrs to fully charge it. This is about 13hrs!

a) How many batteries do you want to charge at once
b) How fast do you want them to charge.

By adding extra solar panels one can charge more batteries, charge batteries faster or even both at the same time.
