The bad side
It may take an extended time for batteries to charge. Solar power may not be as potent as its less efficient counterparts. It is important to note the wattage of the unit.

A big variety
Charging units for everyday things will be of great value. There are so many uses in the home. Remote controls, flashlights, and cameras are just a few.
There are also models made for your car, truck, or recreational vehicle. Some of these are simple to use. You plug them into a cigarette lighter socket. After that, you simply set them on the dash.

Some chargers will shut off by themselves when the batteries are charged. Others will not. If it does not, be careful not to overcharge the batteries. Most of them have a blocking diode. This prevents battery current from entering the charger.
Most of the sun-driven battery chargers are portable units. There are stationary units. However, they are usually very large for housing and such. The expense involved with those may be cost prohibitive.
