1. Make sure that your charger is powerful enough.

2. Make sure you have adequate sunshine (at least 4 hours a day)

3. Make sure your charger has a controller to stop overcharging the battery

4. Make sure that there is room for extending the existing solar panel

Purchasing different solar panels for many devices doesn't make any sense but investing in one quality solar power kit is well worth it with a solar battery controller which stops charging when the battery is full. Buying an extra solar panel for about $60 can provide extra wattage for your battery charger.

Many people find that it is worth leaving a battery on charge continuously as this gives extra life to the battery. For example, a solar 12 volt battery charger for use on car would be best installed on a car dashboard for maximum efficiency.
