Solar power is one of the ways to power a battery charger. It works better if you have full sunlight but even a small amount will do the trick. A solar panel or a photovoltaic panel as they are known work in a way that transforms sunlight into energy that can be used to power a charger. It works by converting the solar radiation into direct current electricity or DC power.
Photovoltaic panels contain a bunch of tiny little semiconductors that are made out of very brittle materials. That is why solar panels are expensive because they cost a lot not only to make but also to transport. They are brittle and susceptible breaking. There are some photovoltaic panels that are flexible and these are made out of very thin semiconductors.

The Deep Cycle batteries used in cars, RVs or Boats are designed to be discharged and then re-charged hundreds or thousands of times. These batteries are rated in Amp Hours (ah) – usually at 20 hours and 100 hours. Simply stated, amp hours refers to the amount of current – in amps – which can be supplied by the battery over the period of hours.
For example, a 350ah battery could supply 17.5 continuous amps over 20 hours or 35 continuous amps for 10 hours.
To quickly express the total watts potentially available in a 6 volt 360ah battery; 360ah times the nominal 6 volts equals 2160 watts or 2.16kWh (kilowatt-hours). Like solar panels, batteries are wired in series and/or parallel to increase voltage to the desired level and increase amp hours.

Photovoltaic panels are a good source of portable power to use for our devices and gadgets. Latest generations of solar panels are more powerful and employ less time for charging….for a wise investment.
You can use this kind to power or use solar to charge batteries for Ipod, Iphone, Mp3 Players, sometimes a laptop (depending on output of the panel), remote field testing, surveillance, small TV/VCR, video recorders, work lights, RV and Boat batteries.
