Solar chargers for batteries have become a common consumer item. Building one on your own can be a good introduction to solar electricity and can save money on buying one of the more expensive commercially available battery chargers. Batteries usually require 1.2 or 1.4 volts to charge, according to the Solar Power Fast website.Typical small solar panels produce 0.5 volts, so a good rule of thumb is to have three solar panels per battery charged. The process is relatively simple, involving mounting a solar cell to a backing and connecting it to a battery holder to allow it to charge the battery. Construct a backing out of glass for the solar panels. One option is to use an old window that you have cleaned to ensure the light can pass through. Arrange the solar cells on the window or glass to determine the best configuration for your surface. Solar cells usually will have a backing that will allow you to connect them to the glass surface. Solder the cells that are in a single row togeth
