I constructed the prototype in about 2 hours. The initial charge lasted 12 hours but it has been showing low power since. The output on the panels was only 9V and i believe this is the issue that is causing the batteries to not change. I have hooked the panels up in parallel to combine the current or 6watts.
My next set is to measure the output of the panels in full sunlight and take a lumen reading as well. If the voltage is low (assuming 3v) I will add the need voltage amount (3v) with that type voltage solar panel (3v) in series to make the needed 12v.
