The solar generator you are speaking of has to be a much bigger deal than my setup is. Mine is 20 watts and it will charge four AA batteries in about an hour I think it is. Mine charges all batteries, even 9 volt ones. A solar generator, however, must be really large and there must be a large battery to store that energy and connect to that battery to run larger equipment like a refrigerator or a room air conditioner. That would be great to have.
