I saw this great little DIY project, great for down the garden in a shed or slimier to power lights and small items, make from plywood and has 12v power output.First let me start by saying this is not a plan on how to exactly build an Off Grid Solar System. Depending on what type of solar module or modules you use or what type of charge controller and battery you use. will determine the amount of power you will be able to get. but for a portable solar generator you would only want to charge a few devices or a light. Check out this portable solar generator below.
