How to build a Portable Solar Power Station
There are a lot of these types of solar projects out there on the internet. This DIY solar project is slightly different though, this is actually a decent one .. Its all boxed in and no nasty cheap looking wires hanging out from every nook and cranny.
This instructable has very detailed photos showing you how to build one for yourself. he uses a 400 watt converter but you can always add more batteries and have a bigger solar panel. It is very customizable. Remember you can use old and scrap stuff to bring the total cost down too.
