The Instruction manual shows how to purchase the individual solar cells on the web and connect them to make a working system similar to the ones that construction companies charge thousands to install in the home. The biggest difference is that you can produce them using this guide for less than a couple of hundred dollars with only a relatively small investment of time. The tools needed are those that can be found in any typical garage and toolbox. It might seem difficult, but you do not need to be a DIY expert to create the solar panels. No technical studies are needed. Like the cost, subject knowledge needed is kept to the minimum. Moreover, this easy job can be finshed within a month.
