But the difference between buying and doing it by yourself is, that you save much more money when you build your own solar panel which could be easily build because nowadays the knowledge and the material is available everywhere. The information you need to make your solar panel,  can be gathered on the internet. But if you don’t have the time to gather all those information then you have the possibility to buy an electronic book. This book explains step by step how to make a solar panels. They also tell you where to find the material you need and where they are cheaper. Mostly they cover the whole process and I found not expensive at all.

Sometime is better to buy a ready solar panels, specially if you don’t have the time to do it.  But for me, its my hobby and I enjoy doing it. When ever I have a time, I always reserve sometime to build those solar panels. I am quite happy if I make one in month. Actually it’s possible to make one solar panel in two hours if everything ready for you but I am also quite busy with other things.
