Earth4Energy is one of the first renewable energy guide to emerge in the market. Since its launch, many families have used the guide to build their own power systems. We decided to give Earth4Energy the top spot over Earth Energy For Home because it has been around longer.
The energy savings is reasonable. All parts used can be bought conveniently and assembled for less than a few hundred dollars. For less than $200, you can set up a single solar panel power system or a wind turbine.
However, there is some missing information such as how to calculate your energy consumption at home, how to determine the solar power output and the power output of wind turbines which we could find in Earth Energy For Home. It's not critical but we felt we need to mention it.
The guide provides a few videos that show you basics such as how to solder the solar panel together, etc.
You will also receive a bonus guide which we found quite useful.
