Earth 4 Energy Review – Can Earth for Energy Really Convert Your Home to Solar Power?

Posted by admin on April 15, 2013 in Renewable Energy with 5 Comments

You can convert your home into solar power. By using solar system to generate electricity does make your home stand out. Solar energy or Renewable Energy can help you to save your electricity cost by 60% annually. A single house with 2 solar systems is sufficient for daily power usage. But the problem is a solar power system cost more than $1000. In this article I will show you the way of how you can get a home-made solar system for less than $200.

Earth 4 Energy is a website which offers a web-based program teaches how to build a home-made renewable energy generator. A solar power is enough to produce electricity for 3 heaters. It is also depend on the size of the solar plate. Each house should need at least a 2 kilowatt solar power system. The exceeding of electricity which isn’t use can be sold to a local power utility company.

2 meters are required to record the solar power which being used and another to record how much electricity did the solar system generated. As a result the electricity cost is less than $10 per month which reduces the utility expense by 60%. So you won’t have to worry about how much you have to pay for the bill. A solar system not only helps to keep the environment green but save a lot of money for you. As mentioned earlier, a solar system is costly. Earth 4 Energy is a D.I.Y. home-made solar system the program show you how to build a solar power device for less than $200. In fact you can buy parts from your local store or on the internet.

The program offers an instruction manual and videos show you how to build the system in detail. The process is explained in basic steps. The program is designed for people who have no basic knowledge about renewable power system and does not based on technical content. An experienced person can use the program for new ideas and tweak their skills. Earth 4 Energy offers a cost-effective way to build home-made renewable energy system for every household.

Let me show you how to successfully create a solar system for less than $200
