This is my small 45 watt solar system that I cobbled together out of parts from here and there. All the output from the inverter is going through a watt meter so I can keep track of my usage. I have 170 A/hr of battery storage, a 750 watt power inverter, three 15 watt Harbor Freight solar panels and a 15 amp battery charger that I can plug into the grid or my generator if the power is out. Certainly will keep the Wii going in a ice storm.

What Is Earth4Energy?
Eearth4Energy is a comprehensive DIY guide on how to make solar panels. It covers all the basics of building a homemade solar panels successfully, that even a beginner or complete newbie without previous knowledge will be able to learn making his solar panels.
It has a dedicated video training for beginners, which covers comprehensive topics about solar energy. The training alone is worth buying, and probably one will learn more quickly than going back to school. If one has previous knowledge of basic electricity, this is a vital refresher and prepare one in using a whole new way of generating electricity.
================================
Benefits Of Harnessing Solar Energy/Power
================================
1. It is a clean energy source, no carbon footprint and no pollution.
2. It is renewable, and supply is abundant and available at anytime.
3. Since it is clean, we help maintain a clean environment.
Nowadays, several developed countries in Europe, the U.S., some countries in Asia and Africa have started to use solar energy as an alternative source of electricity. Just recently, the United States president had helped launched the biggest and largest scale solar energy plant in US. called the “Smart Power Grid”.
For the average homeowner, there is another huge benefits when using solar energy at home. Besides it significantly cuts the electricity bills, homeowners have the opportunity to earn money by selling the excess energy generated by the homemade solar panels to the electricity company. This is called “Net Metering”.
However, installing a solar energy system at home can be costly, upwards $20,000 if installed through a solar power company. Today, Earth4Energy has broken that barrier. Earth4Energy’s training is comprehensive.
===================================
Benefits Of Learning How To Make Solar Panels
===================================
1. Cheap when compare to commercially-made solar panels while achieving the same results.
2. Build your own solar panels at your own pace. Start small and progress to more solar panels until it will be able to power the entire home, making it possible to live off-the-grid.
3. When more energy is produced, the excess energy can be sold to the local electric company for profit. This process is called net metering.
In addition to the video training, which is about 2 hours long, it provides the comprehensive PDF manual on the actual instruction on how to make solar panels. This is a complete blueprint, along with it are parts list of what are necessary in building the panels. Moreover, it has a list of resources where the parts can be obtained.
Therefore, when you read the guide and prior to beginning the actual work on making the homemade solar panels, you already have the complete picture of what are the necessary parts, where to get those parts, as well as the convenience of learning how to make solar panels on your own.
Below are additional useful links should you decide to learn more about Earth4Energy. Learning and gaining the knowledge about how to make solar panels is a rewarding effort, plus the benefits of saving both energy and money.
