I've mentioned in my other reviews that 200 watt solar panel units can cost as much as $1000 to $1500, but most of that cost is in labor or assembly. If you are willing to do the labor, (usually a weekend to put a couple of solar panels or 1 wind turbine together), you reduce your cost to much less than $200 rather than thousands of dollars. The assembly can be intimidating especially when you are working with expensive materials. I didn't want to break anything during assembly or hook it up the wrong way and ruin the whole project. That's why instruction videos are so important to me because it SHOWS me exactly how to do what the instructions, photos, and illustrations are telling me. The videos in the Green DIY Energy system are excellent and proves once again to me that you do not have to be a professional to make your own energy, anyone can do it!

If you decide to wire your energy system into your house, whatever electricity you don't use goes back into the grid. When you are generating more power than what you are using, your electrical meter will run backwards! If you've given back more energy than you've used your power company will pay you instead of you paying them. They don't pay nearly as much as you do however and you may want to store that power in deep cycle batteries. (Wiring your system into your local power grid will require installation by a certified electrician).
