After we moved into this big house last year, pretty soon we realized that our energy bill was through the roof. With the high ceilings and the pool etc. it was a no brainer. after changing all the bulbs and appliances to energy efficient ones, still the bill was pretty high. Spoke to few people and friends at work and found out going solar was the way to go. Not just it will pay it off completely in about five years but also its clean and and has no carbon footprints. After it pays off itself, you can enjoy this free and clean energy for years to come. Its a WIN WIN situation!
