How much will cost me to power my home with solar energy?

Solar electricity costs about $10 to $12 a watt installed, though you may be eligible for state incentives. The fact is that the cost of photovoltaic panels and solar systems in general is constantly dropping, and more and more people start using solar energy to power their homes.
Is Solar Energy a good investment?
A solar thermal system benefits you by heating your water and pays for itself in two to three years depending on your location. A solar pool heating system for your pool or hot tub also pays for itself in two to three years.
By using energy conservation techniques to reduce energy needs and by adding some passive solar basics you can cut your energy requirements in half. Also there are incentive programs available in nations around the world, many of which will decrease your solar power cost by as much as half.
Of the over 1.5 million Americans who have invested in solar hot water systems for their homes and businesses, over 94% consider the investment a wise decision.
