Solar power accounts for only 1% of the power usage in the United States. But is it practical? The video below is a good overview of where solar power is right now and where it is going. There is not much worry about safety products with the installation, but an average install can cost about $80,000 and this is after your incentive rebates. CoolerPlanet.com has an online calculator to help you determine how much it would cost to install solar power in your home. It would cost me $70,000 and I would not see a break even point for at least 11 years. This costs is far greater than the average homeowner wants to spend.
