With a PV solar system, the cost of electricity remains constant over the lifetime of the system (up to 25 years).   If more electricity is produced from the PV system than the home needs, the extra kilowatts are fed into the grid and "sold" to the electrical utility.   Significantly reduces the cost of electricity provided by the utility company.   At the Federal and State level, new system installations are eligible for financing, tax incentives and rebates.   Increases home values   Highly reliable; and needs little maintenance   Does not produce carbon dioxide emissions; is an environmentally responsible renewable resource   Contributes to nation's energy security by reduced dependence on utility generated power and supplies of foreign energy products
