HOW MUCH DOES A GRID-TIED SOLAR PV SYSTEM COST?
A. Many factors determine the final cost of a grid-tied PV System, such as: system size, type of mounting system, roof material and pitch, wiring runs and various other installation details. At present, a typical roof-mounted PV System costs from $7 to $9 per watt (Dc input) before rebates and tax credits. For example, a 2.5 kilowatt grid-tied system (approximately 2,880 to 3,200 DC watt input) will cost $22,000 to $28,000 before state rebates and tax credits. California state financial incentives are available now, making your probable final cost between $14,000 and $19,500. As both equipment costs and rebates go down, there will be changes in the final price to the purchaser. Currently, rebates are dropping faster than equipment costs. So, there will never be a more cost-effective time to buy than right now.
