SunPower PV systems usually start at $10,000, but Sun First! Solar is happy to provide a free on-site analysis and explanations of the costs associated with installing new solar panels, as prices vary. The modules themselves start at $6.85$7.75 per watt, additional costs vary based on the characteristics of the house's roof, wiring, system size, and garden-gnome population. For instance, Sun First! Solar charges an additional $0.70 per watt to install on a slate roof and an additional $0.30 per watt if the roof is corrugated metal; additional charges are incurred if a roof slopes more than 30 degrees ($0.35/watt) or rises higher than two stories ($0.25/watt). Greater additional costs are related to ground layout and electrical service. Whatever the cost of their system, homeowners can often recoup a portion of their installation costs through federal- and state-tax credits within a year of their purchases.
