FAQ

A solar system using batteries for storage can "ride-out" utility blackouts. Batteries add significantly to the expense of a system while providing no payback, need weekly maintenance, are hazardous and will need replacing every five to ten years. For this reason most city dwellers are opting for a "grid-tie" system.

As systems get larger, the cost per watt is lower. A two (2) kilowatt system may cost between $16,000 and $20,000 ($8.00 to $10.00 per watt), while a five (5) kilowatt system may be installed for as little as $35,000 ($ 7.00/watt). All of these prices are figured before the rebates or tax credits. The final cost may be as low as $2.50 per watt (or $12,500 for a 5 kW system) depending upon which incentives your utility may offer.
