Solar electric systems cost on average $7.50 to $9.50 per AC watt
installed, which includes system design, materials, and labor. Market
research of both solar technology and installers can help you to
compare individual component prices and project bids and empower you as
a consumer.
Rebates and Incentives.
Once your project has been installed, you can enjoy savings with state and federal incentives.
California Solar Initiative (CSI).
Grid-connected systems smaller than 30kW may qualify for a one-time
incentive from PG&E as part of the CSI's Expected Performance Based Buy Down (EPBB) program. For projects larger than 30kW, CSI's Performance Based Incentive (PBI) pays out an incentive over a period of 5 years based on a $ per actual kWh produced. The most up-to-date information on rebate amounts within PG&E territory can be found here.
Financing Strategies.
You may be able to finance your solar electric system with a monthly
payment that is less than your current monthly electric bill. The most traditional option is a small business loan. Solar companies have also developed financing
strategies that include solar leases and power purchase agreements. In
deciding how to pay for your solar system, consider contract
obligations, whether interest payments are tax-deductible, how
incentives are packaged, and the treatment of your Renewable Energy
Credits (which are certificates for the clean energy produced by your
solar system and which may have monetary value).
