Solar Frequently Asked Questions (FAQ)

What types of rebates are available for solar?

All California residents that receive utility service from their regional provider are eligible for the following solar incentives:

  1. 30% Federal Investment Tax Credit (ITC) for both your solar electric and solar water heating systems, to be applied to your tax liability in the year of installation. If needed, you can carry over your tax credit. Please consult with a tax advisor for more information on the carry over. There is a projected stepdown to 26% for the tax year of 2020 and 22% for the tax year of 2021. After the tax year of 2021, the ITC moves to 0% for residential and 10% for commercial projects.

  2. Any PG&E Gas customer is eligible for a CSI Solar Thermal Rebate with the purchase of a solar water heating system for their house domestic water usage. Rebate is $29.85 per expected therm output on an annual basis.
What does solar cost?

Solar Electric Systems average between $2.60 – $4.50 per DC watt and will vary in payback base on how much you currently pay for your electricity as well as how much you want to lower your utility service. Solar Water Heating can pay for itself in 3 years or less. Typically, these systems are installed for under $4,000 (after incentives) and can reduce your monthly hot water heating bill up to 75%. Learn more about this technology with 8 Things to Know about SWH. Solar Pool Heating is the most environmentally friendly and inexpensive way to heat your swimming pool and can extend your swimming season up to 3 ½ months. If you heat your pool with a gas heater, you will recover your costs in less than 2 years. See more about Solar as an Investment.

Is my home right for solar?
Homes with an open roof space facing south, west or southwest are usually good candidates for solar. In addition, having limited shade on the property will give you a higher yielding production from your system. Solar Water Heating is a great option for homeowners, as about 75% of a family of four’s hot water needs is met with as little as 8’ x 12’ roof space.
Will my property tax increase?
Solar upgrades will not increase your property taxes. However many homeowners with solar have experienced an increased appraisal values because homes with energy efficiency upgrades are selling for between 7-20% more than a home without upgrades.
How long do solar systems last?

Solar Electric systems have multiple product warranties. Typically modules have 25 year limited production warranties up to 80% at the end of 25 years. They also have product warranties from 10-12 years. Inverters have extended warranties from 20 to 25 years. Solar water heating systems have 10 year warranties.

Why is solar power good for the environment?
Sun-generated power is clean — no pollution, noise-free and reduces your dependence on finite resources. A typical 3 kilowatt solar electric system will eliminate 101 tons of CO2 over its 25+ year lifetime. The average residential solar water heating system eliminates 125,000 pounds of CO2 over its lifetime. If homeowners make the switch to providing their own energy, the benefits will become apparent in our neighborhoods, our state and the globe.
What is Net Metering?
This program allows utility customers that have solar electric systems to “turn their utility meter” backwards when they generate electricity in excess of their demand. This offset means that customers receive a credit on their monthly bill for the excess electricity they generate.
Why is it smart to finance solar?
You already pay a monthly utility bill for energy, essentially financing an indefinite, variable rate loan from your utility company. Installing a solar power system allows you to refinance this monthly bill at a fixed rate and term and have your payments go towards ownership of a valuable asset.
