How much could solar save you?

It depends on your electricity use and system size.

To get a rough idea of how much you could save, take a peek at some estimates for two houses with rooftop solar systems that offset electricity costs by 80% to 90%.

3-bedroom example

The biggest electricity costs of a house this size typically come from running the AC and laundry all the time. Installing a 3.75kW solar system would lower their electric bill significantly.

$153
$31

5-bedroom example

Having both a home office and a swimming pool can leave a household this size with a hefty monthly electric bill. Installing a 4kW solar system would bring down their bill quite a bit.

$325
$65

The way you pay also affects how much you save.

How you choose to pay for getting solar panels and an inverter for your home affects both the initial cost and any ongoing maintenance costs, which can affect your monthly and long-term savings.

Financing through HERO

Financing the purchase of a solar system through the HERO Program, or other lending program, gives you the benefits of owning it without upfront expense. This option offers both financial benefits, as well as costs, but includes valuable consumer protections and typically maximizes your long-term savings.

Other ways to pay

Leasing

Leasing allows you to “rent" the solar system for a set period of time. Generally, you pay a fixed monthly rate no matter how much energy the system produces each month. The solar installer typically maintains the system, but because they also own the system, they get any available tax benefits.

Signing a PPA

With a Power Purchase Agreement, a third party owns and maintains the solar system and you pay for the electricity generated at a rate per kilowatt-hour (kWh) specified in your agreement. As the owner, the third party gets any available tax benefits.

solar panels - water heater
Heat your home's water with solar.
A solar water heating system could cut your water heating bill in half, according to Energy Star.

Combine it with the backup gas-storage water heater, and you could save even more on electricity bills.

Bonus: Qualified solar water heating systems last 20 years on average, which is much longer than the standard gas or electric storage water heaters.

solar panels - pool heater
Warm up your pool for less.
Pool heaters make the water temperature more comfortable and extend the swimming season, but they can be expensive to run. However, installing a solar pool heater can make a warm pool much more affordable.

They're cost competitive with both gas and heat pump pool heaters, but cost less to operate. In fact, solar pool heating is the most cost-effective use of solar energy in California and parts of the Southwest.

Bonus: Your solar pool heater should run smoothly for an average of 10 to 20 years, if the pool's chemical balance and filtering are checked regularly.
