  • Jim

    I can’t even begin to describe what a disaster this company and their people are. It’s been a year since our solar installation and we are still not generating power. We are paying for a system that doesn’t work even remotely close to what was promised. They keep making mistake after mistake and we…

    I started out loving this company but have had nothing but issues from the beginning. From driving over wiring and installing bent panels to electrical issues that took awhile to get fixed. My electric bills have skyrocketed and their system is down. The sales rep no longer responds and no one will…

How this Riverside solar cost calculator works

This calculator sizes a solar system from your electricity use. Your monthly bill, divided by the average California electricity price, gives your yearly use; California's sunshine (1,677 kWh per kW of panels a year) then gives the system size that covers it, adjusted for roof direction and shade. The installed price is that size multiplied by the price per watt homeowners in California pay installers. Payback compares that price with what the panels save at California power prices, assuming prices rise 3% a year.

California numbers this calculator uses

Installed price
$2.14–$2.90 per watt in California (typical $2.52), before rebates. A typical 6 kW home system costs $12,800–$17,400.
Sunshine
1,677 kWh of electricity per kW of panels a year in California.
Electricity price
About 33.3¢ per kWh, the average residential price in California.
Selling power back
Power you send to the grid earns less than the price you pay for it (net billing or avoided-cost credits), so using your solar power at home is worth more.
Rebates and tax credits
California's net billing (NEM 3.0) pays only a few cents for exported power, so many installers pair panels with a battery. The 30% federal tax credit for buying solar ended for systems installed after December 31, 2025. Leases and power purchase agreements can still carry a federal credit through the installer for systems in service by the end of 2027.

An estimate, not a quote. Roof size and pitch, shading, equipment, permits and the installer all change the final price; installers confirm it after a site visit. Sources: EnergySage state installed-cost data (2026), NREL PVWatts, U.S. Energy Information Administration residential prices (2026), state program pages.

Frequently asked questions

7 questions
Are solar panels worth it in California?
With electricity at 33.3 cents per kWh, solar panels can reduce bills significantly. Using solar power at home is more valuable than selling it back.
How many solar panels do I need for my home?
The number of panels depends on your energy use, roof direction, and shading. A typical 6 kW system might need about 18 panels.
What is the payback period for solar panels in Riverside?
The payback period varies based on energy savings and system cost. Generally, it can take several years to recoup the investment.
How does roof direction affect solar panel efficiency?
South-facing roofs are most efficient. East or west roofs need about 15% more panels. North-facing roofs are usually not recommended.
Can I sell excess solar power back to the grid in California?
Yes, but NEM 3.0 pays only a few cents for exported power, making home use more valuable.
Are there any solar tax credits available in 2026?
The 30% federal tax credit ended for systems installed after 2025. Leases and PPAs may still carry credits through 2027.
How does having an electric car affect my solar needs?
Each electric car charged at home adds about 2,700 kWh a year to your electricity use, impacting solar system size.
