How this Irvine 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

8 questions
How many solar panels do I need for my home?
A typical 6 kW system needs about 15-20 panels, depending on panel wattage and roof orientation. South-facing roofs need fewer panels.
Are solar panels worth it in California?
With electricity at 33.3 cents/kWh, solar can reduce bills significantly. However, payback depends on usage, roof direction, and shade.
What is the payback period for solar panels in Irvine?
Payback varies based on system cost, energy use, and incentives. Generally, it takes several years to recoup costs through savings.
Can I sell excess solar power back to the grid in California?
Yes, but under NEM 3.0, exported power earns only a few cents per kWh. Using solar power at home is more valuable.
What rebates or tax credits are available for solar in 2026?
The 30% federal tax credit ended for purchases after 2025. Leases and PPAs may still qualify for a federal credit through 2027.
How does roof direction affect solar panel efficiency?
South-facing roofs are optimal, needing fewer panels. East or west roofs need about 15% more panels; north-facing roofs are usually not recommended.
How does charging an electric car at home affect solar needs?
Each electric car adds about 2,700 kWh/year to electricity use, increasing the size of the solar system needed.
How accurate is the solar panel cost estimate?
The estimate considers power bills, home size, roof orientation, and shading. It provides a general idea but isn't a precise quote.
