How this San Diego 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, though payback varies by usage and incentives.
How many solar panels do I need?
System size depends on goals and roof conditions. Each kW generates about 1,677 kWh annually in California.
What is the payback time for solar in San Diego?
Payback depends on system cost, usage, and incentives. Without the 30% federal credit, expect longer payback times.
Can I sell power back to the grid in California?
Yes, but NEM 3.0 pays only a few cents for exported power, making home usage more valuable.
Are there solar rebates in California for 2026?
The 30% federal tax credit ended for systems installed after 2025. Leases may still offer credits through 2027.
How does roof direction affect solar panel efficiency?
South-facing roofs are best, needing fewer panels. East or west roofs need about 15% more, while north-facing roofs are less effective.
How does charging an electric car at home affect solar needs?
Each electric car adds about 2,700 kWh annually to electricity use, influencing the size of the solar system needed.
