How this San Francisco 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 about 33.3 cents per kWh, solar can reduce bills. Using power at home is more valuable than selling it back to the grid.
How many solar panels do I need for my home?
Panel count depends on your energy use, roof direction, and shade. A typical 6 kW system might need about 20 panels.
What is the payback period for solar panels in California?
Payback depends on energy use and savings. With high electricity prices, many systems pay back within 7-10 years, but this varies.
Can I sell power back to the grid in California?
Yes, but under NEM 3.0, exported power earns only a few cents per kWh, so using solar power at home is more beneficial.
Are there any solar tax credits available in 2026?
The 30% federal tax credit ended for purchases after 2025. Leases and PPAs may still offer credits through the installer until 2027.
How does roof direction affect solar panel efficiency?
South-facing roofs are best. East or west roofs need about 15% more panels. North-facing roofs are usually not viable.
Do electric cars affect my solar panel needs?
Yes, each electric car adds about 2,700 kWh a year to your electricity use, potentially requiring more panels.
