How this Long Beach 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.

Frequently asked questions

7 questions
Are solar panels worth it in California?
Yes, with California's average electricity price at 33.3 cents per kWh, solar panels can significantly reduce your bill, though payback varies.
How many solar panels do I need for my home?
A typical 6 kW system requires about 15-20 panels, depending on panel wattage and roof conditions.
How is the solar cost estimate calculated?
The calculator estimates cost based on your power bill, home size, roof direction, shade, and energy goals.
Can I sell excess solar power back to the grid in California?
Yes, but California's net billing (NEM 3.0) pays only a few cents for exported power, making home use more valuable.
What rebates or tax credits are available for solar in 2026?
The 30% federal tax credit ended for systems installed after 2025, but leases and PPAs 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 usually not viable.
How does having an electric car affect my solar needs?
Each electric car charged at home adds about 2,700 kWh a year, increasing your solar system size requirement.
