  • Celena

    Untrustworthy, predatory, unprofessional scammers, don't trust the reviews which are obviously put here by their employees. They have preyed on the elderly in West TX including my 80 year old parents who were duped into signing a lien that will exist long after they are no longer alive. Mosaic's web…

  • Leah H.

    Terrible, frustrating, unprofessional, do not use. The worst company I have ever encountered was the solar company who connected me with Mosaic. They had the decency of going out of business. Mosaic now holds that space. This company (Mosaic) knowingly partnered with contractors who quickly locked c…

How this Oakland 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 panels can significantly reduce bills. Selling power back earns less, so using solar power at home is more valuable.
How many solar panels do I need for my home?
Panel needs depend on your energy use and roof. South-facing roofs need fewer panels; east or west require 15% more. Heavy shade reduces output.
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, making home usage more beneficial.
Are there solar tax credits available in 2026?
The 30% federal tax credit ended for purchases after 2025, but leases and PPAs may still carry a credit through 2027.
How does roof direction affect solar panel efficiency?
South-facing roofs are optimal. East or west-facing roofs need about 15% more panels, while north-facing roofs are usually not recommended.
How much electricity does an electric car add to my home use?
Charging an electric car at home adds roughly 2,700 kWh annually, equivalent to about 15,000 km of driving.
How accurate is the solar panel cost calculator?
The calculator estimates system size and cost based on your inputs like bill, roof, and goals. It's a general guide, not a precise quote.
