How much do solar panels cost?

$15,000 to $32,000 for a typical home system before incentives, or about $2.40 to $4.20 per watt installed.

What is the payback period?

Usually seven to twelve years after incentives, faster in high-electricity-cost markets with strong net metering.

How big a system do I need?

Divide your annual kWh usage by about 1,200 to 1,600 depending on sun hours. Most homes land between 6 and 10 kW.

Is the federal tax credit still available?

The residential clean energy credit covers 30% of system cost including batteries. Confirm current-year eligibility with a tax professional before signing.

Only if you want backup power or your utility has poor net metering or time-of-use rates. Batteries add $10,000 to $20,000 and rarely pay back on savings alone.

Should I lease or buy?

Buying captures the tax credit and the full savings. Leases and PPAs mean no upfront cost but much lower lifetime value and friction when you sell the home.

What drives Fullerton pricing

Local labor

Licensed Fullerton contractors carry California workers' comp and prevailing wage pressure, and crews here quote roughly 20% above the national labor average. Demand in the Orange County market peaks in spring, so booking early usually beats a rush premium.

Permits & code

Fullerton follows the California Building Standards Code, so most structural, electrical, plumbing and re-roof work needs a permit from the Fullerton building department plus Title 24 energy compliance. Coastal Orange County projects can require Coastal Commission or HOA design review on top of the city permit.

Climate & conditions

Fullerton sits in a mild coastal climate with strong UV exposure, so expect UV-stable finishes and corrosion-resistant hardware near the coast.
