How many quotes should I get in Costa Mesa?

Get at least three written quotes from licensed, insured California contractors. Comparing line items — not just the bottom line — is the fastest way to spot an inflated bid in the Orange County market.

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.
