Question 1

How accurate is this solar savings calculator?

Accepted Answer

This calculator uses real EIA electricity rate data and NREL sun-hour averages for each state to produce estimates that are typically within 10–15% of actual installer quotes. Your actual savings depend on your roof angle, shading, local utility rates, and the specific equipment your installer uses. Get 3 free quotes to see real numbers for your home.

Question 2

Is there still a federal solar tax credit in 2026?

Accepted Answer

The 30% federal residential solar tax credit (Section 25D) expired December 31, 2025. Homeowners purchasing a system in 2026 no longer qualify. Solar leases and PPAs are the exception — the installer can claim commercial credits and pass savings through in the monthly rate. State and local incentives now drive the payback math.

Question 3

How long does it take for solar panels to pay for themselves?

Accepted Answer

Without the 30% federal ITC (which expired December 31, 2025), the average payback period in the U.S. is now 9–14 years, depending on your state's electricity rates, available state incentives, and how much sun your area gets. States with high electricity rates and strong state programs — like Connecticut, Massachusetts, and New Jersey — typically see payback periods of 8–11 years. States with lower rates and fewer state incentives may see 12–16 years.

Question 4

What size solar system do I need?

Accepted Answer

A typical U.S. home uses about 900 kWh per month and requires a 6–8 kW system. Your actual system size depends on your energy usage, roof space, and how much of your bill you want to offset. Most installers will design a custom system after reviewing 12 months of your utility bills.

Question 5

Does solar increase my home's value?

Accepted Answer

Yes. Studies by Zillow and Lawrence Berkeley National Laboratory consistently show that solar panels add 3–4% to a home's resale value, with the premium being highest in states with high electricity rates. A $20,000 solar system typically adds $15,000–$20,000 in home value.
