Most homeowners save $27,000 to $110,000 over 25 years by switching to solar. But what you’ll actually pocket depends on where you live, your electricity rates, and available incentives. Here’s exactly how to calculate your potential savings.
The Real Question: Is Solar Worth It for Your Home?
Rising electricity bills have homeowners searching for solutions. Solar seems like the answer, but you need to know the real numbers before committing. We’ll break down costs, savings, and payback periods across different states so you can make a confident decision.
Key Numbers: What Solar Actually Costs (and Saves)
An average 12 kW solar system costs around $29,649 before incentives in 2025. But here’s the good news: the federal tax credit covers 30% of that cost, bringing it down to roughly $20,755.
After incentives and state rebates, actual costs vary dramatically by location:
- Low-end states (like Arizona, Texas): $15,000–$20,000
- Mid-range states (like Colorado, Maryland): $18,000–$25,000
- High-cost states (like Massachusetts, New York): $20,000–$30,000
Most homeowners break even in 7–10 years, then enjoy 15–20 years of nearly free electricity.
Where You’ll Save the Most: Top Performing States
States with the Fastest Payback (5–7 Years)
Nevada, Hawaii, Arizona, New Jersey
These states combine high electricity rates, abundant sunshine, and strong incentive programs. A Nevada homeowner might see their $120 monthly bill drop to $20—with additional earnings from net metering credits.
States with Strong Long-Term Savings ($80,000+)
California ($78,500), Massachusetts ($86,500), New York ($88,500), Connecticut ($119,000)
High electricity costs mean massive cumulative savings, even if payback takes 8–10 years.
Budget-Friendly Solar States
Texas, Florida, North Carolina, Colorado
Lower upfront costs and strong sunlight hours deliver solid 10-year payback periods without breaking the bank.
The Cost Breakdown: Where Your Money Goes

How to Maximize Your Savings in 2025
Claim the 30% federal tax credit. This isn’t a rebate, it’s a direct reduction of your tax liability. Virtually every homeowner qualifies.
Check for state and local incentives. Some states offer additional rebates, tax credits, or net metering (selling excess power back to the grid for credits). DSIRE USA is a free database of all available programs in your area.
Look for battery storage options. In states with high “peak hour” electricity rates, a battery can store daytime solar power for use during expensive evening hours, boosting your savings by 30–50%.
Compare multiple quotes. System costs vary by installer. Getting 3–5 quotes can save you thousands, installers often compete on price and service.
FAQs: Your Solar Questions Answered
Q: Will solar work if I live in a cloudy state?
A: Yes. Even cloudy states like Massachusetts and New York see strong returns thanks to high electricity rates and state incentives. Panels generate power on overcast days, just at reduced capacity.
Q: What if I don’t have a good roof?
A: Roof condition matters. If your roof needs replacement, do that first (typically $8,000–$15,000). Solar installers can assess your roof and recommend repairs if needed.
Q: Can I get solar with no money down?
A: Absolutely. Solar loans and leases let you go solar with $0 upfront. You’ll start saving immediately on your electricity bill.
Q: How long do solar panels last?
A: Most panels last 25–30 years and maintain 80% efficiency after that. Quality panels come with 25-year warranties.
Q: What if I sell my house?
A: Owned solar systems increase home value by roughly the amount you’ve saved on electricity. Leased systems transfer to the new owner, check your lease agreement.
Q: Are there any hidden costs?
A: Minimal. Maintenance is nearly zero. You might pay for tree trimming ($300–$1,500) if shade develops over time.
