Hidden Costs to Watch For

Labor can add $3,000–$8,000 on top of equipment costs. Get multiple quotes from different installers to compare.
Roof Reinforcement
If your roof is older than 10 years, you may need a structural assessment. This can add $1,000–$3,000.
Permit Fees
City and county permits run $200–$2,000 depending on your location. Check your local municipality's requirements.
Battery Storage
Adding a home battery (like the Tesla Powerwall) adds $10,000–$15,000. But the 30% credit applies to batteries too.

Frequently Asked Questions
Are there any free solar programs?
"Leasing" or "PPA" programs let you get panels for $0 upfront, but you don't own them and you miss out on the tax credit. Buying is always the better long-term play.
Do solar panels increase home value?
Yes. Studies show solar panels increase home value by an average of 4.1% — a $500,000 home could sell for $20,000 more.
Can I put solar panels on my roof myself?
Technically yes, but it's not recommended. You need electrical expertise, permits, and professional installation to qualify for incentives and warranties.
