DIY kits exist and cut cost roughly in half, but most utilities require a licensed electrician for interconnection, and self-installed systems can jeopardize roof warranties and some incentive eligibility.
Ways to save
Practical levers that lower the bill without cutting quality.
- Claim the 30% federal credit and stack any state, utility or property-tax incentives.
- Size the system to your actual usage — oversizing rarely pays back where net metering is capped.
- Get at least three quotes; per-watt pricing varies 40% between installers in the same market.
- Cash or a credit-union loan usually beats dealer-financed solar loans with hidden fees.
- Replace an aging roof before installing, not after — removal and reinstall costs $3,000 to $6,000.
Questions to ask your contractor
- 01What is the all-in price per watt before and after incentives?
- 02Which panels and inverters, and what are the separate product and workmanship warranties?
- 03What annual production do you guarantee, and what happens if we fall short?
- 04How does my utility handle net metering, and is that rate locked?
- 05Who handles permits, interconnection and inspection?
- 06How do you flash roof penetrations and what is the leak warranty?
