How to Choose a Solar Contractor: Questions Homeowners Should Ask

Quick Answer
Choosing a solar contractor involves verifying licensing and insurance, reviewing references and prior work, comparing detailed proposals, understanding warranties and workmanship terms, and asking how post-install issues are handled. Get more than one quote and put assumptions in writing.
Key Takeaways
  • Verify licensing, insurance, and electrical permitting in your area.
  • Ask about experience with your roof type and system size.
  • Read workmanship warranty terms separately from equipment warranties.
  • Ask how monitoring, service calls, and warranty claims are handled.
  • Compare proposals side by side — equipment, production, financing, scope.

What to verify upfront

Confirm contractor licensing and insurance for your state. Ask how many similar installations they have completed and request references or examples. Confirm who pulls permits, who handles utility interconnection, and what inspections are involved.

What to compare in the proposal

Equipment brands and tiers, production estimate with assumptions, included permits and interconnection, monitoring, warranty terms (panel, inverter, battery, and workmanship), financing structure, and exclusions. Side-by-side comparison helps.

After installation

Ask how the contractor handles service calls and warranty work, how monitoring alerts are tracked, and what the workmanship warranty covers and for how long. Clear answers here matter as much as the install itself.

Frequently asked questions

Should I pick the cheapest quote?

Not by default. Look at equipment, warranties, and workmanship. Lower price sometimes means smaller system or lower-tier equipment.

Does HSRC vet contractors?

HSRC connects homeowners with independent local providers. We do not represent that we vet, certify, or rank contractors unless that is explicitly stated.

What red flags should I watch for?

Pressure to sign immediately, missing license information, vague assumptions, equipment swaps after signing, and unclear warranty terms.

Is more than one quote required?

Not required, but comparing several quotes typically gives a clearer picture of fair pricing and design choices.
