How To Choose a Solar Company

Installing solar panels can lower your electricity costs and help the environment by reducing your carbon footprint. When determining whether a solar provider is a good fit for you, consider these key factors.

Check Licensing

Verify that your solar installer is properly licensed. This helps ensure that the work is done properly using current installation best practices. In Missouri, it's purely up to cities and counties issue contracting licenses. However, all contractors must register with the Missouri Secretary of State.

Read Customer Reviews

Look at review platforms such as TrustPilot, the Better Business Bureau (BBB), and Google Reviews to find out what previous customers say about local solar companies. Reviews can give you an idea of a company’s trustworthiness and customer service. Be wary of companies with no reviews or with predominantly negative feedback.

Compare Multiple Quotes

Call 3–5 solar companies for free, itemized quotes. A quote should explain all costs and specify the solar equipment included. Reviewing multiple quotes helps identify the option that aligns with your budget.

Ask About the Warranty

High-quality solar installations should have robust workmanship and performance warranties. The workmanship warranty covers any installation issues like poor wiring, poor alignment, or cracks in the panels. The output guarantee ensures an energy generation baseline. Strong guarantees reflect a solar provider's faith in its installations.

Evaluate Financing and Incentives

Solar energy can help you lower electricity bills over time. Make sure you consider these aspects when considering the final cost and value of solar panels.

  • Research federal and state tax credits: There’s a 26% federal tax credit available for the full cost of solar systems until 2032. Many states also provide incentives. The credits can result in significant savings for solar buyers.
  • Compare system purchase options: Solar panels can be purchased outright or financed through a lease or loan. Confirm important financing details such as fees, annual percentage rate (APR), payment schedule, and ownership implications when financing your solar system.
  • Look into utility rebates: More discounts might be available from utility companies looking to encourage homeowners to install solar panels. Contact your local utility provider to find out rebate values and eligibility rules, so you can calculate your possible savings.
