How To Choose a Solar Company

Going solar can be a great way to save money on electricity costs and help the planet by reducing your carbon footprint using renewable energy. Here are some crucial factors to consider when determining whether a solar installer is trustworthy.

Check Licensing

It's imperative that your solar installer has the proper licensing. This ensures that the work is done properly using current best installation 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

Check the Better Business Bureau (BBB), Google Reviews, TrustPilot, and other review sites to see what past customers have to say about local solar installers. Detailed reviews can help you evaluate a provider's reliability and customer service. Avoid companies with few or mainly poor reviews.

Compare Multiple Quotes

To find a solar company that fits your budget, ask for free, detailed quotes from at least three providers. The quotes should list all costs as well as all solar equipment included. Looking at several quotes helps you identify the option that best fits your budget.

Ask About the Warranty

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

Evaluate Financing and Incentives

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

  • Look into utility rebates: More rebates might be available from local power companies looking to encourage homeowners to go solar. Contact your local utility provider to learn rebate values and qualification criteria, so you can determine your possible savings.
  • Research federal and state tax credits: A 26% federal tax credit on total solar system costs is available through 2032. Many states provide incentives, too. The credits can result in substantial savings for solar buyers.
  • Compare system purchase options: Solar panels can be purchased outright or financed over time through loans or leases. Confirm all terms when financing, including payment schedule, annual percentage rate (APR), fees, and ownership implications.
