How To Choose a Solar Company

Adopting solar power lets homeowners lower utility bills while benefiting the planet by reducing your carbon footprint using clean energy. If you’re evaluating if you want to go solar, consider these key factors for choosing an installer.

Check Licensing

It's imperative that your solar installer has the proper licensing. This ensures that the work is done correctly using the most up-to-date installation methods. In Missouri, cities and counties have the right to issue contracting licenses. However, all contractors must register with the Missouri Secretary of State.

Read Customer Reviews

Check review sites like Google Reviews, the Better Business Bureau (BBB), and TrustPilot to see customer feedback about local solar companies. Detailed reviews can help you evaluate a company's reliability and customer service. Use caution with companies that have no reviews or mostly negative ones.

Compare Multiple Quotes

Call at least three solar companies for free, itemized quotes. These quotes should outline all costs and specify the solar equipment included. Reviewing multiple quotes helps you find the option that aligns with your budget.

Ask About the Warranty

Quality solar installations should come with comprehensive workmanship and performance guarantees. The workmanship warranty covers any installation problems such as poor wiring, poor alignment, or cracks in the panels. The performance guarantee ensures a specific energy output level. Strong warranties indicate that a solar installer has faith in its installations.

Evaluate Financing and Incentives

Solar panels can help decrease your electricity costs long-term. When weighing solar panel's cost and value, be sure to consider these considerations.

  • Research federal and state tax credits: There’s a 26% federal tax credit available for total solar system costs until 2032. Many states also offer incentives. The credits can add up to significant savings for solar buyers.
  • Compare system purchase options: Solar panels may be paid for upfront or financed over time through leases or loans. Verify all terms when financing, including payment schedule, fees, annual percentage rate (APR), and ownership implications.
  • Look into utility rebates: Local power companies may offer additional rebates to encourage homeowners to adopt solar panels. Check the qualification criteria and rebate values with your local utility provider to find out what your savings could be.
