How To Choose a Solar Company

Installing solar panels can reduce your electricity costs and benefit the planet by reducing your carbon footprint. When determining whether a solar provider is the best option for you, consider these key factors.

Check Licensing

Hiring a licensed solar installer is critical. This helps ensure that the work is done correctly using current installation best practices. 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 the Better Business Bureau (BBB), TrustPilot, Google Reviews, and other review sites to see what past customers have to say about local solar installers. Detailed reviews on these platforms can help you assess a provider's integrity and customer service. Avoid providers with few or mainly poor reviews.

Compare Multiple Quotes

Contact at least three solar companies for free, detailed quotes. Quotes should clearly outline all costs and list the exact solar components included. By comparing multiple quotes, you can identify the most cost-effective option for you.

Ask About the Warranty

Quality solar installations should have strong workmanship and performance guarantees. A workmanship guarantee covers any installation defects (such as poor wiring, cracks in the panels, or poor alignment), while a performance guarantee ensures a certain level of energy production. Strong warranties show that a company is confident in its work.

Evaluate Financing and Incentives

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

  • Compare system purchase options: Solar panels can be purchased upfront or financed over time with a lease or loan. Verify key financing details like payment schedule, annual percentage rate (APR), fees, and ownership implications when choosing to finance solar panels.
  • Look into utility rebates: Local utility companies may offer additional rebates to encourage homeowners to adopt solar panels. Check the eligibility rules and rebate values with your local electric company to find out what your savings could be.
  • 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 result in significant savings for solar buyers.
