How To Choose a Solar Company

Adopting solar power lets homeowners reduce utility bills while helping the environment by reducing your carbon footprint using clean energy. If you’re deciding whether to go solar, consider these key factors for choosing an installer.

Check Licensing

It's important to hire a licensed solar installer. This help guarantee 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 review sites like Google Reviews, TrustPilot, and the Better Business Bureau (BBB) to see customer feedback about local solar companies. Detailed reviews can help you assess a company's reliability and customer service. Use caution with companies that have barely any reviews or mostly negative ones.

Compare Multiple Quotes

Call at least three solar companies for free, itemized quotes. These quotes should explain all costs and specify the solar equipment included. Reviewing multiple quotes helps you find the most cost-effective option for your budget.

Ask About the Warranty

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

Evaluate Financing and Incentives

Solar energy can help reduce your electric bills over time. When weighing the total price and value of solar panels, be sure to consider these factors.

  • Look into utility rebates: Local power companies may offer additional rebates to encourage homeowners to install 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: A 26% federal tax credit for solar the applies to total system costs is available through 2032. Many states also have incentives. These credits provide substantial savings for solar buyers.
  • Compare system purchase options: Solar panels may be paid for outright or financed over time with a loan or lease. Check key financing details like fees, payment schedule, annual percentage rate (APR), and ownership implications when financing solar panels.
