How To Choose a Solar Company

Putting solar panels on your roof could lower your electricity payments while benefiting the planet by reducing your carbon footprint through renewable energy use. Key considerations when looking at local solar installers are as follows.

Check Licensing

Confirm that your solar installer is properly licensed. 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, the Better Business Bureau (BBB), and TrustPilot to see feedback from past customers on local solar companies. Detailed reviews can help you assess a company's dependability and customer service. Use caution with companies that have no reviews or mostly negative ones.

Compare Multiple Quotes

To find a solar company that works with your budget, get 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 best value.

Ask About the Warranty

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

Evaluate Financing and Incentives

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

  • Look into utility rebates: Some energy providers may provide additional rebates to encourage homeowners to adopt solar power. Check the requirements and the rebate amounts offered by your local electric utility to estimate the 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 may be paid for outright or financed through loans or leases. Confirm important financing details such as payment schedule, fees, annual percentage rate (APR), and ownership implications when financing your solar system.

Solar panel costs vary based on your system's capacity and the technology being used. The average solar system in Union has a capacity of 7.2 kilowatts.
