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 deciding if a solar installer is trustworthy.

Check Licensing

Make sure you hire a licensed solar installer. This helps ensure that the work is done properly 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 consumer review platforms like Google Reviews, the Better Business Bureau (BBB), and TrustPilot to see feedback from past customers about local solar companies. Detailed reviews can help you evaluate a company's dependability and level of service. Use caution with installers that have no reviews or mostly negative ones.

Compare Multiple Quotes

To find a solar installer that works with your budget, get free, detailed quotes from three to five 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

Top-notch solar installations should have strong workmanship and performance warranties. A workmanship warranty covers installation issues, such as cracks in the panels, poor wiring, or poor alignment. A performance guarantee ensures a minimum energy output. Comprehensive guarantees indicate that a solar company believes in its work.

Evaluate Financing and Incentives

Switching to solar power can help decrease your energy expenses. Be sure to consider these aspects when determining the cost and value of solar panels.

  • Look into utility rebates: Local power companies may offer additional rebates to encourage homeowners to switch to solar power. Check the qualification criteria and rebate values with your local power company to find out what your savings could be.
  • Research federal and state tax credits: A 26% federal tax credit on total solar system costs is available through 2032. Many states offer incentives, too. The credits can result in substantial savings for solar buyers.
  • Compare system purchase options: Solar panels can be purchased outright or financed through loans or leases. Check important financing details such as annual percentage rate (APR), fees, payment schedule, and ownership implications when financing your solar system.
