How To Choose a Solar Company

Installing solar panels can cut your electricity costs and benefit the planet by reducing your carbon footprint. When evaluating if a solar provider is a good fit for you, consider these key factors.

Check Licensing

Make sure you hire a licensed solar installer. This helps ensure 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 TrustPilot, the Better Business Bureau (BBB), and Google Reviews 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 very few reviews or mostly negative ones.

Compare Multiple Quotes

Get free, detailed quotes from at least three solar companies. The quotes should describe all costs and identify the solar parts included. Comparing several quotes can help you find the best value for your budget.

Ask About the Warranty

Quality solar installations should include strong workmanship and performance warranties. A workmanship warranty addresses any installation defects (such as poor wiring, poor alignment, or cracks in the panels), while a performance warranty ensures a certain level of energy production. Strong warranties demonstrate a company's confidence in its work.

Evaluate Financing and Incentives

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

  • 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.
  • Look into utility rebates: More discounts might be available from local power companies looking to motivate homeowners to switch to solar power. Contact your local utility provider to learn rebate values and qualification criteria, so you can determine your possible savings.
  • Compare system purchase options: Solar panels can be purchased upfront or financed through leases or loans. Check important financing details such as payment schedule, annual percentage rate (APR), fees, and ownership implications when financing your solar system.

Cost of Solar Installation in Brentwood

Solar panel costs vary based on your system's capacity and the technology used. The typical Brentwood solar array has a capacity of 7.2 kilowatts. Homeowners in the area should expect to pay approximately $3,370 per kilowatt; the average Brentwood homeowners spends roughly $17,060 on a new solar system after accounting for federal tax breaks. (Some homeowners prefer to lease solar panels to reduce their upfront costs.) A personalized quote from a local solar installer will account for factors such as the capacity, panel type, and size of the planned system, and should include prices for preliminary work, labor, and permit fees.
