How To Choose a Solar Company

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

Check Licensing

Make sure you hire a licensed solar installer. This ensures that the work is done correctly using the most up-to-date installation methods. Residential solar energy contractors in Kentucky don't have to be licensed electricians or plumbers. However, a plumber or electrician licensed by the Commonwealth must be the one to retain building permits and connect the system to meters and utility grids.

Read Customer Reviews

Check review sites 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 providers that have hardly any reviews or mostly negative ones.

Compare Multiple Quotes

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

Ask About the Warranty

Quality solar installations should have comprehensive workmanship and performance warranties. 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 warranties indicate that a solar installer has faith in its installations.

Evaluate Financing and Incentives

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

  • Look into utility rebates: Local utility companies may offer additional rebates to encourage homeowners to install solar panels. Check the qualification criteria and rebate values with your local utility provider to find out what you could save.
  • Compare system purchase options: Solar panels can be purchased outright or financed over time with loans or leases. Check key financing details like annual percentage rate (APR), fees, payment schedule, and ownership implications when financing solar panels.
  • 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 offer incentives. These credits provide substantial savings for solar customers.
