How To Choose a Solar Company

Putting solar panels on your roof could cut your electricity payments while helping the environment by reducing your carbon footprint through renewable energy use. Key considerations when researching local solar installers are as follows.

Check Licensing

Confirm that your solar installer is properly licensed. This help guarantee that the work is done correctly using current installation best practices. Home solar energy installers in Kentucky don't need to be licensed electricians or plumbers. However, a plumber or electrician licensed by the Commonwealth must be on the team to retain building permits and connect the system to meters and utility grids.

Read Customer Reviews

Check review sites like Google Reviews, TrustPilot, and the Better Business Bureau (BBB) to see feedback from past customers on local solar companies. Detailed reviews can help you evaluate a company's reliability and customer service. Use caution with companies that have barely any reviews or mostly negative ones.

Compare Multiple Quotes

To find a solar installer that works with your budget, ask for free, detailed quotes from at least three providers. The quotes should list all costs as well as all solar equipment included. Comparing several quotes helps you identify the option that best fits your budget.

Ask About the Warranty

Quality solar installations should have strong workmanship and performance warranties. A workmanship warranty addresses any installation defects (such as cracks in the panels, poor wiring, or poor alignment), 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

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

  • Look into utility rebates: Local power companies may offer additional rebates to encourage homeowners to switch to solar power. Check the requirements to qualify and the rebate values with your local power company to determine what your savings could be.
  • Compare system purchase options: Solar panels may be paid for outright or financed over time through a loan or lease. Verify all terms when financing, such as payment schedule, annual percentage rate (APR), fees, and ownership implications.
  • Research federal and state tax credits: There’s a 26% federal tax credit available for the full cost of solar systems until 2032. Many states also provide incentives. The credits can result in significant savings for solar buyers.

Cost of Solar Installation in Louisville

Solar panel costs vary based on system capacity and the solar technology used. The average solar system in Louisville has a capacity of 9.6 kilowatts. Homeowners in the area should expect to pay approximately $3,650 per kilowatt; the average Louisville homeowners spends about $24,524 on a new solar array 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 company will account for factors such as the size, capacity, and panel type of the planned system, and should include prices for labor, permit fees, and preliminary work.
