Benefits of Solar Energy

Solar energy provides numerous advantages that will enhance your home for years to come.

  • Reduced carbon footprint: Adopting solar is a surefire way to minimize your carbon footprint and home fossil fuel dependency.
  • Lowered energy bills: With solar panels, you produce power without paying the tacked-on costs of grid-tied power. You can eliminate your bills completely if you go off-grid. Plus, a significant number of states offer net metering, which permit you to earn money by selling your unused energy back to the grid.
  • Better energy independence: Solar panel systems with energy storage systems work through blackouts and emergencies, and you won't have to depend on the electrical grid for your safety and well-being.

What Solar Incentives Are Available to Louisville Homeowners?

The state of Kentucky offers a variety of solar incentives to help reduce your solar system costs. Here's a breakdown of relevant solar programs where you live.

Incentive Amount:

30% federal tax credit for systems placed in service after 12/31/2021 and before 01/01/2033. Good for: solar water heat, solar photovoltaics, biomass, geothermal heat pumps, wind (small), fuel cells using renewable fuels.

How To Choose the Best Solar Company in Louisville

The cost and performance of solar panels often rely on the solar company that installed them. Here are some crucial criteria to bear in mind while searching for a solar provider.

Licensing and Training

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 on the team to retain building permits and connect the system to meters and utility grids. You should also visit a company's website to learn about its private accreditations. Two of the most prestigious are the Solar Heating Installer and PV Installation Professional certificates, awarded by the North American Board of Certified Energy Practitioners (NABCEP). Some companies don't publish this information online, so you should also ask your estimator about them.

Cost of Solar Panels in Louisville

Different solar panel types look and perform differently. Monocrystalline panels offer the best energy production but cost more than other options and generally have the highest quality. Polycrystalline panels provide a lower price point but produce less power. Thin-film panels work well for small projects like RVs and sheds, but they're not ideal for larger installations due to their low performance.

Additional accessories, such as battery storage and electric vehicle (EV) chargers, will add to your overall installation costs. However, they might make your solar system more efficient and convenient to use. Not every solar company offers these add-ons, so look for a provider that installs them if it's crucial for you.

A majority of Louisville homeowners choose solar systems rated for five kilowatts (kW) of electrical capacity. These systems run about $18,250 to set up, considering both parts and installation. You can find more specific solar cost information in the table.

Solar Panel CostAverage Cost
Solar Monocrystalline$1,147
Solar Polycrystalline$894
Thin-Film$523
Solar Battery$734
Solar Home EV Charger$2,752

Financing Solar Energy in Louisville

Solar installers use multiple different financing options to lower your costs and increase your savings. Though some providers offer unique payment plans, the most common are solar loans, power purchase agreements (PPAs), cash payments and solar leases. Though it involves a large up-front payment, cash is the most affordable choice because it qualifies you for solar incentives and doesn't accrue interest. Solar loans are the runner-up option. As with a home or auto loan, you'll pay a monthly rate towards system ownership, including interest. You can still apply for valuable solar incentives, and depending on your lender, you could put as little as $0 down. Solar leases involve paying a set monthly rate to use rooftop panels. A PPA (Power Purchase Agreement) allows you to pay a monthly rate determined by the energy you use, like an electric bill. We usually don’t recommend these two choices because you won't own the panels and cannot use solar incentives. We advise working with a contractor that offers multiple financing options. Talk to each agent about what's available, and get more than one estimate for the best odds of staying within your budget.

The table below lists the average payback periods for different capacities of solar systems in Louisville.

The IRS allows you to claim a 26% federal tax credit for solar panels on your new solar panels, so long as you purchase it before 2032. Local governments and utilities might also offer their own financing programs, incentives, and rebates that could save you more money.

Solar System CapacityEstimated Payback period
1 kW2.3 years
2 kW4.6 years
5 kW11.4 years
10 kW22.9 years
