Going solar in Kentucky

Kentucky runs on coal power, so adding solar to your home will have a big impact on lowering your carbon footprint. 

The Blue Grass State doesn't offer many solar incentives but its relatively high electricity prices can still make going solar well worth it––especially, if you're lucky to live in an area where net metering is available. 

Here's what you should know about getting solar panels in Kentucky.

Cost

How much do solar panels cost in Kentucky?

Solar panels will save you a lot of money over time, but the upfront costs aren't cheap. The average Kentucky homeowner needs a 14.42 kW solar panel system to cover their electricity needs, which comes out to $41,613 before incentives. Prices range from $35,371 to $47,855, but after the federal tax credit, that drops by 30%. 

While this may sound high, some Kentucky utilities offer a solar buyback program called net metering that accelerates your payback period. That's why over 1,200 Kentucky homeowners have used EnergySage to receive and compare quotes for solar installations. You can expect to earn back your initial solar investment through electricity savings in about 14.69 years, while most systems last at least 25 years. You'll often see this number referenced as your solar payback period.

There are a few ways to finance your solar panel system so you don't have to provide all that money upfront. 

  • Cash purchase: You'll own the system and pay for it upfront. This provides the best long-term savings. 

  • Solar loan: Allows you to retain ownership of your system, while owing little to no money upfront. Solar loans aren't all created equal: If you have access to subsidized clean energy loans through local incentive programs, that's usually your best bet. A home equity loan or a personal loan are often your next best options – private solar loans typically come with higher interest rates or upfront fees.

  • Solar lease or power purchase agreement (PPA): A third-party company owns your system and either leases you the solar panels (solar lease) or allows you to purchase the electricity they generate (PPA). These generally provide the lowest savings and generate the most negative press about solar. If you choose this financing option, read the fine print: You can get trapped in them for longer than you'd like.

Is net metering available in Kentucky?

In some states, you'll earn bill credits from your utility company when your solar panel system generates excess electricity and sends it to the grid. This incentive is known as net metering—basically a solar buyback program—and makes it so you will owe very little, or even nothing, on your electric bills with solar panels. 

Some electric utilities in Kentucky are required by state law to offer net metering to homeowners with solar, while others are not. However, even among the Kentucky utilities that provide net metering, the details vary from company to company.

Equipment

Equipment quality

Each year, solar panels get more and more efficient—that is, they produce more power per square foot. As of 2024, the most popular solar panels can produce about 400 watts of electricity when they’re in full sunlight. If you want to make the most of your roof’s solar potential, get panels with at least that much power output.  

You should also make sure to select a solar inverter setup that makes sense for your roof’s layout. 

And if you want or need a solar battery, be sure to pick one that can integrate cleanly with that inverter. 

Premium equipment can come with a high price tag, but it will often save you more money in the long run. The best equipment tends to have the best warranty terms, often guaranteed to 25 years (sometimes even 40!), so you’re covered in case you need repairs or replacements. The highest-quality panels also degrade more slowly, so they’ll maintain more of their power output further into the future.
