- A typical Louisville home can save around $35,000 over 25 years with solar, with leasing options starting as low as $81/month and no upfront cost.
- LG&E customers in Louisville have access to net metering, meaning excess solar energy you generate earns credits toward your electricity bill.
Louisville Electricity Prices
Electricity rates in Louisville, KY are rising — and understanding that trend can help you make smarter energy decisions for your home.
Kentucky’s electricity rate climbed from 11.5 cents per kWh in 2021 to 13.0 cents per kWh in 2024 — a roughly 13% increase. While Louisville rates remain below the national average of 16.5 cents per kWh, the upward trend is clear.
Solar can help offset that rising cost. By generating your own electricity, Louisville homeowners can reduce how much power they pull from the grid — which means less exposure to future rate increases.
Solar panels typically last 25 years or more. Over that time, locking in a portion of your energy supply at a fixed cost can provide real, long-term protection against unpredictable utility rate changes.
Price of Energy: Kentucky vs National Average
Louisville Area Utility Providers
Louisville homeowners are served by LG&E (Louisville Gas and Electric). Based on 2023 data — the most recent available — LG&E’s residential electricity rate was 12.4¢ per kWh.
LG&E’s 2023 rate of 12.4¢/kWh sits just below Kentucky’s state average of 12.70¢/kWh and well below the national average of 16.0¢/kWh. LG&E’s energy mix, which includes coal and natural gas, helps keep rates relatively low.
Even with rates below the national average, electricity costs can rise over time. Solar can offer Louisville homeowners a greater degree of long-term cost predictability, regardless of where utility rates trend.

Kentucky Solar Incentives
Louisville homeowners have access to several solar incentives in Kentucky that can help reduce the cost of going solar, depending on your utility provider.
LG&E customers in Louisville may benefit from net metering and community solar through the Solar Share Program. Duke Energy Kentucky’s PowerPair rebate — up to $9,000 for solar plus battery storage — applies to Duke Energy service areas, not LG&E territory.
Recent federal tax policy changes have eliminated the residential solar tax credit. State and local programs still exist. With solar leasing, companies like Palmetto handle commercial incentives and pass savings to customers through lower monthly payments.
| Incentive | Type | Description | Source |
|---|---|---|---|
| Kentucky Net Metering (LG&E, KU, and Other Utilities) | Net Metering | Kentucky requires investor-owned utilities and most electric cooperatives to offer net metering for solar systems up to 45 kW, with credit rates varying by utility. | Learn More |
| LG&E and KU Solar Share Program (Community Solar) | Rebate | LG&E and KU customers can subscribe to shares of a community solar project and receive monthly bill credits without installing panels on their own property. | Learn More |
Kentucky state law (S.B. 100) requires all investor-owned utilities and electric cooperatives — excluding TVA-served utilities — to offer net metering for qualifying solar systems up to 45 kW. The credit structure is set by the Kentucky Public Service Commission (PSC) on a utility-by-utility basis. LG&E and KU Energy — the primary utility providers serving Louisville — offer full retail net metering, meaning every excess kWh you send to the grid earns a credit at the same rate you pay for electricity — giving you 100% of the value of your surplus solar energy. Customers who enrolled with LG&E or KU before September 24, 2021, may be grandfathered under older credit structures.
Homeowners in Louisville should contact their specific utility provider to confirm current net metering terms and compensation rates.
The LG&E and KU Solar Share Program is a community solar option that allows residential, business, and industrial customers to benefit from solar energy without installing panels on their own property. Customers purchase shares of a local community solar project for less than 20 cents per day and receive corresponding credits on their monthly electricity bill based on the energy their shares produce.
This program is ideal for renters, homeowners with shaded or structurally unsuitable roofs, or anyone who wants to participate in solar energy without the upfront installation costs or long-term maintenance responsibilities of a private system. Solar Share credits can even be gifted to a friend, family member, or organization of your choice, making it a flexible and accessible way to go solar in Louisville.
The Solar Share Program is administered by LG&E and KU Energy and is available to customers within their service territories. There is no installation required, no long-term maintenance commitment, and participation can begin with a minimal financial commitment. Contact LG&E/KU or visit their website to check current share availability and pricing.

Leasing Solar Panels
If paying the full cost of a solar system upfront isn’t the right fit for you, Palmetto offers a solar lease through LightReach — available to homeowners in Kentucky, including Louisville. With a lease, you pay a fixed monthly amount (for example, $81/month for a medium-sized home) rather than a large upfront investment. Palmetto owns and maintains the system, so you’re never responsible for repairs or performance issues.
Compared to a cash purchase, leasing means no out-of-pocket installation costs, no maintenance responsibilities, and predictable monthly payments from day one. When you own a system outright, you’re also responsible for any repairs, monitoring, and long-term upkeep — costs and effort that can add up over a 25-year system lifespan. With LightReach, Palmetto handles all of that for you, and the system comes with a 90% production guarantee.
It’s worth knowing the difference between a lease and a Power Purchase Agreement (PPA): a lease charges a fixed monthly payment, while a PPA charges you per kilowatt-hour of electricity your panels produce — meaning your bill may vary by season. In Kentucky, Palmetto currently offers the solar lease option. To learn more about how these two options compare, visit our solar buy or lease guide.
Go solar without the investment
With LightReach, there are no investment costs to recoup, loan payments to manage, or maintenance needs to take on. As soon as your panels are active, your solar savings are too!

Yes, solar makes sense for many Louisville homeowners. Kentucky electricity rates have risen 13% since 2021, and a typical Louisville home can save around $35,000 over 25 years with solar. LG&E customers also benefit from net metering, earning bill credits for excess energy sent to the grid.
If upfront cost is a concern, Palmetto’s LightReach solar lease removes that barrier entirely — Louisville homeowners can go solar with no money down and start saving from day one, with payments starting as low as $81/month.
Yes, Louisville homeowners served by LG&E have access to net metering. Kentucky state law requires investor-owned utilities, including LG&E, to offer net metering for solar systems up to 45 kW.

It’s worth noting that this benefit typically applies to owned systems, not leased ones. If you purchase your solar system outright, the added value generally transfers to the home. With a lease, the panels are owned by the solar company, which may affect how buyers and appraisers view the system.
