How it works

The calculator multiplies your system size by the estimated annual production per kilowatt for your location to get total annual output in kWh, then values that output at your electricity rate to estimate annual savings.

Payback period is your total install cost divided by annual savings. 25-year net savings projects that same annual savings forward and subtracts the upfront cost — it does not account for panel degradation, rate changes, or maintenance.

The production estimate above reflects solar resource data for Kentucky. Actual output depends on roof angle, shading, panel efficiency, and local weather patterns.

Solar potential in Kentucky

As of June 2026, a solar system in Kentucky can be expected to produce roughly 1,092 kWh per kilowatt of installed capacity each year, based on solar resource data from NREL. Use the calculator above to estimate payback period and long-term savings for a specific system size and cost.
