Estimate what solar does against your Duke Energy Ohio bill
Enter your bill and we’ll size the array that would cover it, and show the gross value of that production at your rate. It does not net off the customer charge, taxes or what you would still draw at night — for that, use the bill savings calculator. Nothing is sent anywhere; this runs in your browser.
An estimate from your own numbers, not a quote, and not a savings figure. It assumes 400 W panels, an 80% system derate and no roof constraints. Your real number depends on orientation, roof area and your utility’s export credit. Savings are not guaranteed.

Why the number is what it is
What is actually driving this
PJM capacity costs
Duke Energy Ohio buys standard-offer generation through PJM. The June 2026 reset carried the higher capacity price into the price to compare.
A pending distribution case
Duke’s 26-0132-EL-AIR filing would raise a typical residential bill about $8.32 a month from 2027. The Ohio Consumers’ Counsel is contesting it.
Monthly resets
Duke posts a new price to compare every month, so the supply line on your bill changes twelve times a year rather than four.
The honest cost picture
Two ways to pay for solar, and they are very different
If you buy the system
You own the equipment, you keep any renewable energy credits, and you carry the maintenance responsibility. Installed pricing varies by roof, shading and system size.
If you use a PPA
$0 upfront. We install and own the system; you buy the power it produces at a rate set in your agreement, and you only pay for what it actually generates. The system owner carries maintenance for the life of the agreement.
The residential federal tax credit (25D) ended for property placed in service after December 31, 2025.
You will still see ads promising a 30% credit that “ends December 31.” Read the date on them. If you buy a system today as a homeowner, you cannot claim that credit. What remains applies to the owner of the system — which, under a PPA, is us. SolarAmerica does not provide tax advice; talk to your tax professional about your situation.
