THE SHORT ANSWER
Start with twelve months of kWh usage, the exact service address and the supplier shown on the bill. Ohio permits net metering, but the current account, tariff and export treatment still need to be verified before a proposal projects savings. [1] [2]
Build the baseline from usage, not the bill total
Collect twelve months of electricity use in kWh and note unusual occupancy, an EV, a pool, electric heat or planned equipment. Dollar totals combine usage, rates and fixed charges; they are not a reliable system-sizing input by themselves. Ask every proposal to state the annual usage figure it used.
Keep the service address, Duke Energy Ohio delivery account and any competitive supplier information together. The proposal should explain which charges solar may affect and which charges are expected to remain.
Show production, self-use and exports separately
Ask for annual production, energy expected to be used at the property while generated and energy expected to be exported. Those are different quantities. Request the assumptions behind each figure and label weather, shade and future-use estimates as estimates.
Cincinnati’s clean-energy guidance describes netting energy delivered to and received from the grid for Duke-served accounts. [1] That overview is a starting point, not a substitute for checking the current account and tariff.
Compare the full installed scope
Put equipment, roof work, electrical work, monitoring, permits, utility submissions, exclusions and payment terms on one page. If a battery is included, ask what operating goal it serves and which loads it supports. Do not treat the battery as proof that every circuit will operate during an outage.
Origin can review the property records and proposal assumptions before confirming availability, design or price for the address.
Keep the remaining bill visible
Ask for a modeled post-solar utility statement alongside the solar payment. Include fixed charges and any supply or export assumptions identified in the current review. A proposal should not describe the utility bill as eliminated or guarantee a future savings result.
Use the same usage baseline when comparing providers. If the numbers differ, resolve the input difference before treating a lower payment as the better offer.
Before your next conversation
- Collect twelve months of kWh usage.
- Confirm Duke Energy Ohio and any competitive supplier.
- Ask for self-use, exports and remaining charges separately.
- Compare equipment, roof, electrical and permit scope.
- Keep every long-term payment term beside the energy assumptions.
Primary sources
- City of Cincinnati: Solar + Clean Energy
Checked October 1, 2026. The city explains Duke Energy net metering at a high level. The current utility tariff and the customer’s supplier arrangement must be verified for the actual account.
- Ohio Administrative Code 4901:1-10-28
Checked October 1, 2026. Ohio’s net-metering rule describes eligible technologies, utility information requirements and potential application, interconnection and meter costs.
