The requirement covers investor-owned utilities
Kansas has two investor-owned utilities, Evergy and the Empire District Electric Company, and both are required to offer net metering. That is where the familiar Kansas arrangement comes from.
Municipal utilities and rural electric cooperatives are governed differently. They set their own rates and their own rules for customer generation.
That can cut either way. A cooperative or municipal utility may compensate exports more generously than the investor-owned arrangement or less, may cap system sizes differently, and may charge different interconnection fees.
It also means a solar-specific charge is not necessarily off the table, since the 2020 Kansas Supreme Court decision concerned Evergy rather than every utility in the state.
The questions for your own utility
Ask how exported electricity is compensated and at what rate, and whether generation is netted across a billing period or on a shorter interval.
Ask whether credits carry forward, whether they expire and on what date, since an annual expiry changes how a system should be sized and the absence of one changes it back.
Ask what system size limits apply, whether a relative rule like the 150 percent of consumption test is used, and what the interconnection application involves and costs.
Ask explicitly whether any solar-specific charge, demand charge or minimum bill applies to customer generators. Get the answers in writing from the utility.
Reconciling the quote with the answers
Ask which arrangement the projection assumed and which retail rate it applied, then check both against what the utility told you and against a recent bill.
Ask what self-consumption share the model assumed. If your utility nets on a shorter interval than a full month, that assumption drives the savings figure far more.
Ask whether the installer has completed projects on your specific utility recently. Interconnection practice varies and recent local experience is what moves a project along.
If the quote cannot be reconciled with what the utility told you, ask for it to be rebuilt rather than explained.
What belongs in the projection, and what does not
The 30 percent federal Residential Clean Energy Credit under Section 25D expired for property placed in service after December 31, 2025, so a cash or loan purchase receives no federal tax credit, and Kansas has no state solar tax credit.
Section 48E survives at 30 percent for third-party owners under leases and power purchase agreements, so ask what a provider claims and what reaches you in the rate.
Everything else comes from your own utility: the retail rate, export compensation, the netting interval, credit expiry, size limits, interconnection and any solar-specific charge.
Ask for the projection rebuilt from those answers, with your rate taken from a recent bill.
