What the statute does and does not do
Nebraska statute at Sections 70-2001 to 70-2004 requires net metering to be offered to customer-generators at up to 25 kW. That is the guarantee.
It does not require net metering above 25 kW, though utilities may allow larger systems at their discretion. For a residential project that limit is unlikely to bind.
And it does not impose a uniform crediting scheme. Net metering and credit rules vary by district across more than 165 entities.
So knowing the statute tells you that you can net meter. It does not tell you what your generation will be worth, which is the number that decides the project.
The questions that fill the gap
Ask how excess generation is credited and at what rate, and whether the credit is denominated in kilowatt hours or in dollars. A kilowatt hour credit holds its value against rate increases; a dollar credit does not.
Ask whether credits carry forward from month to month, whether there is an annual reconciliation, when it falls and what happens to remaining credit at that point.
Ask what the interconnection application involves, what it costs and how long approval typically takes.
Ask whether any solar-specific charge, demand charge or minimum bill applies to customer generators, and get the answers in writing.
Why each of those answers changes the design
If credits are denominated in kilowatt hours, as they are in Delaware, they keep pace with rate rises. If in dollars, they are fixed at the rate when earned.
If there is an annual reconciliation at which unused credit is forfeited, as in Washington, Oregon, Kansas and Montana, the system should be sized to your consumption rather than beyond it.
If there is no such reconciliation, as under the PNM arrangement in New Mexico, a modest annual surplus is less costly and sizing is more forgiving.
So these are not administrative details. They are the inputs that determine what size system is right for your household, and they have to come from your utility.
Costing it out under public power
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 in Lincoln receives no federal tax credit, and Nebraska 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.
What exists is net metering to at least 25 kW under the statutory floor, on terms set by your own utility.
Ask for those terms in writing, then ask for the projection rebuilt on them with your rate taken from a recent bill.
