Wind rating and attachment detail
A solar array is a wind load on your roof for the whole life of the system, and in central Oklahoma that load is a serious design input rather than a formality.
Ask what wind speed the racking and attachment system is rated and engineered for, and how that compares to the local building code requirement for your address.
Ask how the array attaches to the structure, how many attachment points there are, and whether the installer performed or commissioned a structural assessment of the roof.
Ask what the warranty says about wind damage specifically, and how it interacts with your homeowner insurance. A general product warranty and a wind provision are not the same thing.
Insurance, before rather than after
Call your insurer before installation, tell them the system size and cost, and ask in writing whether the array is covered under your dwelling coverage or requires a separate endorsement.
Ask whether your wind and hail deductible differs from your standard deductible. In storm-prone states it frequently does, and that difference is the number that matters after an event.
Ask whether adding the system changes your premium, and by how much. That is a recurring cost and it belongs in the payback arithmetic rather than being discovered at renewal.
Keep the installation documentation, including equipment models and the structural assessment. After a storm that paperwork is what makes a claim straightforward.
What solar does in an outage, which is nothing
A standard grid-tied inverter disconnects when the grid goes down, for the safety of line workers. So an array without a battery is inert during exactly the event you most wanted it for.
Backup requires a battery plus an inverter and switching arrangement designed for it, specified in the quote as equipment rather than implied.
Ask which circuits would be backed up and for how long under a realistic load, and say explicitly whether air conditioning needs to be on that list. In an Oklahoma summer outage that is not a small question.
There is a modest everyday economic case too, since a battery keeps generation inside your own consumption rather than letting it become surplus credited at avoided cost. But resilience is the honest headline here.
Building the number without the federal credit
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 on the panels or the battery, and Oklahoma 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 retail-rate offsetting within the billing period, avoided cost for surplus, and the electricity you stop buying at around 13.4 cents per kWh.
Add any insurance premium change as a recurring cost, and price the resilience benefit as something you are choosing to buy rather than folding it into a savings figure.
