Oklahoma Solar Installer Checklist
Questions Oklahoma homeowners should ask before hiring a solar installer: roof fit, utility assumptions, electrical scope, batteries and service support.

Quick answer
The best Oklahoma solar installer is not simply the lowest monthly payment. It is the company that can explain roof risk, utility assumptions, electrical scope, batteries, financing terms and service support in writing before you sign.
Oklahoma homeowners see a wide range of solar pitches: door-to-door promises, national call-center quotes, local installers, roofing-and-solar bundles, battery add-ons and payment-first financing offers. The hard part is not finding a company that will quote panels. The hard part is knowing whether the quote is complete.
This checklist is built for that decision. Use it before you sign with any Oklahoma solar company, including us. A serious installer should be willing to answer these questions without turning the conversation into pressure.
Roof and weather
Roof, hail and attachment questions
Oklahoma solar starts with the roof, not the panel count. A clean proposal should show that the installer looked at age, slope, roof planes, shade and how the array will be flashed into the roof.
Questions to ask
- ✓ Who reviews roof age, decking risk, shingles, shade and future roof replacement timing?
- ✓ What racking and flashing method will be used, and who is responsible if a roof leak appears near an attachment?
- ✓ What happens if hail, wind or insurance work requires panels to be removed later?
- ✓ Will the proposal separate solar work from roofing work if the roof is close to replacement?
Utility and production
Utility, production and bill-model questions
A useful Oklahoma solar quote should show how the production estimate connects to your actual usage and utility rules. A generic national savings chart is not enough.
Questions to ask
- ✓ Which utility assumptions are being used for OG&E, PSO, a municipal utility or a co-op?
- ✓ How does the proposal model exports, fixed fees, future usage changes and seasonal AC load?
- ✓ What annual production estimate is used, and what shade or roof-plane assumptions drive it?
- ✓ If a battery is included, is the value backup power, bill control, or both?
Electrical scope
Electrical, battery and EV-readiness questions
Solar is an electrical project. The best proposal for one house may change if the main panel is full, if EV charging is planned, or if the homeowner wants battery backup.
Questions to ask
- ✓ Who verifies main-panel capacity, breaker space, grounding, disconnects and inspection requirements?
- ✓ Are panel upgrades, SPAN, EV charging or battery circuits separate line items?
- ✓ Will the design still work if you add battery backup later?
- ✓ Who owns the final inspection and utility-interconnection sequence?
Proposal and financing
Price, financing and scope-comparison questions
Do not compare only monthly payment. Compare the full scope, cash price, loan terms, add-ons, service promise and what is excluded.
Questions to ask
- ✓ What is the cash price before financing, and are dealer fees or loan costs embedded in the financed price?
- ✓ What equipment, batteries, electrical work, permits and utility fees are included or excluded?
- ✓ What happens if the design changes after site survey?
- ✓ What is the service path if monitoring, production or workmanship issues appear after activation?
Red flags
Pause before signing if the proposal cannot answer the basics
The quote only shows a monthly payment, not the cash price and full scope.
The roof age, attachment method and future roof replacement plan are vague.
Utility assumptions are generic and not tied to your usage history.
Electrical-panel, battery or EV-charger work is treated as an afterthought.
The installer cannot explain permits, inspection and interconnection timing.
Service, monitoring and workmanship responsibility after activation are unclear.
