Honest numbers: Actual production depends on your roof's orientation, tilt, shading from trees and nearby structures, panel efficiency, inverter type, and Oklahoma weather. This estimate assumes ~5.5 peak sun hours per day and a 77% system derate factor, and caps savings at your current annual electric bill.

kW × 5.5 hrs × 365

Solar Payback Questions, Answered
How much does a solar-ready roof cost in Oklahoma?
A solar-ready roof in Oklahoma typically costs about the same as a premium asphalt shingle roof — roughly $5.50 to $8.00 per square foot installed — plus a modest upgrade for conduit, flashing, and a reinforced attachment layout. Proof Construction (CIB #80004070) has installed solar-ready roofs across the Tulsa metro since 2015, so your structure is ready when you add panels.
How is solar payback calculated?
Simple payback is your net system cost — after the 30% federal tax credit — divided by your estimated annual electricity savings. This calculator estimates annual production using Oklahoma's roughly 5.5 peak sun hours per day, multiplies production by your utility rate, and caps savings at your current annual electric bill so the numbers stay honest.
Does the 30% federal solar tax credit still apply?
Yes. The federal Investment Tax Credit (ITC) gives Oklahoma homeowners a dollar-for-dollar credit equal to 30% of the installed solar system cost for systems placed in service through 2032. It is a credit, not a deduction — it directly reduces the federal income tax you owe. Consult a tax professional to confirm your eligibility.
Will Oklahoma hail storms damage solar panels?
Solar panels are built for Oklahoma weather — most are UL-rated to withstand 1-inch hail at 50 mph, and racking is engineered for high wind loads. If a storm does damage your panels or roof, Proof Construction's insurance claim team documents the damage forensically so your policy covers what it should. Call (918) 734-4444 for a free post-storm inspection.
