Before making a purchase
Check your actual electricity plan, export credit, roof shading, insurance terms, and multiple installer proposals.
What changes in a McKinney solar estimate?
The calculator uses your bill and optional monthly kWh, plus a McKinney PVWatts reference yield of 1,526 kWh per year per 1 kW of solar capacity. ZIP 75069 is a representative city label; the yield comes from a separate city reference point, not an inspection of a particular home. It returns estimated system-size, installed-cost, generation, savings, and payback ranges using statewide electricity-rate and national cost benchmarks. Review the inputs and limitations.
Oncor delivery is common in McKinney; confirm your TDU from the bill for your address. Oncor carries grid power and charges for delivery, while your REP sells the electricity plan and may offer separate solar export credits. Electricity your home uses as it is generated can reduce imports, but exports follow your REP's contract rather than a guaranteed 1:1 credit. Read the Oncor guide and Texas buyback guide for those distinctions.
Actual output depends on roof orientation and shade; actual economics depend on your plan, installation proposal, and site conditions. The city reference is a starting estimate, not a property-specific quote or savings guarantee.
Local electricity context
Oncor delivery territory is common; retail plan terms vary by address. Confirm the TDU or municipal utility shown on your bill. Export compensation is not assumed to equal the retail price in this calculator.
Limits of this estimate
This model does not inspect a roof, shading, electrical panel, structural condition, financing offer, insurance policy, or current retail contract. A qualified site assessment can produce a different result.
