Why the utility matters more than the city
Oncor sets your export credit, your fixed monthly charges and your interconnection process. Two identical roofs on either side of a service-territory boundary can have quite different payback for that reason alone, which is why a quote built on a statewide average is worth less than one built on your actual tariff.
There is no statewide rule requiring utilities to credit exported power at a set rate. What you are paid is a decision your specific utility makes, and it can differ enormously between two utilities an hour apart.
This is the case where the utility matters more than the state. Two identical roofs on either side of a service-territory boundary can have quite different payback.
What a system costs in Dallas
Pricing here sits within the national band of $2.50–$3.50 per watt before incentives, so a typical 6 – 8 kW system lands around $15,000 – $28,000. Labour rates, permitting fees and whether your electrical panel needs upgrading move that figure more than the panel brand does — the full breakdown is in what solar panels cost.
When it does not pay here
- A roof with under about ten years left. Replacing it later means paying to remove and reinstall the array.
- Heavy shade for much of the day — micro-inverters help at the margin, they do not manufacture sunlight.
- A bill under roughly $80 a month. There is not enough there to offset.
- Moving within about five years. You will likely recover some of it in the sale price, not reliably all of it.

Common questions about solar in Dallas
How much do solar panels cost in Dallas?
A typical Dallas home needs about 6 – 8 kW, which lands around $15,000 – $28,000 before incentives at the $2.50–$3.50 per watt most US homeowners see. Your roof, your consumption and whether you need a panel upgrade move that more than the equipment brand does.
Which utility serves Dallas?
Oncor serves most of Dallas. That matters more than the state does: your export credit, your fixed charges and your interconnection process all come from the utility, not from Texas as a whole. Confirm your own account before sizing anything.
How much sun does Dallas get?
Around 4.8 – 5.6 peak sun hours a day, which works out to roughly 1,350 – 1,700 kWh a year for every kilowatt installed after normal system losses.
Is solar worth it in Dallas?
Texas runs no statewide mandate and residential rates here are around 14–18¢ per kWh. That makes it a reasonable proposition for a home with an unshaded roof and a bill above roughly $100 a month, and a poor one for a small bill or a heavily shaded roof.
