Sun on a roof in Petrolia.
The PVWatts model puts a generic roof array in Petrolia at 1,577 kWh a year for each kW of panels, using typical-year weather from a station 0.9 km away. A modeled estimate for a standard setup, not a measurement of any roof.

How Petrolia comparesderived from the figures above
Where Petrolia sits.
Petrolia ranks 261st of 1220 Texas places modeled here, at the 79th percentile. Its 1,577 kWh per kW is above the Texas median of 1,515. The strongest months are June, May, July and the weakest are December, November, January; output peaks in June and bottoms out in December. In all, 29.3% of the year arrives in June, July and August, about the same than the 29.3% of the median place.

Against Fort Worth
The nearest of the six largest modeled places is Fort Worth, 159 km to the southeast, at 1,535 kWh per kW. Petrolia models 42 kWh per kW (2.7%) above it. Petrolia lies 1.23 degrees of latitude north of Fort Worth, which on sun angle alone would point the other way, so clouds, haze and the weather station's record carry the difference. The two weather stations sit a similar distance from their points (0.9 km and 1.5 km), so station distance does little to explain the gap, and the weather record does the rest.
The second-nearest large place is Dallas, 192 km southeast, where the same model gives 1,500 kWh per kW, so Petrolia runs 77 above that figure. Against the Texas median place month by month, Petrolia runs at least 2% higher in January, February, March, April, May, June, September. It runs at least 2% lower in December.

Electricity prices nearby
EIA lists Oncor Electric Delivery and Texas-New Mexico Power in this county. Where Petrolia is on Oncor Electric Delivery and Texas-New Mexico Power's lines, homes buy energy from a retail electricity provider and the price depends on the plan. Parts of Petrolia may instead be served by a co-op or utility listed below, which sets its own rates; check your bill. For scale only, the median 2025 average price across the 60 Texas retail providers on this site is 15.32¢ per kWh, which would put the modeled 1,577 kWh at $242 per kW a year, plain multiplication and not a savings estimate or an offer.
Also listed in the county
- Wise Electric Coop Inc: 15.33¢ per kWh, a bundled average, 20,682 residential customers across 7 counties.
- Oncor Electric Delivery Company LLC: 5.64¢ per kWh, delivery charges only, before the retail energy price, 3,545,814 residential customers across 99 counties.
These utilities serve other parts of the county, which can include parts of Petrolia. They are the largest bundled providers, and the largest delivery-only one, whose EIA service territory lists the county. A county can list several, and which one serves a street depends on the address, so check your bill.

Size the array, see the kWh.
Scale the Petrolia model to another array size, take off extra losses for shade or dirt, and price the energy at any rate. It is arithmetic on the PVWatts output above, nothing more: not a quote, not a savings estimate and not advice.
Starting rate: the Texas residential average of 15.4¢ per kWh. At that rate the modeled output is worth $243 per kW a year as plain multiplication.

Getting a measured number
A model cannot see your roof. Installers measure pitch, shade and the electrical panel on site. Quote marketplaces such as EnergySage, SolarReviews and WattBuy collect bids from local installers. Rate & Roof does not rank installers.

Payback, buyback.
The sliders above price the energy at one rate. The payback calculator adds the system cost and your buyback plan type, and shows every assumption. It is an estimate, not advice.
