Sun on a roof in Celina.
The PVWatts model puts a generic roof array in Celina at 1,521 kWh a year for each kW of panels, using typical-year weather from a station 2.2 km away. A modeled estimate for a standard setup, not a measurement of any roof.

Against Dallas
The nearest of the six largest modeled places is Dallas, 59 km to the south, at 1,500 kWh per kW. Celina models 21 kWh per kW (1.4%) above it. Celina lies 0.53 degrees of latitude north of Dallas, 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 (2.2 km and 2.4 km), so station distance does little to explain the gap, and the weather record does the rest.
The second-nearest large place is Fort Worth, 79 km southwest, where the same model gives 1,535 kWh per kW, so Celina runs 14 below that figure. Against the Texas median place month by month, Celina runs at least 2% higher in January, April, June, July, September. It runs at least 2% lower in October, November, December.
Electricity in Collin County, Denton CountyEIA-861
Electricity prices nearby
EIA lists Oncor Electric Delivery and Texas-New Mexico Power in this county. Where Celina 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 Celina 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 1,521 kWh at $233 per kW a year, plain multiplication and not a savings estimate or an offer.

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 Celina 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 15.47¢ per kWh. At that rate the modeled output is worth $235 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.
