Sun on a roof in Marlin.
The PVWatts model puts a generic roof array in Marlin at 1,503 kWh a year for each kW of panels, using typical-year weather from a station 2.4 km away. A modeled estimate for a standard setup, not a measurement of any roof.

How Marlin comparesderived from the figures above
Where Marlin sits.
Marlin ranks 722nd of 1220 Texas places modeled here, at the 41st percentile. Its 1,503 kWh per kW is below the Texas median of 1,515. The strongest months are July, August, June and the weakest are December, January, February; output peaks in July and bottoms out in December. In all, 29.7% of the year arrives in June, July and August, more than the 29.3% of the median place.

Against Austin
The nearest of the six largest modeled places is Austin, 139 km to the southwest, at 1,483 kWh per kW. Marlin models 20 kWh per kW (1.3%) above it. Marlin lies 1.01 degrees of latitude north of Austin, 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 (2.4 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, 165 km north, where the same model gives 1,500 kWh per kW, so Marlin runs 3 above that figure. Against the Texas median place month by month, Marlin runs at least 2% higher in April, October. It runs at least 2% lower in January, March, December.
Electricity in Falls CountyEIA-861
Electricity prices nearby
EIA lists Oncor Electric Delivery in this county. Where Marlin is on Oncor Electric Delivery's lines, homes buy energy from a retail electricity provider and the price depends on the plan. Parts of Marlin 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 1,503 kWh at $230 per kW a year, plain multiplication and not a savings estimate or an offer.
Also listed in the county
- Entergy Texas Inc.: 13.89¢ per kWh, a bundled average, 469,094 residential customers across 27 counties.
- Navasota Valley Elec Coop, Inc: 16.26¢ per kWh, a bundled average, 19,861 residential customers across 9 counties.
- Heart of Texas Electric Coop: 11.89¢ per kWh, a bundled average, 18,476 residential customers across 7 counties.

These utilities serve other parts of the county, which can include parts of Marlin. 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 Marlin 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 $231 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.
