Against Houston

The nearest of the six largest modeled places is Houston, 72 km to the northwest, at 1,422 kWh per kW. Tiki Island models 68 kWh per kW (4.8%) above it. Tiki Island lies 0.49 degrees of latitude south of Houston, and the sun stands higher in the sky the further south you go, which matches its higher modeled output. The two weather stations sit a similar distance from their points (1.5 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 Austin, 296 km northwest, where the same model gives 1,483 kWh per kW, so Tiki Island runs 7 above that figure. Against the Texas median place month by month, Tiki Island runs at least 2% higher in May. It runs at least 2% lower in January, February, June, July, August, November, December.

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 1,490 kWh at $228 per kW a year, plain multiplication and not a savings estimate or an offer.

Size the array, see the kWh.

Scale the Tiki Island 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 $229 per kW a year as plain multiplication.
