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 1,494 kWh at $229 per kW a year, plain multiplication and not a savings estimate or an offer.

Size the array, see the kWh.

Scale the Cumby 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 $230 per kW a year as plain multiplication.
