What the sun does in Red Lodge

  • A south-facing roof at a 30° pitch makes about 1,349 kWh per kW a year before snow and 1,275 after a 5% snow allowance, about the Montana average.
  • July is the best month at about 155 kWh per kW; December the worst at about 47. Net metering carries the summer surplus into winter, which is why the net-zero size and your utility’s bank reset month both matter.
  • Roof direction and pitch change the yield by a quarter or more; the estimate reads your actual roof from satellite imagery and fills south-facing planes first.
  • Electric heat roughly doubles a January bill compared with July, so a winter bill from an electrically heated house is annualized with a Montana heating profile rather than multiplied by twelve.
