What the sun does in Kalispell

• A south-facing roof at a 30° pitch makes about 1,197 kWh per kW a year before snow and 1,151 after a 4% snow allowance, 8% below the Montana average.
• July is the best month at about 168 kWh per kW; December the worst at about 26. 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.
