What the sun does in Miles City
- A south-facing roof at a 30° pitch makes about 1,389 kWh per kW a year before snow and 1,321 after a 5% snow allowance, 5% above the Montana average.
- July is the best month at about 169 kWh per kW; December the worst at about 39. 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.
