Solar Irradiance in North Dakota (2026)

North Dakota receives an average of 4.2 peak sun hours per day annually, equivalent to roughly 1533 kWh/m² per year of global horizontal irradiance (GHI). Summer peaks reach about 5.5 h/day, while winter lows drop to around 2.5 h/day.

This places North Dakota in the good solar irradiance band compared with other US states. At 4.2 kWh/m²/day, each 1 kW of rooftop solar in North Dakota generates approximately 1,196 kWh/year (assuming 78% system performance after inverter, soiling, and temperature losses), which makes an 8 kW system produce around 12,264 kWh per year.
