Nebraska's solar resource peaks in June at 6.9 peak sun hours per day and bottoms out in December at 2.71. That December figure is the one that matters most for sizing.

What 4.98 Peak Sun Hours Actually Means

A peak sun hour represents one hour of solar irradiance at 1,000 watts per square meter. Nebraska gets far more daylight hours than 4.98, but the sun isn't always at peak intensity. Peak sun hours compress a full day's variable sunshine into an equivalent number of full-power hours.

In practical terms, 4.98 PSH means a 400W solar panel in Nebraska produces about 1.49 kWh per day after real-world losses.

Best and Worst Months

June is the best month at 6.9 PSH. A 5 kW system produces roughly 34.5 kWh per day — nearly 2.5x what it produces in December.

December is the weakest month at 2.71 PSH. Size your system for December to ensure year-round coverage.

Is Solar Worth It in Nebraska?

With 4.98 PSH, Nebraska has good solar potential. The federal ITC covers 30% of installation costs through 2032.

State-specific incentive data and payback calculations will be added in a future update. Check the DSIRE database for current Nebraska solar incentives.
