For Remote Off-Grid Industrial Sites, Use Solar PLUS Wind

. . . or so an advocate maintains, writing on RenewableEnergyWorld:

Remote power systems need to be designed for the worst case scenario, which is typically in the dead of winter,” says Busenlehner.  “In winter, there is only an average of 4 to 4.5 hours of sun per day in South Texas, and only three hours of sun per day in the Dakotas according to the Department of Energy.  In the worst case, there is no sun for potentially long periods of time.”

Wind power complements solar power because it often produces the most power precisely when solar power is reduced or unavailable, such as at night, in inclement weather, and during winter.  Wind often blows during long winter nights and is, on average, actually stronger in inclement weather.  During winter, average wind speed is highest, as is air density, both factors that contribute to wind generating more power when solar power tends to be least available.
