Solar power exhibits peak output during daylight hours, while wind power can be harnessed even during periods of reduced solar availability .
Do wind resources complement solar energy?
“Wind resource tends to complement solar resource,” says Sarah Kurtz of the U.S. Department of Energy’s National Renewable Energy Laboratory. “Here in Colorado, for instance, the windiest time is during the winter and spring months. In winter, we don’t have as much sunshine, but we tend to get more wind and stronger wind.”
