"Peak sun hours" does not mean the total hours of daylight. It refers to the equivalent number of hours per day when solar irradiance averages 1,000 watts per square meter. This number varies heavily by geography. For instance, the desert Southwest of the United States might receive 6 peak sun hours per day, while the Pacific Northwest might average closer to 3.5.
