At high latitudes, vertical PV is more profitable in February than horizontal panels in June
A 248 kWp solar system deployed on the roof of Oslo’s Ullevaal Stadium was found to be more profitable in February than a comparative horizontal array in June. The vertical panels’ ability to generate more energy in winter months than horizontal equivalents helped save more money against Norway’s typically high electricity prices in winter.
