A Norwegian study has shown that vertical rooftop solar panels are more efficient in winter than conventional flat panels. Especially in snowy conditions, the energy production of these panels continues steadily.
According to the study, vertical panels can provide the same or up to 30% higher performance than flat panels in terms of annual energy efficiency. In winter, the energy they produce can be 3-4 times higher than flat panels. Under low snow cover, they continue to generate energy by taking advantage of the snow’s ability to reflect sunlight (albedo), while under partial snow cover they continue to operate thanks to their open areas. However, when they are completely covered with snow, energy production stops.
The design of the vertical panels allows the surrounding snow to melt faster. When exposed to sunlight, they create a flow of warm air over the snowy surface, helping the snow melt faster. They also offer less potential to damage the roof surface, contributing to the protection of roof insulation and coatings in cold climates.
This innovative approach aims to increase the use of solar energy in snowy regions and supports the wider applicability of solar technology.
