Improved Snow Loss Modeling Accounting for the Orientation of Modules

The impact of snow losses on the performance of solar modules is unneglectable. Northern latitudes are expanding their solar energy portfolio and need reliable prediction methods and guidelines on how to reduce these losses. In this work, we compare the performance of landscape and portrait orientation for state of the art half-cut solar cell modules during winter months. We show how to adapt the Marion snow loss model to account for module orientation to improve performance modeling for PV systems affected by snow.
