Work Package 3: Challenges with snow and ice formation.

wp3_ice_agi

The Norwegian climate is very diverse due to the country's large extension, spanning 13 degrees in latitude, with a long rugged coastline and a mix of plateaus and mountain ranges.

In winter, heavy snowfall is common in the mountains and inland regions, whereas coastal regions usually receive a combination of snow, sleet, and rain. Large temperature variations and ice formation on the PV module surfaces represent environmental stress factors and may reduce both yield and lifetime of such systems. Hence, surfaces that may prevent snow and ice from sticking to the PV modules are of great interest.

What is really snow and ice? Snow can actually be considered as a very HOT material:

This work package will include a PhD with title "Advanced Materials Surface Development for Preventing Snow and Ice Formation on BIPV".
