Should photovoltaic cells be able to generate electricity from snow?

The Nordic countries in particular will experience long periods of snow cover each year, and it seems clear that some measures need to be taken against snow to keep photovoltaic cells a viable means of electricity generation.

Do snow-related issues affect solar power production?

Photovoltaic panels enable electricity generation in isolated high-altitude locations, such as mountain cabins, as it is very expensive to extend cables to connect them to the power grid. Thus, the concern of snow-related issues affecting the electricity production of PV systems is not limited to boreal or polar regions.

Why do photovoltaic panels get covered by snow?

When photovoltaic panels are covered by snow, the heat generated in the semiconductor region inside the photovoltaic module due to the energy level difference of the pn junction and the resistance of the semiconductor can be utilized as 'load' for the photovoltaic cells.

How does snow affect PV systems?

Obstruction of solar radiation The main influencing factor of snow on PV systems is the blockage of solar radiation on the photovoltaic cells. In order to quantify and assess the importance of this, some understanding of the optical properties of snow is required.

Can photovoltaic panels remove snow?

Photovoltaic panels can remove snow when the snow thickness is greater than the equivalent height and the inclination angle is greater than the required minimum inclination angle. Experimental studies have shown that the method proposed in this paper achieves this purpose for such conditions.

Do snow and ice affect photovoltaic panels?

Snow and ice will under various circumstances cause both uniform and partial shading. It is necessary to examine the behaviour and influence of snow and ice on photovoltaic panels, to accurately determine and improve the long-term performance of solar power in snow-prone areas.
