The aim of this work is to (i) characterize the effect of snow in PV monitoring data, (ii) to assess and improve on existing PV snow loss models, and (iii) to develop snow detection methods for PV monitoring data. The main focus is on monofacial c-Si technology.
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. Studies on the optical properties of snow and ice have been performed for decades, since long before solar panels became commercially viable.
Snow is a significant challenge for photovoltaic (PV) systems at northern latitudes, where the pace of deployment is rapid but snow-related power losses can exceed 30% of annual production. Accurate snow-related power loss estimation methods for utility-scale sites can support snow mitigation strategies, inform resource planning and validate .
When the thickness of snow reaches 1 cm, the power generation efficiency of the entire photovoltaic module reduces to 7.1% of that as normal. At the same time, the sliding of snow on the photovoltaic panel improves the efficiency of photoelectric conversion.
As the photovoltaic (PV) industry continues to evolve, advancements in Photovoltaic support snow resistance level have become critical to optimizing the utilization of renewable energy sources. From innovative battery technologies to intelligent energy management systems, these solutions are transforming the way we store and distribute solar-generated electricity.

6 FAQs about [Photovoltaic support snow resistance level]
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.
Does snow cover affect PV energy generation?
In this paper we describe the effect of different types of snow cover on PV energy generation, and snow related signatures in PV monitoring data are identified. In addition to snow coverage and system configuration, transmittance and nonuniformity of the snow cover influence the total snow losses, increasing the complexity in snow loss modeling.
Does snow cover affect PV Monitoring data?
To characterize the impact of different types of snow covers on the measured variables of a PV system, we have analyzed data from two PV systems in Norway with regular snow cover in the winter. The identified signatures in PV monitoring data caused by snow, are assessed by using simulations of shaded modules and transmittance measurements.
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.
How to detect snow in PV Monitoring?
In PV monitoring, if at all considered, detection of snow is a more common approach than snow loss modeling. In the literature, snow detection methods based on dedicated or external sensors like weight sensors, web cameras and satellite data have been proposed ( Aarseth et al., 2018, Andrews et al., 2013, Wirth et al., 2010 ).
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.
