6 FAQs about [Principle of photovoltaic snow shield]

Can a solar system remove snow from a grid-connected PV system?

Scientists in China have developed a new snow-removal system for grid-connected PV systems that uses electricity from uncovered PV modules to remove snow from solar arrays, string by string. The system, called the 'domino-like snow removal system' (DSRS), makes very little use of grid electricity.

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.

Can a photovoltaic panel self-heat to remove snow?

The study concluded that self-heating to remove snow on a photovoltaic panel is feasible when the snow thickness is greater than the equivalent height and the panel inclination angle is greater than the minimum inclination angle. It is concluded that this method is feasible.

Does snow removal affect the performance of PV modules?

The key conclusions are as follows: From the comprehensive experimental results of the long-term effect of photovoltaics self-heating, the snow removal method is verified to have no negative impact on the performance of PV modules;

How does snow affect photovoltaic power generation?

Snow accumulation on photovoltaic (PV) modules can reduce power generation up to 90% due to very high snow albedo (a measure of surface radiation reflectivity) (Andenæs et al., 2018). The PV technologies have attracted substantial investments from industries and governments, driving rise to their worldwide utilization.

Is a domino-like snow removal system based on photovoltaics self-heating (pvsh)?

In this paper, a domino-like snow removal system (DSRS) based on photovoltaics self-heating (PVSH) was designed and investigated to overcome this application challenge. The domino-like snow removal strategy is first proposed, whose core idea is to use the energy from uncovered PV modules to accomplish snow removal in PV systems string by string.
