Do photovoltaic modules accumulate sand and dust?

Dida et al. examined the accumulation of sand and dust on photovoltaic (PV) modules in a Sahara desert environment through experimental methods. After eight weeks of exposure, the modules amassed approximately 4.36 g/m 2 of sand and dust.

Does sand and dust affect PV module output power?

Wu et al. measured the PV modules’ output power in the Dali region before and after dust accumulation. Between January and May, without rainfall interference, the decrease in PV module output power attributable to sand and dust was consistent, resulting in an 11.4–13.3% reduction in power generation efficiency.

How does sand erosion affect photovoltaic power generation?

Author to whom correspondence should be addressed. Photovoltaic power generation is one of the most effective measures to reduce greenhouse gas emissions, and the surface of photovoltaic modules in desert areas is mainly affected by sand erosion and cover, which affect power output.

How much sand does a PV module have?

Chen et al. implemented controlled dust deposition experiments on PV modules, establishing three distinct sand and dust coverage densities: 10 g/m 2, 20 g/m 2, and 30 g/m 2. Their results demonstrated that a dust density of 10 g/m 2 led to a 34% reduction in the PV module’s peak output power.

What is the difference between sand deposited and clean photovoltaic modules?

It can be seen from the figure that the output power of the sand-deposited photovoltaic module is significantly lower than that of the clean photovoltaic module. The smaller the particle size, the greater the influence on the output power, and the maximum difference is about 17%.

How does sand particle size affect the performance of solar photovoltaic modules?

In essence, the performance impact of solar photovoltaic modules is generated by the joint effect of sand particle size and temperature, which belongs to the correlation relationship.
