6 FAQs about [Cement spots on photovoltaic panels]

How does soiling affect PV panels?

Ultimately, the impact of soiling accumulation on the optical and thermal properties of PV panels is reflected in the electrical performance, and if the soiling is not removed in time, the power generation efficiency of PV panels will be significantly reduced, affecting the solar utilisation rate of PV modules and power generation revenue.

Does soiling accumulate on photovoltaic panels?

Soiling accumulation on photovoltaic panels and soiling removal challenges in different regions of China where photovoltaic power stations are located. This paper reviews the accumulation of soiling on the surface of PV panels and the methods of soiling removal, and the summary and outlook are as follows:

What are solar PV panels?

Solar PV panels (hereinafter referred to as ‘'PV panels'’) are the core components of PV power generation systems, and their structure is shown in Figure 2 . Among them, PV cells receive solar radiation and convert solar energy into electrical energy via a conversion process called the PV effect .

How are soiling particles deposited on the PV panel surface?

Soiling particles from a wide range of sources are deposited onto the PV panel surface through the aerodynamic system.

Why do PV panels have a hot spot effect?

It has been shown that the shading of the PV panel area leads to the hot spot effect, and the short-circuit current of the PV cell in the shadowed area is lower than the operating current of other PV cells, thereby causing reverse bias, and the electric energy generated by other PV cells is lost as heat.

Do construction materials affect PV panels' performance?

Abass et al. (2017) examined experimentally, in Iraq, the impact of three kinds of construction materials (cement, plaster, and borax) on PV panels' performance. They found that plaster revealed a minimum efficiency of about 25.8% degradation in comparison to a clean panel.
