6 FAQs about [Standard value of photovoltaic panel dirt coefficient]

How efficient is a photovoltaic panel?

Due to inherent material property of semiconductor, efficiency of PV system is limited within 15–20% . However, depends on module design, installation and environment, each photovoltaic panel has different level of performance. Dust is one of the environmental factors that should be considered in optimizing PV panel efficiency.

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 dust deposition affect solar PV panel efficiency?

Density of dust deposition on a panel surface depends on dust properties, environment, weather, module properties and its installation design. Appropriate countermeasures as proposed earlier should be taken to eliminate or reduce the effect of dust on solar PV panel efficiency.

Does surface soiling affect power generation of photovoltaic modules?
