6 FAQs about [Photovoltaic panel attenuation phenomenon]

Are you experiencing a PID effect in a photovoltaic plant?

In case you are dealing with unexpected and unreasonable power loss in your photovoltaic plant, you may be experiencing the PID effect in the PV modules. Potential induced degradation (PID) is a phenomenon that arises over time (months or even years).

How do degradation mechanisms affect PV modules?

Although PV modules have long been considered reliable under field conditions with low degradation and failure rates, they can be affected by diverse degradation mechanisms, which collectively reduce the module crop power over time. One of the main degradation mechanisms is called potential-inducted-degradation (PID) 1, 2, 3.

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.

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.

Which environmental factors should be considered in optimizing PV panel efficiency?

Dust is one of the environmental factors that should be considered in optimizing PV panel efficiency. Kaldellis and Kokala stated that solar radiation intensity on panel surface is the main factor which affects a PV panel's output, but soil and dirt can cause further degradation up to 15% of the efficiency.

Why do PV panels lose performance if it rains?

Dust promotes dust, hence, small initial dust settlement can lead to significant performance drop, especially for unattended PV panels installed in remote areas. Dust effect is time dependent and site specific. Without proper and regular cleaning, dust accumulated on panel surface will thicken and might not be easily dislodged by rain .
