Does bird dropping deposition affect solar photovoltaic module performance?

Impact of bird dropping deposition on solar photovoltaic module performance: a systematic study in Western Rajasthan One of the most critical challenges is bird dropping deposition (soiling) on a glass surface of the photovoltaic (PV) module in an open environment of Western Rajasthan.

Does bird dropping affect the performance of a flat plate solar collector?

Bird dropping deposition adversely affects the performance of a flat plate solar collector. Research by Lmenes et al. has shown that PV module exposure to bird dropping conditions has caused a 2% reduction in the maximum power (Pmax) (Lmenes et al. 2011 ).

Do bird droppings affect the performance of solar PV cells?

Bird droppings can significantly impact the performance of solar PV cells, reducing the output power by up to ≈23.8% (at 0° tilt angle/horizontal) in the month of March, according to this research.

Do bird droppings affect SPV modules performance?

The results showed that bird droppings strongly affect the SPV modules performance causing a decrease in output power by 23.8%. In another study, Mustafa et al., 26 found that the bird droppings by 7.4% compared to the control (cleaned SPV modules).

What happens if a solar panel drops a lot?

If a solar panel is covered in a lot of bird droppings, the droppings will accumulate in the form of a periodic vertical strip shape, blocking the transmittance of sunlight on the PV surface. This results in more reduction of power, which is approximately ≈ 9.7% in this case.

Do bird droppings affect the performance of PV modules?

Bird droppings can affect the performance of PV modules by altering their transmittance profile. The transmittance measurements through the glass samples were carried out at the indoor laboratory to characterize this effect.
