Does ambient fine particulate matter affect surface solar irradiance & system performance?

CC-BY-NC-ND 4.0 . Ambient fine particulate matter (PM2.5) could be a potential environmental risk for decreasing the available solar energy resources and solar photovoltaic (PV) power generation. This study quantifies the attenuation effects of PM2.5 on surface solar irradiance and system performance of different solar PV technologies in Hong Kong.

How to maximize the efficiency of a solar panel?

This article presents a review on maximizing the efficiency of the solar panel by utilizing different cooling methods and by integrating TEG with solar panels. An abundance of innovations is transpiring to access green electricity concretely from the solar power generation sector.

How to achieve maximum efficiency from PV panels?

To attain the maximum efficiency from the PV panel few additional arrangements are required, such as the Sun tracking method (Awasthi et al., 2020), concentrating mirrors (Bilal et al., 2016), and applying cooling techniques to the panels, which can be classified as active and passive cooling.

How does temperature affect the efficiency of a PV panel?

A higher concentration level on the PV panel results in higher output power in TEG, but this causes a reduction in the efficiency of the PV panel due to high temperature (Zhang et al., 2014).

How does ambient irradiation affect a solar PV panel's efficiency?

It is clear in the literature that the open-circuit voltage increases logarithmically with ambient irradiation, while the short circuit current is a linear function of the ambient irradiation. An increase in temperature of the cell decreases the open-circuit voltage linearly, so the solar PV panel’s efficiency is decreased.

How does temperature affect photovoltaic efficiency?

On the negative side, the photovoltaic efficiency is reduced with an increase in ambient temperature. The production of energy is dropped by 0.33% for every degree Celsius above STC. Consequently, the electric power which is generated by the solar panel may not be sufficient to run the load.
