Partial shading (e.g., bird droppings, leaves, dusts, and shadows) on solar photovoltaic (PV) panels not only depresses the energy performance of solar PV panels but also increases their surface temperature.
Through analysis, temperature rise at shaded cell, power drop of solar PV panels and short circuit current drop of solar PV panel were selected as three quantitative criteria to evaluate energy reduction and fire risk caused by partial shading.
The power generation of solar PV panels is closely related to the received solar irradiance. The shadow will directly reduce the effective irradiance the solar PV panel receives, resulting in decreased power generation. Additionally, the rise in temperature of shaded cells reduces the power generation of solar PV panels.
There is a slight difference in performance between the cells in solar PV panel, leading to differences in the energy released in the form of heat after the cells in different locations are shaded. It results in different temperature rises and leads to differences in energy reduction level caused by partial shading.
