This is possibly achieved through the proper cooling and cleaning process. The thermography of solar photovoltaic panels proved that under bird guano accumulation, the frontside temperatures were higher by 5% with hot spots as compared to clean module.
Bird guano droppings decreased the current, power, and efficiency of the solar photovoltaic panels by 38, 26, and 43%, respectively, which means a greater accumulation of bird guano on the solar modules could have a noticeable impact on their performance.
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.
External influences that can cause solar panel fires include moisture and water ingress into parts of the PV system, such as the DC and AC connectors. Additionally, consideration should be given to things such as build-up of dirt, bird droppings, and foliage on PV panels. These can lead to shading, causing hot spots that can escalate to burning.

Comprehensive Guide to Hot Spot Risks in Solar Panels: From Bird Droppings and Leaf Shading to Power Loss and Encapsulation Degradation — Detection Methods, Risk Mitigation, and
Besides, regularly cleaning and maintaining solar PV panels, especially removing bird droppings, dust, and other substances that can cause partial shading, is also contributory to
Bird droppings reduce solar efficiency by up to 23%. A cleaning and cooling system keeps your panels working at their best, saving you more on energy costs.
Reduced Energy Efficiency Solar panels need sunlight to create electricity. Anything blocking that light—like bird droppings—cuts their output. Even a little bit of droppings can cast a
Solar panels are a significant investment—and they should pay off. To ensure a photovoltaic system on the roof operates at full capacity, it must remain clean. While rain and snow
Renewable Energy, 2025, vol. 246, issue C Abstract: Partial shading (e.g., bird droppings, leaves, dusts, and shadows) on solar photovoltaic (PV) panels not only depresses the energy
The current study introduces a novel dual-cooling technique to enhance the performance of the SPV panels under conditions of contamination from bird droppings.
Ensure roof materials are non-combustible, and where applicable, apply a fire-resistant covering. Implement a system whereby solar panels are regularly cleaned by a suitably trained
