Various environmental factors can influence the efficiency of solar panels, leading to a reduction in power output. Some of the key factors include:
Accumulation of dirt and debris: Dust, dirt, pollen, bird droppings, and other airborne pollutants can settle on the surface of solar panels. Over time, this accumulation can block sunlight and reduce the panel’s energy conversion rate.
Seasonal challenges: Different seasons present various challenges for solar panel cleaning. Snow in winter, fallen leaves in autumn, and pollen in spring can all hinder solar panel efficiency. Each season may require a different approach to cleaning.
Bird droppings: Although a single bird dropping may not have a significant impact, the accumulation of bird droppings over time can substantially reduce solar panel output.
Dirt accumulation around the frame: Rainfall may only sometimes clean dirt accumulated around the aluminium frame of solar panels. This can lead to energy losses and even hotspots.
Debris: If your location is prone to debris from nearby trees or high winds, larger particles can become lodged between the panels, causing shading and impacting energy production.
Fungi, lichen, or mould: These growths can affect roofing materials, but they can develop on solar panels over time, reducing efficiency.
Particulate exhaust or dust: In industrial areas, nearby factories may release byproducts that adhere to solar panels and are difficult to clean.
