Bird droppings on solar panels

Are bird droppings bad for solar panels?

Furthermore, corroborative research indicates that bird droppings can reduce the output power of solar PV cells by up to 23.8% 4. Over time, bird droppings can have detrimental long-term effects on solar panels. Their acidic nature gradually corrodes protective coatings, such as anti-reflective coatings, leading to decreased efficiency.

Do birds affect solar panel efficiency?

Extensive research has highlighted the significant impact of birds, particularly their droppings, on solar panel efficiency. The accumulation of bird droppings obstructs sunlight from reaching photovoltaic cells, resulting in reduced electricity generation.

How do I prevent birds from perching on solar panels?

Mitigating bird droppings on solar panels involves several strategies. Installing deterrents such as spikes or nets around panels can discourage birds from perching. Regular cleaning of panels to remove droppings is essential. Utilizing repellents or sound-emitting devices may also deter birds.

Can pigeon droppings damage solar panels?

Acidic pigeon droppings, also known as guano, can accumulate on the solar panels causing damage to the glass. This debris, if not professionally cleaned often, will not only impact the solar panels ability to generate energy and result in a higher tru-up bill, but will also expedite the wear and tear of your expensive solar panel investment.

What happens if birds nest under solar panels?

Birds nesting under your solar panel system can lead to corrosion due to bird droppings becoming trapped around the frame supports. This will eventually void any warranty you hold with your installer.

How do I remove birds from my solar panels?

First, you need to remove any twigs or debris from the area under your solar panel system using a broom or rake. Cleaning early in the morning when birds will not return is best! Next, use a mild detergent and warm water to remove the bird droppings from your solar panels.
