Bird Proofing
Solar panels offer a ready-made shelter for nesting under combined with a high vantage point from which to survey the surroundings.
If there’s such a thing as estate agency in bird world, and in particular pigeon world, it’s easy to envisage the blurb on the sale particulars for a nest under a well-located 4kW array.
Of course the pigeon’s gain is the system owner’s loss. Nesting birds cause problems for solar panels and increase the need for general building maintenance.
Luckily the industry has now developed well-proven solutions for solar panel bird-proofing: solar mesh and solar bird spikes.
Why are nesting birds a problem for solar systems?
Birds nesting under or around the panels may
damage cables;
damage panels;
deposit droppings and other debris on the panels, thus reducing output;
present a fire risk if they nest under the panels;
block the roof’s drainage system with droppings, nest materials, food debris and feathers potentially causing roof leaks, whilst providing a nutrient rich environment from which vegetation can grow;
present a health hazard to any contractor working on the roof (contact with bird droppings can cause infection to humans).
