Rooftop residential solar panels are an excellent way to supply your power and reduce your carbon footprint. However, they have an unexpected downside and that is birds. Unfortunately, birds and solar panels are not a good combination, and this post explores some reasons why birds nesting under your solar panels can be detrimental and how you can protect your investment.
They Can Cause Permanent Damage
Birds, especially pigeons, love nesting under solar panels because they provide shelter from the elements and predators. However, these feathered tenants are far from ideal. Droppings contain uric acid, which is highly corrosive and over time this acid can eat away at your solar panels, leading to permanent damage. The cost of replacing damaged panels can be significant, especially considering the that will have to be installed by a qualified solar installer or licensed electrician.
There’s a Reduction of Energy Output
The primary function of solar panels is to harness the sun’s energy to generate electricity. However, if the droppings cover the panels, they block sunlight reducing the system’s efficiency. Even worse, this reduction can affect other panels connected in the same string, significantly lowering the overall efficiency of your solar array. This drop in performance can lead to higher utility bills, defeating the purpose of investing in solar energy. So by keeping birds away, you ensure your system operates at peak efficiency.
There is an Increased Fire Risk
Birds pose a fire risk in two main ways. First, their nests are typically made of dry, combustible materials that can easily catch fire, especially during hot summers. For residents of Western Australia, where temperatures can frequently exceed 35 degrees celsius, this is a serious concern. Second, birds often peck at the wiring of solar panels, exposing electrical components. The combination of dry nesting materials and damaged wiring is a fire hazard. To mitigate this risk, it’s crucial to implement effective bird control and proofing measures for your solar panels.
They Spread Diseases
They are known carriers of diseases such as histoplasmosis, cryptococcosis and psittacosis. These diseases can be transmitted to humans through inhalation of dried bird droppings and as the droppings dry, they can become airborne and spread around your property posing a health risk. Protecting your solar panels from nests not only safeguards your system but also protects your health and the well-being of your household.
Create Unwanted Noise
Birds nesting under your solar panels can create a lot of noise, especially during the early morning hours. Pigeons, in particular are notorious for their incessant cooing and squabbling. This noise can be highly disruptive, affecting your sleep and overall quality of life.
Attract Other Pests
Their nests can also attract other pests, such as cockroaches and rodents. These pests are drawn to the warm, dry environment of the nests and the potential food sources they provide. Rodents can cause significant damage by chewing through electrical wires, leading to potential short circuits or fires. Efficient pest control can ensure you help keep these secondary pests at bay and protect your solar investment.
