Birds poop; it’s a proven fact. And they are not too picky about where they do it either. In fact, this is how Gary Larson thinks birds see the world:
Cynical, yes – but how else to explain those strategically-placed bird droppings on your freshly-washed car?
Here in the solar world, we tend to think that this is how birds see solar panels too. Either that, or with a “Space for Rent” sign since they also like to build nests under the panels.
Solar panels create a nice, cool spot that is perfect for helping to keep your house cooler during the summer. It’s also the perfect place for birds to build their nests. This in itself is generally fine, but with nests come lots of poop. And most people don’t like the idea of mounds and mounds of bird droppings piling up on their roof (and definitely not on top of their panels).
What to do? Fortunately, there are a variety of solutions to the problem. From practical to wicked awesome, here are a few items that can help protect your panels:
1. Bird mesh: To seal up the area under the panels, you can install a wire mesh that clips directly to the solar panels and goes completely around the entire array. Or for a less expensive version, plastic bird netting will pretty much do the same thing but may not weather the elements as well.
2. Spikes: they may look medieval, but spikes along the edges of your panels make things uncomfortable and will help keep the birds from hanging out long enough to make a mess.
3. Plastic birds of prey: The old fake owl trick still works, believe it or not. Especially if its head swivels around in the breeze. Or if you want to go really high-tech, take a looksy at Brian the Robotic Peregrine Falcon who guards the solar panels at a science center in the UK.
And sometime it’s not the birds you need to look out for. Bees and wasps look for cool spots to build their nests and hives too. But they tend to get their creations tangled up in all of the wires (as pictured below). Wasps are a lot more aggressive than birds when you disturb their home so be careful when examining them. It’s a lot harder to try and keep them away but if they do become a nuisance, best to call a professional for hive removal. Remember, safety first!
Whether you decide to live in mutual harmony with your panel-dwelling friends or take steps to keep things animal/pest free, choosing the most humane way to do so is always the most eco-friendly way to proceed.
