The average pigeon proofing job could cost you between $200 – $1500. However, it could cost you more depending on how many solar panels your system has, the angle of your roof, how high the roof on your home (or business) is and if birds and nests need to be removed prior to the installation.

Use a dry or damp cloth to gently wipe any dirt or dust off the panel. Make sure your cloth is only damp – not wet – as you want to avoid water damaging the electronics within the panel. For more stubborn grime, add some biodegradable soap to your damp sponge and give the solar panel a scrub.

Well, it depends, but most experts agree that cleaning solar panels an average of every six months is reasonable. However, there are times when you may need to get your solar panels cleaned earlier or wait longer. If you live in an area of dusty farmlands or the dessert, you'll need them cleaned more often.

For these birds, experts recommend installing Bird Control products for Rooftops, such as bird spikes. Spikes can be installed on to the peak where bird are perching. This will make it more difficult for pigeons to sit near the panels.
