Pigeons under Solar Panels

Good morning. Hope someone can help. We have had pigeons nesting under our solar panels for a couple of years. As you can imagine they are making a mess of our roof and the ground under the panels. We also have a 2 year old who is starting to get into everything. We are starting to worry that he may end up with some sort of disease from the pigeon mess so we really want the pigeons removed from under the panels. I have contacted a few pest control companies but have been told they cannot remove nesting birds? Could someone please give some advice on what would be our next step. Thank you
