Solar panel cleaning in Lighthouse Point, FL
Lighthouse Point is small, almost entirely single-family, and almost entirely on the water. The city is a grid of canals off the Intracoastal, so most homes have a dock, a lot of them have a boat, and every one of them is within a few hundred yards of salt water. The homes around the Lighthouse Point Yacht Club and along the canal streets off Lighthouse Drive are large, the roofs are mostly barrel tile with some newer metal, and the arrays are big. There are no subdivisions to name here; the whole city is the neighborhood.
Salt film is the story
One block from the Intracoastal and a mile from the ocean, Lighthouse Point roofs get marine aerosol every day of the year. It settles on the glass as a thin salt haze that you cannot see from the driveway and that cuts output steadily. Rain does not rinse it. A garden hose makes it worse, because tap water dries into calcium spots on top of the salt.
This is why the cleaning method matters more here than anywhere inland. Deionized water has its dissolved minerals removed. It lifts the salt film with a soft brush and dries with nothing left behind, no spots, no residue, nothing for the next day’s salt to stick to. That is the whole reason we carry a deionizing system on the truck instead of a hose.
Lighthouse Point is a quarterly-plan city for us. Twice a year leaves too much salt between visits; four visits, February, May, August, and November, keep the glass clear through the pollen, the summer Saharan dust, the wet-season algae band, and the storm season. The maintenance plan puts them on the calendar at a discount and sends the photo report to your phone, which suits the seasonal homes here.
Boats, docks, and seabirds
Waterfront living comes with gulls, pelicans, cormorants, and the occasional heron on the dock pilings and the roof. Their droppings are large and land on the panels rather than under them, and in the sun they bake on within a day. They come off with deionized water and the soft brush. The tile-roof homes also get pigeons roosting under the array edge like everywhere else in Broward; see the bird guard section below.
Tile and metal, worked from the pole
Barrel tile cracks underfoot, so we clean from a water-fed pole at the roof edge wherever the array can be reached, and use walk pads on the tile overlap when a panel is out of reach. Standing-seam metal is cleaned from the pole and never walked wet. Every panel is photographed before and after, and the photos come with a condition note the same day. No pressure washing, no detergents. Month-by-month detail on the salt, the pollen, and the dust is on the soiling calendar.
