How Often Do You Need Solar Panel Cleaning in South Florida?

Most South Florida homes need solar panel cleaning twice a year: once in May, after the pollen tail, and once in November, when hurricane season ends. Homes near the beach or the Intracoastal, and homes with heavy bird activity, do better on a quarterly schedule. Those two dates aren’t arbitrary. Each one comes right after a season that coats the glass, and right before a stretch when you want the array producing.

Why twice a year works for most homes

What lands on panels in Broward and southern Palm Beach County follows the calendar, and the South Florida soiling calendar lays it out month by month. Most of it comes in two waves.

Spring: pollen. Oak and pine pollen starts in February and runs through May, peaking in March. It settles as a yellow film, and humid nights bind it to the glass. A clean in May, once the pollen tails off, clears it before the wet season arrives.

Summer and fall: dust, algae and storms. Saharan dust events arrive in June through August. The wet season starts algae and mildew in the band where water collects along the bottom of each panel, and hurricane season brings fronds and debris. A clean in November, after the season ends on November 30 per the National Hurricane Center, clears all of it going into the drier months.

Rain between visits doesn’t do the job for you. The afternoon storms move loose dust and leave the bonded film behind; we explain that in does Florida rain clean solar panels.

When to switch to quarterly

Two situations call for four visits a year instead of two.

You’re near saltwater. Salt lands on the glass every day, not seasonally, and it doesn’t rinse off. Homes in Lighthouse Point, the Fort Lauderdale neighborhoods on the Intracoastal, and east Boca Raton build a salt film between a May and a November visit. Our salt air guide explains why a quarterly schedule and deionized water matter near the coast.

Birds use your roof. Pigeons are year-round residents here. On roofs where they roost, droppings pile up on the panels below faster than twice a year can keep up with, and each one shades the cells under it. Most of the bird questions we get come from barrel-tile roofs in Parkland, Coral Springs and Coconut Creek. The pigeon guide covers what’s happening under the array too.

If you can only fit one cleaning a year

If a home can only fit one cleaning a year, make it November, so the panels go into the dry season clean. Skipping cleanings altogether is where it gets expensive. Film that has sat on the glass for a couple of years is harder to lift than film that’s months old.

How to tell your panels are due

You don’t need to wait for the calendar. Signs a clean is due:

• The glass looks hazy or spotted from the ground, or you can see droppings.
• Your monitoring app reads lower than on a similar sunny day a few months back. Film on the glass can cut output without looking dramatic from the driveway. Read the number and note it; we compare the app before and after a cleaning so you can see what the dirt was costing you.
• A storm just came through. Our post-storm checklist covers what to check first.

A visual inspection with a cleaning gives you photos of every panel, so the next time the app reads low you have a baseline to compare against.

Putting it on the calendar

The maintenance plan books the May and November visits for you at 15% off each one. There’s a quarterly option for coastal and bird-heavy roofs. If you spend part of the year away, the seasonal residents guide shows how we time the visits around your arrival and departure.
