Dust, pollen, and salt film build up on solar panels the same way it builds up on everything else this close to the coast, and most people never get up there to check. We clean panels safely from the ground using a WFP (water-fed pole) system, on houses and on larger commercial arrays, across East Auckland.
Tell us about your property and we'll be in touch.
A solar panel only generates power from the sunlight that actually reaches the cells underneath the glass. A layer of dust, pollen, or salt film sits between the sun and the cell, and every bit of it blocks light that would otherwise be converted to power. Panels facing the street or under trees pick up grime fastest. Flat or low-pitch panels are worse again, since rain doesn't run off them as easily as it does off a steep roof. None of this shows up as an obvious problem day to day, it just quietly shows up as a lower number on the inverter output over months.
Four steps, every time, whether it's a single residential array or a full commercial roof.
Panel type, roof pitch, and access all change how the job gets done, so we take a look before we start rather than treating every roof the same.
We use a water-fed pole with a soft brush head, controlled from the ground. No walking on the panels, no high pressure near the glass or the seals.
The water used is treated to leave the panels spot-free once dry, rather than trading dirt for water marks.
We look over the array once it's done to make sure every panel actually got cleaned, not just the ones easiest to reach, and complete an inspection checklist for the job so you've got a record of what was checked and cleaned.
Residential solar panel cleaning is usually a single array, done as a one-off or on a yearly schedule alongside a house wash. Commercial solar panel cleaning is a different scale entirely, larger arrays, harder access, and often a maintenance contract rather than a one-off call. The WFP system works for both, but a commercial array on a warehouse or office roof usually needs more time and, depending on the roof, the same EWP we use for commercial exterior cleaning.

Getting onto a roof to clean panels is a genuine fall risk, and it's not usually necessary. The bigger issue is the panels themselves: the wrong brush, too much pressure, or the wrong detergent can scratch the glass or damage the seals around the cells, and a lot of manufacturer warranties are specific about how panels should be cleaned. A WFP system avoids both problems, no one on the roof, and no pressure or abrasive contact on the glass.
Solar panel cleaning cost depends on a few things: how many panels are on the array, the roof's pitch and how easy it is to access, whether it's a residential or commercial job, and how long it's been since the last clean (a heavily soiled array takes longer than a light dust-off). A yearly or twice-yearly clean is usually more cost-effective than waiting until the array is visibly dirty. The only way to get an accurate number is a quick quote based on the actual property.
Most panels are fine with a clean every six to twelve months, but East Auckland's coastal position changes that math. Salt air settles on panels faster near the water, which includes most of Beachlands and the surrounding coastline, so properties closer to the coast are often better on the six-month end of that range. Overhanging trees add pollen and leaf litter regardless of how close to the water a property is. A flatter roof pitch also holds onto grime longer than a steep one, since rain doesn't rinse it off in between cleans.
It depends on the number of panels, the roof's pitch and access, and whether it's a residential or commercial array. The only accurate way to know is a quote based on the actual property, not a flat rate.
A WFP (water-fed pole) system, controlled from the ground with a soft brush head and treated water. No one walks on the panels and there's no pressure near the glass or seals.

A WFP system with a soft brush and no pressure is the method most manufacturers are comfortable with. If a specific panel brand has its own requirements, let us know before the job and we'll work around them.
Yes, both. Commercial arrays usually take more time and sometimes the same EWP we use for commercial exterior cleaning, depending on the roof.
Just treated water through the WFP system for most jobs. It's enough to lift dust, pollen and salt film without needing chemicals on the glass.
Yes. We complete an inspection checklist at the end of every solar panel cleaning job, covering what was checked and cleaned, so you've got a record on file.
