Solar Panel Cleaning in Leichhardt

The roofs set the shape of the array. Hipped and gabled forms are the norm in the Leichhardt Street and Stanley Street area and in the Scarvell Estate, which breaks each roof into several smaller planes, and the elaborate chimneys there can throw shade across nearby panels at certain times of day. An array split across planes and partly shaded relies even more on clean glass for the hours it does get full sun.

Metal roofs are common too. Iron predominates in the Excelsior streets between Parramatta Road and Marion Street. In September 2025 we cleaned a rooftop system on a corrugated metal roof in Leichhardt using a water-fed pole and purified water, which dries spot-free on the glass.

What lands on the panels varies from street to street. Carlisle Street's crepe myrtles drop spent flowers in summer and leaves in autumn, the brush box planted in the roadway on North Avenue and South Avenue shed leaves and capsules, and the mix of natives and deciduous trees around Norton Street adds pollen in season. Near busy roads such as Parramatta Road and the City West Link, soot from passing traffic can settle on the glass too, and a passing shower may not shift it on its own.

On a small system there is no spare capacity to absorb dirty glass. Panels are commonly wired together in strings, so a patch of leaf litter or droppings across one panel can pull down the output of the panels it is connected to, not just its own. Clearing the whole array evenly gives each panel the same chance to produce.

Purified water is how we avoid leaving anything behind. It carries no detergent and dries spot-free, so there is no residue for dust and pollen to cling to and nothing to dull the anti-reflective coatings many modern panels carry. That looks after the glass you paid for as well as what it generates.

It is also a job best kept off the domestic ladder. Tightly packed houses and narrow side passages rarely leave a comfortable place to stand one, and our team is certified to work safely at heights and fully insured, with $10 million public liability cover.

After a clean, it is worth comparing your inverter or monitoring app figures with the weeks before. Every job also includes before-and-after photos, so you can see exactly what came off the panels.
