Why cleaning your solar panels is so vital?
Out on the roof, your solar panels can accumulate layers of:
- tree sap
- bird droppings
These stop daylight from getting through to the panels, which makes them less efficient.
However, there’s debate over whether cleaning is critical. Some people recommend yearly cleaning, while others say it’s only needed if:
where you reside is especially dusty (e.g., beside a busy road)
your roof is exposed to bird droppings or trees (e.g. beneath power lines or near a park)
Unfortunately, letting the rain do the work may not work. Rainfall can actually worsen by washing dust into the corners of the panels. This causes them to heat up, which again lessens their efficiency.
Do-it-yourself or call within the professionals?

- Always shut off your system beforehand—this will remove any risk of you being electrocuted.

- Filter (or ‘soften’) H2O (tap water that contains lots of minerals) before you employ it to wash your solar panels. Untreated H2O can leave a layer of calcium on the panels that, over time, can cause them permanent damage. You can buy special water softeners online.
