Why should I clean solar panels?

Why is the cleaning and maintaining your solar panels 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 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 the professionals?
It’s certainly cheaper to wash your panels yourself. There are, however, important aspects to think about regarding:
safely avoiding damage that would invalidate the panels’ warranty
We always recommend that you just ask the manufacturer before attempting to scrub the solar panels yourself.
If you continue to shall we go ahead with the cleaning, here are some tips:
- 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 permanent damage. You can buy special water softeners online.
- Clean when the weather’s cooler and darker because the panels won’t be as hot.
- Some manufacturers advise against spraying cold water onto hot panels, while there’s also the difficulty of your soap solution drying and leaving streaks before you’ll be able to rinse it off.
