5 Quick Tips On How To Keep Your Solar Panels Clean

A lot of individuals presume solar panels cleaning to be a hassle. The assumption is also that panel maintenance demands a lot of your time and effort. We, at SunEdison, are here to help break that myth for you.

In this blog, we cover quick tips on how to keep your solar panels clean. These will be time saving and help aid in the maintenance of your panels. Do solar panels need cleaning? Yes. Depending on the type of panel you have and the dust / pollution in your area, you might have to clean your panels on a weekly or fortnightly basis.

Quick Tips:

  • The most effective way to clean your solar panels is with a hose or a bucket of water at room temperature. Do not use warm water. Essentially, in the same manner you would wash your car at home.
  • Avoid using harsh soaps & detergents as some soaps can leave a film or residue that not only leaves a mark, but also attracts dirt to stick to the surface and manifest longer.
  • Never use an abrasive sponge or soap for your solar panel cleaning as it may hamper the anti-reflective coating and scratch the glass. Both these conditions will render the panels void of their warranty. The best way to clean solar panels is by using a soft rag/soft mop or non-abrasive sponge.
  • Clean solar panels when they are moist or wet to ensure any dirt or residue stuck on them can be wiped off easily.
  • It is important not to use harsh materials when cleaning solar panels as they could cause damage.
  • Running a hose along the panels for dirt removal on a regular basis would be highly beneficial.
  • Avoid extremely high-pressure water sprayer when washing off your solar panels. A high-pressure attachment discharging water at pressures greater than 35 bar can damage the solar panels.
  • Stains which solidify and stick to the panel e.g. bird droppings, need to be removed at the earliest.
  • Do not overclean your system. Unless there is a significant amount of dust in your area, a weekly cleaning should suffice.
  • The best time for cleaning the panels is early morning or late evenings. During the peak hours, not only are the panels too hot, you may also lose significant generation. Also, if cleaned during peak hours, the glass becomes very hot, and spraying water on the hot glass can cause thermal stress and break/damage the glass eventually.
