Why you should clean your solar panels

When it comes to solar panel cleaning, many people aren’t sure how to or how often. Normally the average bit of dust is washed away naturally by the rain. However, solar panels are exposed to harsh weather conditions and obscuring objects such as leaves, ash or bird droppings so cleaning and maintaining your system will help you make the most out of your investment. These obstructions will reduce your solar systems efficiency and ability to function at full capacity.


How often you should clean your solar panels

You should be frequently assessing how dirty our solar panels are and clean them as required. Whilst there is no hard and fast rule when it comes to cleaning frequency, All Energy HQ recommended that our customers clean their panels at least every 6 months to ensure each system is working at an optimum level. Factors such as location, weather conditions and the type of panel you have may impact how often dirt, grime and debris build up. 

Cleaning your solar panels at home

The best way to clean your solar panels at home

If you decide to clean your solar panels on your own, it’s important that you have the appropriate safety equipment required such as a harness. 

All Energy HQ recommends a simple cleaning solution made with water and a mild soap or cleaning agent specifically designed for solar panels. It’s important to use a soap broom or brush. Here’s a step by step:

  1. Rinse the panels with water to remove loose dirt and debris. 
  2. Mix a cleaning solution of water and mild soap, such as dish soap, or a specialised solar panel cleaning solution. 
  3. Apply the cleaning solution to the panels with a soft cloth or squeegee. 
  4. Use a soft-bristled brush to gently scrub away any stubborn dirt or debris. 
  5. Rinse the panels thoroughly with water to remove all cleaning solutions and soap residue. 
  6. Use a clean, soft cloth to dry the panels. 

What not to do

To avoid causing any damage to your panels or a reduction in their efficiency – here’s what not to do: 

  • Don’t use abrasive materials or chemicals: Scratches or damage to the panels can reduce their ability to absorb sunlight and generate electricity. Avoid using abrasive materials, such as scouring pads or wire brushes, and harsh chemicals that can damage the panels. 
  • Don’t clean the panels on a sunny day: Cleaning the panels when they are hot can cause the cleaning solution to evaporate too quickly, leaving streaks or residue on the panels. Clean the panels on a cloudy day or in the shade. 
  • Don’t use high-pressure hoses or gurneys: High-pressure water can cause damage to the panels and their seals, reducing their efficiency and potentially causing water damage to the electrical components. 
  • Don’t walk on the panels: Walking on the panels can cause physical damage, reducing their efficiency and potentially voiding the manufacturer’s warranty.
