Today’s solar technology is so advanced that it is difficult to find a reason not to invest in it for your own home. According to the clean energy council, Australian homes with rooftop solar tops over 2 million installs. The electricity generated can lead to a significant reduction in electricity costs.

Solar panels are usually very durable and do not require much maintenance, so their management is relatively simple. But solar panels can lose 15-25% of their efficiency if not cleaned properly. Here is a guide on how to maintain a residential solar system.

Prepare tools:

  1. Soap. (Standard detergent works. Any soap that doesn’t leave a residue)
  2. Scrubbing brush (preferably with a long handle or extendable handle)
  3. Hose with a sprayer
  4. Window wiper or a microfiber cloth

First, you need to decide if your solar panels need cleaning. It might be time to clean solar panels if you find them covered with dirt. Before cleaning, check with the manufacturer to determine if there is an individual instruction to cleaning the panels.

Second, remove large debris if you find any on the solar panels. You can use a brush to remove them. Dip a scrub brush into the soapy water and start gently scrubbing the solar panels. Please note not to scrub too hard on the surface because it can leave micro-scratches on the surface of the solar panels.

Third, rinse off soapy water on the solar panels with a hose. It is essential to use a sprayer hose and not a pressure hose. High pressure can cause damage to the solar panels. Once all soapy water is removed, dry the solar panels with a window wiper or a microfiber cloth.

Finally, make sure the solar panels are dried thoroughly, and there is no residue left. The reason is that residue can create a thin film that blocks sunlight entering solar panels. So it is essential to ensure there is no residue.

You can check the result of the cleaning by monitoring the energy output of the solar panel. You should see an increase in energy output. If there is no increase in energy output, there might be some residual left on the solar panel. You can monitor the energy output for when it’s time to clean again next.

Now that you know how to clean your solar system and how it works, your solar panelscan produce electricity at the highest level.
