Solar Panel Cleaning Service

Solar Panel Cleaning can Save you Money

There are many issues that come with dirty solar panels. In some parts of the UK, domestic solar panels won't need cleaning due to the heavy amount of rainfall. However, agricultural solar panels and commercial solar need to be cleaned by professional solar panel cleaners. 

A build up of dirt, moss, and bird droppings can severely impact the production capabilities of your solar panels. Even the smallest bird droppings can cause shade which will be detrimental to your solar panel effeciency. Hard water can also affect your solar output. A loss of production on your commercial solar powering will affect payback time and reduce savings and earning potential. We want you to save as much money as possible from the second of solar installation. 

To keep your solar PV system working as effectively as possible we recommend that your commercial, industrial or agricultural solar panels should be cleaned every 6-12 months depending upon their environment. The absolute maximum without cleaning should be 2 years.  As 75% of the year’s production is between April and September, we recommend cleaning your panels between mid January and the end of March. Making sure you keep on top of Solar PV monitoring will ensure you don't miss your cleaning schedule.

You might have arrived here asking who will clean my solar panels? Mypower offer a competitively priced panel cleaning service for all makes of PV modules. At the head of the solar industry, Mypower use the state of the art Karcher rotary brush to clean. We use deionised hot water and no chemicals or cleaning products (as recommended by panel manufacturers for panel cleaning). The Karcher rotary brush is 50% more effective at cleaning solar panels compared to standard mop, brush, or cloth. When cleaning solar, many people will only clean the bulk of the glass. However, a rotary brush is able to get into the panel edges where algae, dirt, and diodes are located.

It is extremely important that solar panel cleaning is undertaken by a qualified panel installer. Solar pv panels can be easily damaged if stood or lent on. Too much downward pressure on them will cause invisible micro cracks which will significantly decrease yield. Do not under any circumstances use a pressure washer as this will damage the solar panels.

Did you know?

In April 2017 we completed a before and after study into how panel cleaning can increase solar energy output. The results showed a massive 9.6% increase in output following a clean…

  • The customer’s site had 168 solar panels connected identically to 2 inverters.
  • The mounted solar panels had been cleaned 12 months prior, so only 1 year of dirt build up was present.

  • Readings were taken for 7 days and 30 days prior to the test to establish any difference in output between the inverters.

  • The 84 panels connected to inverter 1 were identified as rows 1 to 4 of 8. These 4 rows were cleaned by our professional solar panel cleaners and the 84 panels on rows 5 to 8 were left dirty.

  • 2 weeks later, readings were taken again.

  • Inverter 1 with the clean solar panels produced 9.6% more electricity compared to inverter 2 with the dirty panels over the 2 week period.

  • The remaining 84 panels were then cleaned.

This data is consistent with the previous year’s findings of an 8.7% increase in yield when the same trial was carried out but with only 5 days between cleans.

The image clearly shows a difference of solar powering between the cleaned
panels in rows one to four and the uncleaned panels in rows five to eight

Not cleaning your solar panels can have a huge detriment to their solar energy output. For advice and competitive solar quotes please give us a call on 01242 620894 or email info@mypoweruk.com
