Washing your panels could increase output by as much as 30%
Metro Solar recommend an annual service to get your panels clean and ensuring your system is working to its optimum. The most common time of year for this is Spring in preparation for the Summer.
If your panels are easy to reach, Metro Solar welcome you to wash the panels yourself to keep your production levels as high as possible.
Attached are the panel cleaning guides from JA Solar on how to clean their panels.
The simplest way is with washing up liquid and a squeegee.... wash the panels the same way as you would wash your windows.
Metro Solar includes a solar panel clean in its standard system servicing package, prices start at $299 ex GST
