Solar panel maintenance is often regarded as unnecessary customers often believe that as the panels are out on a roof then they are virtually self-cleaning.
This is a misconception.
There are many external influences which can contribute to solar panels becoming obstructed and lead to inefficient production.
Road grime, dust, salt spray and bird droppings are just a few, left uncleaned, these can cause a higher degradation rate to your system.
Solar panels laying on a flat roof are more susceptible to build up of grime and require more regular cleaning.
