Cleaning and maintenance of PV module
Crane Ltd modules are manufactured as this to have prolonged service life and require minimal
maintenance.
You should regularly remove accumulated dirt from the PV module(s) (eg dust, pollen,
vegetation, bird droppings, etc.). Such contamination, which overshadows the modules' active
areas can lead to limitation of system performance and decrease the solar pump production.
Please obcerve the following points:
For PV module(s) cleaning use water and soft sponge.
Avoid the water cleaning, when there is a danger of freezing of big temperature
differences between the module, the water and the air.
Hard water used for the cleaning, must be descaler in advance, so the remaining traces
to be avoided. Remove the remaining water from the module.
Do not use abrasive cleaning materials or surface-active agents (eg. Soap). Do
not scrap the contaminations. This might damage the modules' surface.
VII. Protection of the environment
After the service life termination of the solar pump, do not dispose it with normal
household waste, but transmit it to a collection point for waste recycling. This will
help protect the environment.
