8.1 Cleaning
Accumulated dust on module surface glass will reduce the power output and lead
to local heat spot, such as industrial waste water and birds droppings. The degree
of influence is determined by transparency of wastes. Small amounts of dust will
affect sunlight strength and evenness but are not dangerous and power will not be
reduced remarkably in general.
During operation of modules, there shall be no environmental factors projecting
shades or shelter partial or the entire module, including other modules, module
system bracket, birds, dust, soil or plants. These will reduce output power.
GRUPPOSTG suggests that the module surface should not be sheltered in any
case.
