Operation and maintenance
Carry out regular inspection and maintenance for modules and this
is the user’ responsibility
within the quality warranty period in particular; and, inform the supplier within two weeks when
modules are found to be damaged.
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. DualSun suggests that the module surface should not be
sheltered in any case.
Frequency of cleaning depends on dirt accumulation speed. In normal situations, rainwater will
clean the module surface and the cleaning frequency is reduced therefore. It is suggested to use
damp clean water sponge or soft cloth to wipe the glass surface. Do not use acid and alkaline
detergents to clean modules.
