MAINTENANCE OF THE PHOTOVOLTAIC GENERATOR
The photovoltaic modules require operations of maintenance limited.
The circuit inside of the cells and the welds of connection are in fact isolated from the environment external by
means of layers of material protective and the own structure it is devoid of pieces furniture.
The operation of maintenance consists of:
Periodic cleaning of the modules.
Visual inspection of the modules.
Control of electrical connections and the wiring.
Periodic cleaning of the modules
The dirt accumulated on the cover transparent (e.g. residues industrial and material of rejection of
birds) of the modules can cause reversal of similar effects to those produced by shadows, reducing its
performance.
A second of the conditions environmental, a degree of dirt more or less high can lead to a reduction of
the generated energy . The intensity of the effect depends on the opacity of the residue.
The layers of dust that reduce the intensity of the sun in so uniform not are dangerous and the
reduction of power not has, in general, significant.
The periodicity of the process of cleaning depends, logically, the intensity of the process of soiling. The
action of rain can, in many cases, minimize or eliminate the need for cleaning the modules.
Wash the modules photovoltaic with water with a temperature adapted to that of the module
GruppoSTG Fabbrica Srl using one rag or a sponge soft, avoiding the accumulation of water on modules
photovoltaic.
In any case, you can use machinery to pressure.
If necessary, use a mild liquid detergent . Do not use never detergents containing agents abrasive..
