4. Maintenance and care
a) A built up of dust or dirt on the module(s) front face will result in a decreased energy
output. Clean the panel(s) preferably once per annum if possible (depend on site
conditions) using a soft cloth dry or damp, as necessary.
b) Never use abrasive material under any circumstances.
c) Examine the PV module(s) for signs of deterioration. Check all wiring for possible rodent
damage, weathering and that all connections are tight and corrosion free. Check electrical
leakage to ground.
d) Check fixing screws and mounting brackets are tight, adjust and tighten as necessary.
e) When clean the modules, it is not allowed to stand on the module or the likes. Like below
pictures show, this it prohibited.
5. Electrical specification
The module electrical rating is measured under Standard Test Conditions, which are
1000W/m2, irradiance with AM 1.5 spectrum and 25 deg (77°F) ambient temperature. The
module might produce more or less voltage or current than rating value in uncertainty
condition. Accordingly, the values of I
SC
and V
OC
marked on this module should be multiplied
by a factor of 1.25 when determining component voltage ratings, conductor current ratings,
fuse sizes,
and size of controls connected to the PV output. Tables below are electrical characteristics
of PV products at STC and the tolerance of Isc
