6. Maintenance and care

In general it is not necessary to clean the modules if the inclination is >10°. In case of persistent

dirt use only classic glass cleaner or cleaning alcohol. Do not use galling or chemical cleaners, do

not scrape the module.

All modules are maintenance free, but it could be useful to verify the PV-installation regularly

against following criteria's:

Integrity of the cables

Fastening elements against e.g. loose brackets

Cleanness, stainlessness and safe connection of all cables connections

In some cases:-

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 this it prohibited.

The module electrical rating are 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 ISC and VOC 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. Please refer DuSol catalogue for more electrical

characteristics of PV products at STC and the tolerance of Isc,Voc,Vmp and Imp is+15% & -5%.
