Cleaning; Inspection Of Connector And Cable; Electrical Specification - Jinko Solar JKM M-72 Series Installation Manual

4.2 Cleaning

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. Water
with high mineral content may leave deposits on the glass surface and is not
recommended.
b) Never use abrasive material under any circumstances.
c) In order to reduce the potential for electrical and thermal shock, Jinko
recommends cleaning PV modules during early morning or late afternoon hours
when solar radiation is low and the modules are cooler, especially in regions
with hotter temperatures.
d) Never attempt to clean a PV module with broken glass or other signs of
exposed wiring, as this presents a shock hazard.

4.3 Inspection of Connector and Cable

It‟s recommended to implement the following preventive maintenance every 6
months:
a) Check the sealing gels of the junction box to ensure it have no crack or crevice.
b) 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.

5. Electrical specification

The module electrical rating are measured under Standard Test Conditions, which
2
are 1000W/m , 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.
