module is not allowed to withstand additional
external force.
d) During cleaning, it is strictly forbidden
to step on the modules, splashing water to
the back of the modules or cables. Ensure
that connectors are clean and dry to prevent
electric shock and fire hazard. Steam clean
machines are strictly prohibited; soft parts,
Cloth and mild detergent and water should
be used. Do not put modules directly into the
water. Serious thermal shocks also could
damage modules.
e) The difficult-to-clean substances
such as oil on the surface of modules, use
a non-friction neutral liquid cleaner. Do not
use any organic solvent containing alkali or
acid. Do not use corrosive solvents or wipe
the PV modules with a hard object.
f) If you are not sure whether the array
need to cleaned, first select a column of
particularly dirty array to begin cleaning. If
the power generated increased less than 5%,
cleaning is usually not required. The above

Cover the front surface of Modules with an
opaque material. Modules exposed under the sun
could be extremely dangerous, as high voltages
could be generated.
6.1.6
Module junction boxes is equipped with bypass
diodes to minimize module heating and current loss
to be replaced. Module must be replaced
with same type one. Do not touch the live
parts of the cables or connectors when
replacing modules. Use appropriate safety
guards (insulation tools, insulated gloves,
insulated boots, etc.) when handling modules.
