The connectors at the opposite end of these wires allow easy series connection of
adjacent modules by firmly inserting the male connector of a module into the female
connector of an adjacent module until the connector is fully seated.
For a series electrical connection, should connect positive (+) connector of the first
module to the negative (-) connector of the following module. For a parallel electrical
connection, should connect positive (+) connector of the first module to the positive (+)
connector of the following module.
The cable typically used to interconnect the modules should be stranded or solid copper
single-conductor type, rated sunlight resistant, for modules and module wiring that is
exposed to weather, from 12AWG (4.0mm
2
) up to 14AWG(2.5mm
2
) gauge copper wire.
The maximum and minimum diameters of the cable that may be used with the cable
connector are 8mm and 6mm respectively. A separate return wire or wires may be
required to run the positive and negative terminations of the series string of modules to
the load. Male and/or female connectors pre-attached to wires may be used at the string
terminations for return wire connections and/or for source circuit box terminations.
Modules have bypass diode(s) installed.
VII) MAINTENANES
It is not uncommon for a remote site to be checked but once per year. Under most
conditions, normal rainfall is sufficient to keep the module glass clean.
Clean the glass with a soft cloth using mild detergent and water. Modules that are
mounted, fiat ( 0°tilt angle) should be cleaned more often, as they will not self-clean as
effectively as modules mounted at a 15°tilt or greater.
It is advisable to perform periodic inspection of the modules for damage to glass,
backskin, frame and support structure. Check electrical connections for loose
connections and corrosion. Check if mounting support structure and modules are loose.
Check connections of cables, connectors, and grounding. Change modules must be the
same kind and type, if need. Modules can operate effectively without ever being washed,
although removal of dirt from the front glass can increase output. The glass can be
washed with a wet sponge or cloth, wear rubber gloves for electrical insulation.
VIII) SAFETY PRECAUTIONS
Module installation and operation should be performed by qualified personnel only.
Children should not be allowed near the solar electric installation.
Avoid electrical hazards when installing, wiring, operating and maintaining the module.
Modules produce DC electricity when exposed to light and therefore can produce an
electrical shock or burn. Modules produce voltage even when not connected to an
electrical circuit or load. Modules produce nearly full voltage when exposed to as little as
5% of full sunlight and both current and power increase with light intensity. Do not touch
