.
Installing Solar Panels to suitable place.
Installing the solar panels of the SGPV to suitable location that sunshine can irradiate on
them, there must have no shadow, the installation direction of the solar panels should be
according to the geography position that the system will be installed, different position should
has different installation direction, the principle is to get maximum irradation in all the year
round.
Warning: Ensure that there is no shadow at the location that solar panels will be installed,
because even the shadow just covers only one cell of solar panel, maybe will cause total
system stop to produce power.
Warning: Ensure using strong braket to fix the solar panels to avoid the danger under
high wind.
Step6.
sunlight, high
temperatures, and water. The inverter requires at least 150mm of clearance around itself for
ventilation. The inverters are for indoor use, can’t use at outdoor. You can use screws to fix
tie inverter have fans on
the bottom cover, so the surface should be flat.
Step7.
After finished from Step1 to Step6, you should connect the solar panels and inverters with cables
Step8.
Grounding the system.
Route a continuous GEC through each of the solar panels to the NEC approved AC grounding
electrode. The racking and module could be grounded to this conductor using a crimp
connection. An alternative method would be to connect the grid tie inverters to the grounded
racking using a grounding washer approved for the racking. The ground wire of the AC cables
is connnected to the housing of inverter when the AC cables is connected to the inverters, so
when the AC plug is inserted to the socket of AC outlet of utility grid in the house, the ground pin
of the socket must be connected to the Earth ground.
Step9.
Connecting the PV modules after complete from Step1 to Step8.
Warning:
If you will connect the PV modules to the inverter under sunshine, you should cover
the modules with no transparent material like black cloth, if the modules have been connected in
serial, just cover one module, actually, just need to cover one cell of the module, but if the
modules have been connected in parallel, you should cover one module of every branch, also
just need to cover one cell when you cover a module.
Covering the modules under sunshine just in order to avoid the sparkle when connect the cables.
