●
The installation of project must be facing north in the southern hemisphere, and facing south in the
northern hemisphere, the electricity will be comparatively lower when the project facing west or east.
The incorrect installation will lead to the loss of power
●
The modules, which are connected in series, must be in the same angle, otherwise, it will lose power
because of the difference in sunlight intensity. Solar modules generate the power to the maximum when
they are pointed directly at the sun. For installations where the solar modules are mounted to a
permanent structure, the solar modules should be tilted for optimum winter performance. As a rule, if
the system power output is adequate in the winter, it will be satisfactory during the rest of the year. The
module tilt angle is measured between the solar modules and the ground.
●
Avoid installing under the shadow, even the module factory use the bypass diode to decrease the loss of
energy, the shadow will lead to the loss of output power.
4、
Grounding
●
All module frames must be attached to an earth ground. A qualified electrician must do the ground
connection .The cable which connects the earth must be copper wire with 12AWG.
