12. Do not change the connection of bypass diodes to avoid the hazard of electric
shock and injury.
13. Max/Value - Series of modules qualified for Application class A
1.
PV modules are intended for outdoor use only and should be installed in a location
where they will receive maximum sunlight throughout the year.
2.
In Northern latitudes, the modules would normally face true south & in the
Southern Latitudes, the modules should face north for optimum power output
3.
Avoid trees, buildings or obstructions which could cast shadows on the solar
modules especially during the winter months when the arc of the sun is lowest over
the horizon.
4.
Solar modules produce maximum power when they are pointed directly at the sun.
5.
For installations where the solar modules are mounted to a permanent structure,
the solar modules should be tilted for optimum winter performance.
More sunlight per square foot falls on a perpendicular surface (90 deg to the sun’s ray is
optimal).Less sunlight falls on a vertical surface & horizontal surface.
The module tilt angle is measured between the solar modules and
the ground
