Module mounting structure
PV modules are designed to be installed outdoors without additional protection. A mounting structure must be
constructed to support the modules in all weather conditions. The PV array should be mounted so as to take full
advantage of the sunlight. In the northern hemisphere, it should face south; true south is best, depending on the
latitude of installation the deviation from true south will have a an effect on the radiation received on the tilted
plane of the modules and hence on the energy production. Very large installations can be mounted to track the
sun either automatically or manually. In most cases, the mounting is fixed at one angle (a right angle to the sun
at noon), but can be adjusted according to the season. Select a site where the solar module will not be shaded
at any point during the day sunshine hours. PV module can be mounted on a roof/ ground. Refer as for Module

PV Module Interconnection
PV Module are connected in series / Parallel as below. In two modules are connected series and 2 strings are in
parallel.
