Families of photovoltaic modules

Silicon, treated accordingly, ensures the existence of various families of photovoltaic modules:

Crystalline family

Monocrystalline silicon
Polycrystalline silicon

Main characteristics:

Smaller size
Efficiency equal to 12-16% (in specific measuring conditions)
Shade-sensitive

Thin-film

Amorphous silicon
Micromorph (Mcph)
Copper/indium/selenium (CIS o CIGS)
Cadmium tellurium (CdTe)

Main characteristics:

Larger sized
Efficiency equal to 5-6% (in specific measuring conditions)
Not shade-sensitive (produce energy even under a cloudy sky)
Does not require tilted modules
Are less affected by temperature
Make use of more daylight hours (begin producing energy earlier in the morning and end later in the evening)
Have a faster return on investment

Installation systems

Photovoltaic modules may be used with one of two different types of installation systems

Self-standing systems (Stand Alone)
These are systems that produce energy for self-consumption and do not provide for energy exchange with the power grid; hence, the energy produced during daylight hours cannot be recovered during the night;
Systems connected to the power grid (Grid Connected)
These are systems that produce energy for self-consumption and for exchange with the power grid; for this reason, this is the most commonly adopted system (in addition to the possibility of benefiting from government incentives).

Architecturally speaking, photovoltaic modules may be integrated into building architecture to a greater or lesser degree, to achieve structures similar to those indicated below:

Non-integrated architecture: Ground-standing systems.
Semi-integrated architecture: Systems on the rooftops or balconies of houses and buildings.
Integrated architecture: The modules substitute materials used to cover house and building rooftops, cantilever roofs and facades.
