Rooftop photovoltaic power station Rooftop photovoltaic power station A rooftop photovoltaic power station, or rooftop PV system, is a photovoltaic system that has its electricity-generating solar panels mounted on the rooftop of a residential or commercial building or structure. The various components of such a system include photovoltaic modules, mounting systems, cables, solar inverters and other electrical accessories. Rooftop mounted systems are small compared to ground-mounted photovoltaic power stations with capacities in the megawatt range. Rooftop PV systems on residential buildings typically feature a capacity of about 5 to 20 kilowatts (kW), while those mounted on commercial buildings often reach 100 kilowatts or more.
Module file known as tracking, is a skillful activity that involves a much closer contact with musical sound than conventional composition, as every aspect of each sonic event is coded, from pitch and duration to exact volume, panning, and laying in numerous effects such as echo, tremolo and fades. Once the module file is finished, it is released to the tracker community. The composer uploads the new composition to one or more of several sites where module files are archived, making it available to his or her audience, who will download the file on their own computers.
