Abstract: A photovoltaic mount can include a groove to receive a plurality of photovoltaic panels spaced by seismic gaps, a wall coupled to a structural framing channel, and modular connecting devices to couple the plurality of photovoltaic panels to portions of the groove. The photovoltaic mount can be fabricated away from a power generation site. A modular photovoltaic system can include a plurality of prefabricated intermediate modules, each having photovoltaic panels modularly secured thereon, and a prefabricated termination module having photovoltaic panels modularly secured thereon. The modular photovoltaic system can be assembled at a power generation site while the prefabricated intermediate and termination modules can be fabricated away from the power generation site. A photovoltaic power generating center can include a composite arrangement of modular photovoltaic systems. Also disclosed are related methods.
