One of the advantages of photovoltaic (PV) energy is that it is inherently modular. Unlike many other energy sources, it allows the implementation of small-, medium- and large-scale generation systems, ranging from portable and rooftop systems to large multi-megawatt PV farms. System requirements, performance specifications, regulations, and even the economics behind the different system sizes, […]
