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.
Support of a module of the vanishing locus of the polynomial. However, since formula_33 is an integral domain, the ideal formula_28 is isomorphic to formula_33 as a module, so its support is the entire space. The support of a module is always closed under specialization. Now, if we take two polynomials formula_36 in an integral domain which form a complete intersection ideal formula_37, the tensor property shows us that Support of a module In commutative algebra, the support of a module "M" over a commutative ring "A" is the set of all prime ideals formula_1 of "A" such that formula_2. It is denoted by
