Photovoltaic system and is typically less useful than a calculation of return on investment. While it is typically calculated to be between 10 and 20 years, the financial payback period can be far shorter with incentives. Due to the low voltage of an individual solar cell (typically ca. 0.5V), several cells are wired "(also see copper used in PV systems)" in series in the manufacture of a "laminate". The laminate is assembled into a protective weatherproof enclosure, thus making a photovoltaic module or solar panel. Modules may then be strung together into a photovoltaic array. In 2012, solar panels available for consumers
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
