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
Galois module is only with respect to the discrete topology on "V", thus making the situation more algebraic in flavor. Galois module In mathematics, a Galois module is a "G"-module, with "G" being the Galois group of some extension of fields. The term Galois representation is frequently used when the "G"-module is a vector space over a field or a free module over a ring, but can also be used as a synonym for "G"-module. The study of Galois modules for extensions of local or global fields is an important tool in number theory. Let "K" be a valued field (with valuation
