Japan Photovoltaic Energy Association Japan Photovoltaic Energy Association Japan Photovoltaic Energy Association (JPEA) is the best-known body for solar photovoltaic energy companies in Japan. Founded on April 23, 1987, it has a number of objectives and activities, one of which is providing the JPEC certification for solar modules in the Japanese market. The association serves as a spokesperson for the photovoltaics energy industry in Japan. JPEA set a pathway for the photovoltaic industry in Japan to reach 100 GW by 2030, from roughly 30 GW in 2015. The group comprises multiple companies in the industry, and reported a 13% drop in total photovoltaic solar
Generating set of a module minimal if no proper subset of the set generates the module. If "R" is a field, then it is the same thing as a basis. Unless the module is finitely-generated, there may exist no minimal generating set. The cardinality of a minimal generating set need not be an invariant of the module; Z is generated as a principal ideal by 1, but it is also generated by, say, a minimal generating set }. What is uniquely determined by a module is the infimum of the numbers of the generators of the module. Let "R" be a local ring with maximal
