Distributed Generation

Solar Energy is a form of ‘Distributed Generation.’  Distributed generation refers to the small-scale production of electricity on a local level, rather than large-scale industrial power plants.  This is factor of vital importance because centralized energy production creates situations where

History of Photovoltaics

History of Photovoltaics: The French physicist A. E. Becquerel first observed the photovoltaic effect in 1839. The photovoltaic effect is the creation of electrical voltage and current when a material is exposed to photons from the sun.  “Photovoltaics (PV) is a method of generating electrical power by
