Normal photovoltaic systems however have only one p–n junction and are therefore subject to a lower efficiency limit, called the "ultimate efficiency" by Shockley and Queisser. Photons with an energy below the band gap of the absorber material cannot generate an electron-hole pair, so their energy is not converted to useful output, and only generates …

A solar charge controller, also known as ''charge regulator'' or solar battery maintainer, is a device that manages the charging and discharging of the solar battery bank in a solar panel system. Preventing the battery from overcharging is important merely because the voltage generated by even a 12V solar panel is actually higher – between 16 and 20V.
Chapter 1: What is a solar charge controller? A solar charge controller, or solar charge regulator, is an important instrument in almost all solar power systems that use batteries as a chemical energy storage solution. It is used in stand-alone or hybrid solar power systems but not used in straight grid-tied systems, which don''t have rechargeable …
