What is a PV module?
A photovoltaic module is typically a group of solar cells assembled in a commercial unit ready for installation in a system. It is the form in which most power systems are purchased. Usually the PV module has a specified power rating and guaranteed lifetime (commonly ~20 years).

Highlights: In 1839, Edmund Becquerel of the famous French physicist family, discovered the photovoltaic effect. The material used was copper oxide in an electrolyte. In the 1860’s, Willoughby Smith discovered the photoconductive properties of selenium. In the 1870’s, W.G. Adams and R.E. Day investigated the photovoltaic properties of selenium. In 1874, Charles Fritts made the first solar cell from selenium and gold. The efficiency was less than 1%. In 1887, H. H
