In 1989, the German Research Ministry initiated the first ever program to finance PV roofs (2200 roofs). A program led by Walter Sandtner in Bonn, Germany.In 1994, Japan followed in their footsteps and conducted a similar program with 539 residential PV systems.
Overall the manufacturing process of creating solar photovoltaics is simple in that it does not require the culmination of many complex or moving parts. Because of the solid-state nature of PV systems, they often have relatively long lifetimes, anywhere from 10 to 30.
Solar photovoltaics formed the largest body of research among the seven sustainable energy types examined in a global study, with the annual scientific output growing from 9,094 publications in 2011 to 14,447 publications in 2019.
