History and acknowledgement

pvlib python started out as a Python translation of the PVLIB MATLAB toolbox (developed by the PVPMC at Sandia National Laboratories) in 2013 and has grown substantially since then. Today it contains code contributions from over a hundred individuals worldwide and is maintained by a core group of PV modelers from a variety of institutions.

pvlib has been supported directly and indirectly by DOE, NumFOCUS, and Google Summer of Code funding, university research projects, companies that allow their employees to contribute, and from personal time.
