The OpenPV web site is no longer available but distributed PV installation data can be obtained from the Lawrence Berkeley National Laboratory's Tracking the Sun report.

OpenPV was a real-time tracker of cost-per-watt for distributed photovoltaic (PV) installations. The Tracking the Sun report is an annual effort that collects data from installers and other PV organizations, and can be used to identify the general locations and attributes of new distributed PV installations.
