The Global Solar Power Tracker is a worldwide dataset of utility-scale solar photovoltaic (PV) and solar thermal facilities. It covers all operating solar farm phases with capacities of 1 megawatt (MW) or more and all announced, pre-construction, construction, and shelved projects with capacities greater than 20 MW. Some data are also included for plants that are either mothballed, retired, or cancelled. For more information about inclusion criteria, please see our Methodology page. A solar project phase is generally defined as a group of one or more solar units that are installed under one permit, one power purchase agreement, and typically come online at the same time. Each solar farm included in the tracker is linked to a wiki page on the GEM wiki.
