Tracking the Sun, 2018 Edition Webinar

October 4, 2018

A webinar summarizing key findings from the latest edition in Berkeley Lab’s annual "Tracking the Sun" report series. The report describes installed prices and other trends among distributed photovoltaic (PV) systems in the United States, based on an underlying dataset of more than 1.3 million PV systems (with transaction prices for 770,000 systems). This latest edition focuses primarily on trends through year-end 2017, with additional data for the first half of 2018. The report provides an overview of both long-term and more-recent trends, highlighting drivers for installed price declines over different time horizons. The report also extensively characterizes the widespread variability in system pricing, comparing installed prices across states, market segments, installers, and various system and technology characteristics.
