Earlier today, David Roberts of Vox posted on two new reports by Lawrence Berkelely National Laboratory (LBNL): 1) Utility-Scale Solar 2015: An Empirical Analysis of Project Cost, Performance and Pricing Trends in the United States and 2) Tracking the Sun IX: The Installed Price of Residential and Non-Residential Photovoltaic Systems in the United States. As Roberts notes, solar power is "growing growing growing" as prices fall "more or less on schedule" vis-a-vis the SunShot Initiative's ambitious goal of $1 per watt installed cost by 2020.
