One of the best resources for tracking trends in the solar industry was just released. The recently published annual Tracking the Sun report from Lawrence Berkeley National Lab (LBNL) describes price and technology trends for distributed solar projects nationally, collecting project-level data from approximately 1.6 million systems through the end of 2018. The latest edition of the report, which is now in its twelfth year, finds that prices for distributed solar power systems continued to fall in 2018, that industry practices continue to evolve, and that systems are getting bigger and more efficient.
