The cost of photovoltaics has been cited as a primary barrier to widespread solar adoption for some time. Fortunately, those costs have dropped significantly in recent years, making solar more widely accessible to consumers and more cost-competitive as a wholesale resource across the country. The latest edition of the annual "Tracking the Sun" report from the Department of Energy's Lawrence Berkeley National Laboratory illuminates PV's changing cost dynamics, tracking national trends in installed costs as well as differences by region, system size and installation type. Join report co-author Galen Barbose for this SEIA webinar as he reviews the latest findings.
