U.S. Residential Distributed Solar: still getting cheaper, installation and permitting too, more batteries

October 20, 2022 by John Rogers

John Rogers at UCS reviews the new and comprehensive “Tracking the Sun” report from Lawrence Berkeley National Laboratory which covers both residential and non-residential “grid-connected, distributed” solar PV systems in the U.S. There has been clear progress across the board, including PV module efficiency, system costs, installation and permitting, and the uptake of batteries. For example, median efficiency for modules in residential systems … [Read more...]

What’s best? Building Solar panels that last 30 years, or are short-lived easy-to-recycle and upgrade

April 27, 2022 by Harrison Dreves

The good news is that PV modules last so long – 30 years – that we don’t have to worry about recycling for a while. The bad news is that means we’re not thinking about the alternative pathway of deliberately building modules that last only a few years yet can be easily recycled and improved. Harrison Dreves at NREL describes the data-gathering and creation of a modelling tool that quantifies the flow of materials, energy, and carbon in the PV … [Read more...]
