Recurring power grid faults are testing solar inverter reactions, and have exposed issues that could seemingly be solved by improvements to commissioning, operations, and maintenance.

The decision has been lauded as one that could lead to much-needed upgrades to the nation’s electrical grids, updates that would enable higher penetrations of renewable resources.

The US DOE released a Memorandum of Understanding that aims to bring together parties to advance bi-directional charging with cybersecurity as a core component.

Of the 56 cities surveyed in all eight editions of the Shining Cities report, 15 recorded a tenfold increase in their solar capacity between 2014 and 2022, yet there is still much untapped potential.

While Neil’s concerns are warranted, there are reasons to be hopeful that we will be able to responsibly and profitably manage solar panel recycling as the volumes scale.
