California utility PG&E has tested levels of residential solar power up to 100% penetration, and how to mitigate the effects of voltage and thermal overload via smart inverters and traditional transformer and circuit upgrades — with smart inverters shown to allow for up to 100% penetration at cost-effective pricing.
The state grid operator reported breaking 11 GW of instantaneous power from large scale solar on Saturday at 1.50pm. Just 20 minutes earlier, the CAISO grid was exporting a record 1.5 GW of electricity, and last Wednesday it hit 93% clean electricity for a moment.

The U.S. state’s latest report shows that it has beat its 2020 target for emissions reductions four years early, mostly thanks to more renewable energy.
A new study finds that from 2013 through 2015, distributed PV reduced peak solar hour mean wholesale electricity prices by 8–9%, avoiding costs of US$650–730 million.
A new poll by Morning Consult found surprisingly strong support for a California-style mandate across the political spectrum, although Liberals were more likely to favor the measure than Conservatives.
During May utility-scale solar provided 17% of generation on California’s grid, outpacing gas for the first time on a monthly basis.
