California is learning to trust 100% residential solar power

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% penetrations at cost-effective pricing.

It’s all about the efficiency

An analysis by mono PV maker LONGi shows the math on how increases in module efficiencies drive down balance of system costs.
