Rooftop solar and battery storage on Hawaiian Electric grids reach historic milestone

Excerpt from mauinow.com

Hawaiian Electric announced today that customer-sited rooftop solar and battery storage connected to its grids have surpassed 1 gigawatt of generating capacity — the equivalent of about 100 million LED lightbulbs.

The achievement comes about 25 years after the company launched its first solar programs and began addressing the technical challenges of integrating large amounts of intermittent solar energy. Today, Hawaiian Electric’s service area has one of the highest rooftop solar adoption rates in the nation, with an estimated 44% of single-family homes equipped with solar systems.

Helped by steady customer demand, the rated capacity of rooftop solar systems and battery storage has more than doubled over the past 10 years.
