Maui Electric Co. nets 66 megawatts of residential rooftop solar, second best among the counties served by its parent company, Hawaiian Electric Cos.

Oahu garners 289 MW of rooftop solar and Hawaii island 63 MW, according to a Hawaiian Electric report released Wednesday.

There were 11,414 residential solar systems in Maui County, which produced 19 percent of MECO’s power in 2018, tied with Oahu percentage wise. The photovoltaic systems’ output for Maui County was 1 percentage point higher than 2017.

Rooftop solar systems installed by Hawaiian Electric customers increased 5.3 percent, from 70,607 in 2017 to 74,331, in 2018, which continues Hawaii’s standing as the No. 1 state for private rooftop solar, the electric company said. Nearly 4,000 new systems came online last year, providing 18 percent of power in HECO’s tri-county system.

Connecticut is the second highest for private rooftop solar at 6.8 percent; California is third at 5.9 percent; Arizona has 4.5 percent; and Utah and Massachusetts have 3.4 percent, according to the Smart Electric Power Alliance.
