Issued solar permits in Hawaii declined last year

Hawaii is issuing less solar permits since the drop of its net energy metering program

In 2017, the number of issued solar permits in Hawaii’s largest solar market – Oahu – dropped by 34% from the previous year, only reaching 2,993.

4,591 PV system permits were issued in 2016, whilst in 2015, the number hit 7,493 – 60% higher than last year’s figure.

According to data released by Marco Mangelsdorf, the President of ProVision Solar, 2017’s permits are 82% lower than Oahu’s record, set in 2012, of 16,715 issued permits.

Other Hawaiian islands also saw solar drop last year – Big Island’s number fell from 1,256 permits in 2016 to just 906 last year, a 28% decrease.


Maui’s figures fell more than half, dropping 59% from 2016’s 1,657 permits issued to 676 in 2017.

“Hawaii rooftop PV peaked in 2012-2013 and has been losing solar steam ever since,” Mangelsdorf stated.

“With the elimination of NEM by our PUC in October 2015, one of the main incentives to go PV has been diminished as lesser attractive interconnect programs (Customer Grid Supply and Customer Self Supply) were introduced.”

The disinterest in solar permits in the state follows the conclusion of Hawaii’s net energy metering (NEM) program for Hawaiian Electric Co. utilities.

Hawaii Public Utilities Commission ended the program in order to transition into a new renewabl market.
