Hawaiian Electric Co. approved 1,987 solar system applications on Oahu in the month of March.

The utility set out to approve a backlog of 2,749 systems waiting in October for approval in areas with high numbers of rooftop solar connected to the grid, saying the majority of those applicants would be approved by April and the remaining would be cleared by the end of 2015.

As of March 31, the utility had approved 2,543 of the applications.

Almost 80 percent of the applications approved were within the last month as the company’s monthly report to the Public Utilities Commission in February said there were 2,193 applications still pending approval.

There are 206 applications still waiting for approval on Oahu.

The utility announced in March all Maui Electric and Hawaii Electric Light customers who had been waiting in October were approved. There were 333 applications on Maui and 336 on Hawaii island waiting for approval.
