HONOLULU (HawaiiNewsNow) - The island's limit on rooftop solar systems that export energy to the grid has nearly been reached, Hawaiian Electric Co. said Thursday.
The Public Utilities Commission set the limit, while also making other changes.
HECO said customers should still pursue solar for their own energy needs.
"Non-export systems," HECO said, allow households to generate their own electricity and potentially store energy for use after the sun goes down.
Two such systems have been installed on Oahu, and 20 more are approved for installation.
"This is the next evolution in solar energy systems," said Jim Alberts, Hawaiian Electric senior vice president for customer service, in a news release.
"Solar power is a significant part of our plans to reach 100 percent renewable energy and an important option for our customers and we expect more customers will install self-supply systems."
