Hawaiian Islands’ solar installations doubled in 2010
It was a year of unprecedented growth in Hawaii as the number of installed, customer-cited solar arrays on Oahu, Hawaii Island and Maui County more than doubled from 2009 to 2010. According to the Hawaiian Electric Co., the number of solar arrays grew to 3,967 at the end of 2010, compared to 1,916 at the…
It was a year of unprecedented growth in Hawaii as the number of installed, customer-cited solar arrays on Oahu, Hawaii Island and Maui County more than doubled from 2009 to 2010. According to the Hawaiian Electric Co., the number of solar arrays grew to 3,967 at the end of 2010, compared to 1,916 at the end of 2009.
“Interest in solar power has steadily increased in recent years, but it really took off in 2010,” Robbie Alm, Hawaiian Electric executive vice president, said in a press release announcing the solar growth.
Hawaiian Electric said the systems it counted included net-metered systems and those under standard interconnection agreements with the utility.
“Interest in net energy metering started to increase in 2008, when crude oil prices spiked at $147 a barrel,” the company said.
Darrek Fujikami, solar energy specialist with the Hawaii Department of Business Economic Development and Tourism, said the growth can be attributed to three factors. I think part of it is the public understanding the programs that are out there, that everyone wants to go green, and we have tax incentives. It’s a combination of all three,” he said.
Electric prices in Hawaii are high because most of its generation now comes from petroleum-based generators, and it has to be imported via ships. As of October 2010, the average price for electricity at 28.5 cents per kilowatt hour was more than double the average U.S. price at 11.93 cents per kilowatt hour, according to the Department of Energy’s Energy Information Administration.
With the high cost of utility-supplied electric generation, full payback of a solar installation can be achieved in Hawaii within five to six years, Fujikami said.
The state also has the nation’s highest renewable energy standard, which will require utilities to source 40 percent of the electricity they produce from renewable sources like wind and solar by 2030.
Although Fujikami didn’t have predictions for the growth of solar in 2011, he said it will continue to grow.
