Hawaii’s electricity prices are the highest in the nation and the state is getting heavily into solar power. On Oahu, where most of the state’s population resides, over 12 percent of electric utility customers have rooftop solar systems, which is about 20 times larger than the solar penetration rate of any utility on the mainland. Many of these solar homes have zero electric bills, which is causing problems for the electric utility company that must provide power to the other residents and maintain the power lines that the solar power uses without charge.(i]
