With fantastic solar insolation and high electricity prices due to a dependence on imported energy, Hawaii is an ideal solar market. However, interconnection continues to be an issue as Hawaiian utilities have imposed restrictions to avoid solar generators' loads on their systems.
The Hawaii State Capitol, located in downtown Honolulu, houses the
executive and legislative branches of the state government.
