Hawaii Energy, the state's energy conservation and efficiency program, has increased its instant rebate on new, qualifying residential solar water heating systems from $750 to $1,000. The new rebate is expected to be available only for a limited time.
A typical household of four or more that switches to a solar water heater can save up to 40% – about $600 a year – on its electric bill, according to Hawaii Energy. The $1,000 instant rebate, combined with applicable state and federal tax credits, reduces the cost of the average solar water heating system from approximately $6,600 to about $2,000.
