Founded in 1993 by the Ekimura family, Alternate Energy, Inc. has been growing slowly and steadily for more than 20 years, becoming a frontrunner in Hawaii’s renewable energy revolution. AEI is driven by the knowledge that more renewable and energy efficiency installations, like solar means less dependence on expensive oil and electricity. Solar allows Hawaii families and businesses to keep more of their hard-earned dollars.  All of our installers are AEI employees, not subcontractors. AEI takes full responsibility for every installation, no matter how large or small. We purchase high quality materials and systems direct from the manufacturer. Without a middleman, we can pass savings on to our customers.  Today, we are one of Hawaii’s oldest residential and commercial solar energy companies, locally owned and operated from day one. As always, we will continue to focus on what we do best: designing and installing photovoltaic systems, HVAC systems, solar water heating systems, and solar attic fans.
