Alternate Energy

Founded in 1993, Alternate Energy Inc. is one of Hawaii’s most experienced renewable energy companies, specializing in the design and installation of PV, HVAC, solar thermal, and energy storage. AEI’s HESS (home energy storage solution) is an intelligent, energy storage battery system that charges using electricity generated from solar panels, or when utility rates are low, then powers up your home for the cost it took to produce that energy on your roof – for free.
