Harnessing the Power of Light

HNU Energy, a Maui-based complete energy solution provider and engineering firm, offers renewable energy generation, energy storage, and high-efficiency lighting products for all types of residential and commercial customers.


The company name derives from the formula defining the energy contained in one photon of light: each photon possesses energy equal to Planck’s constant (h) multiplied by its frequency ν (a Greek letter nu pronounced “new”). In plain English HNU is the ENERGY of LIGHT!
