ABOUT US
Serving the Community Since 1979

Adon’s history can be traced back to 1979 when the founder started Adon Construction. The Company has been a successful general construction firm which pivoted to solar engineering and procurement in 2007. The company completed many commercial solar facilities in the state of Hawaii. In 2015, Adon focused on direct current (DC) technology development, microgrid development and financing. In its new pursuit, the firm has launched advanced batteries (PowerBox), hybrid solar heat pumps (SunChillers) and bi-directional mobile battery system (evPowerBox).
Making an Impact Across the Globe
Adon designs and integrates commercial and industrial battery storage systems in conjunction with its renewable energy facilities. The team is passionate about protecting the environment and reduce our dependence on fossil fuels. The launch of its high-efficiency SunChillers solar heat pumps aims to greatly reduce energy consumption. The development of PowerBox, a ferrous metal based battery technology, aims to get rid of the cobalt based toxic batteries that are common among the leading brands.

A dedication was held in November 2021 at Kalaeloa for the completion of Kamaʻokū, a village of 37 tiny homes for our koa kahiko (veterans) and homeless individuals on the leeward coast. We are very proud of the Adon team for donating over $100,000 in materials, trenching, electrical / HVAC work and countless hours of engineering for Hawaiʻi first master-planned Kauhale for homelessness. Together, we will rise up to the challenge and build a better community.
