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. Adon has completed many commercial solar facilities in the state of Hawaii.  In 2015, our company began focusing on direct current (DC) technology development, microgrids and renewable energy financing. Our most recent products that were launched are advanced batteries (PowerBox), hybrid solar heat pumps (SunChillers™) and bi-directional mobile battery system (evPowerBox).




Turnkey Solutions and Services

Custom Design:

Our in-house engineering team can customize solutions to meet your specific goals. Adon will work with you to gather and analyze data and help your organization plan for long-term energy decision-making. Adon designs both renewable energy systems, components, and software. We also maintain these complex systems throughout their lifespan. This broad perspective gives our team a unique depth of technical expertise.


Through our general construction experience, Adon has always prioritized safety and quality work. Our team has delivered on new construction as well as coordinated retrofits with existing businesses that minimized impacts to their ongoing operations. Adon is bonded and insured general contractor, and we have been a trusted partner since 1979. We bring those same values to our work in the renewable energy industry.

Energy Management System:

Our PowerBox is equipped with a cloud-based energy management system (AdonEMS) that can control the operation of the battery and provide a monitoring platform of the system operation. The EMS communicates with the battery management system (BMS), power conditioning system (PCS) and DC-DC converter to charge the PowerBox and discharge it efficiently and safely. It provides the necessary data to maintain and troubleshoot the system. 

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.
