ECA was created to help businesses and homeowners save energy. We conduct energy surveys to find ways to improve energy efficiency. ECA uses energy monitoring, project management, and training to empower the customer to significantly reduce their energy usage.

Our mission is to design and improve energy efficiency, solar hot water and photovoltaic systems in Hawaii and similar climates, and to provide data and information to encourage the use of alternative energy.

Research shows that lowering your energy costs before you install solar-powered energy will save you a bundle!
