Energy Alternatives has been designing and delivering solar and battery systems since 2006, with more than two decades of hands-on experience in renewable energy across New Zealand and, for the past decade, a dedicated focus on Waiheke Island.

We specialise in practical, technically sound systems that suit island conditions — systems that work reliably, are easy to maintain, and deliver strong long-term value. Our work is grounded in experience, local knowledge, and clear communication with every customer.

Energy Alternatives is an accredited SEANZ practitioner, ensuring all system designs and installations align with recognised national standards for safety, performance, and long-term durability.

For installation and specialist work, we collaborate with trusted SEANZ-accredited electricians, qualified contractors familiar with island requirements, and national product partners who provide engineering support and long-term warranty coverage. This keeps systems compliant, serviceable, and fully supported throughout their life.

Our commitment is simple: to provide clear, reliable advice, design systems that fit real needs, and ensure long-term reliability through sound design, quality components, and trusted installation partners.

Energy Alternatives continues to support homes, businesses, and community facilities across Waiheke with practical, trustworthy renewable-energy solutions. The approach is steady, technically grounded, and built on long-term relationships — not on high-volume sales. Customers work directly with an experienced practitioner from start to finish, supported by specialists chosen for their skill, integrity, and fit with the job.

Whether it’s a home, business, or community facility, we remain focused on delivering solar and battery systems that perform well, fit local conditions, and stand the test of time.
