With energy prices continuing to rise and modern solar systems becoming more affordable, the business case for commercial solar has never been stronger. Across New Zealand, the commercial solar boom is well underway.
Many businesses with high daytime energy use can now fund solar installations with monthly finance costs that are equal to — or sometimes less than — their current electricity bills.
At Energy Alternatives, our goal is to help your business become as energy-efficient as possible before recommending the most suitable solar solution. Whether you’re a small business, large commercial site, or industrial operation, there is almost always an opportunity to reduce operating costs and improve resilience through solar.
We assess your energy profile, goals, and site conditions to design a system that delivers strong performance and measurable financial benefits — improving operational stability and supporting a more sustainable future.

We also work with you to identify complementary energy efficiency improvements such as:
Whatever your energy profile, our team will help you find the most cost-effective solution that fits your operational needs and budget.



Energy Alternatives was selected as the preferred installer for Waiheke High School’s 2023 solar project.
The system includes 200 × 375W solar panels, delivering 75kWp of capacity to a 100kW inverter in a grid-tied configuration.
To future-proof the installation, we sponsored an upgrade from the originally proposed 68kWp (with two smaller inverters) to a single 100kW Huawei inverter.
This provides more efficient performance now and allows room for future expansion.
Our design team also analysed the school’s energy usage patterns and strategically placed 60 panels on an east-facing roof to support high morning electricity demand — a modification that has proven highly effective via system monitoring data.
Waiheke High School engaged Energy Alternatives for a large solar installation after a competitive evaluation process. EA recommended a Solar Study, which helped us make an informed decision as all tenderers worked from the same system metrics. The Board approved the project due to the strong financial and environmental benefits, and the learning opportunities for students.
The 75kWp system installed includes 200 solar panels and has performed reliably since commissioning. As a local Waiheke supplier, EA made installation straightforward and provides ongoing support. Their contract pricing was honoured, and their responsiveness has been excellent. We are happy to recommend Dana and the Energy Alternatives team for their professionalism and commitment.
