Our Customer
Altherm Joinery West Auckland is a window manufacturing facility based in West Auckland, New Zealand. It specialises in manufacturing thermally efficient windows and doors for the commercial and residential sectors.

As a manufacturer, the business relies heavily on the power grid, leading to high energy expenditure. Moreover, Altherm was keen on boosting its sustainability profile, adopting a greener operational model and as a result, differentiate itself from its competitors.

How we helped

After Choice Energy undertook a solar feasibility assessment, it was recommended a 20kW commercial solar system would help to combat the business’ rising operational costs with projected savings of up to $6,000 per year.

As part of Choice Energy’s commercial solar solution, the business receives a performance guarantee and ongoing system monitoring.
