Solarcity NZ Ltd / Solarzero

solarZero is the nation’s leading solar energy services company and a proud member of SEANZ. Over the past 35+ years it has put more solar systems on Kiwi homes and businesses than any other company. It was the first solar company in the world to achieve Toitū carbonzero certification and is still the only solar energy services business in NZ with that green credential. solarZero is one of the fastest-growing green companies in New Zealand and is one of the Government’s Focus 500 companies that are targeted to contribute significant benefits to the New Zealand economy.

solarZero's rich history as pioneers of innovation in solar energy development began in Christchurch in the 1970s, with the company’s early beginnings as Thermocell, a solar water heating company that was started by Professor Arthur Williamson and his colleagues from the University of Canterbury.
Under the guidance of founder Andy Booth, the company evolved to become New Zealand’s leading solar energy business with offices in Christchurch, Nelson and Auckland. Over the past 35+ years it has put more solar systems on Kiwi homes and businesses than any other company.

Driven by strong values and a mission to help Kiwis access smarter, cleaner energy, the company continues to innovate and deliver on the shared value of Kaitiakitanga - the Maori principle of guardianship. It’s a constant reminder we have a duty of care to look after our place, our people and the generations to follow.
