Solar hot water in New Zealand

Solar hot water in New Zealand

Solar hot water in New Zealand is increasingly used on both new and existing buildings.

Solar thermal technologies had a sizable initial uptake in the pioneering days of the 1970s. By 2001 more that 40GW/hr was produced from solar hot water technologies, equating to 0.1% of the total electricity consumption in New Zealand.cite web|url=http://www.eeca.govt.nz/eeca-library/renewable-energy/solar/report/solar-energy-use-and-potential-in-nz-01.pdf|title=Solar energy use and potential in New Zealand|last=Energy Efficiency and Conservation Authority|date=May 2001|publisher=Energy Efficiency and Conservation Authority|accessdate=2008-10-01] In 2006 the government announced an investment of $15.5 million over the first three and a half years of a five year Solar Water Heating programme to increase the number of solar hot water heating installations. As of 2006 there were about 35,000 solar hot water installations on domestic and commercial buildings.

There are now eleven manufacturers and importers in the industry with most of the collector system being locally made.

Barriers to adoption

The main barrier for the installation of solar hot water systems is the initial capital investment. Other barriers are the conservatism of the building industry, lack of influence on increasing the sale price of houses, conflicting interest between housing investors and homeowners, and a lack of adequate information about solar hot water heating.
