Welcome to the New Zealand Solar Industry Association Website.

The Solar Industries Association (SIA) represents the collective interests of manufacturers, importers and installers of solar water heating systems, and provides a single point of contact to the industry.

This website provides information on New Zealand suppliers and installers of solar water heating systems. It lists:

Solar water heating systems are a smart investment and can be installed in new buildings, in your current building with connection to your existing hot water heating system, or with a complete replacement high efficiency hot water cylinder.

Solar systems are inexpensive to install, provide free energy once installed, and reduce overall water heating costs

The key to a successfully operating solar water heating system is the quality of the design of the system as a whole (collector, tank, pumps and controller) and the experience of the installer. The Association sets standards for its members and assists them to meet these requirements. It recognises this through accrediting appropriate supplies for installation.

To ensure you are purchasing a quality system you should choose a product from an accredited solar water heating supplier/or their approved installer.
