In November 2025, the New Zealand Energy Efficiency and Energy Conservation Agency (EECA) released a significant draft public specification (SNZPAS6014) for residential solar photovoltaic and battery storage systems, open for public comment from that date until October 9, 2025. This is New Zealand's first comprehensive technical guidance document for solar products, marking a new stage in the standardization of the country's clean energy market.

The draft specification covers core equipment such as solar panels, inverters, and battery storage systems, aiming to provide consumers with scientific and independent professional advice to help households choose suitable solar systems based on their needs. The specification also details regulatory requirements for grid connection of solar systems and key information such as how to sell excess electricity back to the grid. EECA plans to use this document for compliance guidance in the solar equipment industry, with the technical specification section (Appendix B) listing acceptable standards and related solutions for various systems.
