Look for installers who are SEANZ-accredited and who fit panels and inverters from established brands, such as Fronius or SolarEdge, backed by a proper manufacturer warranty - this matters more for long-term reliability than chasing the lowest quote.
From September 2026, electricians carrying out grid-tied solar work need the Electrical Workers Registration Board's Endorsed Mains Parallel Generation Systems registration when their licence comes up for renewal, so it's reasonable to ask your installer about this. Since October 2025, most residential rooftop solar installs under 40m² per roof are exempt from needing a building consent, though a good installer will still handle the network connection paperwork and, from July 2026, help you understand the time-of-use export rebates major electricity retailers are now required to offer.
Cost depends on system size, roof type and the panel/inverter brand you choose. Get a fixed, itemised quote from at least two of the installers above so you're comparing like for like before deciding.
Since October 2025, most residential rooftop solar installations under 40m² per roof no longer need a building consent under an MBIE exemption. Your installer should confirm your project qualifies and still handle any required electrical compliance paperwork.
Unused power is exported back to the grid. From July 2026, major electricity retailers are required to offer time-of-use pricing and pay rebates for solar exported during peak times, so it's worth checking with your retailer about the best export deal for your system.
Yes. NIWA climate data for the Manawatu-Whanganui region shows around 2,000 sunshine hours a year, which makes solar a genuinely worthwhile investment for homes in and around Whanganui.
A battery isn't essential but lets you store daytime solar generation for evening use, reducing how much power you draw from the grid. Ask your installer for a cost comparison with and without a battery based on your household's actual usage pattern.
