Solar panels in Wellington
A 6.6kW home solar system in Wellington typically costs $14,000 to $15,000 installed (Solar Scout, 2026) and generates about 8,250 to 9,250 kWh a year, based on 1,250 to 1,400 kWh per kW. Wind matters here: the roof-mounted consent exemption only applies without an engineer's design in wind zones up to High.

Common questions in Wellington
Consent rules are national: since 23 October 2025, most roof arrays under 40 m² need no building consent. See the consent guide.
Is solar worth it in Wellington?
It can be. Output is lower than Auckland (1,250 to 1,400 kWh per kW a year versus 1,350 to 1,450) but the price you avoid is the same. The deciding factors are how much you use in daylight and your roof. Try the calculator.
Do I need a building consent for solar in Wellington?
Not for a roof array under 40 m² in a wind zone no higher than High. Above that, the exemption needs a design carried out or reviewed by a Chartered Professional Engineer (EWRB).
