A 6.6 kW solar system in Auckland (4.2 peak sun hours) with 80% system efficiency generates approximately 6.6 × 4.2 × 365 × 0.80 ≈ 8,100 kWh per year. Christchurch gets slightly more sun, so expect around 8,700 kWh/year in a similar system there.
Solar payback periods in NZ typically range from 7–12 years depending on system cost, electricity rates, and self-consumption. With an average import rate of $0.32/kWh and moderate self-consumption, a $12,000 system often pays back in around 8–10 years.
