Case Study
Family of four in three bedroom house in Nelson:
– Total system cost = $5200 (incl GST) includes building consents and installation
– Marginal cost = $3300 (hot water cylinder = $1900)
– Save 3000kWh/year electricity– Save $360/year (marginal cost of
electricity = 12 c/kWh)– Simple payback = 9.2 years
