The residential 6.6kW solar system is the go-to solution for New Zealand family homes — the most-installed solar system size in the country for good reason.
Is 6.6kW Right for Your Home?
A 6.6kW system is typically ideal for households with 2–5 people, daily electricity use of 15–30 kWh, a quarterly electricity bill of $350–$700+, and at least 30–40m² of suitable roof space.
How Much Can You Save?
Net electricity bill reduction of $150–$250+ per month is common — approximately $1,800–$3,000 per year. Over a 25-year system life, this represents extraordinary cumulative savings.
Increase Your Property Value
New Zealand property research shows solar panels consistently add value to residential properties, often exceeding the net system cost after rebates.
