Solar Panel Output: Solar panels in New Zealand typically have a capacity ranging from 300W to 400W, with output measured in watts. To determine the number of panels required, divide your daily energy consumption by the average daily solar irradiance and the output of a single panel. . The average New Zealand home uses between 7,000 and 9,000 kWh per year, which translates to about 19 to 25 kWh per day. However, homes with high electricity demand due to appliances like heat pumps, electric water heating, or electric vehicles will require more energy. But that number differs widely based on your situation. The specific appliances you own and how often you use them also play a major role. e 1 kilowatt (kW) = 1000 Watts.
