You’ll get:
Panel BearingNorthNorth EastNorth WestEastWest
The direction your panels will face (from Due North). This is usually the direction your roof faces.
Panel Angle10°20°30°40°
Angle your panels are installed at. Usually this matches the pitch of your roof but panels could be mounted on tilt frames for flatter roofs.
Number of Panels
Estimate how many panels you can fit (panels are approximately 1.8m tall x 1.15m wide).
Your Annual Usage (kWh)
What is your yearly energy consumption, you can usually get an idea from your power bill.
Amount of Solar Output You’ll Use (%)
This depends on how much power you use when the solar is working. For typical households this is 25-50% – don’t worry, you will export the rest for a credit on your power bill.
Import Rate ($)

Daily Fixed Rate ($)
Your daily fixed charge on your power bill.

Using your own solar power gives the biggest return. Export rates are lower than what you pay to import power.
More panels generate more energy, but the right size depends on your usage profile.
Rising electricity costs increase the value of solar over time.
North-facing panels at optimal tilt produce the most energy in NZ conditions.
Why solar is a smart investment
For commercial sites, solar also helps stabilise operating costs and future-proof infrastructure.
