The solar calculator incorporates solar data sourced from the National Institute of Water and Atmospheric Research (NIWA) through its SolarView service.
The solar calculator is designed to assess the value of a solar electricity system for your household. You will be asked to provide details about your house, your energy usage, and how you intend to pay for a solar electricity system. The tool will then estimate the value of installing a solar electricity system at your house, including your estimated total earnings (if any) over the course of 25 years, and the estimated number of years that it would take for you to earn back your initial investment.
