We are combining information from MBIE and NIWA to use a custom sunshine profile, electcricity cost and usage data to calculate savings homeowners can make.
By using actual data, we eliminate a lot of the guesswork that current calculators are making - existing products in New Zealand use user-entered constants for values like how much of the electricity they will have to sell back to the grid, whereas we can compare the sunshine profile across different months of the year for a given address with trend data for household electricity usage by month.
Our proof of concept site shows a single grid-connected system, but we are keen to see this project expanded to include residential battery packs when they become viable, and commercially-scaled systems. There is also scope to customise power usage based on users power bills.
With this we believe we can encourage the use of renewable energy and the shift towards smarter cities and communities.
