This map is designed to help anyone from homeowners, to farmers, to businesses, get a simple understanding of how much solar energy any given location in Southland can receive. If you’re exploring the potential for solar panels or interested in the sunlight of a given area. This map provides you with:
Electricity Grid
1. Solar Radiation (GTI)
Standing for Global Tilted Irradiation, this shows how much sunlight hits a solar panel when it’s positioned at the best angle. It gives you a good sense of how ideal a location is for solar throughout the year.
More GTI = more potential electricity from your solar panels.
As a rough guide:
2. Panel Tilt Angle
This tells you the angle a solar panel should tilt to catch as much sunlight as possible. Southland’s latitude and seasons affect this angle, so it’s different from place to place.
3. Panel Orientation
Orientation means which way your solar panels should face for the best performance, in Southland it is usually somewhere towards true North.
4. Electricity grid.
You can also turn on power network layers to see how close you are to existing electrical infrastructure, which can be useful if you’re thinking about connecting a larger solar system, such as at a solar farm scale (above 300 kilowatts).
This map is part of the Energy in the Landscape programme led by Great South, and the solar data is sourced from the Global Solar Atlas.
