Solar power myths busted
People always ask "what happens when it's not sunny?" and "will my solar power still work in winter?" The answer is yes to both.
Solar power is not reliant on heat, only sunlight and UV rays. Solar panels will even work in fog and on cloudy days - perfect for the Dunedin climate!
The amount of power generated will depend on the thickness of the fog or cloud but at its worst, your panels might produce only 5-10% of the energy they normally do. Even if you live in an area with lots of foggy days, what really matters is how much sunshine your roof receives over the course of a whole year, not on a given day.
