During winter, the Southern Hemisphere of the Earth is tilted away from the sun, receiving less direct sunlight compared to summer. This results in lower solar panel efficiency and shorter daylight hours. Although South Africa gets copious amounts of sunshine for much of the year, it is not immune to the impact of winter on solar power. . South African winters are often crisp, clear, and full of sunlight, which are ideal conditions for solar panels – or so it seems. But as many solar users are discovering, blue skies don't always guarantee peak performance. It's important that we, as consumers, also understand how our energy needs and behaviours shift through the different seasons so that we can implement practical steps to. . “The change in weather, specifically the length of day in winter versus summer, has a direct impact on your solar performance,” says Ross Mains-Sheard, Co-Founder and CEO of Versofy SOLAR.
