The angle of your solar panels matters because more power is made when sunlight hits the panels at a right angle. However the sun is high in the sky in summer and low in the sky in winter… so the question becomes how do you optimise them for winter or summer?
There is plenty of sunlight in summer. The longest day of the year in Melbourne is almost 15 hours. By contrast in winter there is only about 9.5 hours of sunlight on the shortest day of the year. When you are living off the grid you want to set the optimal tilt for winter to get as much sun on the panels when you need it the most.
Going Off Grid Technicians will line your solar panels up where they should be using specialist equipment and years of experience.
