Optimum Solar Panel Angle Adelaide

Solar output losses when the panel angle is not ideal.

Optimum solar panel angle adelaide.

It does not describe solar panel tilt and orientation in australia in general as the title might lead one to believe. In the spring summer and autumn the efficiency is lower 74 75 in spring autumn and 68 74 in summer because in these seasons the sun travels a larger area of the sky and a fixed panel can t. Ideally solar panels would be positioned at an angle of 38 in melbourne equal to the latitude angle of the city 37 81. The sun moves across the sky and will be low or high depending on the time of the day and the season.

Well it depends based on the orientation and angle of the panels. First of all in the choice of the tilt angle for solar panels on a house roof we are bound to satisfy two basic needs. What angle is optimum for solar panels i e. Solar panels give the highest energy output when they are directly facing the sun.

The sun will be about 15 degrees higher in the sky in summer and 15 degrees lower in the sky in winter. The solar panel angle of your solar system is different depending on which part of the world you are. So for my house in adelaide a good solar panel angle is 35 from horizontal. As australia is in the southern hemisphere the solar panels produce most power when they are pointed directly at the sun i e.

Optimum tilt angle is different for different latitudes. So what percentage of solar energy do you lose from not having panels mounted at the optimum angle. Can they be put flat on a roof. This solar angle calculator tells you the optimum angle to get the best out of your system.

It s a common belief that panel tilt from horizontal should equal a location s latitude but this is not quite correct. The optimum angle varies throughout the year depending on the seasons and your location and this calculator shows the difference in sun. In winter a panel fixed at the winter angle will be relatively efficient capturing 81 to 88 percent of the energy compared to optimum tracking. In 7 of australia s 8 capitals the best angle is at least 3 degrees less than the latitude.

The need for energy production and the need for an aesthetically pleasing and long lasting final result the roof of a house already has its own inclination and slope so a. Why is a great solar panel angle simply your latitude. The key solar system components what angle is optimum for solar panels i e. Can they be put flat on a roof.

Sunlight is more powerful when it is directly overhead and hitting the earth surface or a solar panel at an angle of 90 such as at midday in summer so keeping the sunlight striking the surface of the solar panel close to 90 is desirable for maximum efficiency. I believe jarrah harburn has taken that graph unreferenced from your home technical manual for latitude 35 s. The paragraph above on tilting seems plain wrong. Well now that we know that the optimal direction is south we need to find the optimal tilt angle.
