Brisbane Solar Panel Angle

This is because it s based on the average position of the sun over your property.

Brisbane solar panel angle. The angle of your solar array is an important factor in maximizing your energy production. In 7 of australia s 8 capitals the best angle is at least 3 degrees less than the latitude. The situation differs again for a city like brisbane where the latitude angle is 27 46. In the above case example of a latitude of 34 the tilt angle will be 34 0 9 29 59 6.

The theoretical optimum configuration is approximately 26 degrees north for tilt angles with pv panels facing true north for orientation. However if the panels are turned at an angle greater than 45 compared to true south production begins to decrease significantly. As shown in the illustration below the sun is lower during the winter months and higher in summer months. We have found brisbane panels should be angled at 26 degrees facing true north says uq global change institute researcher professor tapan kumar saha.

Considering the latitude for brisbane 27 47 deg. In this method the optimum tilt angle for solar panels during winter is calculated by multiplying the latitude by 0 9 and then adding 29. A new university of queensland study has declared the perfect angle and orientation for solar panels in brisbane that will provide optimum power generation. The effect of flat rooftops is less and less of an issue.

To lean toward more production in the winter tilt your panels at your latitude plus 10 15. Most solar arrays are installed at a tilt. To optimize overall production year round tilt your panels at your latitude. The sun is lower in the sky during winter.

In australia common roof pitches are 15 or 22 5 so your modules will most likely be mounted at one of those angles. At 90 from true south therefore east and west production can drop to 30. Energy conservation and management 74 2013 102 108. It s a common belief that panel tilt from horizontal should equal a location s latitude but this is not quite correct.

This result is very close to the rule of thumb a tilt angle approximatley equal to the latitude angle. To lean toward more production in the summer tilt your panels at your latitude minus 10 15. Generally speaking unless your roof is flat the pitch of your home s roof is going to be the angle your solar panels are mounted at. The angle of the sun not only changes based on different latitudes but also with the change of seasons.

In terms of australia the further north you go the lower the latitude angle. This decline is due to the fact that solar panels during most of the day are exposed to weak and not perpendicular sunlight. Solar panel angle by zip code.
