Brisbane solar panel angle.

This decline is due to the fact that solar panels during most of the day are exposed to weak and not perpendicular sunlight. The sun is lower in the sky during winter. Considering the latitude for brisbane 27 47 deg. To optimize overall production year round tilt your panels at your latitude.

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

This article is about the best angle to tilt solar panels for the maximum possible energy yield over a year. A flat roof in brisbane will operate at 90 of its optimum capacity for the location. A new university of queensland study has declared the perfect angle and orientation for solar panels in brisbane that will provide optimum power generation. It s a common belief that panel tilt from horizontal should equal a location s latitude but this is not quite correct.

In australia common roof pitches are 15 or 22 5 so your modules will most likely be mounted at one of those angles. However if the panels are turned at an angle greater than 45 compared to true south production begins to decrease significantly. 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 your solar array is an important factor in maximizing your energy production.

Most solar arrays are installed at a tilt. The angle of the sun not only changes based on different latitudes but also with the change of seasons. To lean toward more production in the summer tilt your panels at your latitude minus 10 15. The effect of flat rooftops is less and less of an issue.

In 7 of australia s 8 capitals the best angle is at least 3 degrees less than the latitude. Solar panel angle by zip code. 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. In terms of australia the further north you go the lower the latitude angle.

We have found brisbane panels should be angled at 26 degrees facing true north says uq global change institute researcher professor tapan kumar saha. As shown in the illustration below the sun is lower during the winter months and higher in summer months. At 90 from true south therefore east and west production can drop to 30.
