Correct Positioning of your Solar Panels System in Canberra A.C.T.
We examine here some of the most important factors relevant to solar power installation in Canberra and around the A.C.T.
The positioning of you solar panels requires an understanding of a several factors. However, most of what you need to know does not require extensive education or skill. An understanding of the effects of shade, wind, temperature, and solar mount type allows anyone to identify the best place to mount their solar panels system in the best spot to maximize its solar energy production.
Solar panels work best when exposed to the maximum amount of sun possible. Shaded areas will reduce the output of even the best solar arrays. If you cannot find – or make – a large treeless area, at least try to find an area that is not shaded during peak hours. For most homes in Canberra, peak hours will be from 7 a.m. to 5 p.m.
Creating an area with adequate sunlight does not require large amounts of time or energy. Trimming trees back will often replace the need to completely remove them. If you are debating whether to remove a tree, be sure and think about wind loads.
The A.C.T. can experience times of very strong winds. Determine wind conditions in the area before positioning your solar array. Spacing the panels at least a few inches apart will reduce the wind load considerably. The trees that might block some sun from reaching your arrays might make up for the lower efficiency by acting as a wind break during stormy weather.
Keep in mind that solar panels work by using the light from the sun and not the heat generated by the sun. Heat decreases the efficiency of a solar panel. A cold sunny day is preferable to a hot sunny day.
One way to keep the solar panels cool even on warm days is to space the panels apart. This spacing enables air circulation which then cools the panels.
Type of Solar Array
The type of solar array that you purchase is a factor that determines positioning. There are three basic types of solar arrays: fixed mount, adjustable mount, and tracking mounts.
Fixed mounts should be pointed towards the equator. Use an angle of inclination that matches your home’s latitude. A slightly higher inclination will favor winter sunlight and the opposite will favor summer lighting. Fixed mounts are your cheapest option but might lack enough flexibility for your location.
Adjustable mounts can be changed for seasonal variations. An angle of inclination of 20 degrees to 40 degrees in the winter and – in the summer should be about right for much of the A.CT. and region. Adjustable mounts increase efficiency over fixed mounts by about 25%. They are usually a great compromise between fixed mounts and more expensive tracking mounts.
Tracking mounts allow the user to follow the sun on a single or double axis. Single axis mounts travel east to west. Double axis mounts include east to west and seasonal inclination tracking options. Tracking mounts increase efficiency up to 30% over fixed mounts and increase your options for positioning.
Positioning your solar panel array does not have to be complicated. Just remember to check for areas with ample sun exposure and protection from the wind. Then, position the arrays far enough apart to reduce heat buildup. Be sure and buy the solar array mount that gives the best options for your property.
Most of the properties in Canberra have an acceptable roof pitch angle and special mounting is not required.
