What angle and orientation are best for solar panels in australia.
Best direction for solar panels melbourne.
So to help people decide what is the best direction to face their panels for all the australian capitals i ll describe.
Although melbourne is a bit further south than brisbane or sydney there s still enough sunshine to make panels a worthwhile investment.
The effect of orientation on solar output.
Due north is the best direction for panels to be facing in the.
The direction in which panels will generate over 99 9 of maximum possible output.
Ground mounted solar panels can even be placed on trackers which adjust the position of the panels throughout the year in order to maximize the amount of sunlight reaching them.
The most optimum direction to face your solar panels is somewhere between south and west.
The direction solar panels should ideally face for optimum sun exposure varies depending on location.
Taking into account efficiency losses because no solar pv system will be able to use 100 of the solar energy it captures the daily energy output of different solar pv system sizes installed on a north facing roof in melbourne with 85 efficiency should be as follows.
It s determined by the shape of their roof.
This table shows you how much energy you can expect to get from almost any combination of solar panel direction and angle in the capital cities compared to the optimum orientation.
If your roof does not face the right direction then surface mounted panels or pole mounted panels may be.
Solar panels to suit a very hot climate some panels have better temperature tolerance than others look for a lower temperature coefficient and are therefore a better choice in hot climates.
According to pvwatts a typical melbourne home s roof receives about 4 8 kilowatt hours kwh of raw sunshine per square meter per day while the bom gov au website averages work.
What you re compromising on is not just the time of an installation team it s also the quality of the mounting kit running high voltage cables safely using good quality isolators the main fire risk doing a clean job and providing support for you after the installation is done.
Hi i live in seymour victoria north of melbourne and i am considering installing 4 4 5kw solar system.
Solar panels are installed differently based on their geographic locations throughout the world.
Up to 5 4kwh for a 1 5kw system.
For australia solar power yields are higher when panels face north in fact all southern hemisphere locations should ideally position panels in a northerly direction.
Australia is home to some of the best solar energy resources in the world.
Up to 7 2kwh for a 2kw system.
For example in brisbane if your panels are facing west 270 and are angled 20 from horizontal you will get 89 of the energy compared to the optimum orentation of north and 30.
Best direction for my panels.
Of course most people don t get to decide which direction they face their solar panels.
It is at this location that your panels will receive the maximum sunlight throughout the day.
