This solar angle calculator tells you the optimum angle to get the best out of your system.
Optimum solar panel angle adelaide.
Solar panels give the highest energy output when they are directly facing the sun.
It does not describe solar panel tilt and orientation in australia in general as the title might lead one to believe.
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.
Why is a great solar panel angle simply your latitude.
Ideally solar panels would be positioned at an angle of 38 in melbourne equal to the latitude angle of the city 37 81.
So what percentage of solar energy do you lose from not having panels mounted at the optimum angle.
So for my house in adelaide a good solar panel angle is 35 from horizontal.
Well it depends based on the orientation and angle of the panels.
The sun moves across the sky and will be low or high depending on the time of the day and the season.
In 7 of australia s 8 capitals the best angle is at least 3 degrees less than the latitude.
To get the best out of your photovoltaic panels you need to angle them towards the sun.
The solar panel angle of your solar system is different depending on which part of the world you are.
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.
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.
What angle is optimum for solar panels i e.
It s a common belief that panel tilt from horizontal should equal a location s latitude but this is not quite correct.
The key solar system components what angle is optimum for solar panels i e.
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.
Solar output losses when the panel angle is not ideal.
This article is about the best angle to tilt solar panels for the maximum possible energy yield over a year.
Can they be put flat on a roof.
Because your latitude is the same as the angle of the sun in the sky halfway between midwinter and midsummer.
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.
Optimum tilt angle is different for different latitudes.
The sun will be about 15 degrees higher in the sky in summer and 15 degrees lower in the sky in winter.
As australia is in the southern hemisphere the solar panels produce most power when they are pointed directly at the sun i e.
