This is because the sun is always in the southern half of the sky in the northern hemisphere.
Best direction to orient a fixed solar panel.
It is at this location that your panels will receive the maximum sunlight throughout the day.
However there is a difference between magnetic south and true south that must be considered.
If your roof does not face the right direction then surface mounted panels or pole mounted panels may be your best bet.
In the northern hemisphere the general rule for solar panel placement is solar panels should face true south and in the southern true north.
While the angle of your solar panels is important a more important factor in your energy production is going to be the direction your panels face.
Solar panels should face south for any home in america to obtain maximum power generation.
If you re in the u s.
Or elsewhere in the northern hemisphere the best direction for solar panels to face is true south though there is an exception.
Panels mounted on a standard pitch roof facing east or west will produce approximately 15 less output than panels mounted on a south facing roof of a standard pitch.
The more sunlight reaches your solar panels the more electricity you can generate and the more money you ll be able to save on your electric bill.
On the contrary in the countries of the southern hemisphere such as south africa and australia the best orientation is true north.
There is a difference.
What angle for solar panels should be chosen to maximize the production all year long.
However solar panels can be orientated on any roof that faces south of either east or west.
Therefore directions like southwest or southeast are fine.
Orientation of the panels.
The most optimum direction to face your solar panels is somewhere between south and west.
For the best results solar panels should be oriented towards the south.
In this case for the solar panels to get their best performance a steep angle of 60 is best.
In general there s one big rule.
During the spring the best angle is 45 and during the summer when the sun is high in the sky it s best to have a low tilt at 20.
Usually this is the best direction because solar panels will receive direct light throughout the day.
