The following is a guest post by dr.
Which direction should solar panels face in south africa.
Generally it s common knowledge in the solar industry that these south facing panels should be tilted between a 30 and 40 degree angle.
Find out in about 60 seconds.
So what direction should solar panels face.
Solar south or geographic south.
To make the most of the sun in south africa it is best to install on roofs that face north.
However the electricity system is not as simple as it sometimes seems and the best direction to face solar panels may actually be west.
The climate and geographic area also affect the working ability of solar panels.
For the best results solar panels should be oriented towards the south.
The conventional wisdom in the northern hemisphere is that the best direction to face solar panels is south since that is generally where they d receive the most sunlight.
In darwin south facing panels only produce about 15 less electricity overall than north facing panels but as the northern territory still has a high feed in tariff the most cost effective direction to face solar modules is north.

If your roof does not face the right direction then surface mounted panels or pole mounted panels may be your best bet.
To correct the compass reading your solar installer will calculate the magnetic declination of your site.

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.
This is measured on a case by case basis depending on the location.
It is at this location that your panels will receive the maximum sunlight throughout the day.
The pull or magnetic declination will vary in direction and strength depending on your location.
The direction solar panels should face is true south a k a.
Panels can be placed in multiple directions other than just an east west split.
In the northern hemisphere the sun crosses the sky a little to the south which means putting solar panels on a south facing roof is the best way for homeowners to capture the most solar energy.
This angle varies and is just about equal to the latitude of your home how far north you are in relation to the equator.
This is because the sun is always in the southern half of the sky in the northern hemisphere.
The most optimum direction to face your solar panels is somewhere between south and west.

True south can also be calculated at noon when shadows from vertical objects run north south.
