This is because for those of us living in the northern hemisphere the sun is always along the southern part of the sky as we complete our yearly orbit around it.
Is my house south facing for solar panels.
Solar pv panels are most effective on a broad south facing roof at least in the northern hemisphere.
Ideally they should face true south which is a slightly different direction from the magnetic south you would find with a compass.
Go west young one.
Well when it comes to solar panels west is second best.
An easy way to find out if your roof and thus your property is good for solar is to look it up on google maps.
In order to collect energy more efficiently solar panels should be angled to face as close to the sun as possible.
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.
And when it comes to orienting solar panels most people will simply choose the south which the compass points to.
Most solar arrays are installed at a tilt.
The traditional advice is to position solar panels to be south facing.
However the economics of installing solar panels on a roof that does not face the south still usually stack up for the homeowner.
