Sometimes however the homeowner will want to add modules on the north facing roof.
Why should solar panels face north.
Since the sun rises in the east solar panels facing in that direction are more productive in the morning.
Solar panels should face south for any home in america to obtain maximum power generation.
Panels facing west produce around 12 less electricity overall than north facing solar panels.
You should still go solar is what.
There is of course deviance throughout the seasons but ideally solar panels should be facing as close to true north as possible to reduce the impact that the winter seasons have on energy yields.
Because north facing solar panels produce the most electricity overall they will have the greatest environmental benefit.
Installing panels that face north is not recommended since it results in the lowest electricity output.
You might be thinking that the direction your panels should face is obvious and should simply be towards the direction where they will be exposed to sunlight for the most amount of the day but the answer is not that simple.
It s considered common knowledge that you want to point your solar modules south toward the equator assuming you are in the northern hemisphere.
However solar panels can be orientated on any roof that faces south of either east or west.
But in general there s one big rule.
Australia being in the southern hemisphere experiences a sun that is predominantly coming at us from the north.
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 other hand west facing panels are more productive in the afternoon since the sun sets in that direction.
Therefore directions like southwest or southeast are fine.
In fact all southern hemisphere locations should ideally position panels in a northerly direction.
The only roof face you would never install solar panels on is the north face assuming you re living in the northern hemisphere.
In this post we will explore this question further so you can go into your solar project with as much knowledge as possible.
The direction that your solar panels face is fundamental to how much energy they can produce and how much money you can save over time.
For australia solar power yields are higher when panels face north.
The effect of orientation on solar output.
Once again referring to the graph above one can see that even northeasterly and northwesterly facing panels will be largely operating at around the 90 of their rated outputs.
This maximizes the energy production over the course of the year through both summer and winter.
The direction solar panels should ideally face for optimum sun exposure varies depending on location.
A solaray consultant can visit your home and use specially designed software demonstrate the sun and or shade that your particular roof will have in winter summer and at any time during the year.
If you re in australia or elsewhere in the southern hemisphere your solar panels should face north.
While south facing roofs are ideal for maximizing the electricity production for the individual panels it s not the end of the world if your home has and east west orientation.
