For the best results solar panels should be oriented towards the south.
Does it matter which way you orient solar panels.
Solar panel angle is another way of describing the vertical tilt of your pv system.
On the other hand if you live in the southern hemisphere you can use this same technique.
The size of solar panels makes them well suited to be installed vertically on most roofs.
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.
It is easier to have a continuous row of solar panels if they are installed vertically.
Like monocrystalline polycrystalline boasts a long lifespan and usually comes bundled with a 25 year warranty.
Or elsewhere in the northern hemisphere the best direction for solar panels to face is true south though there is an exception.
That is the rule of thumb for the northern hemisphere.
This helps determine the best positioning for solar panels.
This is a simple tried and true way to find the perfect direction and like i said you can do it with no tools.
If you re in the u s.
Polycrystalline solar panels pros.
This is because the sun is always in the southern half of the sky in the northern hemisphere.
If it s standing upright perpendicular to the ground it is at a 90 angle.
However in some cases it may be better to install them horizontally or at some other angle for other considerations.
Recently the new york times and popular science even purported that solar panels should face west rather than south to avoid unintended consequences.
However each of the above only considers.
The other important factor is angle.
In general there s one big rule.
Fewer rails are required to mount a solar panel vertically instead of horizontally.
There are a few reasons why most solar panels are installed vertically.
As you may have read elsewhere solar panels should face true south.
For the southern hemisphere solar panels should face true north.
However you would want to face your solar panels in the opposite direction of where your shadows face.
When a solar system is level with the ground it has no tilt.
Polycrystalline panels are somewhat less efficient than monocrystalline panels think 13 16 efficiency rather than 15 20 but not by much and for the slight decrease in efficiency you can save a considerable amount of money.
It does so by spinning counterclockwise along its axes.
This will help optimize energy output.
This table shows you how much energy you can expect to get from almost any combination of solar panel direction and angle in the capital cities compared to the optimum orientation.
