Therefore directions like southwest or southeast are fine.
Ideal orientation for fixed solar panels.
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.
As a general rule of thumb keep in mind that the panels need to be more vertical during winter to face the lower sun directly and more tilted towards the ground during summer to face the higher sun.
Since solar panels are more productive when the sun s rays are perpendicular to their surfaces the certainly best orientation is the one directly true south azimuth angle 180.
After finding the best place to install your solar panels your installer will select the ideal tilt.
The angle is calculated based on your latitude.
A simple rule to follow in the united states is to multiply your latitude by 0 76 then add 3 1 degrees.
The orientation of the panels is important to capture a maximum of sunlight and therefore produce a maximum of energy.
On a fixed installation what direction is best to have the best production.
Solar panels should always face true south in the northern hemisphere north in the southern hemisphere tilted from the hoizontal at a degree equal to your latitude plus 15 degrees in winter or minus 15 degrees in summer.
Usually this is the best direction because solar panels will receive direct light throughout the day.
Solar panels should face south for any home in america to obtain maximum power generation.
South facing roofs receive the most sunlight and therefore the most solar energy during the day.
Orientation of the panels.
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.
In the northern hemisphere the general rule for solar panel placement is solar panels should face true south and in the southern true north.
For example with this logic in the bay area near san francisco you would want to tilt solar panels at 22 or 23 degrees.
The angle is based on your latitude minus 15 degrees.
This is because the sun is always in the southern half of the sky in the northern hemisphere.
A solar panel tilt of 19 degrees will work best in los angeles.
It just depends on where you live.
For the best results solar panels should be oriented towards the south.
Calculating the ideal angle for your solar panels is not that difficult.
