The correct angle is found by using the homes latitude and correction for true azimuth true north as opposed to magnetic north.
Solar panel angles at polar regions.
A solar panel tilt of 19 degrees will work best in los angeles.
Use one of these formulas to find the best angle from the horizontal at which the panel should be tilted.
Here two simple methods for calculating approximate solar panel angle according to your latitude.
The angle is based on your latitude minus 15 degrees.
True south or the geographic south will yield the best results overall.
This is because the sun is always in the southern half of the sky in the northern hemisphere.
The optimum tilt angle is calculated by adding 15 degrees to your latitude during winter and subtracting 15 degrees from your latitude during summer.
It only takes a few minutes.
What s the best angle for solar panels.
The solar radiation that the panels receive is almost the same.
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.
If your latitude is above 50 see other situationsbelow.
At 90 from true south therefore east and west production can drop to 30.
The answers you end up with are the best angles for each particular season.
Ideally you want your solar system to be on the area of your roof that faces south specifically southwest.
Therefore to get the very best out of your photovoltaic panels you would typically face them due south at the optimum angle so that the panel is receiving as much sunlight as possible at this time.
A fixed tilt panel is angled to receive the maximum benefit from the sunlight year round according to the department of energy.
For the best results solar panels should be oriented towards the south.
One last point to consider is that each person s conditions are different and you may have to make minor adjustments to your setup.
For example with this logic in the bay area near san francisco you would want to tilt solar panels at 22 or 23 degrees.
If your latitude is below 25 use the latitude times 0 87.
However if the panels are turned at an angle greater than 45 compared to true south production begins to decrease significantly.
In the northern hemisphere the sun is due south at solar noon.
As you can see configuring the direction and angle for solar panels is not too complicated.
That s because you ll get way more sunlight hitting the roof thereby converting into way more energy.
