It turns out that you can do better than this about 4 better.
Solar panel angle to sun.
Cosine of solar zenith angle.
Az el both report dark after astronomical twilight.
Azimuth angle is their horizontal facing in relation to the equator.
The optimum angle varies throughout the year depending on the seasons and your location and this calculator shows the difference in sun height on a month by month basis.
Solar panels give the highest energy output when they are directly facing the sun.
These angles will give you the best overall output over the course of the year if you re going for a fixed installation.
Similarly you can calculate the angle for winter by adding 15.
Azimuth is measured in degrees clockwise from north.
If you do plan to optimize solar collection in every season use the following calculations.
The tilt angle or elevation angle describes the vertical angle of your solar panels.
There are two methods for calculating the tilt angle for solar panels.
For instance in the san francisco bay area the best solar panel tilt angle is between 22 23 degrees.
Both of these angles require latitude degrees.
Photovoltaics produce power when the angle at which the sun s rays hit the panel surface the angle of incidence is small or when light strikes the panel as close to perpendicular as possible.
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.
For that reason the ideal angle is never fixed.
For los angeles a solar panel tilt of 19 degrees works the best.
The sun moves across the sky and will be low or high depending on the time of the day and the season.
Solar panels should face directly into the sun to optimize their output.
The solar panel angle of your solar system is different depending on which part of the world you are.
Elevation is measured in degrees up from the horizon.
On the contrary in the countries of the southern hemisphere such as south africa and australia the best orientation is true north.
For spring and fall multiply your latitude by 0 98 and subtract 2 3 degrees.
