Solar panel angles by zip code
How does the angle of the sun affect solar panels?
If the sun is low in the sky, the air mass number will be greater than 1 since the angle causes the sun to pass through more atmosphere, resulting in a loss of solar insolation. Finally, the optimal tilt angle (Σ) is the angle at which the solar panel needs to be set to col- lect the most energy from the sun. Figure 5 illustrates these angles.
How do you calculate the tilt of a solar panel?
The tilt should be designed so that the panel points directly at the sun at noon. To calculate, multiply your latitude by 0.9, and add 30 degrees. For example: New York is at 40 degrees. 40 X .9 + 30 = 66 degrees tilt from horizontal. See below for a list of cities and their latitudes.
How does the spreadsheet calculate the sun angles?
The spreadsheet calculates the sun angles at two different times of day. The first is at solar noon, when the sun reaches its maximum altitude in the sky and irradiates the maximum energy for that day. The second is at the given local time.
Which direction should my solar panels face?
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.

the times of day and year when direct solar radiation can strike points within a building through openings in the walls and roof. The key to doing this is the determination of the azimuth (or bearing) and elevation angles of the corners of the shading objects relative to the point of interest.

Each solar cell can be modelled as a basic p-n junction, and hence the classic diode equation can be used in modelling outputs for the solar panel. The diode equation is given by Eqn. 1. where T is the temperature of the solar cell. From this, various models for the electrical energy output of a PV panel have been derived. One such model is ...

These angles are about 10° steeper than what is commonly recommended. The reason is that in the winter, most of the solar energy comes at midday, so the panel should be pointed almost directly at the sun at noon. The third column of the table shows how well this orientation will do compared with the best
