We started with flat panels and increased the angle of tilt to the south to see how much extra energy is gained through the year. A rule of thumb that seems to have spread around is that the optimal tilt angle is about equal to the degree of latitude of the location. Therefore we include a result at a tilt of 33.4 degrees, the latitude of Phoenix.
Therefore, the ideal solar panel angle for your array would be about 34 degrees. However, if you lived in New York City, NY, where your latitude averages about 40.7 degrees N, you might set your tilt angle at 41 degrees. Remember, you can expect the tilt angles to vary by about 15 degrees as the sun's location fluctuates with the seasons 5.
Results are shown in the graph below. Tilting the panels significantly increases energy output (read our article to find out solar panels power generation rate). The maximum output, at 30 degrees tilt, is 14% higher than the energy output of flat panels. Over the 25 year life of the panels, that's a lot of energy.
The solar panel angle is calculated in relation to the ground or the horizontal plane of the equator in technical terms. Solar panels must be installed perpendicular to the sun to generate maximum energy output. The angle of your solar panels perpendicular to the sun changes depending on the latitude of your residenc e.
The performance of solar panels varies depending on several factors, one of which is the tilt angle of the solar array. What is a tilt angle? It refers to the number of degrees your array is tilted
