Best Angle For Solar Panels In Winter

By doing this you are setting up your panels to perform more efficiently in the winter because they will more directly face the sun as it shines from a lower point in the sky.

Best angle for solar panels in winter.

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 snows a lot. During winter the sun is lower and to catch more of its light the best solar panel angle would be more tilted. Some years it seems like winter lasts for nine months.

In this way at noon the panels will be perfectly perpendicular to the sun s rays. The result for chicago is 90 42 23 25. For a precise method use the second formula on this page to calculate tilt angle.

This is about 10 more or less from the readings obtained using the first method. I live in buffalo new york. The same latitude of 35 would have a tilt angle of 59 6 for winter and 7 1 for summer. Subtract 15 degrees from the latitude at your location during summer and add 15 degrees to your latitude during winter.

There s a simple rule of thumb for calculating the best tilt angle for fixed mount solar panels. And yet i have a solar panel system that still provides some electricity in the dark winter months. However installing panels at angles of around 15 degrees or less can backfire as snow won t easily fall off of your array.

The summer optimum tilt angle on the other hand will be 34 15 19. For instance if your latitude is 34 the optimum tilt angle for your solar panels during winter will be 34 15 49. Solar panel lifespan guide are solar trackers helpful.
