The summer optimum tilt angle on the other hand will be 34 15 19.
Best angle for solar panels in winter.
For instance if your latitude is 34 the optimum tilt angle for your solar panels during winter will be 34 15 49.
Subtract 15 degrees from the latitude at your location during summer and add 15 degrees to your latitude during winter.
In general a steeper slope is preferable during the summer as the sun will be higher in the sky.
For a precise method use the second formula on this page to calculate tilt angle.
The optimum tilt angle is calculated by adding 15 degrees to your latitude during winter and subtracting 15 degrees from your latitude during summer.
This is about 10 more or less from the readings obtained using the first method.
So you would actually make an adjustment 11 to the west to find the ideal azimuth.
The same latitude of 35 would have a tilt angle of 59 6 for winter and 7 1 for summer.
I live in buffalo new york.
However installing panels at angles of around 15 degrees or less can backfire as snow won t easily fall off of your array.
There s a simple rule of thumb for calculating the best tilt angle for fixed mount solar panels.
At some places as much as a vertical tilt of the panels is needed to get the maximum output during wintertime.
It snows a lot.
In this way at noon the panels will be perfectly perpendicular to the sun s rays.
Some years it seems like winter lasts for nine months.
And yet i have a solar panel system that still provides some electricity in the dark winter months.
The result for chicago is 90 42 23 25.
During winter the sun is lower and to catch more of its light the best solar panel angle would be more tilted.
To get maximum energy efficiency during the winter solstice the solar panels in chicago must face south and be tilted 65 90 25.
