Many roofs are going to have slopes between 30 and 40 degrees which means that solar panels can lie flush against the roof and produce enough electricity for attractive returns.
Ideal roof pitch for solar colectots.
One solution is to compensate by increasing the solar collector area either using more panels or larger collectors.
There are several factors in your control when it comes to finding the ideal pitch for your solar panels.
If we are in chicago and we need energy only in the winter season it is good to choose a tilt angle between 53 and 65 example 59 while if we need only in the summer it is good to choose a tilt angle between 19 and 30 example 24 5.
The angle of most rooftops varies depending on the architecture of the house and city in question.
Solar panels facing east or west won t get as much light as those on a southern facing roof.
30 degrees is ideal but as long as it s not too steep to install safely the pitch is relatively unimportant.
You will most likely be installing the solar panels on your roof which is why you have to take into account the roof pitch too.
At this level the solar panel can lie flat on the roof and get enough sunlight to produce enough electricity.
Most roofs have an inclination of 30 to 40 degrees.
For example the latitude of los angeles california is 34 degrees so the tilt of your solar panels would be 34 degrees.
Solar contractors recommend using the latitude of your home s location as the degree of tilt.
Simple the one that meets our energy needs.
Overall the angle of your rooftop has less impact on solar panel performance than the direction your roof faces.
Find the best angle for optimizing solar collection during winter when solar energy is most scarce by multiplying your latitude by 0 89 and then adding 24 degrees.
For instance if your latitude.
Ideally a fixed roof mounted solar energy system should be at an angle that is equal to the latitude of the location where it is installed.
If your roof faces east west rather than north south you have a few options.
If you are trying to install solar panels on a steep roof it may not be possible to place panels at the optimal tilt with traditional racking systems.
