Ideal Roof Pitch For Solar Colectots

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. 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. Solar panels facing east or west won t get as much light as those on a southern facing roof. Most roofs have an inclination of 30 to 40 degrees.

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. Overall the angle of your rooftop has less impact on solar panel performance than the direction your roof faces. For instance if your latitude. At this level the solar panel can lie flat on the roof and get enough sunlight to produce enough electricity.

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. 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. However pitch angles between 30 and 45 degrees will work well in most situations. Ideally solar panels would be positioned at an angle of 38 in melbourne equal to the latitude angle of the city 37 81.

Solar contractors recommend using the latitude of your home s location as the degree of tilt. There are several factors in your control when it comes to finding the ideal pitch for your solar panels. If your roof faces east west rather than north south you have a few options. 30 degrees is ideal but as long as it s not too steep to install safely the pitch is relatively unimportant.

For example the latitude of los angeles california is 34 degrees so the tilt of your solar panels would be 34 degrees. The angle of most rooftops varies depending on the architecture of the house and city in question.
