Pv Panels Roof Pitch

Pitch and solar pv as well as the orientation the angle at which the panels are pitched is important.

Pv panels roof pitch. This means that for best results the roof pitch of your property should ideally be equal to the latitude angle with the panels mounted at the same angle as the roof. 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. These flat roofs are also commonly known as. Trackers are structures which hold the solar panels in order to move and or tilt them according to the position of the sun.

Where panels cover more than 33 of the roof a 36 in wide path is required on both sides of the ridge. However pitch angles between 30 and 45 degrees will work well in most situations. Overall the angle of your rooftop has less impact on solar panel performance than the direction your roof faces. 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.

For example if you reside in sydney a roof pitch of 34 would be considered ideal as this is equal to the latitude angle 33 86 of the nsw capital. For example a 7 12 roof pitch means that for ever 12 of horizontal distance the roof will increase in height by 7. Flat roofs have a minimal slope allowance that will accommodate solar pv panel systems. For example the latitude of los angeles california is 34 degrees so the tilt of your solar panels would be 34 degrees.

Solar roof is comparable in price to a typical roof with solar panels. If you are looking at a roof plan for your home or business very rarely will it list the roof pitch in degrees instead it lists the rise and the run of the roof. Solar contractors recommend using the latitude of your home s location as the degree of tilt. The ideal angle is about 30 degrees off the horizontal simply because this allows the panels to extract more from the sun in the morning and the evening whilst still making the most of the mid day sun.

For roofs where pv panels cover up to 33 of the total area in plan view essentially as seen from above the panels must be at least 18 in. The following diagram will let you easily convert roof pitch. 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. Away from a horizontal ridge on both sides to create the 36 in wide path.

This is a good option if the house roof cannot support the panels or there is a building with a better roof angle for maximum sun exposure. There are several factors in your control when it comes to finding the ideal pitch for your solar panels.
