Which Roof Azimuth Is Ideal For A Solar Installation

If the array is installed on the north facing roof the annual energy production would be reduced up to 35.

Which roof azimuth is ideal for a solar installation.

As solar power is a cleaning energy its application is fast increasing spread the world. Optimal electricity production occurs when solar panels face south at a tilt equal to 30. The vertical tilt of your panels. However even if you lower the tilt of your roof all the way down to 5 production only decreases by about 10 percent.

Welcome to another entry in our ongoing solar 101 series. I n planning the design of a diy home solar project panel placement is particularly important knowing the direction your rooftop faces known as the roof s azimuth is key to determining the optimal tilt and orientation of your photovoltaic array. Elevation angle and azimuth angle commonly shortened to angle and azimuth for brevity. Today we re going to explain how to mount your solar panels to get the most energy from them.

The angle of your roof actually has less impact on solar panel performance than the direction your solar energy system faces. On the contrary in the countries of the southern hemisphere such as south africa and australia the best orientation is true north. In general the more directly your rooftop faces south the higher annual energy production you can expect from your diy solar power system. One solution to overcome the azimuth angle effect would be to install a solar pv system on a single axis solar tracker.

The array on the east roof would generate slightly more energy than the one on the west roof.
