However pitch angles between 30 and 45 degrees will work well in most situations.
Ideal roof angle for solar panels.
Since solar panels are more productive when the sun s rays are perpendicular to their surfaces the certainly best orientation is the one directly true south azimuth angle 180.
Overall the angle of your rooftop has less impact on solar panel performance than the direction your roof faces.
On the contrary in the countries of the southern hemisphere such as south africa and australia the best orientation is true north.
Forbes cited one study that had bloggers questioning whether panels should really face west.
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.
