The Solar Panel Angle

However it s fair to say that the general overview range that s good enough in most places in the country is between 25 and 35 degrees.

The solar panel angle.

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. Similarly you can calculate the angle for winter by adding 15. If it s standing upright perpendicular to the ground it is at a 90 angle. As we ve mentioned there is no one best angle for all regions in the usa.

The tilt angle or elevation angle describes the vertical angle of your solar panels. Solar panel angle is another way of describing the vertical tilt of your pv system. Books and articles on solar energy often give the advice that the tilt should be equal to your latitude plus 15 degrees in winter or minus 15 degrees in summer. Both of these angles require latitude degrees.

It turns out that you can do better than this about 4 better. Azimuth angle is their horizontal facing in relation to the equator. For instance if your latitude is 34 the optimum tilt angle for your solar panels during winter will be 34 15 49. When a solar system is level with the ground it has no tilt.

The summer optimum tilt angle on the other hand will be 34 15 19. Whatever your latitude is you can subtract 15 from it to calculate the angle for summer. There are two methods for calculating the tilt angle for solar panels. Therefore the best angle for your solar panels is the one that allows the panels to get the most direct perpendicular light.

The next question is at what angle from horizontal should the panels be tilted. On the contrary in the countries of the southern hemisphere such as south africa and australia the best orientation is true north. Solar panels produce electricity when sunlight hits their surface and they produce the most energy when that sunlight is exactly perpendicular to the panel face. Solar panels should face directly into the sun to optimize their output.

Ultimately what s the best angle for solar panels in the usa. To get the best out of your photovoltaic panels you need to angle them towards the sun.
