Best Angle To Install Solar Panels

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.

Best angle to install solar panels.

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. These angles will give you the best overall output over the course of the year if you re going for a fixed installation. On the contrary in the countries of the southern hemisphere such as south africa and australia the best orientation is true north. The optimum angle varies throughout the year depending on the seasons and your location and this calculator shows the difference in sun height on a month by month basis.

But to do this many factors come into play the best tilt angle for solar panels direction of the sun location of the panels climate latitude the season and more. In order to collect energy more efficiently solar panels should be angled to face as close to the sun as possible. At some places as much as a vertical tilt of the panels is needed to get the maximum output during wintertime. Once you have figured this out you can use one of the formulas below to calculate the best angle for your solar panels for each season.

Latitude x 0 9 23 5 degrees. Overall the angle of your rooftop has less impact on solar panel performance than the direction your roof faces. In general a steeper slope is preferable during the summer as the sun will be higher in the sky. Photovoltaics produce power when the angle at which the sun s rays hit the panel surface the angle of incidence is small or when light strikes the panel as close to perpendicular as possible.

The answers you end up with are the best angles for each particular season. Latitude 2 5 degrees. During winter the sun is lower and to catch more of its light the best solar panel angle would be more tilted. Most roofs have an inclination of 30 to 40 degrees.

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. At this level the solar panel can lie flat on the roof and get enough sunlight to produce enough electricity. Specifically the tilt of the panels has an effect on the efficiency of the energy production of energy panels so it s important to understand what angle is best for your. However pitch angles between 30 and 45 degrees will work well in most situations.

To get the best out of your photovoltaic panels you need to angle them towards the sun.
