Optimal Solar Panel Angle Uk

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.

Optimal solar panel angle uk. As we re in the northern hemisphere the best solar panel orientation is obviously south but. Therefore in london which has a latitude of around 51 degrees solar panels should ideally be mounted at an angle of approximately 65 degrees. For the far south of england the optimal roof angle would be closer to 30 degrees. We ll also explain how the best solar panel angle is based on different factors.

Orientation of the panels. In the far north of scotland your panels would perform better if your roof angle was 40 degrees. This solar angle calculator tells you the optimum angle to get the best out of your system. For a latitude between 25 to 50 take your latitude multiply by 0 87 after that you will add 3 1 degrees.

If your latitude is between 25 and 50 then the best tilt angle for summer is the latitude times 0 93 minus 21 degrees. The summer optimum tilt angle on the other hand will be 34 15 19. The optimum tilt angle is calculated by adding 15 degrees to your latitude during winter and subtracting 15 degrees from your latitude during summer. The best tilt angle for winter is the latitude times 0 875 plus 19 2 degrees.

For a latitude up to 25 take your latitude and multiply it by 0 87. Mounting angle for solar panels in general photovoltaic solar panels should be mounted at an angle of 10 to 15 degrees plus the site s latitude. For the best results solar panels should be oriented towards the south. For a latitude over 50 the most ideal angle will end up being approximately 45 degrees.

This is because the sun is always in the southern half of the sky in the northern hemisphere. If your latitude is outside this range see other situations below. Finally we examine how important it actually is to achieve the optimal angle. The effect of shading on solar panels shading is a big problem for solar photovoltaic panels.

On the other hand if we have a greater need during the summer season it is good to have a tilt angle between 19 and 42 for example 30. While the angle of your solar panels is important a more important factor in your energy production is going to be the direction your panels face. This table gives some examples. For instance if your latitude is 34 the optimum tilt angle for your solar panels during winter will be 34 15 49.

If instead we have a greater need during the winter season it is good to have a tilt angle between 42 and 65 for example 53. You ll see the terms used interchangeably both in this article and across the internet. Solar panel angle is also known as solar panel tilt.
