For the best results solar panels should be oriented towards the south.
Optimal solar panel angle uk.
The optimum tilt angle is calculated by adding 15 degrees to your latitude during winter and subtracting 15 degrees from your latitude during summer.
If your latitude is between 25 and 50 then the best tilt angle for summer is the latitude times 0 93 minus 21 degrees.
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.
Solar panel angle is also known as solar panel tilt.
But before we begin a quick note.
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 far south of england the optimal roof angle would be closer to 30 degrees.
You ll see the terms used interchangeably both in this article and across the internet.
Orientation of the panels.
We ll also explain how the best solar panel angle is based on different factors.
Finally we examine how important it actually is to achieve the optimal angle.
The summer optimum tilt angle on the other hand will be 34 15 19.
In the far north of scotland your panels would perform better if your roof angle was 40 degrees.
Solar panel orientation in the uk your solar panel orientation is very important when it comes to maximising the amount of electricity that your solar panels will produce.
If your latitude is outside this range see other situations below.
For instance if your latitude is 34 the optimum tilt angle for your solar panels during winter will be 34 15 49.
For a latitude between 25 to 50 take your latitude multiply by 0 87 after that you will add 3 1 degrees.
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.
The best tilt angle for winter is the latitude times 0 875 plus 19 2 degrees.
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.
This table gives some examples.
Therefore in london which has a latitude of around 51 degrees solar panels should ideally be mounted at an angle of approximately 65 degrees.
As we re in the northern hemisphere the best solar panel orientation is obviously south but.
This is because the sun is always in the southern half of the sky in the northern hemisphere.
The effect of shading on solar panels shading is a big problem for solar photovoltaic panels.
For a latitude over 50 the most ideal angle will end up being approximately 45 degrees.
To get the best out of your photovoltaic panels you need to angle them towards the sun.
