Solar panels are a popular choice for those looking to generate their own electricity and reduce their carbon footprint. However, one important consideration when installing solar panels is which direction they should face. In the United Kingdom, this can have a significant impact on the amount of energy generated.
The direction that solar panels face is important because it affects the amount of sunlight that they receive throughout the day. In general, solar panels in the UK should face south in order to receive the maximum amount of sunlight. This is because the sun is at its highest point in the sky around noon, and is therefore in the southern part of the sky during the day.
However, not all properties have a south-facing roof that is suitable for installing solar panels. In these cases, it may be necessary to install solar panels on a roof that faces east or west. While this will result in lower energy generation than a south-facing roof, it can still be a viable option.
If you are considering installing solar panels on a roof that faces east or west, it is important to take into account the orientation of your property. For example, if your property is located in the northern hemisphere, a roof that faces east will receive more sunlight in the morning, while a roof that faces west will receive more sunlight in the afternoon. This is because the sun rises in the east and sets in the west.
Another factor to consider is the angle of the roof. Solar panels are most effective when they are installed at an angle that is optimised for the latitude of the location. In the UK, this is typically around 30 degrees. If your roof is not at this angle, it may be necessary to install brackets or supports to adjust the angle of the panels.
It is also important to consider any shading that may affect the performance of your solar panels. Shading can be caused by trees, neighbouring buildings, or other obstructions that block the sunlight. Even a small amount of shading can significantly reduce the energy generation of your solar panels, so it is important to choose a location that is free from shading.
In addition to the direction that solar panels face, it is also important to consider the size and number of panels that you will need. The size of your solar panel system will depend on your energy needs, as well as the amount of sunlight that your location receives. In general, a typical home in the UK will require a solar panel system that is between 3 and 4 kW in size.
Overall, the direction that solar panels face is an important consideration when installing a solar panel system in the UK. While south-facing roofs are ideal, it is still possible to generate electricity from solar panels on east or west-facing roofs. By taking into account the orientation of your property, the angle of your roof, and any shading that may affect your solar panels, you can ensure that your solar panel system is optimised for maximum energy generation.
