In the United Kingdom, rooftop solar has become increasingly popular in recent years. This renewable energy source allows homeowners to generate their own electricity and reduce their reliance on the national grid. However, one of the challenges of installing rooftop solar is the presence of power lines. In this article, we will explore which power lines rooftop solar can be installed under in the UK.
Firstly, it is important to understand the different types of power lines in the UK. The National Grid is responsible for the high voltage transmission network, which carries electricity from power stations to local substations. These power lines are typically located on large pylons and can be up to 400kV. Distribution network operators (DNOs) are responsible for the lower voltage distribution network, which carries electricity from substations to homes and businesses. These power lines are typically located on wooden poles and can be up to 33kV.
When it comes to installing rooftop solar, the type of power line that is present will determine whether it is possible to install solar panels. If the power line is a high voltage transmission line, it is unlikely that rooftop solar will be permitted. This is because the safety regulations around high voltage lines are very strict, and it is not safe for people to be working in close proximity to them. Additionally, the National Grid has a policy of not allowing any structures to be built within the safety zone around their power lines. This safety zone is typically 50m either side of the power line.
If the power line is a distribution line, it may be possible to install rooftop solar. However, there are still some restrictions to be aware of. DNOs have their own safety regulations which must be followed, and they will need to approve any solar installation that is located near their power lines. The exact distance required between the solar panels and the power lines will vary depending on the voltage of the line, but as a general rule, solar panels should not be located within 3m of a 11kV distribution line, and 6m of a 33kV distribution line.
Another factor to consider when installing rooftop solar near power lines is shading. If the solar panels are shaded by the power lines or any nearby trees, their efficiency will be reduced. This is because solar panels work best when they are exposed to direct sunlight. It is therefore important to ensure that the solar panels are located in a position where they will receive maximum sunlight throughout the day.
In conclusion, rooftop solar can be installed under certain types of power lines in the UK. If the power line is a high voltage transmission line, it is unlikely that solar panels will be permitted due to safety regulations. If the power line is a distribution line, it may be possible to install solar panels, but DNOs will need to approve the installation and there will be restrictions on the distance between the solar panels and the power lines. It is also important to consider shading when installing rooftop solar near power lines. By following these regulations and guidelines, homeowners can safely install rooftop solar and generate their own renewable energy.
