Solar panels are an excellent way to generate renewable energy, and they have been increasingly popular in the UK over the past few years. However, one question that often arises is “what angle should solar panels be placed at?” In this article, we will explore the different factors that influence the angle of solar panels and the optimal angle for solar panels in the UK.
Factors that influence the angle of solar panels
1. Latitude
The angle of solar panels is largely influenced by the latitude of the location where they are installed. This is because the angle of the sun changes with latitude. In the UK, the latitude ranges from 50°N to 59°N, which means that the optimal angle for solar panels will be different from other parts of the world.
2. Time of year
Another factor that influences the angle of solar panels is the time of year. In the summer, the sun is higher in the sky, and in the winter, it is lower. This means that the optimal angle for solar panels will be different depending on the season.
3. Roof orientation
The orientation of the roof also plays a role in determining the angle of solar panels. In the UK, south-facing roofs receive the most sunlight, followed by east-facing and west-facing roofs. North-facing roofs receive the least amount of sunlight.
4. Shading
Shading is another factor that can influence the angle of solar panels. If there are trees or buildings that cast shadows on the solar panels, they will not receive as much sunlight, and the angle of the panels may need to be adjusted accordingly.
Optimal angle for solar panels in the UK
In the UK, the optimal angle for solar panels is between 30° and 40°. This angle allows the panels to capture the most amount of sunlight throughout the year. However, if the roof is not south-facing, the angle may need to be adjusted to ensure that the panels are facing the sun.
If the roof is east-facing or west-facing, the optimal angle for solar panels is between 20° and 30°. This angle allows the panels to capture the most amount of sunlight in the morning and evening when the sun is lower in the sky.
If the roof is north-facing, solar panels may not be the best option as they will not receive enough sunlight to generate sufficient energy. In this case, alternative renewable energy sources may need to be considered.
Conclusion
In conclusion, the optimal angle for solar panels in the UK is between 30° and 40°, but this can vary depending on the latitude, time of year, roof orientation, and shading. It is important to work with a qualified solar panel installer who can assess your roof and determine the best angle for your solar panels to ensure that you are generating the most amount of energy possible. With the right angle and installation, solar panels can be an excellent way to generate renewable energy and reduce your carbon footprint.
