As the world moves towards renewable energy sources, solar panels have become increasingly popular. They utilise the sun’s rays to generate electricity, which can be used to power homes, businesses, and even vehicles. However, the efficiency of solar panels is dependent on the angle and orientation at which they are installed. This article will explore the best angle and orientation for solar panels and why it matters.
The best angle for solar panels is directly related to the latitude of the installation site. If the solar panels are installed at the same angle as the site’s latitude, they will receive the most sunlight over a year.
For instance, if the installation site is at a latitude of 50 degrees, the optimal angle for the solar panels would be 50 degrees. However, this angle is not always possible due to various factors such as building structures, trees or other obstructions. In such cases, the angle should be adjusted to the nearest available angle.
Bear in mind that the solar panel’s angle changes depending on the time of year. During the summer, the sun is higher in the sky, so that the optimal angle would be lower. Conversely, during the winter, the sun is lower in the sky so that the optimal angle would be higher.
The orientation of solar panels is important for maximum efficiency. In the United Kingdom, solar panels should face south to capture the most sunlight. This is because the sun is in the southern part of the sky for the majority of the day. East and west-facing panels can still generate electricity, but not as efficiently as south-facing panels.
It is worth noting that shading can significantly reduce the efficiency of solar panels. Even partial shading may cause a noticeable decrease in electricity generation. Therefore, it is important to consider any potential shading when installing solar panels. This can include but is not limited to trees, buildings, and other obstructions.
In some cases, it may be necessary to install solar panels on a roof that is not facing south. It is still possible to achieve good efficiency by adjusting the angle of the panels. For example, if the roof faces east, the panels can be angled to face slightly to the southeast. Similarly, the panels can be angled to face slightly to the southwest if the roof faces west.
A Few More Energy-Saving Tips to Consider
- Keep the Panels Clean: Dirt, debris, and other obstructions on the surface of solar panels can reduce their efficiency. Regular cleaning can help maintain their performance.
- Monitor the Performance: Keep track of the amount of electricity your solar panels generate. Doing so will help you identify any issues or changes in performance.
- Invest in High-Quality Panels: High-quality solar panels may cost more upfront but offer better efficiency and longer lifespan, making them a good long-term investment.
- Consider a Battery Storage System: A battery storage system can store excess electricity generated by solar panels during the day for use during peak demand or when the sun is not shining.
The efficiency of solar panels is affected by various factors such as location, orientation, and shading. To maximise electricity generation, install solar panels in an area with high sunlight exposure facing south. Additionally, any potential shading should be considered during installation, and the angle of the panels can be adjusted to compensate for non-optimal orientation. With the proper installation, solar panels can provide a significant renewable energy source for many years.
