The Best Direction for Solar Panels: Optimising Your Solar Energy System

When installing solar panels, one of the most crucial considerations is the direction they should face. Proper orientation can significantly enhance the efficiency and energy output of your solar energy system, ensuring you get the most from your investment. This blog will explore the best direction for solar panels, explain why it matters, and provide tips for optimal installation.

Why Direction Matters

Solar panels work by converting sunlight into electricity. The more sunlight they receive, the more electricity they generate. Therefore, the direction in which your solar panels are installed plays a pivotal role in maximising their exposure to sunlight. Ideally, you want your solar panels to receive the most sunlight throughout the day.

The Optimal Direction in the UK

In the UK, the optimal direction for solar panels is south-facing. This orientation ensures that your panels receive direct sunlight for the longest period during the day, especially during peak sunlight hours. South-facing panels can capture sunlight from sunrise to sunset, maximising energy production.

What If South-Facing Isn’t an Option?

Not all properties have a south-facing roof. If your roof faces east or west, you can still achieve good results, though the efficiency might be slightly lower compared to a south-facing installation. East-facing panels will capture more sunlight in the morning, while west-facing panels will do better in the afternoon. North-facing installations are generally not recommended in the UK, as they receive the least amount of direct sunlight.

Considering Roof Angle

The angle of your roof also affects the efficiency of your solar panels. In the UK, an angle between 30 to 40 degrees is typically ideal. This range allows the panels to capture the maximum amount of sunlight throughout the year. If your roof’s angle is not within this range, mounting systems can be used to adjust the panels to the optimal angle.

Shading and Obstructions

To ensure maximum efficiency, it’s important to consider any potential shading from nearby trees, buildings, or other obstructions. Even partial shading can significantly reduce the energy output of your solar panels. When planning your solar power installation, ensure that your panels will have a clear path to sunlight throughout the day and year.

The Role of Technology

Advancements in solar technology, such as microinverters and power optimisers, can help mitigate some of the issues related to suboptimal panel orientation and shading. These devices optimise the energy production of each panel individually, ensuring better overall system performance.

Working with Professionals

Choosing a professional solar energy company like Britek Solar ensures that your system is designed and installed for optimal performance. Experienced installers can assess your property and recommend the best setup for your specific situation, considering all factors such as orientation, roof angle, and shading.

The Importance of Maintenance

Regular maintenance is essential to keep your solar panels functioning efficiently. Cleaning the panels to remove dirt and debris and ensuring that there are no new obstructions that could cause shading are simple yet effective ways to maintain high energy output. Britek Solar offers comprehensive maintenance services to help you keep your system in top condition.

Considering Energy Storage

For many homeowners and businesses, pairing solar panels with an energy storage system can further enhance the benefits of solar power. Energy storage for solar panels allows you to store excess energy generated during the day for use during the night or on cloudy days, providing greater energy independence and reducing reliance on the grid.

Solar Panels for Businesses

If you run a business, installing solar panels can significantly reduce your energy costs and contribute to your sustainability goals. Many solar panel installation companies offer tailored solutions for businesses, helping them to maximise their energy savings and environmental impact.


The direction your solar panels face is a critical factor in maximising the efficiency and output of your solar energy system. In the UK, south-facing installations are ideal, but east and west orientations can also be effective. Working with a professional installer like Britek Solar ensures that your system is optimised for the best performance. Regular maintenance and considering additional technologies like energy storage can further enhance the benefits of your solar investment.
