Guide to Positioning Solar Panels on the Roof in the UK

Installing solar panels on your roof is an excellent way to generate renewable energy and reduce your carbon footprint. Properly positioning solar panels maximizes their efficiency and energy production. Here is a step-by-step guide on how to position solar panels on the roof in the UK.

1. Assess Roof Suitability:

  • Check if your roof is suitable for solar panel installation. It should ideally be south-facing or have a south-west or south-east orientation to receive maximum sunlight.
  • Evaluate the roof's condition to ensure it can support the weight of the solar panels. If needed, consult a professional for a structural assessment.

2. Calculate Solar Panel Capacity:

  • Determine your energy needs and calculate the required solar panel capacity. Consider your average energy consumption, available roof space, and budget.
  • Assess the orientation and pitch of your roof, as these factors affect the panels' energy production. A roof angle between 30 and 45 degrees is generally optimal.

3. Shade Analysis:

  • Identify any potential sources of shading that could affect solar panel performance. Nearby trees, chimneys, or neighbouring buildings may cast shadows.
  • Use shading analysis tools or consult with a solar panel installer to evaluate the shading impact and find the optimal positioning for maximum sunlight exposure.

4. Roof Layout Considerations:

  • Determine the number of solar panels you can accommodate on your roof. Consider the available roof space, desired panel size, and local regulations regarding setbacks, spacing, and overhang.
  • Take into account obstructions such as vents, skylights, or dormers that may limit the available roof area for solar panels.

5. Mounting Options:

  • Roof-integrated: Panels are flush with the roof surface, providing an aesthetically pleasing appearance.
  • Roof-mounted: Panels are mounted on top of the roof, allowing for easy installation and maintenance.

6. Obtain Necessary Permissions:

  • Check with your local authorities and building regulations to determine if any permits or permissions are required for solar panel installation.
  • Some areas may have specific rules regarding the position and appearance of solar panels, so it's crucial to comply with the local regulations.


Remember, solar panel installation can be complex, so it's advisable to consult with a professional to ensure optimal positioning and efficient energy generation. By carefully planning and positioning your solar panels, you can make the most of the available sunlight and maximize your clean energy production in the UK.
