Thinking about switching to solar energy?
That’s a smart move, both for your bills and the planet. But before arranging your solar panel installation in Horley, you must ensure your roof is suitable for it.
Several factors influence the performance of the solar panels installed at any premises. You might not get the expected results if your roof doesn’t meet the mark. Let’s walk through a simple yet thorough checklist to help you decide.
Factors To Consider Before Solar Panel Installation
Knowing the factors that affect the performance of solar panels is not just essential for assessing suitability. It also helps you make the proper modifications, if needed. Knowing the factors enables you to find the ideal installation site and make the most of your investment.
Roof Strength and Structural Integrity
Your roof must handle the solar panels’ added weight and mounting gear. If the structure seems weak, you need to take action before installation. Check for any signs of sagging or internal damage. Concrete and metal roofs usually work the best. Wooden or older tiled roofs may need reinforcement or even complete replacement.
Orientation and Tilt
South-facing roofs work best for solar in the UK. They can soak up the most sunlight throughout the day. A tilt angle between 30° and 40° is usually ideal to ensure the highest efficiency. Even if your roof faces east or west, you can install panels. In that case, the output will be slightly lower.
Shading and Surroundings
Any nearby trees, chimneys, or tall buildings can reduce the solar efficiency of the panels. Even partial shading on a panel can lower the output of the system. You need to assess your roof throughout the day for sunlight exposure before installation.
How Much Space Do You Need?
An average home usually needs 12–16 solar panels. Each panel measures about 1.6m². You’ll need at least 20–25m² of usable roof space. Consult an expert installer to map the panel layout for maximum coverage and minimum clutter.
Your roof plays a significant role in the success of your solar energy journey. Strength, sunlight, and space, all of these factors work together to ensure efficiency and safety.
