When considering the installation of solar panels, one of the most common questions that arises is ‘do I need a south-facing roof for solar panels?’. While a south-facing orientation is indeed ideal for capturing the maximum amount of sunlight throughout the day, it’s not the only factor to consider when determining the suitability of your roof for solar panels. In this blog post, we’ll explore the importance of roof orientation, as well as other factors that can influence the effectiveness of solar panel installation, to help you make an informed decision.
Roof Orientation
A south-facing roof orientation is typically recommended for solar panel installation in the northern hemisphere, as it receives the most sunlight over the course of a day. This orientation allows solar panels to capture sunlight from sunrise to sunset, maximising energy generation potential. However, this doesn’t mean that solar panels won’t work on roofs facing other directions. East-facing and west-facing roofs can still generate significant amounts of solar energy, so you have nothing to worry about there.
Considerations for East or West-Facing Roofs
If your roof faces east or west rather than south, solar panels can still be a viable option. East-facing roofs receive sunlight in the morning, which can be advantageous for homes with high energy consumption during the morning hours. Similarly, west-facing roofs receive sunlight in the afternoon and evening, making them suitable for homes with greater energy needs later in the day. It can also be an idea to place panels on both sides of the roof, whenever possible, to maximise the energy generated from your solar system.
It is important to also consider the fact that while sunlight is beneficial to generating energy through solar panels, it is not the be-all and end-all. Our specialist solar systems can generate energy through daylight, and they do not need to be in the sun constantly to do this.
Roof Pitch and Shading
In addition to orientation, the pitch of your roof and potential shading from nearby trees or buildings can also impact the performance of solar panels. A roof with a steep pitch may be less suitable for solar panel installation, as it can reduce the efficiency of the panels and make maintenance more challenging. Similarly, shading from trees or neighbouring structures can cast shadows on solar panels, decreasing their output. Before installing solar panels, it’s important to assess your roof’s pitch and any potential shading issues to ensure optimal performance. Our team can advise on this at your survey and will never sell you a system that, in the long-term, is not suitable for your home.
Consultation with Solar Professionals
