Solar panel installation is a fantastic way to harness renewable energy and reduce your energy bills, with a typical payback of less than 10 years! However, to get the most out of your investment, it is vital to consider the best place to install your solar panels, as their position on your property’s roof can significantly affect their performance and efficiency.
In this article, we’ll explain the things you should consider when installing solar panels to ensure they perform at their best.
In the UK, the best position for solar panels is typically facing south because this orientation captures the most sunlight throughout the day. This is particularly beneficial if you reside in the northern parts of the country where sunlight is less intense and, throughout autumn and winter, available for fewer hours a day compared to the south. South-facing panels receive direct sunlight for the longest period as they directly face the path of the sun from east to west, making them the most effective at absorbing and generating electricity.
While south-facing roofs are ideal, east or west-facing installations can also be beneficial and should not be ruled out. Solar panels placed on these orientations will still generate energy, but for fewer hours each day. East-facing panels catch the morning sun, while west-facing panels benefit from the afternoon or, in summer, evening light. This means you can still achieve a good level of energy production, just not as high as with south-facing panels that capture the sun’s rays from dawn until dusk. Solar panels are a wise investment even when south-facing panels are not feasible.
Another factor to consider is the best angle to place solar panels, as this can help to achieve maximum efficiency. The optimal tilt for your panels generally matches your latitude. For instance, if you live at 38° north, tilting your panels at approximately 38° will ensure they capture the most sunlight. This alignment helps to maximise year-round energy production by optimising the angle at which the sunlight is captured.
Generally speaking, solar panels can be installed without planning permission on most properties as they are covered by Permitted Development (PD) rights. However, if your property is a listed building or is located in a conservation area, planning regulations may apply. Therefore, it is essential to consult with your local authority’s (LA) planning department before proceeding with solar panel installation; LA officers will be able to provide guidance on any restrictions or requirements to ensure your installation complies with regulations and what steps you need to take to ensure you comply.
