You can also have a good-performing solar panel system if you have an east and west-facing roof, as you will have exposure in both the morning, afternoons and evenings. Your roof may be unsuitable for solar panels if it faces north, as this will have a direct impact on your generation. How can I calculate the orientation of my roof?
This article aims to guide you through these considerations, ensuring that your move towards solar energy is both practical and efficient. A south-facing roof is typically the most optimal choice for solar panel installation due to its prolonged exposure to the sun's rays at their most intense time of day.
As you can see the best roof for solar panels is south facing, with an inclination between 40 to 30 degrees. This type of installation will give your solar panels the most exposure to the sun, over the longest period, resulting in a greater return on your investment.
Glass roofs: As they are too fragile to support the solar panels and fixings. Nevertheless, if your roof isn't suitable for solar panels there are other options too. For example, you may be able to install ground-mounted solar panels to take advantage of any shade-free land you own.
However, this doesn't by any means exclude east and west-facing roofs from being suitable candidates. A south-facing roof is the gold standard and means your house is most suitable for solar panels, but that's not your only option. East-facing roofs capture the morning sun, making them efficient during the first half of the day.
