How many panels should you install?

We often get asked how many panels can be installed on a residence and there are no set rules regarding this, but there are a few things to consider...


In the UK, there are no specific limits on the number of solar panels that you can install on your home. However, there are a number of factors that may impact the number of solar panels you can install and the overall size of your solar array, including:

  1. Available roof space: The amount of available roof space will dictate how many solar panels you can physically fit on your roof. The orientation and angle of your roof will also impact the performance of your solar panels, as they need to be positioned to receive maximum sunlight.

  2. Planning restrictions: If your home is in a conservation area or is a listed building, you may need to obtain planning permission before installing solar panels. Some local authorities may also have restrictions on the size or appearance of solar panels, so it's important to check local planning regulations before installing solar panels.

  3. Electrical capacity: Your home's electrical capacity may also limit the number of solar panels you can install. You may need to upgrade your electrical system to accommodate a larger solar array.

  4. Budget: Finally, the cost of installing solar panels may be a limiting factor for some homeowners. The cost of a solar panel system will depend on the size of the system, the quality of the panels, and the complexity of the installation.

Overall, while there are no specific limits on the number of solar panels you can install on your home in the UK, there are a number of practical and regulatory factors that may impact the size and performance of your solar array.
