1. Initial Cost

The cost of your solar panel installation will primarily depend on the size (number of panels) of your system, and any additional extras such as battery storage you may wish to have. The size of the solar panel system you need depends on several factors, including energy consumption, roof orientation, and shading. See if solar panels are right for you.


2. Ongoing Costs (Maintenance and Durability)

Solar panels require very little maintenance. We recommend an annual service to remove dust, debris and bird droppings (often a window cleaner will be able to provide this service). While the panels themselves often last for 25 years or more, the inverter may require replacement during this period, costing around £750.


3. Annual Returns

One of the primary advantages of solar panels lies in their ability to substantially reduce electricity costs. This is done by reducing the amount of electricity you have to buy from the grid, and by generating an income in the form of Smart Export Guarantee (SEG) payments.

We have more information about the Smart Export Guarantee below.
