How Much Would 12 Solar Panels Cost?

If there is enough suitable roof space, adding more panels could increase annual generation. But installing as many panels as possible is not automatically the right approach.

The extra panels cost money, and their value depends on how much electricity your household can use or export.

Grid capacity can also influence the final design. Roof shape, shading and local grid conditions can all affect the size of a suitable system.

A good design therefore starts with your electricity needs and the property, then works out how much solar capacity makes sense.

Does A Battery Change The Price?

Yes, and it can change how you use the electricity your panels produce.

Solar generation usually rises during daylight hours. Your household may not use all of that electricity at the same time. A battery can store some of the surplus and make it available later.

For example, you might generate more electricity around lunchtime while nobody is using much power. In the evening, when lights, cooking and other appliances are being used, the battery can provide some stored electricity.

A battery adds to the initial cost, so do not assume it is automatically the right choice. Ask for two figures from the installer: the price for the solar system on its own and the additional cost of adding storage.

That makes the difference much easier to judge.

What Could Add To The Installation Cost?

A basic quote may not tell the whole story until the property has been assessed.
