What moves the price
- System size — more panels or tubes cover a bigger roof area and need more pipework and fixing time.
- Roof height and access — solar panels on a steep or high roof need scaffolding or extra safety equipment, which adds to the cost.
- Installation complexity — swapping the hot water cylinder for one with a solar coil adds plumbing work and parts.
- Materials used — the type of solar panels and hot water tank chosen changes the price of the system.
- Condition of your existing plumbing — older pipework to the hot water tank may need replacing to handle the heat from solar panels.

- Sizing the solar thermal system to your household's hot water use, rather than filling the whole roof, keeps panel costs down.
