Indicative UK price ranges for each part of a typical installation. These are guides, not quotes — every property is different.
A solar installation is really a bundle of separate jobs stitched together: panels, inverter, wiring, safety devices, sometimes a battery, sometimes roof or consumer unit work. Below is a rough guide to what each part typically costs.
Supplied and fitted. Panels are usually only around a third of the total installed cost — the rest is inverter, mounting, wiring, labour and scaffolding.
String inverters for smaller systems start around £700–£1,100; hybrid inverters for battery-ready setups typically run £1,500–£2,500. Larger three-phase units can exceed £4,000.
Priced by capacity (kWh). A 5kWh battery starts around £2,500–£4,000; mid-sized 8–10kWh units are £4,000–£6,500; larger 13kWh+ systems from £8,000.
Covers all the cabling, connectors and isolator switches needed between the panels and inverter. Individual isolators are roughly £50–£100 each.
Many older homes need a fuseboard upgrade before a solar or battery system can be safely connected. An SPD adds roughly £80–£150 when fitted as part of the upgrade.
Scaffolding is usually quoted separately. Structural repairs to a single roof section typically cost £250–£500 if needed — most roofs need no extra work.
Covers electrical connection, testing, MCS certification and DNO paperwork. Usually already reflected in the installed prices above.
Because every home is different, total system costs vary a great deal. A modest system with no roof or fuseboard work will land at the lower end of these ranges, while a larger system with a battery, upgraded consumer unit and scaffolding will land considerably higher.
As a very rough steer, small residential systems tend to start in the region of a few thousand pounds, with larger systems including battery storage commonly running into the low-to-mid five figures.
