MCS-certified 3kW solar panel system 3kW 8 panels for a 2 to 3 bed home, generating 2,550 to 2,850 kWh a year.

For most 2 to 3 bed homes using 2,500 to 3,500 kWh a year, a 3kW system covers a meaningful share of annual electricity. With a 5 kWh battery, self-consumption typically reaches 70 to 90%, meaning most of what the system produces is used in the home rather than exported.

8 panels using modern high-efficiency modules, sized to deliver 3 kW DC nameplate output. On most terraced and semi-detached homes they fit on a single roof slope.

18 to 24 square metres of unshaded roof. South, south-east and south-west aspects perform best in UK conditions, and a single slope is usually enough.

A 5 kWh battery is the most common pairing and the smallest size where the maths works for most households. The inverter is hybrid-ready as standard, so you can add storage later without rewiring.

A 3kW system contributes during daylight but is not usually sized to run an EV or heat pump on its own. If either is on your list, a 5kW or 6kW system is usually a better starting point.

Most installations are carried out under our own MCS registration. Further afield we use installers working under our MCS registration, and the certificate and workmanship warranty remain ours. We handle all paperwork, grid approvals, MCS certification and SEG export-tariff setup on your behalf.
