Off-grid solar power systems for homes

Complete solar, battery and generator systems for houses the mains doesn’t reach. Designed from your real loads, installed by us, and monitored by us afterwards.

Systems from £30,000. Most homes land between £30k and £60k for the complete system.

Who this is for

A barn or cottage conversion

The connection quote came back at a number nobody expected. Off-grid stopped being the eccentric option.

A new build with no supply

A plot with no grid nearby. We can size the system from the drawings and, where the array is ground-mounted, have it running before the house is finished.

A house that is already off-grid

Running on an old system, or a generator that never seems to switch off. We replace it with something that just works.

Two of the homes we've powered

Five-bed self-build barn conversion

A family who assumed the grid was close enough, until the quote arrived. Fully off-grid on solar, battery and backup generator.

New-build timber-frame house

Viridian solar roof, BYD battery and Victron inverter. A few metres from a mains supply, and off-grid by choice.

How we design a system

1. Your loads, not your roof

Every appliance, its draw, and when it runs. That sets the inverter size, and the inverter sets the minimum battery.

2. Real yield for your postcode

Array size comes from PVGIS irradiance data for your location, pitch and orientation. December is the month that matters.

3. The generator is backup

On a correctly sized system it should be an unusual sound, not a daily one. We size it, wire it in, and it starts itself.

An option worth knowing: get the power in before the build

Getting your generator and off-grid system in early can save months of generator hire during the build. Where the array is ground-mounted, the system doesn’t need a finished roof — on this site the array, plant room and generator went in first, and the build crew have run off it ever since. If you’re at planning stage, it’s worth a conversation.

What it costs, and why we say so

A complete off-grid system for a house — panels, batteries, inverter, generator, installation and commissioning — typically comes in between £30,000 and £60,000. We put the number here so you can decide before you call.

And a straight answer: if a mains connection is available at modest cost, take it. Off-grid only makes sense when the grid is genuinely out of reach, or you have a reason beyond cost.
