We Care Group — four care homes, one rollout

A repeat client across the North West. Four residential care sites surveyed, designed and installed in sequence, each sized to its own roof and load profile — with residents in place throughout.

The programme at a glance

Care homes run around the clock, so daytime generation displaces expensive grid units almost hour for hour. Across the four sites the combined array now covers a substantial share of daytime demand.

“I never got to mention the great job you've done. A few of the homes went out of their way to mention the guys on site were nice, friendly and helpful — for a care homes manager to say that is very high praise! From my perspective, you've been easy to work with and come up with practical solutions to problems; so grateful to all of you.” — Robert Feeley, We Care Group

Manchester · We Care Group

The largest of the four sites. A sprawling single-storey footprint gave plenty of well-oriented roof, spread across multiple pitches and wings.

A terraced-block site needing full scaffold access, phased so residents and staff were never without a safe route in and out.

Large roofs, large returns

Where consumption is high and daytime-heavy, the numbers get dramatic — and payback periods get short.

Blum

Milton Keynes

The largest array on this page. A vast flat distribution roof turned into a 397.8 kWp generating asset — now supplying over a third of a gigawatt-hour a year, and paying for itself in two and a half.

“We recently had the pleasure of working with River Energy, and we couldn't be happier with the results! From start to finish, their team exhibited professionalism, expertise, and a genuine commitment to excellence… In summary, River Energy exceeded our expectations and are highly recommended by Blum.” — Raj Tanna, Blum

Food production runs hard through daylight hours, and cold storage never stops. Both roof pitches were filled — and the system has out-performed its own forecast.

“River Energy made the whole process easy for us from start to finish. Nothing was too much trouble and a special mention must go to the installers who were very polite and made sure our work processes were not slowed down during installation. The solar system has been very impressive and is producing 30% more electric generation than was estimated.” — Andrew Barkworth, Managing Director, Sunshine Saltfish
What these projects share

Every one started the same way

A free survey

Roof condition, orientation, shading and half-hourly consumption — before a single figure was promised.

A modelled payback

Yield and savings projected up front, so the business case was signed off on numbers, not optimism.

Delivery around the client

Care residents in place, production lines running, food orders going out — installed without stopping any of it.

Your roof, your numbers

Every project here began with a free survey and an honest projection. Yours can too.
