Retail Solar Panel Installationsfor Stores and Multi-Site Estates

We have put solar on around 40 Aldi stores, 11 Sainsbury's, 10 Tesco and a 350kWp B&Q retail warehouse, all while the stores kept trading. If you look after one shop or a whole estate, we can survey, design and install to the same standard on every roof.

Repeat Work for the Big Names in UK Retail

Retailers only hand out repeat rollouts to contractors who deliver the same result store after store. These are programmes we have been trusted with.

Your Store Uses Power When the Sun Is Up

Fridges, freezers, lighting, tills and heating all run through trading hours, which is exactly when the panels generate. Most of what a store roof produces gets used on site, so it offsets electricity at the price you actually pay rather than being exported cheaply.

Daytime load matches generation
Refrigeration and lighting draw power all day, so self-consumption on a store is high and payback is quicker than on most buildings.
Big, simple roofs
Supermarkets and retail warehouses tend to have large, clear roofs with few obstructions, which keeps the design simple and the cost per kWp down.
Structural survey on every site
Trapezoidal, standing seam or built-up felt, we check the roof loading and pick the right mounting for each building, not just the first one.
Carbon reporting
Generation data from each store feeds straight into your sustainability and carbon reporting, site by site.

One Standard Across Every Store

Forty stores means forty roofs, forty structural checks and forty grid connections. What makes a rollout work is doing each one the same way, so your estates team is not chasing different answers from different sites.

  • One survey method so every proposal is comparable and you can prioritise the best roofs first.
  • One point of contact for the whole programme, with progress reported store by store.
  • Every DNO application handled, G98 or G99 depending on size, for each site.
  • Consistent handover packs with test certificates, MCS paperwork and monitoring set up per store.

How We Work Around a Live Store

Your customers should not notice we are there. This is how a retail install runs.

Survey
Roof and structural check, plus your half-hourly electricity data so the system is sized to what the store actually uses.
Design & DNO
System design, roof loading sign-off and the grid connection application to your network operator.
Install
Roof work planned around deliveries and the car park, with switchover done early or late so trading carries on.
Commission
Testing, sign-off, monitoring set up and a handover pack for your facilities team.

Planning More Than Panels?

Retail sites often add commercial EV charging in the car park or battery storage to use more of what the roof makes. For other building types, see our main commercial solar installation page.

Questions Retailers Ask Us

How much does solar cost for a supermarket or retail store?

Most commercial systems we fit work out at £600 to £900 per kWp installed, and the price per kWp drops as the system gets bigger. A typical 50kWp supermarket roof, the size we fit on Aldi stores, would land roughly between £30,000 and £45,000. We give you a fixed figure after a free survey of the roof and your half-hourly electricity data.

Does the store have to close while you install?

No. Every retail job we have done was installed with the store trading, including the 350kWp array on B&Q at Cribbs Causeway. We plan access, deliveries and any electrical changeover around your trading hours, and most switchover work is done early or late so customers never notice.

Can you roll solar out across lots of stores?

Yes, that is most of our retail work. We have fitted around 40 Aldi stores, 11 Sainsbury's stores in one programme, 10 Tesco stores and 6 Lok'nStore sites. You get one survey method, one design standard, one point of contact and reporting store by store.

We lease our store. Can we still have solar fitted?

Usually, yes, but you will need the landlord's consent and the lease should say who owns the panels and what happens at the end of the term. We can provide the roof survey, structural information and drawings your landlord or their agent will ask for.

Does each store need its own grid connection approval?

Yes. Each site is a separate connection, so each needs its own application to the local network operator under G98 or G99, depending on system size. We handle every application, the witness testing and the paperwork for each store.

Can you add EV charging in the car park at the same time?

Yes. We install commercial EV charging as well as solar, so we can plan both together and size the supply once. Our work includes a 21-bay workplace charging install for Iceland Foods at their Deeside head office.
