Why commercial is different

Your load curve is the whole story

A business draws its heaviest load between 8am and 6pm — precisely when a solar array produces. Self-consumption of 70–90% is normal on a commercial site, against 40–50% for a home. Every unit consumed on site offsets your full commercial import rate, and that is what drives the return.

So we start with your half-hourly data, not your roof plan. The array is sized to the load, the export limit is designed around the DNO's constraints, and the financial model is built on your actual tariff rather than a national average.

Our engineers came out of utility-scale renewables — 10 MW solar farms and 50 MW battery sites — so commercial documentation, CDM duties and DNO negotiation are routine rather than a stretch.

Sectors we work in

Built for working buildings

🏭

Industrial & warehousing

Large uninterrupted roof spans and steady daytime load — the strongest payback profile we see.

🏢

Offices & retail parks

Weekday demand matched to generation, plus a visible sustainability story for tenants and customers.

🚜

Farms & rural estates

Barn roofs and ground-mount arrays, often paired with storage where the grid connection is constrained.

🏫

Schools & public sector

Framework-friendly delivery, out-of-hours installation and clear reporting for governors and funders.

What's included

A commercial scheme, not a domestic one scaled up

Scale
50 kWp to multi-MW. Our team has managed 10 MW solar farms and 50 MW BESS sites — commercial rooftops are well within our comfort zone.
Grid
Full G99 application management, export limitation design and liaison with the DNO on constrained connections.
Structural
Roof structural appraisal and wind-load calculations before a single rail goes up, on both pitched and flat/ballasted systems.
Financial
Modelled generation, self-consumption and cash flow — plus capital allowance data your accountant can use.
Delivery
RAMS, CDM compliance, site inductions and phased works so your operation keeps running.
Aftercare
Monitoring, O&M options, and performance reporting against the modelled yield.

The process

From data to commissioning

Desktop feasibility

We model your roof, half-hourly consumption data and tariff to size the array properly — before anyone visits.

Site survey & structural

Access, roof condition, structural capacity and switchroom assessment.

Proposal & finance

Full financial model: CAPEX, generation, self-consumption, payback, IRR and capital allowances. PPA option if preferred.

G99 & delivery

We submit and manage the DNO application, then install and commission around your operating hours.

Questions

Commercial solar FAQs

What size system does my business need?

It is driven by your half-hourly consumption data, not your roof size. We size the array to maximise self-consumption first, because every unit you use on site is worth far more than an exported one.

How long is the payback?

Four to seven years is typical where there is strong daytime load. Sites that run plant or refrigeration through the day sit at the shorter end.

Will installation disrupt operations?

Rarely. Most of the work happens on the roof, with short planned outages for the electrical tie-in — usually scheduled out of hours or at a weekend.

Can we do this without capital outlay?

Yes. A power purchase agreement lets a funder own the asset while you buy the electricity at a fixed, lower rate. Lifetime return is lower than buying outright, and we will show you both models.

Do you also install commercial battery storage?

Yes. Battery storage on a commercial site can cut peak demand charges as well as store surplus generation — often the difference between a good scheme and a great one. Where it makes sense, we can also connect your system to Simtricity Flux so your battery earns from grid services and dynamic tariffs instead of sitting idle.
