Commercial solar — NI

Turn a fixed overhead into an asset.

Your business buys electricity at the exact hours solar produces it. A commercial array on your roof cuts that bill from day one, hedges you against price rises, and keeps working for decades. Designed and installed by NICEIC-approved electricians.

The business case

Businesses are better suited to solar than houses.

Homes use power in the evening; businesses use it 9-to-5 — while the sun's out. That match is why commercial systems typically pay back faster.

  1. 9-to-5 is peak sun

    Daytime match

    Refrigeration, machinery, computers and lighting all run while panels generate. More self-use means faster payback.

  2. Your own tariff

    A price you control

    Every unit you generate is a unit you don't buy at whatever the market does next. Solar output is the one tariff that never rises.

  3. Tenders & supply chains

    Credentials that count

    Customers and contracts increasingly ask about carbon. A roof of panels is the visible, measurable answer.

Who it's for

If you've got a roof and a daytime bill, it's for you.

  • Offices and professional units. Steady 9-to-5 loads that map straight onto the generation curve.
  • Retail and hospitality. Refrigeration and lighting run all day, every day — solar eats straight into it.
  • Light industrial and workshops. Big steel roofs were practically designed for panels.
  • Fleets going electric. Pair the roof with workplace chargers and fuel the vans on sunshine.

The numbers

Your roof is unpriced stock. Sell it to yourself.

Commercial electricity in Northern Ireland is bought at day rates precisely when solar generates. Every kilowatt-hour made on the roof is one not bought at peak price — the maths is unusually short.

Costs that stop moving

A commissioned array fixes the cost of a slice of your consumption for twenty-five years. Budgets stop flinching every time the market does — a hedge your accountant will actually like.

Allowances that stack

Solar qualifies for capital allowances against corporation tax, and the installation carries 0% VAT where eligible. We provide the cost breakdown your accountant needs to claim cleanly.

ESG you can point at

Tenders and supply chains increasingly ask for carbon numbers. Metered generation data gives you real figures for reporting — not offsets bought from a spreadsheet.

Delivery

Installed around your operation, not through it.

Warehouses, factories, offices, retail — each install is programmed around the business: crane lifts and roof work sequenced with your operations manager, DC runs kept clear of production areas, and shutdowns for connection agreed in advance and kept short. Commissioning includes monitoring set up for your facilities team, with alerts if a string ever underperforms — so the system keeps earning quietly for decades.

  • RAMS, insurance and site inductions — commercial paperwork done properly
  • Per-string monitoring with fault alerts from day one

Straight answers

Commercial solar, answered honestly.

Does commercial solar make sense for a small business?

If you use electricity during the day — machinery, refrigeration, computers, lighting — then usually yes. Businesses use power exactly when panels produce it, which is why commercial payback is often faster than domestic.

Will the installation disrupt trading?

Most of the work happens on the roof. The electrical connection is planned around your quiet hours — early morning, a weekend, whatever suits — so downtime is minutes, not days.

What about the grid connection paperwork?

We handle the full G99 application to NIE Networks as part of the job — commercial systems need approval before energisation, and we prepare, submit and chase it so it never becomes your problem.
