Solar PV for Business

Commercial Solar PV

Cut Operating Costs With Commercial Solar

Electricity is one of the largest controllable overheads a business carries. A commercial solar PV system turns your roof or unused land into a long-term, low-maintenance generating asset — producing clean power on-site where you use it, insulating you from volatile grid prices, and strengthening your environmental credentials. As MCS-accredited installers based in Preston, we design, install and commission commercial systems for businesses right across Lancashire and the North West. Pair it with commercial battery storage to store daytime generation and shift it to peak periods.

Why Businesses Choose Solar

A commercial PV system is an investment in your balance sheet as much as your sustainability.

Lower Running Costs
Generate your own electricity during working hours and cut the amount you buy from the grid at commercial rates.
Price Certainty
Hedge against rising and unpredictable energy prices with a predictable, decades-long cost of generation.
ESG & Net Zero
Demonstrate measurable carbon reduction for tenders, reporting and customers who expect a green supply chain.
Productive Roof Space
Put otherwise unused roof or land to work as a revenue-protecting asset, with surplus exportable to the grid.

Systems Engineered Around Your Operation

Every commercial site is different — roof type and orientation, three-phase supply, half-hourly load profile and future expansion plans all shape the design. We survey your premises, model your generation against your actual consumption, and engineer a system that maximises self-consumption rather than simply filling the roof. From a single industrial unit through to multi-array installations, our team handles the full scope in-house.

  • Pitched, flat-roof and ground-mounted arrays
  • Single and three-phase commercial inverters
  • Optimisers & panel-level monitoring for shaded roofs
  • G99 DNO applications managed on your behalf
  • Integrated battery storage & EV charging

Sectors We Serve

Daytime-heavy energy users see the strongest returns from solar — but almost any business with roof or land can benefit.

Warehousing & Logistics
Large, unshaded roof spans are ideal for high-output arrays that power lighting, conveyors, chillers and forklift charging.
Manufacturing & Industrial
High, steady daytime demand from machinery means generation is consumed on-site where it offsets the most expensive units.
Agriculture & Farming
Barn and outbuilding roofs and field-edge ground mounts power refrigeration, milking, irrigation and grain drying.
Offices & Workspaces
Generation aligns neatly with 9-to-5 occupancy, IT loads and air conditioning, supporting net-zero and BREEAM goals.
Retail & Hospitality
Refrigeration, lighting and HVAC run all day — solar trims those costs while showcasing green credentials to customers.
Public & Community
Schools, leisure centres and community buildings cut budgets and create a visible, teachable sustainability statement.

Recent Larger-Scale Installations

From rooftop commercial arrays to high-capacity systems — including a 120kW solar PV and 200kWh battery installation, our largest to date.
