Commercial solar

The cheapest power your site will buy is on its own roof.

We design, install and finance rooftop, carport and ground-mount solar for businesses across northern Europe, sized to your meter data so the power is used where it is made.

01How it works

Where solar fits on your site.

Every system we build connects to the same switchboard, so solar, storage and charging are designed together, against one grid connection.

01

Panels turn daylight into direct current

Modules on the roof, a carport or open ground produce direct current whenever there is daylight, most strongly between late morning and mid-afternoon.

02

Inverters feed the main switchboard

String inverters convert it to alternating current at the voltage your site runs on and connect into the main switchboard, beside the grid supply.

03

Your site uses solar first

Machines, lighting, cooling and chargers draw from the array before the grid. You buy less power at the price you pay today.

04

Surplus goes to a battery or the grid

What the site cannot use charges a battery or is exported and paid for by your supplier. Monitoring records every 15 minutes.

02Who it suits

The sites that gain most.

If your site is on this list, a site assessment will usually find a system that pays for itself.

  • Logistics and warehousing

    Large flat roofs and steady daytime loads from lighting, sorters and cooling.

  • Manufacturing

    High, constant demand that uses almost every kWh the roof makes.

  • Retail

    Cooling and lighting that peak on the same sunny afternoons as solar.

  • Agriculture

    Barn and store roofs with milking, ventilation and cold storage below.

  • Education

    Daytime use on weekdays, with carports and roofs that stay in use for decades.

03Key figures and specs

What we build, in numbers.

The ranges we design within. Your proposal names the exact equipment and why it was chosen.

04The process

Five steps, one team.

01

Site assessment

A year of meter data, the roof drawings and a two to three hour visit.

02

Design and yield model

Panel layout, shading study, structural check and a yield model you can test.

03

Permits and grid

Building notifications and the network operator's approval, handled by us.

04

Installation

Our own crews, scheduled around your operations and deliveries.

05

Monitoring and service

Commissioning report, then 25 years of data, alerts and visits.

StorageBatteries that keep your midday surplus, cut peaks and back up critical loads.EV chargingDepot, workplace and visitor charging, managed so your connection copes.

Most modern warehouse and factory roofs can. We check the structural drawings and, where needed, ask a structural engineer to confirm before anything is designed. If the roof needs replacing within ten years, we tell you first.

Site assessment

Find out what your roof could produce, and what it would save.

An engineer reviews your meter data and roof, visits the site and sends a written proposal with a design, a yield model and the financing options that fit. It costs nothing and commits you to nothing.
