Solar systems for logistics centres and warehouses

In warehouses and logistics centres there is often a gap between the roof area available and the electricity actually consumed. That gap is the starting point of the assessment, so it is examined before the scale of any project is discussed.

01
Why it fits

What is different about a logistics asset

These buildings behave differently from a factory. These three characteristics shape how the assessment is carried out.

Installation area available

Large flat roofs allow a comparatively straightforward layout, subject to load-bearing capacity and the structural loads involved.

Modest consumption relative to area

Consumption is usually low relative to the size of the roof. That calls for a deliberate decision about the surplus rather than an assumption of full coverage.

An income-producing asset

For an owner, generating electricity on site can affect the operating cost of the property and how attractive it is to tenants.

02
The challenges

The questions that come up in every logistics asset

These are the issues that determine the scale of the project, so they are examined at the first assessment.

A gap between roof area and consumption

The roof can support more generation than the site actually uses. The surplus is examined against the possible routes for using it and against connection limits.

Owner versus tenant model

The owner is sometimes not the consumer. The structure of the agreement between the parties determines who invests, who uses the electricity and who benefits from generation.

Load-bearing capacity of the roof

Wide flat roofs are not necessarily designed for additional load over many years. An engineering review of the structure and the fixings is required.

Traffic and logistics on site

Access routes, tall vehicles and day-to-day operations require a layout that does not obstruct the work or compromise the structure.

04
Considerations

Engineering and commercial considerations

On leased assets the commercial side often concerns one party to the agreement more than the other.

Engineering review

  • Load-bearing capacity and localised point loads on the roof
  • Fixings that do not damage the waterproofing or roof systems
  • Cable routing from the roof to the main switchboard
  • Obstruction of sightlines and access for tall vehicles
  • Limits of the existing connection capacity on site

Commercial review

  • How operating hours line up with generation hours
  • The structure of the agreement between owner and tenant
  • Capital cost against the expected lease term
  • The available routes for using surplus generation
  • Maintenance and cleaning costs over system life

On assets with multiple owners or under lease, it is worth reviewing the contractual aspects before detailed design. An initial assessment is not legal or tax advice.

How we work

Our delivery method on a logistics asset

On leased assets, defining the commercial model matters as much as the engineering review.

01

Initial conversation

Understanding the type of asset, the ownership structure, how electricity is used and what is expected from the project.

02

Mapping roof areas

Reviewing the roofs and ancillary structures, their age, the type of covering and the constraints that apply.

03

Consumption analysis

Bills and meter data, and an examination of the relationship between what the site consumes and what the roof could generate.

04

Reviewing the commercial model

Owner, tenant or both — defining who invests, who uses the electricity and who receives the benefit.

05

Feasibility and next steps

An initial view of feasibility, followed by detailed design, licensing, installation and operation.

06
What we need

What is worth preparing before the roof potential check

This basic information is enough to produce a useful initial view.

Approximate roof area and a description of the building type
Ownership details and tenant details, where applicable
Recent electricity bills for the consumer at the site
Information on existing roof systems
Operational constraints — traffic routes, access and storage
The expected term of engagement with the asset

Where the owner and the consumer are not the same party, the initial assessment will also consider how the benefit is shared between them.
