Use large roof assets
Turn otherwise unused warehouse roof space into on-site electricity generation.
Solar panels for warehouses and logistics operations
Warehouse solar turns large roof areas into working energy assets. We design systems around distribution-centre demand, landlord and tenant responsibilities, fleet charging and future electrification.
Why logistics operators are installing warehouse solar
Large roof planes and daytime electricity demand can make warehouses strong candidates for solar. The best design accounts for operations, leases, roof warranties and future fleet charging.
Lower site overheads
Offset grid use for lighting, conveyors, offices, refrigeration and handling equipment.
Prepare for electric fleets
Coordinate generation with future depot and staff vehicle charging demand.
Support ESG reporting
Metered renewable generation supports credible occupier and property reporting.
Improve energy resilience
Storage and controls can help manage peaks and constrained connections.

Is your warehouse roof suitable for solar panels?
Metal, membrane and composite-panel roofs can all be candidates. Usable capacity depends on structure, condition, warranty, fire strategy and roof obstructions.
What we assess
- Structural capacity and remaining roof life
- Roof covering, fixing method and warranty
- Rooflights, vents, smoke controls and safe access
- Metering, switchgear and grid capacity
Landlord, tenant and insurer requirements
Ownership and consent should be clear before detailed design. We account for lease terms, repairing obligations, roof warranties, insurer requirements and how the installation will be treated at lease end.
Warehouse solar by logistics site type
A cold store has a different energy profile from a parcel hub or ambient warehouse. We use operating data to match the system to the site.
Distribution centres
Lighting, conveyors and long operating hours can support high self-consumption.
Cold storage
Refrigeration creates substantial, consistent demand across the year.
Parcel hubs
Sorting equipment and extended shifts can use generation directly.
Logistics parks
Multi-building estates may support phased or landlord-led installations.
Fleet depots
Solar, storage and charging can be planned as one energy system.

Solar solutions suited to warehouses and depots
Rooftops usually provide the greatest opportunity, while carports, batteries and chargers can support wider site plans.
Warehouse rooftop solar
Large, low-pitch roofs can accommodate significant arrays close to operational loads. Structural capacity, roof condition and fire-safety zones determine the usable layout.
Solar carports and fleet charging
Carports add generation where roofs are constrained and place power close to charging bays. Load management helps coordinate chargers with the building and grid connection.
Rooftop solar
or solar carports for logistics?
The two approaches can work separately or together across larger depots and logistics parks.
| Consideration | Warehouse rooftop | Solar carport |
|---|---|---|
| Best suited to | Large sound roof planes | Parking or fleet yards |
| Operational space | No ground area required | Retains vehicle space beneath |
| Fleet charging | Feeds chargers through site network | Generation positioned near bays |
| Key checks | Structure, warranty and fire strategy | Traffic, impact protection and planning |
Battery storage for warehouses and logistics
Storage can move surplus solar, manage peak demand and support charging where the data shows a clear operational and financial benefit.
Where storage can help
- Evening and overnight warehouse shifts
- Refrigeration and cold-store demand
- Short peaks from conveyors or chargers
- Sites with constrained export capacity
How we size storage
We model half-hourly demand, solar output, tariffs, export value and planned charging. Backup requirements need separate design because ordinary grid-connected storage does not automatically keep a depot operating during an outage.

Illustrative warehouse solar costs, savings and payback
These broad examples show how roof capacity and on-site use can shape a warehouse solar investment.
| System size | Typical setting | Indicative installed cost | Illustrative annual saving | Indicative payback |
|---|---|---|---|---|
| 50–100 kWp | Small warehouse or depot | £45,000–£90,000 | £12,000–£28,000 | 4–7 years |
| 100–250 kWp | Distribution centre | £85,000–£200,000 | £25,000–£65,000 | 4–7 years |
| 250–500 kWp | Large warehouse or cold store | £190,000–£375,000 | £55,000–£130,000 | 4–8 years |
| 500 kWp+ | Logistics park or major hub | Site specific | Site specific | Site specific |
Figures are illustrative estimates, not quotations or guaranteed returns. Actual costs, savings and payback depend on site conditions, electricity tariffs, on-site consumption, export value, finance, grid requirements and final system design. Tax treatment depends on your circumstances; seek advice from your accountant.
Leases, roof warranties and grid connection
Warehouse projects often involve several stakeholders. Aligning property, operational and electrical requirements early helps avoid delay.
Property and operational considerations
We identify landlord consent, lease obligations, roof warranties, insurer requirements, fire strategy, access routes and any interaction with roof replacement plans.
Connecting generation and chargers
The network operator confirms import and export capacity. Solar, battery storage and fleet charging should be assessed together where electrification could materially change future demand.

Warehouse solar
in practice
A strong logistics design balances roof capacity with the electricity the occupier can use, now and as fleet charging expands. Ownership and lease responsibilities are addressed alongside the technical design.
Your proposal uses site-specific data and survey findings. Illustrative examples and other projects are not treated as guaranteed performance.

Frequently asked questions
Can solar panels be installed on a metal warehouse roof?
Often, yes. The fixing method depends on the roof profile, condition, structure and warranty. These are checked before the design is finalised.
Who owns warehouse solar panels, the landlord or tenant?
Ownership depends on the lease and funding structure. Landlord consent and responsibilities for maintenance, insurance and lease end should be agreed before installation.
Will installation disrupt warehouse operations?
The programme is planned around loading bays, vehicle routes and shifts. Most roof work can take place above operations, with any electrical shutdown agreed in advance.
Can warehouse solar support fleet charging?
Yes, but charging demand, vehicle dwell times and grid capacity should be modelled together. Load management and batteries may help on constrained sites.
Is battery storage worthwhile for a distribution centre?
It can be where operations continue outside solar hours, demand peaks are costly or export is constrained. Interval data is essential to test the case.
What if the warehouse roof needs replacing?
Reroofing or major repairs are usually best coordinated before solar installation to protect warranties and avoid removing and reinstalling panels later.
Do warehouse solar panels need planning permission?
Some rooftop systems may qualify as permitted development, subject to conditions. Carports, ground-mounted systems and constrained sites may need an application.
What happens to surplus warehouse solar electricity?
Surplus can be exported, stored or used for flexible loads such as charging. The system is normally sized to prioritise useful on-site consumption.
How are large warehouse systems maintained?
Remote monitoring identifies unusual performance. Planned inspections, electrical testing and condition-led cleaning support safe operation.
