Solar Panels for Data Centres in Crawley

Serving Crawley and the wider West Sussex area, including Horsham, East Grinstead, Redhill.

Crawley — the Gatwick data corridor

Crawley is the primary data centre location south of London, anchored by Manor Royal Business District — the UK’s largest single business area by employment, covering 540 hectares on the western edge of Crawley adjacent to Gatwick Airport. Manor Royal hosts over 500 companies including Virgin Atlantic, Thales, Atkins Global, and a cluster of aviation, defence electronics, and technology firms with significant data infrastructure requirements.

The Manor Royal data centre market serves the Gatwick-corridor catchment: an arc from Guildford in the north-west through Crawley to Brighton in the east, encompassing a population of approximately 2 million and a commercial base dominated by aviation, professional services, retail, and hospitality. Gatwick Airport itself is one of the largest single data consumers in the region, running airport operations, baggage systems, biometric boarding, and real-time flight management from Manor Royal-adjacent data infrastructure.

Crawley’s data centre proposition is defined by three factors: proximity to London (35 miles on the M23, 30 minutes by Gatwick Express to London Bridge), the Gatwick Airport-driven connectivity and power infrastructure, and lower costs than London — commercial property rates in Manor Royal are 40–60% below equivalent London locations.

Manor Royal — the data centre opportunity

Manor Royal Business District is managed as a Business Improvement District (BID) by the Manor Royal BID company, which has been pursuing sustainability certification across the estate. The BID’s sustainability programme includes a collective energy procurement scheme, a solar PV advisory service for estate members, and an estate-wide carbon reduction target aligned with Crawley Borough Council’s net zero plan.

Buildings in Manor Royal are predominantly 1960s–1980s industrial and office development, with a mix of heritage stock and modern redevelopment. Many data facilities occupy converted industrial buildings — large-span steel portal structures with profiled steel or asbestos cement roofing. Modern Manor Royal development (post-2010 construction) uses flat membrane or profiled steel roofing suitable for direct PV installation.

For heritage buildings with asbestos cement roofing, we provide combined re-roof + PV proposals. The PV business case often contributes meaningfully to the re-roof cost recovery, particularly at Manor Royal’s elevated grid rates (UK Power Networks South East zone, 23–27p/kWh for large I&C customers).

Gatwick Airport and aviation data infrastructure

Gatwick Airport’s technology infrastructure is extensive. The airport’s IT operations centre manages real-time passenger flow, check-in systems, baggage reconciliation, airfield management, and biometric boarding for over 45 million passengers per year. Aviation data is exceptionally demanding: high throughput, ultra-low latency, and near-100% availability requirements (even a brief outage during peak operations could affect thousands of passengers).

Solar PV for Gatwick-adjacent data facilities must address:

• Aerodrome safeguarding (CAA/HAL consultation required for rooftop PV within safeguarding area)
• Glare assessment (potential for reflected sunlight to affect aircraft on Gatwick’s southern approach)
• Power quality requirements (aviation operations require very stable power)

We manage the aerodrome safeguarding consultation as standard on all Crawley/Gatwick-adjacent projects. For facilities within 3 km of the runway threshold, a photometric glare assessment is standard.

Crawley solar economics — the South East advantage

Crawley and West Sussex receive approximately 1,650 hours of sunshine per year — among the highest in England, reflecting the South Coast’s favourable climate. This is significantly more than Manchester (1,395 hours) or Edinburgh (1,350 hours). A 400 kW Crawley data centre rooftop system generates approximately 375,000 kWh per year.

At UK Power Networks South East zone grid rates of 24p/kWh, annual savings of £90,000. Capital cost: £385,000–£460,000. Simple payback: 4.3–5.1 years — among the shortest in the UK outside of the Slough corridor, reflecting the combination of high irradiance and high grid rates.

UKPN — Crawley connection process

Crawley is served by UK Power Networks (South East area). Connection timescales:

• G98 (below 50 kW): self-certification
• G99 (50 kW–1 MW): 65 working-day study
• G99 extended (above 1 MW): 6–12 months

Manor Royal Business District has good primary substation capacity from UKPN’s Manor Royal grid supply. Zero-export designs face minimal technical complexity in this area.

Frequently asked questions about Crawley data centre solar

What is the Gatwick aerodrome safeguarding process for Manor Royal PV? We submit a safeguarding notification to Gatwick Airport Ltd (GAL) for all PV installations within the Gatwick aerodrome safeguarding area. GAL responds within 28 days in most cases. For flat-roof arrays below 2 m mounting height, safeguarding objections are rare. Taller mounting systems or systems with unusual geometries may require a photometric glare study, which we commission from specialist consultants.

Does Crawley’s high solar irradiance significantly improve payback vs other UK cities? Yes — materially. Crawley generates approximately 15–20% more annual kWh per kW of installed PV than Manchester or Edinburgh. At the same grid rate, this directly improves annual savings by 15–20% and reduces payback by 0.5–1.0 years. For a 400 kW system, this represents approximately £13,500 additional annual saving compared to a Manchester equivalent — significant over a 25-year project life.

Can Manor Royal historic buildings (pre-1980 stock) support rooftop PV? Many can, with appropriate structural assessment. For buildings with asbestos cement roofing, a combined re-roof + PV approach is our standard recommendation. We include a structural desk study in our feasibility process and commission a full structural survey before design sign-off.

Thales, Virgin Atlantic, and aviation data security

The defence electronics and aviation sector in Manor Royal creates specific data centre security requirements that are unusual outside of central London. Thales UK’s Manor Royal facility — one of their largest UK engineering centres — runs classified defence electronics programmes that require BPSS, SC (Security Cleared), and in some cases DV (Developed Vetting) cleared personnel for data centre access. Virgin Atlantic’s Manor Royal headquarters runs flight operations data, crew management systems, and passenger booking infrastructure.

Solar PV installation on sites hosting cleared personnel and sensitive data requires the same security clearance standards as the facilities themselves. Our standard BPSS-cleared crew requirement maps precisely onto the Manor Royal environment. For sites requiring SC-cleared personnel access, we can manage the SC clearance process for lead engineers — this typically adds 6–8 weeks to project mobilisation but ensures that access requirements do not restrict the project programme.

The aviation data infrastructure at Manor Royal — including Thales’s air traffic management systems and airline operations centres — runs 24/7 at near-100% utilisation. This is the ideal load profile for solar self-consumption. We have delivered G99-commissioned systems for aviation sector data facilities, including managing the specific challenges of aerodrome safeguarding and the power quality requirements of aviation electronics.

Financial model for a Crawley data centre installation

Using the representative scenario (420 kW system, Manor Royal, 2025):

A post-tax payback of 3.8 years and an IRR of 23% make Crawley one of the two or three most financially compelling data centre solar locations in the UK (alongside Slough and the Isle of Wight). West Sussex’s 1,650 hours of annual irradiance — the highest of any location in our 20-location portfolio — combined with UKPN South East’s premium grid rates produce exceptional economics. Asset finance at 6.5% APR over 5 years: monthly repayments of ~£7,300 against monthly savings of ~£7,760 — immediately cash-positive from month 1.

Aerodrome safeguarding: the process in detail

Gatwick aerodrome safeguarding is managed by Gatwick Airport Ltd (GAL) on behalf of the Civil Aviation Authority (CAA). Safeguarding requirements apply within a defined zone around the airport — covering all of Manor Royal Business District and most of Crawley. Any permanent structure (including solar PV panels) within the safeguarding zone requires notification to GAL before installation.

Our safeguarding notification process:

1. We prepare a safeguarding submission document covering the proposed installation’s grid reference, panel height above ordnance datum, panel area, and tilt angle.
2. We submit to GAL’s safeguarding team (typically via Aerodrome Safeguarding UK’s online portal).
3. GAL responds within 28 days in most cases — typically confirming no objection for flat-roof arrays with panels below 2 m mounting height.
4. Where GAL identifies a potential glare or obstruction concern, we commission a photometric glare assessment from a specialist consultant (cost: £1,500–£3,000). In our experience, these assessments almost always confirm no interference with approach paths when panels are correctly oriented (typically south-facing, maximum tilt 15° on flat roofs).

We have completed 8 safeguarding notifications for Manor Royal installations to date. None has resulted in a permanent refusal. The process adds approximately 4 weeks to project programme but is entirely manageable within our standard project timeline.

Manor Royal BID sustainability programme

The Manor Royal Business Improvement District (BID) has been developing a collective sustainability programme for the estate since 2022. The BID’s carbon reduction targets are aligned with Crawley Borough Council’s net zero plan and include:

• An estate-wide carbon footprint baseline (completed 2023)
• A collective renewable energy procurement advisory service
• An energy efficiency grant programme for SME members (funded from BID levy)
• A Scope 2 reduction reporting framework for larger members

Data centre operators on Manor Royal who install solar PV and register their generation with the BID’s collective carbon tracking programme contribute to the estate’s aggregate carbon reduction — a useful differentiator in BID membership documentation and in marketing to sustainability-conscious customers who value the collective Manor Royal sustainability narrative.
