Commercial solar panel installers in Havant
Havant is the eastern anchor of the Portsmouth / Solent industrial belt — Langstone Technology Park (Pfizer, IBM, Colt Technology tenants) delivers the mature high-value technology footprint, New Lane Industrial Estate carries the light-manufacturing base (Kenwood's UK operations and adjacent white-goods supply chain), and Broadmarsh / Southmoor host the marine and coastal-industrial supply chain. PO9 sits inside the highest UK irradiance band and adjacent to the Solent Freeport designated area. SSEN's Havant 33 kV holds reasonable headroom following the 2023 Langstone reinforcement.
Best-fit sectors in Havant
- Langstone Technology Park pharmaceuticals and IT
- Kenwood / DeLonghi white-goods manufacturing

Do Langstone Technology Park pharmaceutical tenants have unusual PV requirements?
Yes — GMP-regulated production suites need strict harmonic-distortion and EMI-emission compliance on any DC/AC electrical addition. We specify Tier-1 inverters with IEEE-519 harmonic filtering and coordinate the G99 study with the site's GMP electrical qualification team.
Is Chichester Harbour SPA / Ramsar designation a PV constraint at PO9?
For rooftop arrays on New Lane / Langstone units no — the industrial footprint sits outside the SPA/Ramsar boundary and permitted development applies. Sites within 1 km of the harbour edge (Broadmarsh, parts of Southmoor) need a lightweight Habitats Regulations screening statement, which we handle.
How does SSEN handle PO9 G99?
The 2023 Langstone reinforcement opened meaningful headroom — sub-500 kWp G99 with export limitation typically clears in 8–10 weeks, and 1 MWp+ remains deliverable on Langstone Technology Park and New Lane feeders subject to network study.
Is Havant irradiance genuinely UK-leading?
Yes — the South Hampshire / west-Sussex coastal band delivers around 1,050–1,080 kWh per kWp per year, the highest commercial-solar yield anywhere in the UK, and cool Solent-adjacent ambient temperatures lift panel efficiency a further 2–3%.
How wide is Havant coverage?
Emsworth, Waterlooville, Hayling Island, Rowlands Castle, Denvilles and Bedhampton are day-one visits; Portsmouth, Chichester, Petersfield, Fareham and Gosport are on planned survey days from the PO9 base.
