Solar Carports in Portsmouth

Why Portsmouth is a Strong Solar Carport Market

Portsmouth is the principal city in South East, with a resident population of 208,100 and a sprawling commercial estate centred on Lakeside North Harbour, Port Solent, Portsmouth Naval Base, Voyager Park, Airport Service Road. Annual solar irradiance of 1075 kWh/m² (recorded at the nearest Met Office reference station) places Portsmouth in the upper tier of UK solar yield for commercial solar. A 1.5 kWp per-bay solar carport in Portsmouth generates approximately 1290 kWh per parking bay per year — meaning a 200-bay carport produces around 258,000 kWh annually.

At current commercial electricity rates of 45-50p/kWh in the South East region, a 200-bay Portsmouth solar carport (~300 kWp) saves approximately £94,000-£103,000 per year on electricity bills, with a typical simple payback of 4-7 years and after-AIA payback of around 3-4 years.

Portsmouth Council Climate Framework

Portsmouth City Council operates under the Portsmouth Climate Change Strategy 2030, with a published net zero target of 2030 — one of the most aggressive in the UK. The framework explicitly identifies commercial-scale solar (including car park canopies) as a priority intervention. Planning applications for solar carports are typically determined within 8-12 weeks; we maintain a 100% planning approval record across all Portsmouth and South East projects.

Portsmouth City Council is Solent-leading on EV deployment (BP Pulse, Osprey hub). Naval Base estate, Gunwharf Quays, QA Hospital all carport candidates.

Industrial Areas and Target Sites

The principal commercial parking estates in Portsmouth that are well-suited to solar carports include the industrial and business areas of Lakeside North Harbour, Port Solent, Portsmouth Naval Base, Voyager Park, Airport Service Road. Each typically combines high-density car parking with the kind of medium-voltage grid infrastructure that makes large carport projects (300+ kWp) practical.

Portsmouth Solar Carport Case Reference

A representative Portsmouth-area solar carport project: 275kWp / 220 spaces / £118,000 annual saving. Typical project profile for Portsmouth sites includes 100% AIA capital relief, OZEV WCS grant for workplace EV chargers (up to £14k), and full design-and-build delivery within 22-28 weeks. We staff every Portsmouth project from our regional team — site visit, structural survey, planning consultation and commissioning all handled by named local engineers.

Grid Connection and DNO for Portsmouth

Portsmouth sits within the UK Power Networks licensed distribution area. G99 grid connection applications for commercial solar carports of 100 kWp-1 MWp typically receive offer within 65 working days at standard fees; larger projects (1-5 MWp) typically 90-130 working days. For sites above 5 MWp, a more complex (and longer) G99/G100 connection process applies — typically 6-18 months including any necessary upstream reinforcement.
