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.

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