About This Location
Solar Panel Installation in Portsmouth
Portsmouth is England's only island city — built on Portsea Island in Hampshire — and the home of the Royal Navy, with a proud maritime heritage and a permanent connection to the sea that shapes both its character and its climate. Portsmouth is, by sunshine hours, one of the sunniest cities in the UK: the combination of a coastal south-facing position, maritime airflow, and southern latitude gives the city approximately 1,600 to 1,680 hours of sunshine annually — making it genuinely comparable with parts of the south-west coast. For solar panel installation, this exceptional sunshine profile translates directly into some of the best generation figures and fastest financial payback periods of any UK city. Portsmouth's housing stock is characterised by the dense terraced streets of Southsea, Fratton, and Kingston that cover much of Portsea Island — Victorian and Edwardian terraces that can be well-suited to solar installation where the rear roof has a south-facing aspect. The suburban areas north of the island — Cosham, Drayton, Farlington, and Waterlooville (just over the city boundary) — contain more conventional semi-detached and detached owner-occupier stock where installation is more straightforward. Portsmouth City Council has a climate action plan and has committed to net zero as a city; the council's social housing programme has included solar installations on some stock through ECO4 and predecessor schemes.
165 miles via M3/A3. One of the UK's sunniest cities — outstanding generation profile that delivers faster payback than anywhere north of the Humber.

FAQ
Solar Questions — Portsmouth
A typical residential solar panel system in the UK costs between £5,000 and £12,000 depending on system size, panel brand, and roof complexity. A standard 4kW system suitable for a 3-bedroom semi-detached house typically costs £6,000–£8,000 including installation and VAT at 0%.
Most UK homes need between 8 and 16 solar panels depending on energy usage and available roof space. A typical 3-bedroom house with average energy consumption usually suits a 4kW system (10 x 400W panels). We design every system based on your actual electricity bills and roof dimensions.
Yes. Solar panels generate electricity from daylight, not direct sunshine. On a cloudy day in the UK, panels typically produce 10–25% of their peak output. Over a full year in Yorkshire, a well-designed system generates 3,300–3,800 kWh — enough to cover 50–70% of an average household's electricity needs.
Most homeowners in Yorkshire see a payback period of 6–9 years based on current electricity prices and the Smart Export Guarantee. After payback, your solar panels provide essentially free electricity for their remaining 20+ year lifespan.
In most cases, no. Solar panels are classed as permitted development for domestic properties in England, meaning you do not need planning permission. Exceptions apply to listed buildings, conservation areas, and certain flat-roof installations. We check your specific situation during the free survey.
The Smart Export Guarantee pays you for excess solar electricity you export to the grid. Rates vary by energy supplier — typically 4–15p per kWh exported. You need an MCS-certified installation and a smart meter to qualify. We handle the SEG application as part of our service.
Modern solar panels are warranted for 25–30 years and typically continue generating electricity well beyond that. Performance degrades very slowly — most panels still produce 80%+ of their original output after 25 years. Inverters typically last 10–15 years and may need replacing once during the panel lifespan.
Yes. With electricity prices above 30p per kWh and 0% VAT on residential solar installations, the financial case is stronger than ever. A typical 4kW system saves £800–£1,200 per year on electricity bills plus SEG export payments, paying for itself in 6–9 years and then providing free electricity for 20+ more years.
