Is Southampton a good location for solar panels?
Solar performance potential in the city
Southampton benefits from some of the highest solar irradiation levels in the UK. According to the Global Solar Atlas, the specific photovoltaic power output for Southampton is approximately 1,064.5 kWh/kWp, offering excellent performance for residential solar systems.
Effective generation without direct sunlight
Despite variable coastal weather, modern solar panels operate efficiently using daylight rather than direct sunlight.
Southampton has a diffuse horizontal irradiation level of 585.3 kWh/m², representing the scattered sunlight that still reaches the ground on overcast days, ensuring consistent year-round energy production.
Reducing exposure to rising energy bills
With UK electricity prices remaining elevated, producing your own renewable energy is one of the most reliable ways to reduce long-term energy costs. A well-designed system can offset a significant share of your household consumption.
Getting paid for excess solar energy
All installers we work with are fully MCS-certified, so your system will meet SEG requirements.
Homeowners can earn payments for surplus electricity fed back into the National Grid through the Smart Export Guarantee (SEG) scheme. To be eligible, your installation must be commissioned by an installer certified by the Microgeneration Certification Scheme (MCS) or an equivalent body such as Flexi-Orb.
Tax reliefs and local incentives
Solar panels benefit from 0% VAT on installation, helping lower upfront costs. This tax relief runs until March 2027, making now a good time to take advantage of the saving.
Some local councils in the South Coast region also offer sustainability grants or community energy initiatives that can further support homeowners.

Frequently asked questions about solar panels in Southampton
Do solar panels work in UK weather?
Yes. Modern PV (photovoltaic) technology works using daylight rather than heat or direct sunshine. This means panels continue generating electricity on cloudy days, making them well-suited to Southampton’s coastal climate.
How much does a solar panel system cost?
Most residential solar panel systems cost between £6,000 and £10,000.
The final price depends on the system size and the complexity of your roof installation. Multiple roof angles, difficult access, or scaffolding requirements may increase installation costs.
How long do solar panels last?
High-quality solar panels typically come with 25-year performance warranties. In practice, many systems last 30 years or more with minimal maintenance, providing decades of reliable energy production.
Do I need planning permission for solar panels?
In most cases, installing solar panels on a residential roof in Southampton falls under Permitted Development, meaning no planning permission is required.
However, listed buildings and conservation areas may have additional requirements. A certified installer will advise you on any property-specific regulations.
