Is Wales a good location for solar panels?
Solar performance potential across Wales
Wales benefits from reliable solar generation conditions. According to the Global Solar Atlas, the specific photovoltaic power output for Wales is approximately 932.7 kWh/kWp, confirming that solar systems perform effectively across the country.
Effective generation without direct sunlight
Despite Wales' well-known mix of weather, modern solar panels operate efficiently using daylight rather than direct sunlight. The country records a diffuse horizontal irradiation level of around 560 kWh/m², meaning panels continue to generate energy even on cloudy days common to the Welsh coast and valleys.
Reducing exposure to rising energy bills
With UK electricity prices remaining elevated, producing your own renewable energy is one of the most effective ways to reduce long-term energy costs and protect your home from future price rises.
All installers we work with are fully MCS-certified, so your system will meet SEG requirements.
Getting paid for excess solar energy
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.
Local authorities may offer additional support through community energy initiatives and sustainability programmes.
How widely solar is used in Wales
Wales has developed a strong and growing community of homeowners choosing clean, renewable electricity.
Solar installations across Welsh households
According to the Department for Energy Security & Net Zero, 111,191 domestic solar installations were operating across Wales as of September 2025. This demonstrates widespread confidence in solar technology as a long-term, cost-saving investment.
What a typical Wales solar system looks like
For a standard semi-detached or detached home, a typical solar installation ranges from 4 kW to 6 kW. Most households can expect costs of £6,000 to £10,000, depending on roof structure, panel type, and system design.

Frequently asked questions about solar panels in Wales
Do solar panels work in Welsh weather?
Yes. Modern PV (photovoltaic) technology works using daylight rather than heat or direct sunlight. Even on cloudy days, Wales' strong diffuse irradiation levels help ensure steady year-round generation.
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 system size, roof characteristics, and optional additions such as battery storage.
How long do solar panels last?
High-quality solar panels typically come with 25-year performance warranties. Many systems last 30 years or more with minimal maintenance, offering long-term financial returns.
Do I need planning permission for solar panels?
Most residential solar installations in Wales fall under Permitted Development, meaning no planning permission is required.
However, listed buildings, conservation areas, and World Heritage Sites may require additional permissions. A certified installer will advise you on the requirements for your property.
