Is Swansea a good location for solar panels?
Solar energy potential in Swansea
Swansea benefits from excellent solar generation conditions. According to the Global Solar Atlas, the specific photovoltaic power output for Swansea is approximately 1,027.3 kWh/kWp, placing it among the stronger regions in Wales for solar energy.
Year-round generation in cloudy conditions
Despite Wales’ changeable weather, modern solar panels operate efficiently using daylight rather than direct sunlight.
Swansea has a diffuse horizontal irradiation level of 572.5 kWh/m², representing the scattered light that reaches solar panels on cloudy days. This enables consistent, year-round energy production.
Reducing long-term household energy costs
With UK electricity prices remaining high, producing your own renewable energy is one of the most effective ways to reduce long-term costs and protect your household from future price rises.
Exporting surplus electricity through SEG
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 support schemes
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 councils may offer additional support through community energy initiatives and sustainability programmes.
