Solar Panels for Farm Buildings in Pembrokeshire

Solar panel installation costs for farm buildings in Pembrokeshire typically range from £30,000 to £250,000+ depending on system size and building type. Smaller installations on single barns or sheds start from around £30,000–£60,000, while large-scale multi-building systems for arable or dairy operations can exceed £200,000. We offer free site assessments and competitive pricing for Pembrokeshire farmers, with various financing options including Power Purchase Agreements with zero upfront costs.

In Pembrokeshire and across Pembrokeshire, we install solar panels on all types of agricultural buildings. This includes grain stores, cattle sheds, dairy barns and milking parlours, poultry houses, machinery stores, lambing sheds, and general-purpose farm buildings. We also design ground-mounted systems for farms where rooftop installation isn't suitable. Our surveyors assess structural integrity, roof pitch, and orientation before recommending the best solution.

In most cases, solar panels on agricultural buildings in Pembrokeshire qualify as permitted development and do not require full planning permission, provided the installation meets permitted development criteria — typically systems under 1MW on agricultural land. However, if your farm is in a National Park, Area of Outstanding Natural Beauty, or a listed building is involved, different rules may apply. Our team is familiar with Pembrokeshire planning guidelines and will handle all relevant pre-application checks for your Pembrokeshire installation.

Yes. Through the Smart Export Guarantee (SEG), Pembrokeshire farm operators can earn payments for surplus electricity exported to the National Grid. SEG rates vary by energy supplier and are typically between 3p–15p per kWh. On a large agricultural system generating 200,000+ kWh per year, export earnings can contribute several thousand pounds annually. Most farm solar systems are sized to maximise self-consumption first, since using your own generation (worth 25–35p/kWh) is more valuable than exporting at lower SEG rates.

Most farm building solar installations in Pembrokeshire are completed within 1–3 weeks from permit approval, depending on system size. Smaller single-building installations can often be completed in 3–5 working days. We work around your farming schedule to minimise disruption and can coordinate with your Pembrokeshire grid operator (DNO) for connection applications, which typically take 4–8 weeks for larger installations.

Pembrokeshire farmers can access several funding streams for agricultural solar. The Farming Investment Fund (FIF) Productivity and Infrastructure Grant covers eligible renewable energy equipment. The Smart Export Guarantee (SEG) provides ongoing payments for surplus electricity exported to the grid. Welsh farmers can access the Welsh Government's Rural Investment Scheme and TESS grants for renewable energy. Our team provides a full grant assessment as part of every free site survey.

Winter solar generation in Pembrokeshire is lower than summer but remains meaningful. A 50 kWp system in this region typically generates 8,000–12,000 kWh in December and January combined, compared to 20,000–25,000 kWh in May and June. South-facing roofs in Wales capture winter sun at low angles effectively with correctly pitched arrays. Year-round, your system will produce roughly 800–1,000 kWh per kWp installed annually. We model seasonal generation curves for every Pembrokeshire installation so you have a realistic expectation of performance in all months.
