Solar Panels for Farms: A Complete Guide for East Anglia Farmers

East Anglia is home to some of the most productive farmland in England. From the Fenland arable fields of Cambridgeshire to the livestock operations of Norfolk and the mixed farms of Suffolk, agriculture is the backbone of the regional economy. It is also one of the most energy-intensive industries, making it perfectly suited to solar power.

Farm buildings offer ideal conditions for solar: large south-facing roof areas on grain stores, barns, and packhouses; high daytime electricity demand for irrigation, cooling, drying, and processing; and minimal planning complications on agricultural land.

Why Farm Solar Makes Financial Sense

Agricultural electricity rates in East Anglia typically range from 22-28p/kWh. A 50kW solar system on a grain store generates approximately 47,500-52,500 kWh per year, saving £10,000-£15,000 annually in displaced grid electricity. The payback period is typically 3-5 years.

Key financial advantages for farms include the Annual Investment Allowance allowing 100% tax deduction on solar installations up to £1M, 100% business rates exemption on rooftop solar until 2035, 0% VAT on all installations, and capital depreciation benefits.

Typical Farm Installations

Farm solar installations in East Anglia typically fall into these categories:

• Grain store roofs (30-100kW): The most common installation. South-facing corrugated steel roofs with clear access. Electricity offsets grain drying, ventilation, and general farm operations.
• Packhouse roofs (20-50kW): Fruit and vegetable packhouses have high cold storage electricity demands that align perfectly with solar generation peaks in summer.
• Barn conversions (4-10kW): Converted agricultural buildings used as offices or holiday lets can benefit from smaller residential-scale systems.
• Ground-mounted arrays (50-250kW): Where roof space is insufficient or unsuitable, ground-mounted systems on marginal land offer an alternative. These require planning permission but can be a productive use of lower-grade land.
• Dairy and poultry operations (20-80kW): Milking parlours, cooling tanks, and poultry house ventilation/heating have high and consistent electricity demands.

The Fenland Advantage

Fenland farms have a unique advantage for solar. The flat terrain means virtually zero shading from hills or elevated terrain. Many Fenland farms also operate energy-intensive drainage and irrigation pumping systems. Solar can offset a significant proportion of these costs.

The Soham Solar Farm (12MW) adjacent to Green Hat base, and the proposed Sunnica Energy Farm (500MW) near Isleham, demonstrate the regional solar potential on an industrial scale. Residential and commercial rooftop installations harness the same conditions on a smaller, more practical scale.

Case Study: 50kW on Grain Store Near Newmarket

We recently installed a 50kW system on a grain store near Newmarket. The installation comprised 120 high-efficiency panels mounted on the existing corrugated steel roof using non-penetrating clamps. The system generates approximately 47,000 kWh per year, covering the majority of the farm electricity demand. The projected payback period is 4 years, with annual savings of approximately £11,500.
