Farm & Agricultural Solar Panels in Sussex

Farm Solar for Sussex Growers

Few businesses feel energy costs like a working farm. Milking parlours, refrigeration and bulk milk tanks, grain drying, ventilation and lighting for poultry and livestock sheds, cold stores and irrigation all draw power through the day — exactly when the sun is shining. That makes agriculture one of the strongest cases for solar in the country, and Sussex’s mix of arable, dairy, livestock and poultry holdings is no exception.

Greener Solar Solutions designs and installs farm and agricultural solar across East Sussex, West Sussex and the wider South East. We put panels on barn and outbuilding roofs — or ground-mount where roof space is limited. As part of A Greener Alternative Ltd we have a long track record with Sussex homes and businesses, and we are MCS certified, NICEIC approved and TrustMark registered.

Why Solar Works So Well on Farms

  • Big, unshaded roofs — barns, cattle sheds and grain stores offer large, often south-facing roof areas, usually with no planning permission needed on an existing roof.
  • Daytime demand — farm loads run hard during daylight, so you use a high share of what you generate rather than exporting it cheaply.
  • High, rising bills — with grid electricity volatile and red-diesel relief gone, self-generated power gives cost certainty on a major input.
  • Diversification & resilience — surplus earns export income (SEG), and a battery keeps essential loads running through rural power cuts.
  • Tax-efficient — solar is plant and machinery; farm businesses can typically claim the Annual Investment Allowance / capital allowances. Ask your accountant.

Farms We Work With

  • Dairy — milking parlours, vacuum pumps and bulk tank cooling are steady daytime loads solar matches closely.
  • Poultry & livestock — ventilation, heating and lighting run around the clock; solar plus battery cuts a large slice.
  • Arable & mixed — grain drying and storage, workshops and irrigation, plus large barn roofs for bigger arrays.
  • Horticulture & vineyards — Sussex’s growing wine sector and glasshouse growers.
  • Equestrian & rural estates — stables, indoor schools and estate buildings.

Roof-Mounted or Ground-Mounted?

Most farm systems go on existing barn and shed roofs — the cheapest, simplest option, usually permitted development. Where roof space or orientation is limited, a ground-mounted array on unproductive land is an option; this normally needs planning permission, which we advise on and support. We recommend whichever gives the best return for your holding during the survey.

How Much Do Farm Solar Panels Cost?

Farm systems are priced per installed kilowatt-peak (kWp) and scale efficiently on large roofs. As a broad guide to typical UK installed pricing:

System size Typical farm use Indicative installed cost Rough annual saving*
10–30 kWp Small holding / single barn / workshop £8,000 – £30,000 £2,000 – £6,000
30–100 kWp Dairy / poultry unit / mixed farm £25,000 – £80,000 £6,000 – £18,000
100–250 kWp+ Large arable / multi-shed / estate £80,000 – £200,000+ £18,000 – £45,000+

*Savings depend on your load pattern, tariff and how much generation you use on site. Figures are approximate market ranges — we provide a modelled, fixed proposal after your free survey. VAT-registered farm businesses can normally reclaim VAT, so the 0% domestic rate does not apply.

Farm & Agricultural Solar FAQs

How much do farm solar panels cost?

Priced per kWp and scaling with size — roughly £8,000 for a small 10kWp barn array up to £200,000+ for a 250kWp+ multi-shed or estate system. We provide a modelled, fixed proposal after a free survey.

What is the payback on agricultural solar?

Because farms use so much power during daylight, payback is often among the fastest in solar — typically around 4–7 years, with panels producing for 25–30 years.

Do I need planning permission for solar on a barn?

Roof-mounted solar on an existing agricultural building is usually permitted development and needs no planning permission. Ground-mounted arrays normally do require permission — we advise and support the application.

Are there grants for farm solar?

Farm businesses can typically claim the Annual Investment Allowance / capital allowances against the cost, and rural energy grant schemes open periodically. Confirm tax specifics with your accountant.

Does solar work for dairy and poultry farms?

Yes — these have high, steady daytime loads (cooling, ventilation, lighting, heating) that solar matches very well, especially paired with a battery.

Can I add battery storage or generator backup?

Yes. A battery stores daytime surplus for evening loads and provides backup during the power cuts common on rural networks.
