Solar Panels for Farms in Shetland

An independent guide to solar on farms in Shetland and the wider Shetland Islands area, including Orkney, Faroe Islands, Caithness: what it costs, the planning rules, the grid and the funding position, from official sources.

Agricultural solar panels in Shetland

Agricultural solar panels in Shetland answer a problem that few mainland farms ever face: islands at 60°N pay some of the highest delivered energy costs in the United Kingdom, and security of supply is never taken for granted. Shetland’s agriculture is overwhelmingly livestock — native Shetland sheep run on the hill and in-bye ground across the archipelago, supported by crofting townships and a smaller number of beef cattle enterprises. Margins on a Shetland croft are thin, the growing season is short, and almost every holding carries the cost of importing feed, fuel and parts across the Pentland Firth. Cutting the electricity bill on the dairy parlour, the workshop, the grain or feed store and the croft house is one of the few levers a crofter genuinely controls, and that is exactly what a well-sized roof array delivers.

The economics here run on self-consumption, not export income. The islands’ distribution network is operated by Scottish and Southern Electricity Networks (SSEN / SHEPD), and Shetland’s grid has historically been a constrained, partly islanded system, so any solar you generate is most valuable when you use it on site rather than push it back. Shetland’s irradiance profile is genuinely extreme: at this latitude June delivers close to nineteen hours of usable daylight and very strong summer generation, while December gives barely six hours and almost nothing from a fixed array. That swing is the whole design story — Shetland farm solar is sized for the long summer window and paired with substantial battery storage so the May-to-August surplus is captured, displacing imported power and the diesel generators that still back up many holdings. Against retail tariffs well above the mainland average, payback depends on how much of the output the holding uses itself — our cost guide shows the arithmetic.

Farm solar across Shetland by district

Generation across Shetland is similar everywhere — the latitude dominates over local microclimate — so system sizing tracks the enterprise and the roof more than the postcode. The table below shows representative configurations across the main districts.

Every quote should start from your half-hourly meter data and a structural survey, because on an exposed island the roof and its fixings matter as much as the panel count. For a cost benchmark, DESNZ Solar PV cost data for 2025/26 put the median installed price of a 10–50 kW system in Great Britain at £1,262 per kW, including VAT where charged and excluding batteries — see our agricultural solar panel cost guide for the full breakdown by system size.

Grants and tax relief for Shetland farms

Shetland is in Scotland, so the funding picture is different from England — and there is no FETF here. No Scottish grant pays for solar panels. The Future Farming Investment Scheme’s 2025 round listed solar panels and battery storage as not eligible; its next round is announced for winter 2026, with the item list not yet published. CARES (Local Energy Scotland) is for non-profit community groups, not farms, and the Business Energy Scotland SME Loan is not accepting new solar PV applications.

The Scottish Rural Development Programme (SRDP) and the Sustainable Agriculture Capital Grant Scheme are closed and do not fund farm solar. On the tax side, the 100% Annual Investment Allowance lets a trading farm business write off the entire cost of a qualifying solar and battery installation against taxable profits in the year of purchase — the single biggest lever in the net-cost calculation. The Smart Export Guarantee (SEG) pays for any surplus you do export, though on a constrained island grid that is a top-up rather than the basis of the business case. Our farm solar grants and funding page sets out the current status of each scheme.

Planning and grid in Shetland

For most Shetland holdings the planning route is straightforward. Roof-mounted solar on an existing agricultural building — a steading, a shed, a parlour or a feed store — is normally permitted development under Class 6J, so no full application is required: there has been no capacity limit since May 2024, provided nothing protrudes more than 1 m, though Class 6J does not apply to listed buildings, National Parks, National Scenic Areas or sites within 3 km of an aerodrome. That covers the large majority of croft and farm projects in the islands.

Ground-mounted arrays (free-standing panels are limited to 12 m² under Class 6J), or roof installations on a listed building, in a National Scenic Area or within 3 km of an aerodrome, need a planning application to Shetland Islands Council. Shetland has no National Park, but the islands carry a dense pattern of National Scenic Areas and conservation designations — including the Shetland coast NSA and numerous protected sites — and ground-mount in or near these will need careful siting and consent. On the grid side, the network is operated by Scottish and Southern Electricity Networks (SSEN / SHEPD), and any system above the smallest domestic-scale threshold needs a G99 connection application before commissioning. Because Shetland’s grid has long been constrained, it pays to submit the G99 paperwork early and size export and battery storage so a curtailed or limited connection offer does not undermine the savings — the value is in self-consumption regardless.

Typical Shetland farm solar projects

The figures below are representative ranges for the enterprise types found across Shetland, not fixed quotes — every holding is priced from its own meter data and roof survey.

• Hill sheep croft, west or north mainland — a 6-12kWp roof array on the steading paired with a battery, displacing parlour, lighting and workshop load and cutting summer generator running.

• Mixed livestock farm near Lerwick or Tingwall — a 15-30kWp array with substantial battery storage to bank the long summer surplus against high island tariffs.

• Larger beef or dairy steading, Brae or Delting — 20-40kWp across multiple roofs with a sized battery, where the continuous chilling, ventilation and pump loads soak up daytime generation directly.

• Diversified croft with agri-services or tourism — a 10-20kWp system supporting workshop, cold store or holiday-let load and improving resilience during winter supply interruptions.
