Agrivoltaics – combining solar energy production with agriculture on the same land – sounds like the perfect solution to a growing tension. Solar farms need land. Farms need income. Food security matters. Climate change demands renewable energy. What if we could do both at once?
The concept isn’t new, but it’s gaining serious momentum worldwide. In the UK, where agricultural land is increasingly being converted to solar farms (often controversially), agrivoltaics offers a middle path: generating clean electricity while continuing to grow food or raise livestock.
But does it actually work in the UK’s climate? Can crops really thrive under solar panels? Is it economically viable for British farmers? This guide examines the evidence, explores the different approaches, and assesses whether agrivoltaics has a genuine future in UK agriculture.
Agrivoltaics at a Glance
| What it is | Dual use of land for solar energy and agriculture simultaneously |
| Also called | Agri-PV, solar sharing, dual-use solar |
| Main approaches | Elevated panels, vertical bifacial, ground-mounted with grazing |
| UK suitability | Good for grazing; promising for some crops; ongoing research |
| Benefits | Dual income; land efficiency; crop protection; biodiversity |
| Challenges | Higher costs; crop selection; planning; practical complexity |
What Is Agrivoltaics?
The Basic Concept
Agrivoltaics involves installing solar panels on agricultural land in ways that allow farming to continue underneath or alongside them:
| Traditional Solar Farm | Agrivoltaic System |
|---|---|
| Land used exclusively for solar | Land used for both solar and farming |
| Agricultural use ceases | Agricultural production continues |
| Panels close to ground | Panels elevated or spaced for access |
| Maximum panel density | Optimised for dual use |
| Single income stream | Dual income streams |
For the wider context on solar on UK farmland – including ground-mounted economics, planning, and what farmers should consider before signing a lease – see our solar panels for farms guide.

Types of Agrivoltaic Systems
1. Elevated/Stilted Systems
| Description | Panels raised 2-5+ metres on posts, allowing farming underneath |
| Clearance | Typically 2.5-4m to allow machinery access |
| Best for | Arable crops; vegetables; orchards |
| Pros | Full machinery access; crops get rain and light |
| Cons | Higher cost; more complex structure |
2. Vertical Bifacial Systems
| Description | Panels mounted vertically in rows; bifacial captures light both sides |
| Orientation | Usually east-west facing |
| Row spacing | Wide enough for farming between rows |
| Best for | Grassland; grazing; arable between rows |
| Pros | Morning/evening generation peaks; snow shedding; good for grazing |
| Cons | Lower total generation than optimal tilt; wind exposure |
3. Ground-Mounted with Grazing
| Description | Standard or slightly elevated ground-mounted panels with livestock grazing |
| Panel height | 0.8-2m clearance for sheep; lower for some systems |
| Best for | Sheep grazing; sometimes cattle (with higher panels) |
| Pros | Lower cost; proven approach; natural vegetation management |
| Cons | Limited to grazing; not arable crops |
4. Inter-Row Cropping
| Description | Standard rows with wider spacing; crops grown between |
| Row spacing | 5-15+ metres between panel rows |
| Best for | Shade-tolerant crops; strips of arable |
| Pros | Moderate cost; allows varied cropping |
| Cons | Lower panel density; crops may be uneven |
5. Orchard/Vineyard Integration
| Description | Panels above or between fruit trees/vines |
| Best for | Apples, soft fruit, grapes, berries |
| Pros | Shade protection; hail protection; existing row structure |
| Cons | Complex installation; access for harvest |
6. Greenhouse/Polytunnel Integration
| Description | Semi-transparent or partial panels on greenhouse roofs |
| Best for | Protected cropping; controlled environment |
| Pros | Reduces overheating; dual use of structure |
| Cons | Reduced light for crops; specialised panels needed |
How Crops Perform Under Panels
The Shade Question
The key concern: don’t crops need full sun? The answer is nuanced:
| Factor | Reality |
|---|---|
| Light saturation | Many crops reach maximum photosynthesis below full sun |
| Shade tolerance | Varies hugely between crops |
| Heat stress | Shade can protect crops in hot weather |
| Water retention | Shade reduces evaporation; less irrigation needed |
| UK climate | Less intense sun than southern regions; shade impact less severe |
Crop Performance Research
Studies show varied results by crop type:
| Crop | Yield Under Panels | Notes |
|---|---|---|
| Lettuce | Same or higher | Benefits from shade; less bolting |
| Spinach | Same or higher | Shade-tolerant; quality improved |
| Kale | Similar | Tolerates partial shade well |
| Potatoes | 80-100% | Moderate shade tolerance |
| Wheat | 70-90% | Some yield reduction typical |
| Grass (grazing) | 80-100% | Often maintains yield; stays greener |
| Soft fruit | 80-100% | Shade can benefit; reduces sunscald |
| Apples | 85-95% | Hail/frost protection benefits |
| Grapes | 90-100% | Shade benefits in hot climates |
| Maize | 70-85% | Sun-loving; more affected |
UK-Relevant Crops
Crops with good potential for UK agrivoltaics:
| Crop Category | Examples | Potential |
|---|---|---|
| Leafy vegetables | Lettuce, spinach, chard, kale | Excellent – often benefit from shade |
| Brassicas | Cabbage, broccoli, cauliflower | Good – moderate shade tolerance |
| Root vegetables | Potatoes, carrots, beetroot | Good – reasonable tolerance |
| Soft fruit | Strawberries, raspberries, blackcurrants | Very good – shade protection valuable |
| Orchard fruit | Apples, pears, plums | Good – hail/frost protection |
| Grass/grazing | Sheep pasture, hay | Excellent – most proven approach |
| Herbs | Mint, parsley, coriander | Good – many tolerate shade |
Livestock and Solar
Sheep Grazing (Most Common)
Sheep grazing under solar panels is the most established form of UK agrivoltaics:
| Why sheep? | Right size; don’t damage panels; manage vegetation |
| Panel height needed | 0.8-1.2m minimum clearance |
| Stocking density | Often similar to open pasture |
| Benefits for sheep | Shade in summer; shelter from weather; continue grazing |
| Benefits for solar | Vegetation management without mowing; no chemicals |
| UK examples | Many solar farms already use sheep grazing |
Cattle
| Feasibility | Possible but more challenging |
| Panel height needed | 2m+ clearance; robust mounting |
| Concerns | Rubbing on structures; weight; reach |
| Solutions | Reinforced posts; protective barriers; higher panels |
| Status | Limited but growing interest |
Poultry
| Free-range chickens | Panels provide shade; chickens naturally seek cover |
| Benefits | Improved welfare; panels as shelter; pest control |
| Considerations | Fencing; predator protection; panel soiling |
| Status | Growing interest; some commercial trials |
Bees and Pollinators
| Approach | Wildflower planting under/around panels; beehives on site |
| Benefits | Pollinator habitat; honey production; biodiversity |
| UK relevance | Strong fit with Biodiversity Net Gain requirements |
| Status | Increasingly common on UK solar farms |
For more on how solar farms can be deliberately designed as pollinator habitat – including planting mixes, mowing regimes and how this stacks against Biodiversity Net Gain – see our pollinator-friendly solar farms guide.

UK Agrivoltaics: Current State
Existing Activity
| Type | Status in UK |
|---|---|
| Sheep grazing on solar farms | Widespread; many existing sites |
| Elevated crop systems | Research stage; pilot projects |
| Vertical bifacial | Limited; some trials |
| Orchard integration | Research stage; growing interest |
| Greenhouse integration | Some commercial examples |
UK Research and Trials
Key UK agrivoltaics research:
| Institution / Project | Focus |
|---|---|
| University of Sheffield | Crop performance; optimal designs; UK siting |
| University of Reading | Agricultural impacts; economics |
| Lancaster University (Energy Lancaster) | Demonstrators; integrated food and power systems |
| NIAB | Arable crop trials under panels |
| Solar Energy UK | Industry guidance; best practice |
| Various solar developers | Commercial pilot projects |
A 2025 University of Sheffield study found that well-sited UK agrivoltaics could meet UK electricity demand more than four times over without losing farmland, with East and South-East England (Cambridgeshire, Essex, Lincolnshire) emerging as the most suitable regions on the basis of flat land, grid connectivity and solar irradiance. The complementary research programme at Lancaster University’s Energy Lancaster is building demonstrator sites to address the UK’s main gap: practical, long-term performance data under domestic climate conditions.
Policy Environment
| Aspect | Current Status |
|---|---|
| Government support | Growing; mentioned in energy strategy; funding available |
| Planning policy | Dual-use can support planning applications |
| Agricultural policy | ELMS may provide support; land classification questions |
| Industry bodies | NFU cautiously supportive; Solar Energy UK promoting |
The UK government’s Solar Roadmap (2025) sets a target of 45-47 GW of solar by 2030 and explicitly emphasises driving solar across multifunctional uses of space – including rooftops, car parks, water bodies (see floating solar farms) and brownfield land (see solar panels on brownfield sites) – while maintaining planning protections for the best agricultural land. Agrivoltaics fits naturally into that direction of travel.
Does Agrivoltaics Work in the UK Climate?
UK-Specific Factors
| Factor | Impact on Agrivoltaics |
|---|---|
| Lower solar intensity | Crops less affected by shade than in sunny climates |
| Ample rainfall | Less need for shade to reduce evaporation |
| Mild temperatures | Less benefit from cooling effect |
| Variable weather | Shelter benefits in storms |
| Shorter growing season | May limit benefits from extended season |
| Grazing tradition | Strong fit for sheep systems |
Advantages in UK
| Advantage | Why It Matters Here |
|---|---|
| Grazing excellent fit | Sheep farming well-established; panels provide shelter |
| Shade-tolerant crops | Many UK crops (leafy veg, brassicas) tolerate partial shade |
| Climate change adaptation | As UK summers warm, shade becomes more beneficial |
| Land pressure | High demand for land makes dual use attractive |
| Planning support | Continued agriculture can ease planning concerns |
Challenges in UK
| Challenge | Detail |
|---|---|
| Less dramatic benefits | Shade/cooling benefits smaller than hot climates |
| Higher structure costs | Elevated systems expensive relative to returns |
| Limited research | Less UK-specific data than some countries |
| Weather and wind | Elevated structures need robust engineering |
| Farming culture | Some resistance to “solar taking over farms” |
UK Climate Verdict
Agrivoltaics can work in the UK, but the strongest case is for:
| Best UK Use Case | Why It Works |
|---|---|
| Sheep grazing | Already proven; widespread; clear benefits |
| Soft fruit and orchards | Good potential; shade and hail protection valuable |
| Shade-tolerant vegetables | Lettuce, spinach, leafy crops promising |
| Biodiversity integration | Wildflowers, pollinators, habitat creation |
Less strong case for full-scale arable crops under elevated panels (economics challenging) and heat-stress mitigation (less needed than Mediterranean climates).
Economics of UK Agrivoltaics
Cost Considerations
| System Type | Cost vs Standard Solar | Reason |
|---|---|---|
| Ground-mount + grazing | Similar or slightly lower | Reduced vegetation management |
| Elevated panels (2-3m) | +30-50% | Stronger structures; more material |
| High elevation (4m+) | +50-100% | Significant structural costs |
| Vertical bifacial | +10-30% | Bifacial panels; different mounting |
Revenue Streams
| Income Source | Contribution |
|---|---|
| Solar electricity | Primary income; may be slightly reduced if panel density lower |
| Agricultural produce | Continued crop/livestock income; may be 70-100% of previous |
| Grazing rent | If farmer grazes others’ animals |
| Subsidies | Agricultural payments may continue if farming continues |
| Biodiversity payments | ELMS payments for habitat creation |
Economic Example: Sheep Grazing
| Solar farm size | 50 acres |
| Solar income | ~£50,000-£70,000/year (lease) or more if farmer-owned |
| Sheep grazing income | ~£3,000-£8,000/year (vs £0 if no grazing) |
| Vegetation management saved | ~£2,000-£5,000/year |
| Total benefit of grazing | £5,000-£13,000/year additional value |
Economic Example: Elevated Crop System
| Additional structure cost | +£200,000-£400,000 per MW |
| Solar output | May be 80-90% of standard (lower density) |
| Crop value | Depends hugely on crop; £500-£5,000/acre |
| Payback | Often challenging unless high-value crops |
| Best suited for | High-value soft fruit; vegetables; organic premium |
For farmer-owned models that may help bridge the elevated-system economics, see our guide to solar cooperatives – communal ownership structures can reduce per-farmer capital exposure on more complex agrivoltaic builds.

Agrivoltaics offers a compelling answer to the solar-versus-food debate: why not both? In the UK, the simplest form – sheep grazing under solar panels – is already widespread and proven. More ambitious approaches involving crops under elevated panels are at an earlier stage, with economics that work best for high-value produce.
The UK’s climate means agrivoltaics won’t deliver the same dramatic benefits seen in hot countries where shade prevents crop failure. But the benefits are real: dual income for farmers, continued food production, easier planning approvals, and biodiversity enhancement. As land pressure increases and the technology matures, agrivoltaics will likely become a standard consideration for new solar developments.
For farmers considering solar on their land, agrivoltaics offers a middle path: participate in the renewable energy transition while continuing to farm. It’s not the right solution for every situation, but for many, it’s exactly the right balance between energy, food, and income.
Considering solar on your farm? Start with the simplest, lowest-risk option that fits your land: sheep grazing under standard ground-mounted panels is proven, well-financed and easier to permit than elevated crop systems. Reserve elevated agrivoltaics for genuine high-value cases – soft fruit, orchards, vineyards, or sites where pure solar would be refused planning permission.
Get at least three quotes that include agricultural management plans, talk to a specialist land agent who has dealt with solar leases, and check whether your council and Local Plan currently treat agrivoltaic dual use as a material planning consideration. The economics improve substantially when planning support and continued ELMS payments are factored in alongside the energy income.
