Solar panels for poultry farms: power the load you already run 24/7
Poultry farm solar panels are one of the strongest cases for solar in UK agriculture, and the reason is simple: a modern broiler or laying unit never stops drawing power. Where an arable barn sits idle for months, a poultry house runs ventilation, lighting, feed and heat around the clock — which means most of what your roof generates can be consumed on site, replacing power you would otherwise buy at full grid price. That high self-consumption is exactly what turns daytime generation into real savings.
Your poultry houses are also well suited to solar. Long, wide, shallow-pitched roofs — often the largest unbroken roofscape on the holding — give you a large, unshaded mounting area sitting directly above your single biggest energy bill. Solar panels for poultry farms convert that liability into a generating asset without taking a metre of productive land out of use. Shallow pitches trade a little yield: EU PVGIS modelling (south-facing, 14% system losses) gives about 881 kWh per kWp a year on a 10° roof at Shrewsbury against 963 at 30°.
Why poultry farms are ideal for solar
Poultry is among the most energy-intensive sectors in farming, and the shape of that demand is what makes it so well suited to solar. Unlike most agricultural loads, electricity use on a broiler or layer unit runs continuously — a true 24/7 base load rather than a few seasonal spikes.
The dominant draw is ventilation. Tunnel and minimum-vent fans manage temperature, humidity, ammonia and CO₂, and in summer they run hard for hours on end to keep birds below heat-stress thresholds. That peak fan demand lands in the middle of the day — exactly when a solar array is at full output. The alignment is almost perfect: the hotter and brighter the day, the more your fans cost to run and the more free generation you have to cover them. Ammonia matters for the panels as well as the birds: modules on or beside poultry housing should be certified to IEC 62716 for ammonia corrosion — see our guide to ammonia-resistant panels for livestock roofs.
Lighting programmes are the second continuous load. Layers follow precise photoperiod schedules to drive egg production, and broilers run staged lighting through the crop. Lights draw morning and evening, bracketing the solar window and lifting daytime self-consumption further. Add automated feed augers and chain systems, egg collection and packing lines, drinker and feed-weighing controls, and brooding heat for day-old chicks, and you have a load curve that is high, flat and predictable — the ideal partner for on-site generation.
Because that base load rarely dips below what a correctly sized array produces in daylight, poultry units export relatively little. Most of what is generated is self-consumed, displacing electricity you would otherwise buy at your full grid price. Battery storage extends the benefit into the night hours when fans and lighting still run, and an islanding-capable inverter can keep critical ventilation alive through a short grid outage — genuine resilience for a building where loss of airflow is a welfare and financial emergency.
Typical poultry farms solar system & costs
Poultry installs are sized to the load, not the roof — most sheds have far more roof than the system needs, so the array is matched to your ventilation and lighting demand for maximum self-consumption. The official benchmark is DESNZ’s Solar PV cost data for 2025/26, which puts the median for 10–50 kW systems at £1,262 per kW (including VAT where applicable, excluding batteries). It stops at 50 kW, so most poultry-scale arrays are priced from itemised quotes.
| System size | Typical site | Cost at the DESNZ 10–50 kW median |
|---|---|---|
| 50 kWp | Single small layer/broiler shed | ≈ £63,100 |
| 80 kWp | Standard broiler house | Priced from itemised quotes — no official data above 50 kW |
| 120 kWp | Large laying unit | Priced from itemised quotes — no official data above 50 kW |
| 200 kWp | Multi-house broiler site | Priced from itemised quotes — no official data above 50 kW |
| 300 kWp | Integrated poultry enterprise | Priced from itemised quotes — no official data above 50 kW |
Payback depends on what the system costs, how much of its output the unit uses itself in daylight, and your grid price, so a bigger array only pays if the base load absorbs the extra generation. Ask for a calculation from your own half-hourly meter data; see our agricultural solar panel cost breakdown and worked payback example.
Equipment & energy breakdown
Understanding where the kilowatts go is the key to sizing a poultry array correctly. On a typical unit the load splits roughly like this:
- Ventilation fans — the largest single draw. Minimum-vent fans run continuously; tunnel fans cut in through warm weather and can dominate the summer bill. Because peak fan demand coincides with peak solar output, panels offset this load more efficiently than any other.
- Lighting programmes. LED photoperiod lighting for layers and staged broiler lighting run morning and evening, with a strong daytime overlap that solar covers directly. Even after an LED retrofit, the cumulative 24/7 run-time keeps lighting a meaningful share of consumption.
- Heating and brooding. Day-old chicks need high brooding temperatures; gas or electric heat carries the early days of each crop. Electric brooding and circulation fans draw from the array, while solar offsets the parasitic power even where primary heat is gas.
- Feed and egg handling. Augers, chain feeders, feed weighers, egg-collection belts and packing-line motors cycle throughout the day — modest individually, material in aggregate, and almost entirely daytime loads.
- Controls, drinkers and refrigeration. Climate controllers, water systems and any on-site egg chilling add a steady background draw that solar trims continuously.
Because this profile is dominated by daytime and continuous loads, a correctly sized poultry array self-consumes most of what it generates — the metric that matters most for returns. Where summer ventilation runs into the evening, battery storage captures midday surplus and discharges it after dark, lifting self-consumption further still.
Grants and finance for poultry farms
Grant support for poultry farm solar is thinner than it was. In England, the Improving Farm Productivity (IFP) grant funded 25% of eligible costs, with grants of £15,000 to £100,000, for rooftop solar and irrigation-reservoir solar only — ground-mounted arrays on land were not eligible. Round 2 has closed, and no solar round is open at the time of writing (September 2026). The Farming Equipment and Technology Fund’s 2026 window closed on 12 May 2026. Wales, Scotland and Northern Ireland run their own schemes.
Tax relief is now the main support. Solar panels are special rate expenditure under section 104A(1)(g) of the Capital Allowances Act 2001, and the £1m Annual Investment Allowance (AIA) lets most farm businesses deduct the full cost in the year of purchase. Companies can instead claim the 50% first-year allowance on new and unused special-rate assets bought from 1 April 2023, with the rest in the special rate pool at 6% a year. Full expensing does not apply to solar panels. Any electricity you do export is paid for under the Smart Export Guarantee (SEG), adding a modest top-up on the days your birds are between crops and the base load drops.
For zero-upfront delivery, a Power Purchase Agreement lets you pay only for the solar electricity you use at a rate set below your grid tariff — no capital, no maintenance liability. Asset finance over a fixed term suits units with steady cash flow that want to own the system outright.

Common questions
How much do solar panels cost for a poultry farm?
DESNZ figures for 2025/26 put the median installed cost of a 10–50 kW system at £1,262 per kW, or about £63,100 for 50 kW. Most broiler and layer sheds take bigger arrays than that, and there is no official cost series above 50 kW, so they are priced from itemised quotes.
What size solar system does a poultry farm need?
Large broiler and laying sheds usually take 80–150 kWp on a single roof, while multi-house sites scale to 200–300 kWp. Sizing is driven by your ventilation and lighting load rather than roof area alone — most poultry units have far more roof than they need, so the system is matched to your half-hourly demand for maximum self-consumption.
What drives solar payback on a poultry farm?
Poultry units run a continuous 24/7 base load — fans, lighting programmes, feed augers and brooding heat never fully switch off — so most generated power is used on site rather than exported at a lower rate. Payback depends on what the system costs, how much of its output the unit uses itself in daylight and your grid price, so ask for a calculation built from your own half-hourly meter data.
Will solar power keep my ventilation running during an outage?
On its own, a grid-tied solar array shuts down in a power cut for safety. Paired with battery storage and an islanding inverter, it can keep critical ventilation and life-support fans running through short outages — vital protection for a shed full of birds, where minutes without airflow risk heat stress and losses.
Does installing solar disrupt biosecurity on a working poultry unit?
No. Roof-mounted installs are scheduled around your flock cycle and crew-change windows, with installers following your site biosecurity protocol — dedicated footwear, disinfection points and controlled access. Most poultry house arrays are fitted between flocks or via external scaffold access, so birds and litter management are never compromised.
