Solar Panels for Poultry Houses
High-efficiency solar installations for broiler houses, laying units, and free-range poultry buildings. Poultry housing is one of the most energy-intensive farm building types — and one of the most rewarding for solar investment.
Why Poultry Houses Have the Best Solar ROI in Agriculture
Poultry houses are the most energy-intensive building type in UK agriculture. A standard 40,000-bird broiler house consumes between 250,000 and 350,000 kWh per year — comparable to more than 80 average UK homes. That extraordinary consumption is driven by systems that cannot be switched off: ventilation fans that run continuously to maintain air quality, lighting programmes of 18 to 22 hours per day throughout every crop cycle, heating systems that are critical to bird survival in the first two weeks after placement, and automated feed, water, and control room equipment running around the clock.
This relentless, predictable demand is precisely what makes poultry housing so well-suited to solar generation. Because there is always a significant load present on the building regardless of the time of day, self-consumption rates of 85% or higher are common on poultry units — meaning the vast majority of electricity generated by the panels is used directly on site rather than exported to the grid at a lower rate. The financial consequence of this is transformational: poultry house solar systems typically achieve a payback period of 3 to 5 years, the fastest of any farm building type in UK agriculture.
On a 25-year panel lifespan, the cumulative savings from a well-designed poultry solar installation can exceed the original cost of the building itself. For contract broiler producers operating on fixed margins, and for free-range and organic producers facing rising energy costs, solar is one of the most significant financial decisions available.

Energy Profile of a Poultry Unit
Understanding where electricity is consumed in a poultry house is the foundation of an effective solar design. Each end use has a distinct operating pattern that affects how much solar generation can be absorbed on site. The breakdown below is representative of a modern, fully-enclosed broiler house operating at standard stocking densities.
The single largest consumer. Tunnel and cross ventilation fans run continuously, with variable speed drives modulating output to maintain target temperature and CO2 levels. Energy use peaks in warm weather and during the heavier-weight final weeks of each crop.
LED lighting on programmable controllers operates for up to 22 hours per day for the majority of the crop cycle. Even with modern LED fixtures, the sheer scale of a broiler house — often over 100 metres long — means lighting is a major ongoing cost that solar can substantially offset.
Electric or gas-fired radiant heaters and hot water systems maintain house temperature at 33-34°C during placement week, stepping down by approximately 0.5°C per day. For houses with electric heating, solar can contribute directly to brooding energy costs during spring and summer crops.
Chain or pan feeding systems, nipple drinker pressure systems, weighing platforms, alarm systems, and environmental monitoring all contribute a consistent background load. Control room computers and power conditioning equipment for sensitive electronics add to this category.
Why 24/7 Demand Changes the Economics
Most commercial buildings have an energy demand that falls to near zero at night. Poultry houses do not. Fans run continuously, lights are on for up to 22 hours, and monitoring systems never sleep. This means your solar array is generating into a building that is almost always consuming — eliminating the export losses that reduce returns on less intensive agricultural installations. The result is an investment case that stands up even in less than ideal roof orientations or partially shaded situations.
System Sizing Guide for Poultry Houses
Solar system capacity is matched to the total electricity consumption of your poultry unit. Larger installations on multi-house sites benefit from shared infrastructure costs, improving the economics further.

Biosecurity and Installation Considerations
Poultry house solar installation requires a different approach to any other agricultural building type. Our team understands the biosecurity environment of contract poultry production and works within it.
Installing Between Crops: Why Timing Is Everything
The single most important differentiator for poultry house solar installation is biosecurity. Unlike a grain store or machinery shed where work can proceed at any time, access to a broiler or laying house is strictly controlled throughout the crop cycle. No external contractors enter a stocked poultry house under any circumstances — and rightly so. This means the entire installation must be completed within the depopulation and clean-out window between crops.
For most contract broiler producers, this window is between 4 and 6 days in length. Our poultry installation teams are experienced at working within this constraint and plan every project in advance to ensure the full system — panels, racking, cabling, inverter, metering, and DNO notification — is completed and commissioned before the next placement. We coordinate directly with your contract company's service team where required to confirm the schedule and avoid any conflict with cleaning and disinfection programmes.
For multi-house sites, we typically stagger installations across successive clean-out periods to reduce on-site workforce numbers and eliminate any risk of cross-contamination between houses at different stages of the crop cycle.
Cabling, Penetrations and Pest Exclusion
Poultry houses are designed and maintained as pest-exclusion environments. Any penetration of the building envelope creates a potential entry point for rodents and wild birds, which is unacceptable both for biosecurity and for assurance scheme compliance. Our installation methodology addresses this with purpose-designed sealed cable entry points that meet the requirements of RSPCA Assured, Red Tractor, and Lion Code schemes.
All DC cabling from roof-mounted panels is routed through weatherproof conduit and enters the building through a single sealed penetration point fitted with expanding foam and metal rodent exclusion collars. Inverters, monitoring equipment, and any electrical switchgear associated with the solar system are located in a separate weatherproof cabinet outside the house envelope — never inside the bird area.
Our Biosecurity Commitments
- Installation during depopulation/clean-out only — no access to stocked houses
- Sealed cable penetrations meeting assurance scheme requirements
- External inverter and switchgear cabinet — no equipment inside bird area
- Vehicle disinfection and dedicated footwear protocols on all visits
- Coordination with your contract company's technical team as required
Poultry Solar Case Study
A real-world example from a contract broiler producer in Shropshire illustrates the financial performance achievable on a two-house site.
Location
Shropshire, West Midlands
System Type
Roof-mounted, grid-tied
Installation Date
2023, between crops 4 and 5
Two-house contract broiler unit with a combined stocking capacity of 80,000 birds across two 120-metre houses. The producer was spending over £58,000 per year on electricity and sought to reduce fixed overhead costs to protect contract renewal viability.
Project Details
Both houses were installed during consecutive clean-out periods four weeks apart, using a dedicated poultry installation crew familiar with the biosecurity requirements of the contract company. DC cabling was routed externally along the ridge and brought into a shared inverter cabinet situated between the two houses, minimising cable runs and avoiding any penetration of the house side walls.
The roof orientation on both houses was within 15 degrees of due south, making Shropshire an ideal generation location. System monitoring showed a self-consumption rate of 88% in the first full year of operation, with minimal export occurring only during the short clean-out periods between crops.
Financial Summary
- Annual electricity saving £32,000
- Annual SEG export income £1,800
- Total annual benefit £33,800
- Simple payback period 4.1 years
- Projected 25-year net benefit £803,000
25-year figure assumes 3.5% annual electricity price inflation. Actual results may vary.
