Solar Panels for Pig Buildings

Pig buildings are among the most energy-intensive structures in UK agriculture. The combination of continuous ventilation, precise climate control, and automated feeding creates electricity bills that solar panels can dramatically reduce, with typical payback periods of 3-5 years.

Why Pig Buildings Are Excellent for Solar

The intensive energy demands of modern pig production create one of the strongest financial cases for solar in agriculture.

Pig Building Energy by Production Stage

Energy demands vary significantly across pig production stages. Solar system design must account for these variations throughout the production cycle.

Highlights

• Farrowing House
• 28-32C
• 40,000-70,000 kWh/yr
• Highest heating demand. Creep heating for piglets via heat lamps or heated pads. Precise temperature control critical for piglet survival rates.
• Weaner Accommodation
• 26-28C
• 25,000-45,000 kWh/yr
• Transition heating and intensive ventilation. Post-weaning environment management significantly affects growth rates and mortality.
• Grower-Finisher Houses
• 18-22C
• 30,000-55,000 kWh/yr
• Lower heating but higher ventilation demand as pigs generate more metabolic heat. Largest buildings with biggest roof areas for solar.
• Feed Mill & Storage
• Ambient
• 20,000-40,000 kWh/yr
• Grinding, mixing, and conveying systems. Intermittent high-power demand during milling aligns well with midday solar peaks.

• 100kW (single finisher house)
• £80,000-£105,000
• £25,000-£32,000/yr
• 200kW (farrowing + finishers)
• £155,000-£200,000
• £50,000-£62,000/yr
• 400kW (full farrow-to-finish)
• £300,000-£380,000
• £95,000-£120,000/yr
