Here's how other agricultural operations have reduced their energy costs.

Dairy Farm, Yorkshire
New SolarChallenge
200 cow robotic dairy with high refrigeration and hot water loads. Bills averaging £4,200/month.
Solution
100kW solar, 128kWh battery storage with 72kW max output (100A 3-phase supply)
Result
Reduced monthly bills by £2,100 (52%)
"The system paid for itself faster than we expected. We're now looking at expanding."

Broiler Farm, Lincolnshire
Existing SolarChallenge
High-density broiler sheds running 24/7 ventilation, heating and lighting. Existing 150 kW solar array exporting most generation at low rates.
Solution
288kWh WattBox with 108kW max output (150A 3-phase supply) integrated with existing solar system
Result
Captured extra £12k/year of previously exported solar. Supplied relible power during outages.
"Our export rate dropped to almost zero so it made sense to store as much solar as possible plus get all the other benefits."

Potato Store, Lincolnshire
Existing SolarChallenge
Refrigeration and ventilation running long hours post-harvest. High peak electricty rate (44p) existing 120 kW solar exported at 3p but had to buy energy back at 44p.
Solution
Connection of existing solar, 128kWh battery storage with 72kW max output (100A 3-phase supply). Night time charging at 33p to maximise savings.
Result
Reduced monthly bills by extra 20% on top of existing solar savings.
"We utilise more of our own solar to get a better return on investment whilst also avoiding the high peak rates as much as possible."
