Cowling Agriculture, a smallholder and agri specialist, aimed to boost its sustainability initiatives while cutting operational expenses.
Project Scope:
Installation of a 51.67kW solar photovoltaic (PV) system, over 2 roof spaces, with a 10kW battery.
Solution Implemented:
Sunlit Solar designed and installed a custom solar PV array that maximised the roof space. This has saved the farm significantly on their electrical running costs.
Results Achieved:
Clean Energy Generation:
The installed solar PV system is projected to produce an estimated 51.61MWh of clean energy annually (across the 2 roof spaces).
Carbon Emissions Reduction:
Cowling Agriculture expects to cut carbon emissions by 9.98 tons annually, in line with their commitment to environmental sustainability.
Operational Efficiency:
By utilising solar energy, and installing a 10kW battery, the company is set to reduce its dependence on traditional energy sources, resulting in long-term cost savings and improved operational efficiency.
