Grange Farm, Banbury is a working farm on Wykham Lane in Banbury, Oxfordshire. Like many energy-hungry agricultural operations, the farm saw an opportunity in its barn-roof space to cut running costs and strengthen its environmental credentials, so it partnered with DES Renewable Energy to install a solar PV system that generates clean electricity onsite, lowers energy bills and supports its long-term sustainability goals.
Project overview
Grange Farm, Banbury commissioned DES Renewable Energy to deliver a 31 kWp rooftop solar PV system. The installation comprises 50 x 620W Astronergy panels connected to a 20kW three-phase Solax inverter, designed to reduce electricity costs, lower carbon emissions and enhance the farm’s long-term financial sustainability.
Project details
- Company: Grange Farm, Banbury
- Location: Grange Farm, Wykham Lane, Banbury, OX15 5DS
- Solar system capacity: 31 kWp
- Estimated annual generation: 29,450 kWh
- Installation type: Rooftop solar panels
- Project timeline: Designed and specified by DES Renewable Energy
The objectives
- Reduce electricity costs and dependence on grid energy
- Improve environmental sustainability by reducing the farm’s carbon footprint
- Achieve long-term operational savings and financial returns
- Demonstrate responsible energy practices to the farm, its staff and the local community
The solution: bespoke assessment and design
DES Renewable Energy conducted a comprehensive assessment of roof space, structural considerations, sun exposure and interlocking constraints. This ensured optimal placement and system sizing to maximise energy production and long-term reliability.
The system was designed with 50 x 620W Astronergy panels, with power conversion handled by a 20kW three-phase Solax inverter. The design integrates with the site’s existing electrical infrastructure for efficient energy management, and DES Renewable Energy ensured compliance with building regulations, electrical standards and industry best practices, with all necessary permits and approvals obtained for a fully compliant, safe installation.
Installation and completion
The installation is carried out with minimal disruption to day-to-day site operations. Panels are securely mounted, connected to the inverter and integrated with the existing electrical system, with comprehensive testing and commissioning verifying the system’s performance, functionality and safety. From initial assessment to completed commissioning, DES Renewable Energy provides a turnkey solution that ensures optimal energy generation, regulatory compliance and sustainable operational savings.
The results
- Energy cost reduction: lower electricity bills and reduced reliance on grid energy
- Environmental impact: an estimated 29,450 kWh of clean energy each year, saving an estimated 6.1 tonnes of CO2 annually and supporting the farm’s sustainability goals
- Financial returns: savings on energy costs contribute to long-term financial sustainability
- Public image: demonstrates responsible energy practices to the farm, its staff and the local community
