FP McCann Ltd is a precast concrete products manufacturer based at Brascote Lane, Cadeby, Nuneaton. To reduce operating costs and strengthen its environmental credentials, the company partnered with DES Renewable Energy to install a rooftop solar PV system that generates clean electricity onsite, lowers energy bills and supports its long-term sustainability goals.
Project overview
FP McCann commissioned DES Renewable Energy to install a 59.6 kWp solar PV system across its pitched metal profile roof. The installation comprised 137 x 435 W Canadian Solar panels connected to a Solis S5-GC50K 50 kW string inverter. The project aimed to reduce electricity costs, lower carbon emissions and enhance long-term financial sustainability.
Project details
- Company: FP McCann Ltd
- Location: Brascote Lane, Cadeby, Nuneaton, CV13 0BB
- Solar system capacity: 59.6 kWp
- Estimated annual generation: 45,951 kWh
- Installation type: Pitched metal profile roof solar panels
- Project timeline: Delivered in 2024, from survey to commissioning
The objectives
- Reduce electricity costs and dependence on grid energy
- Improve environmental sustainability by reducing the site’s carbon footprint
- Achieve long-term operational savings and financial returns
- Demonstrate responsible energy practices to customers, staff and stakeholders
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 137 x 435 W Canadian Solar panels across the pitched metal profile roof, with power conversion handled by a Solis S5-GC50K 50 kW string inverter. The system integrates with the site’s existing electrical infrastructure for efficient energy management.
DES Renewable Energy ensured compliance with building regulations, electrical standards and industry best practices, obtaining all necessary permits and approvals for a fully compliant, safe installation.
Installation and completion
The installation was carried out with minimal disruption to day-to-day site operations. Panels were securely mounted, connected to the inverter and integrated with the existing electrical system. Comprehensive testing and commissioning verified the system’s performance, functionality and safety. From initial assessment to completed commissioning, DES Renewable Energy provided 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 45,951 kWh of clean energy each year, saving an estimated 9.5 tonnes of CO2 annually
- Financial returns: savings on energy costs contribute to long-term financial sustainability
- Public image: demonstrates responsible energy practices to customers, staff and stakeholders
