Greenmount Projects Ltd is a business based in Newton-le-Willows, Merseyside. To reduce operating costs and strengthen its environmental credentials, the company partnered with DES Renewable Energy to install a rooftop solar PV system with battery storage and EV charging that generates clean electricity onsite, lowers energy bills and supports its long-term sustainability goals.
Project overview
Greenmount Projects Ltd commissioned DES Renewable Energy to install a 31.62 kWp solar PV system across its slate roof. The installation comprised 51 x 620 Wp ASTROnergy panels connected to a SolaX X3-Ultra 30 kW inverter, paired with SolaX HS25 battery storage and an EV charger. The project aimed to reduce electricity costs, lower carbon emissions and enhance long-term financial sustainability.
Project details
- Company: Greenmount Projects Ltd
- Location: Hamer House, 4 The Parks, Newton-le-Willows, WA12 0JQ
- Solar system capacity: 31.62 kWp
- Estimated annual generation: 27,219 kWh
- Installation type: Pitched (slate) roof solar panels with battery storage and EV charging
- Project timeline: Delivered 2025, from survey to commissioning
The objectives
- Reduce electricity costs and dependence on grid energy
- Improve environmental sustainability by reducing the company’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 51 x 620 Wp ASTROnergy panels across the slate roof. Power conversion is handled by a SolaX X3-Ultra 30 kW inverter, paired with SolaX HS25 battery storage to maximise self-consumption, plus an EV charger. 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 27,219 kWh of clean energy each year, saving an estimated 5.6 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
