Scott Closures & Plastics is a Poole-based manufacturer of closures and plastic components. To reduce operating costs and strengthen its environmental credentials, the company partnered with DES Renewable Energy to install a large-scale rooftop solar PV system that generates clean electricity onsite, lowers energy bills and supports its long-term sustainability goals.
Project overview
Scott Closures & Plastics commissioned DES Renewable Energy to install a 436.65 kWp solar PV system across its pitched industrial roof. The installation comprises 710 x 615W Astronergy (CHINT Solar) panels connected to a SolaX inverter array delivering 350kW of inverter power. The project set out to reduce electricity costs, lower carbon emissions and enhance the company’s long-term financial sustainability.
Project details
- Company: Scott Closures & Plastics
- Location: 57 Balena Close, Poole, BH17 7DY
- Solar system capacity: 436.65 kWp
- Estimated annual generation: 357,976 kWh
- Installation type: Pitched industrial roof solar panels
- Project timeline: Full project delivered over standard installation phases 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 the 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 710 x 615W Astronergy (CHINT Solar) panels across the pitched industrial roof. Power conversion is handled by a SolaX inverter array — 2 x X3-FTH-125K-G2 (125kW each) and 1 x X3-FTH-100K (100kW) — providing 350kW of total inverter capacity for efficient energy management and integration with the site’s electrical infrastructure. DES Renewable Energy also ensured compliance with building regulations, electrical standards and industry best practices, obtaining all necessary permits and approvals for a fully compliant and 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 inverters 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 357,976 kWh of clean energy each year, saving an estimated 74 tonnes of CO2 annually and supporting sustainability goals
- Financial returns: savings on energy costs contribute to long-term financial sustainability
- Public image: demonstrates responsible energy practices to visitors, stakeholders and the wider community
