IUF Investments is a commercial property investment at Lombard Road in London. To reduce its operating costs and strengthen its environmental credentials, it 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
IUF Investments commissioned DES Renewable Energy to deliver a 58.08 kWp rooftop solar PV system. The installation comprised 88 x 660W Aiko panels connected to a Solax X3-MGA-50kW inverter, designed to reduce electricity costs, lower carbon emissions and enhance long-term financial sustainability.
Project details
- Company: IUF Investments
- Location: 9 Lombard Road, London, SW19 3UP
- Solar system capacity: 58.08 kWp
- Estimated annual generation: 55,176 kWh
- Installation type: Rooftop solar panels
- Project timeline: Delivered 2026, from survey to commissioning
The objectives
- Reduce electricity costs and dependence on grid energy
- Improve environmental sustainability by reducing the carbon footprint
- Achieve long-term operational savings and financial returns
- Demonstrate responsible energy practices to tenants, 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 88 x 660W Aiko panels, with power conversion handled by a Solax X3-MGA-50kW 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
Delivered in 2026 from survey to commissioning, 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, 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 55,176 kWh of clean energy each year, saving an estimated 11.4 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 tenants, staff and stakeholders
