Nanaksar Gurdwara is a Sikh temple (gurdwara) in Southall, West London. To reduce its running costs and strengthen its environmental credentials, the gurdwara partnered with DES Renewable Energy to install a rooftop solar PV system with battery storage — generating clean electricity on site, lowering energy bills, and supporting its long-term sustainability goals.
Project overview
Nanaksar Gurdwara commissioned DES Renewable Energy to install a 25 kWp solar PV system across its roof. The installation comprised 50 x 500 W DMEGC panels connected to a 20 kW three-phase Sigenergy inverter with approximately 22 kWh of Sigenergy battery storage. The project aimed to reduce electricity costs, lower carbon emissions, and enhance long-term financial sustainability.
Project details
- Company: Nanaksar Gurdwara
- Location: 60 Kingsbridge Crescent, Southall, UB1 2DL
- Solar system capacity: 25 kWp
- Estimated annual generation: 23,750 kWh
- Installation type: Rooftop solar panels with battery storage
- 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 carbon footprint
- Achieve long-term operational savings and financial returns
- Demonstrate responsible energy practices to the congregation, 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 to ensure optimal placement and system sizing. The system was designed with 50 x 500 W DMEGC panels, with power conversion handled by a 20 kW three-phase Sigenergy inverter paired with approximately 22 kWh of Sigenergy battery storage to maximise self-consumption. We ensured full compliance with building regulations, electrical standards and industry best practice, obtaining all necessary permits and approvals.
Installation and completion
The installation was carried out with minimal disruption to the day-to-day running of the gurdwara. Panels were securely mounted, connected to the inverter, and integrated with the existing electrical system, before 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.
The results
- Energy cost reduction: lower electricity bills and reduced reliance on grid energy.
- Environmental impact: an estimated 23,750 kWh of clean energy each year, saving an estimated 4.9 tonnes of CO2 annually.
- Financial returns: ongoing energy savings contribute to long-term financial sustainability.
- Public image: demonstrates responsible energy practices to the congregation, staff and the local community.
