Challenges, solutions and lessons learned

Challenge
Existing electrical installations varied significantly between the four mosques, including dual supplies, undersized fuses and legacy wiring.

Solution
Each site underwent detailed pre-installation surveys, with electrical infrastructure upgraded before renewable technologies were installed.

Challenge
Delivering works within live places of worship.

Solution
Activities were carefully programmed around the five daily prayer times, Friday Jumu’ah services and community events, with high-impact works paused before the Adhan and safe access maintained throughout.

Compliance and certifications

Overview

CEN delivered a turnkey programme across four South Wales mosques for YnNi Teg Cymru with the Bengal Dragons Foundation, installing Solar PV and battery storage engineered to reduce operational costs and carbon footprints for community-focused organisations.

Each site is a live place of worship, with its own schedule, community activity and legacy electrical condition — see Project challenges below for how CEN planned around each.

Measures and technologies

  • Solar PV — roof-mounted across four sites, total >52kW installed capacity
  • Battery Storage — lithium-ion, total 81kWh across the portfolio
  • Immersion diverters — divert excess solar to hot water cylinders for ablution (Wudu) and cleaning facilities
  • Roof inspection and remediation (structural integrity prior to installation)
  • Electrical safety upgrades where dual supplies, undersized fuses or unsafe legacy wiring were identified
  • G99/DNO applications managed by CEN
