The client faced difficulties securing a network connection for their solar PV system. Westwood Energy was engaged to design, install, and maintain a solution that would maximise module capacity despite the limitations of the existing inverter and network constraints.
144.5kW | Exeter
OVERVIEW
Westwood Energy successfully installed a 144.5kW solar PV system on a poultry unit in Exeter, overcoming significant challenges with the Distribution Network Operator (DNO). After years of unsuccessful applications to Western Power, we secured a network connection for 85kW (the maximum AC connection capacity), demonstrating the advancements in solar technology.

THE BRIEF
WHAT WE INSTALLED
340 Modules: Trina Vertex 425W
Inverters: 1 x 90K SolarEdge
Optimizers: 340 x P850 SolarEdge
Mounting System: Sunfixings MRD S
Metering Solution: SolarEdge G100
AC Limitation Device: SolarEdge AC Limitation Device
HOW WE DID IT
Through detailed discussions and design approvals with the DNO, we utilised SolarEdge’s advanced technologies to “overdrive” the system and implement AC output limits. This allowed us to install 144kW of module capacity with a 90kW inverter restricted to an 85kW output, showcasing significant progress in solar industry capabilities over the past 12 years.
OUR RESULTS
The installation generates 135MWh annually, with 85% of the energy consumed on-site and 38% of import demand offset. This results in annual savings of approximately £38,000, delivering a strong return on investment and substantially reducing the client’s energy costs.
