Solar power for Tiverton Endoscopy Unit

Supporting a Sustainable New Build for the NHS

EX2 Group’s Eco-Tech team was appointed to design and install a high-performance solar PV system for the new Tiverton Endoscopy Unit.

A modern healthcare facility providing essential diagnostic services, the new unit required an energy solution that would reduce long-term operational emissions, support rising electrical demand, and align with NHS sustainability commitments.

Our EcoTech division delivered a roof-mounted, grid-connected PV system designed to maximise renewable generation on a challenging, low-pitch roof while ensuring full compliance with healthcare construction standards.

Tailored Design for a Healthcare Environment

Using detailed 3D modelling and PV*SOL simulations, EX2 Group produced a system layout optimised for the building’s southeast orientation and shallow 10° roof pitch. This ensured maximum annual yield while maintaining an unobtrusive aesthetic suitable for a clinical facility.

To meet performance requirements and reduce shading impact, each module was paired with SolarEdge S1000 optimisers. This increases energy harvesting and supports module-level monitoring which is an important advantage for operational reliability.

Quality Installation and Commissioning

Our Eco-Tech team delivered the full installation, testing and commissioning process, ensuring compliance with:

• NHS electrical infrastructure standards
• Grid connectivity requirements
• Local planning and building regulations

The system operates at an impressive 93.2% performance ratio, with shading losses kept to just 3.3%, thanks to precise placement and system modelling.

The installed system is forecast to generate over 29,000 kWh of renewable electricity each year, contributing directly to the unit’s daytime energy demand and helping reduce reliance on grid power.

The PV array reduces carbon emissions by 4.49 tonnes annually, supporting the NHS target of reaching net zero by 2040.

SolarEdge monitoring ensures module-level insight, easier maintenance, and long-term system resilience. The PV array delivers long-term energy savings and positions the new endoscopy unit as a modern, sustainable healthcare build.
