CASE STUDY

Heartlands Hospital

Heartlands Hospital needed to strengthen its sustainability efforts and reduce its environmental impact as part of the NHS’s commitment to achieving Net Zero. To support this, Heartlands Hospital partnered with us to install a rooftop solar PV system. The project was carefully delivered to enhance energy efficiency and cut carbon emissions without disrupting vital hospital operations.

Challenge

 

As a busy, security-sensitive site, any installation work had to follow strict permit-to-work rules, tight delivery schedules, and robust operational controls to ensure no disruption to vital healthcare services.

On top of this, the project required a G100 export limitation and control system to be integrated with the existing Combined Heat and Power(CHP) unit.

 

Our team undertook comprehensive portfolio reviews, desktop studies, technical due diligence, and financial feasibility assessments to develop the most effective solution.

 

Following a detailed site survey and design phase, we delivered planning drawings and managed the G99 application to secure grid approval.

 

The installation involved fitting 944 solar panels, fully wired and connected to a custom G100 control system synchronised with the hospital’s CHP unit.

We carefully planned each phase to comply with security protocols and hospital operational needs, ensuring safe and timely deliveries and installations.

 

After advising the team of the importance of fire safety with solar, especially with the nature of the property, they opted to use a SolarEdge solution due to its DC isolation and fire alarm integration capabilities.

 

In addition, we carried out an Operations & Maintenance survey on the hospital’s existing solar PV assets and proposed remedial works to maximise their performance.

Heartlands Hospital’s new 401.2 kWp solar PV system now provides 100% onsite usage, producing approximately 367,870 kWh of clean electricity each year.

 

This estimated carbon saving of over 72,500 kg CO₂e in the first year significantly contributes to the NHS’s Net Zero goals.

 

With this success, the hospital is exploring further solar installations across additional buildings in the estate, reinforcing its commitment to sustainable healthcare for the future.
