315 kWp PSDS-Funded Carport for NHS Foundation Trust
An NHS Foundation Trust in the South West used PSDS Phase 3b funding to deliver a 315 kWp solar carport over a 250-bay staff and patient car park. Generation now offsets ~268,000 kWh/yr of grid electricity; the £148k annual saving is reinvested directly into the Trust's energy hardship fund for low-income outpatients.

Challenge
PSDS funding rounds have strict timing windows — the Trust had 18 months from award to project completion. The site sits adjacent to a maternity unit, requiring zero-noise overnight working and full DBS-cleared personnel. Existing rooftop solar (340 kWp) already used most of the available DNO export capacity, so the new carport had to be designed for ~90% self-consumption.
Our Approach
- PSDS Phase 3b application — submitted and won £950k capex grant covering 100% of project cost
- G99 application redesigned for higher self-consumption via dynamic load matching with HVAC and sterilisation loads
- Build window scheduled around hospital operational priorities — no work during major elective surgery slots
- All personnel enhanced DBS cleared; safeguarding lead present during build
- Tier-1 JinkoSolar Tiger Neo 575W panels with Sungrow SG110CX inverters
- 18 × 22 kW EV chargers prioritised for non-emergency patient transport vehicles

"The PSDS funding made this a no-brainer commercially. What we didn't expect was how much staff value the sheltered parking — winter sickness absence on overnight shifts has measurably dropped."
