300 kWp + 250 kWh NHS Hospital Solar & Battery

The 650-bed acute hospital consumed over £950,000 in electricity annually, with HVAC and medical equipment accounting for 62% of total demand. The roof was densely occupied with chiller plant, exhaust ventilation, and fire evacuation routes. The estates team needed a solution that delivered measurable cost savings without any risk to patient safety or HTM 06-01 compliance.

Bee Solar conducted a LiDAR drone survey and produced a 3D CAD layout that recovered 68% usable roof area by designing elevated mounting frames above chiller plant and preserving all fire evacuation walkways. A 300 kWp array was paired with a 250 kWh LFP battery. The EMS isolates 45% battery reserve for emergency backup while cycling 55% for daily peak shaving. All designs were reviewed by an independent electrical consultant and fully compliant with HTM 06-01.
