The challenge

Unreliable grid power and escalating electricity tariffs frequently disrupted hospitality operations and guest services at Ganzevlei Manor. Operating as an Air B&B establishment, the property required a stable, independent energy solution to ensure guest comfort, prevent operational downtime, and safeguard year-round accommodation revenue.

The SSS solution

Specialized Solar Systems engineered an off-grid solar energy solution featuring a ground-mounted 44 kWp bifacial solar PV array and 80 kWh of Freedom Won battery storage. Power conversion is managed by three 15 kVA Victron Quattro inverters (45 kVA total) and two 20 kW Fronius inverters, supported by an integrated 20 kVA three-phase backup generator.

Results and benefits

The system delivers an estimated daily solar yield of 160 kWh/day, ensuring zero power disruptions during peak tourist seasons. The installation provides complete energy independence, lowers the property’s carbon footprint, and achieves an estimated payback period of under 4 years
