Location: Mauritius
Project Type: Resort Hotel (Hospitality & F&B)
System Size: 120kW Hybrid PV System
Solution Provider: ANSO Power
Project Background
In Mauritius’ competitive hospitality sector, managing energy costs while maintaining high service standards remains a constant challenge.
For a 50-room premium resort, rising electricity expenses and continuous energy demand from HVAC, kitchens, and guest facilities created increasing pressure on operational margins.
To address this, the hotel partnered with ANSO Power to implement a 120kW hybrid solar system—designed not to replace the grid entirely, but to strategically reduce energy costs, improve reliability, and support long-term sustainability goals.
System Design & Technical Approach
Following a comprehensive on-site energy audit, the system was designed based on the hotel’s actual load profile and operational patterns.
With a clear concentration of energy demand during daytime—primarily driven by HVAC and kitchen operations—the 120kW PV system was sized to maximize self-consumption during peak solar production hours, ensuring optimal return on investment without unnecessary oversizing.
The system operates under a “self-consumption first” strategy, where:
Solar energy is prioritized for on-site usage
Excess generation is stored in the battery system
The grid remains as a stable supplementary power source
Key components:
1. ANSO High-efficiency N-type TOPCon Bifacial Solar Modules(190pcs x 630W)
Selected to maximize energy yield under Mauritius’ strong solar irradiation, delivering higher generation efficiency compared to conventional modules.
2. Deye Hybrid Inverter (3 x 40kW)
Enables seamless coordination between solar, battery, and grid power, ensuring stable and flexible system operation. Featured with 100% unbalanced output and max. 100A charging/discharging current. It supports max. 10 pcs parallel and multiple batteries in parallel connection, making the system expand the total capacity in the future.
3. ANSO High-voltage Lithium Battery (2 Clusters x 176.8kWh)
Battery Module: 51.2V 314Ah
Battery Cluster: 11* Battery Module, 563.2V 314Ah(with 1 HV Box)
Cycle Life: 6000 Cycles @80% DOD
Adopting top-brand battery cells, LiFePO4 cathode material for high safety, reliability, and long cycle life. Equipped with an intelligent battery management system (BMS), it can automatically manage the charge and discharge status, providing comprehensive battery protection.
Results: Significant Cost Savings & Operational Benefits
Since the system’s commissioning 12 months ago, it has achieved transformative results.
1. Substantial Reduction in Electricity Costs
The 120kW solar system generates an average of 219,000 kWh of clean energy annually, meeting 62% of the hotel's total electricity demand. This has translated to approximately MUR 1.4 million (USD 30,222) in annual savings, effectively reducing the hotel's energy-related operational costs by 60%.
2. Stable Backup Power for Critical Loads
The hybrid system's integrated battery storage ensures an uninterrupted power supply during outages. The Energy Management System (EMS) switches to battery power within milliseconds, keeping critical loads (reception, lighting, essential appliances) fully operational. This reliability safeguards guest satisfaction scores and prevents revenue loss during grid failures.
3. Alignment with Sustainable Tourism Goals
Beyond cost savings, the solar system has helped the hotel reduce its carbon footprint by approximately 120 tonnes of CO₂ annually. This achievement strengthens the hotel's position as an eco-conscious destination, aligning with Mauritius' national commitment to renewable energy and the growing global demand for sustainable travel. The hotel now leverages its solar installation as a marketing tool, highlighting green initiatives to attract environmentally aware guests.
Financial Perspective
Estimated payback period: 4-5 years
10-year cumulative savings: Over USD 300,000
This makes the system not only an environmental upgrade, but a high-return financial investment.
Future Expansion Potential
The current 120kW hybrid system has been designed with scalability in mind. As the hotel’s energy demand evolves and on-site renewable adoption continues to grow, the system can be expanded in a phased approach.
Future upgrades may include:
- Increasing PV capacity to further offset daytime consumption
- Expanding battery storage to enhance peak shaving and backup capability
- Integrating additional loads such as EV charging infrastructure
This modular design ensures that the initial investment remains protected, while providing the flexibility to transition toward a higher level of energy independence over time.
