Background: Energy Challenges Facing Caribbean Resorts

In sun-rich Jamaica, high utility rates and frequent power outages are major operational hurdles—especially for hospitality businesses. Bayside Resort, a mid-sized beachfront property in Montego Bay, faced two critical issues:

• Soaring Electricity Costs: Round-the-clock energy use for air conditioning, water heaters, lighting, and refrigeration made electricity the resort’s largest recurring expense.
   

• Unstable Grid Supply: Unpredictable power outages disrupted guest experiences, interrupted HVAC systems, stalled elevators, and affected kitchen operations.
   

To overcome these challenges, the resort’s management sought a dependable solar energy solution tailored to their unique load profile and mixed-voltage appliance infrastructure.

Solution: 15KW Split-Phase Hybrid Solar Power System

After an in-depth site audit and load analysis, our engineering team designed and installed a high-performance 15KW hybrid solar energy system with built-in 110V and 220V split-phase output and 30kWh battery storage. The system was tailored to:

• Support both low-voltage (lights, small appliances) and high-voltage (HVAC, pumps, kitchen equipment) loads
   

• Seamlessly switch to battery backup during grid failures
   

• Provide real-time monitoring and remote management
