- Intelligent monitoring and maintenance
- Compatibility with large-scale rooftop installations
- Strong performance under Bangladesh’s hot climate conditions
Challenges
Before implementing the solar project, the factory faced several challenges:
Rising Electricity Costs
Large-scale textile production consumes substantial amounts of electricity, leading to increasing operational expenses.
High Demand During Production Peaks
Power demand fluctuates significantly during production cycles, requiring equipment capable of handling load variations.
Harsh Environmental Conditions
High temperatures and humidity can affect inverter performance and reduce equipment lifespan.
Need for Reliable Monitoring
Unexpected system faults may lead to energy losses and increased maintenance costs if not detected early.
Solution
Sunways provided a high-efficiency commercial solar solution featuring:
330kW Rooftop Solar PV System
The project utilizes:
