A solar power plant designed for high performance and long-term value. While a portion of the energy supports the shopping mall’s daily operations, 70% is fed into the grid — creating a reliable revenue stream. Strategically positioned to deliver strong energy output and commercial returns, the project strikes the perfect balance between sustainability and profitability. A true win for every stakeholder involved.

This rooftop solar power plant proves that smart design beats convention. Despite the unconventional layout, including panels placed on north-facing slopes with a shallow 4-degree tilt, the system is cleverly angled to capture southern sunlight. The result? Remarkable energy generation — on par with standard south-facing setups.

This commercial-scale energy storage system features a 400 kWh capacity, paired with a 500 kWp solar generator. At the heart of the project is an advanced Energy Management System (EMS), which intelligently coordinates energy sources to maintain system stability. Even during peak loads, the EMS ensures smooth transitions and uninterrupted operation — delivering reliable performance when it matters most.
