Overview
Sunways partnered with Grineu Solar to deliver a high-performance commercial rooftop solar project in Samlaya, Vadodara, Gujarat, India. Designed to maximize energy production and system reliability, the project combines high-power PV modules with the Sunways STT-80KTL three-phase on-grid inverter to achieve optimal long-term performance.
The installation features 171 Waaree 590Wp solar modules with a total DC capacity of 100.89kW, paired with a Sunways STT-80KTL commercial string inverter. The solution helps the site reduce electricity costs, improve energy efficiency, and increase renewable energy utilization.
Challenges
As commercial solar projects continue to adopt larger and higher-power PV modules, system designers face several challenges:
Maximizing Energy Yield
High-power modules require inverters capable of handling larger DC inputs while maintaining high conversion efficiency.
Reducing Mismatch Losses
Complex rooftop layouts and varying module orientations can lead to energy losses if the inverter does not provide sufficient MPPT flexibility.
Simplifying Operation and Maintenance
Commercial system owners need fast troubleshooting and remote management capabilities to reduce maintenance costs and minimize downtime.
Supporting Future Expansion
The system must remain compatible with evolving module technologies and future project upgrades.
Solution
To address these requirements, the project adopted the Sunways STT-80KTL three-phase on-grid inverter as the core power conversion solution.
The STT-80KTL is specifically designed for commercial and industrial solar applications, providing high-efficiency power conversion, flexible PV configuration, and intelligent monitoring capabilities.
Combined with 171 high-power 590Wp PV modules, the inverter enables stable operation, higher energy production, and long-term reliability.
