How Solar + Battery Storage Works

3

Solar Generation

Photovoltaic modules convert sunlight directly into DC electricity through semiconductor technology. Advanced inverters then convert DC power to AC electricity compatible with grid transmission and distribution systems.

Intelligent Controls

Sophisticated control systems optimize charge and discharge cycles based on real-time price signals, grid curtailment avoidance, and ancillary service requirements.

2

Energy Storage Integration

Battery Energy Storage Systems (BESS) capture excess solar generation during peak production hours and strategically dispatch stored energy during highprice periods or peak demand events, optimizing revenue capture.

Grid Integration

Direct interconnection at transmission substations with comprehensive SCADA and Energy Management Systems enabling advanced monitoring, forecasting, and automated market dispatch.
