An on-grid power plant under 100 kW is a solar photovoltaic (PV) system that connects directly to the electrical grid. It consists of solar panels that generate electricity from sunlight, an inverter that converts this electricity into a form usable by the grid, and metering equipment to measure energy flows. These systems help offset electricity costs by feeding excess power into the grid and typically require minimal maintenance. They are installed in compliance with local regulations and utility standards, offering economic benefits through reduced energy bills and environmental advantages by reducing reliance on fossil fuels.
