1. System Hardware & Solar Topologies
Explore how On-Grid, Hybrid, and Off-Grid solar systems operate in practice, compare their key hardware components and subsidy eligibility, and inspect live hardware telemetry.
On-Grid Solar System
An on-grid solar system works in direct synchronization with your local electricity board (DISCOM) grid. It generates clean solar energy during the day to run your home appliances and automatically exports any surplus units through a bi-directional Net Meter. At night or during overcast weather, you seamlessly draw banked power credits from the grid.
How an On-Grid Solar System Works
A 5-step synchronized cycle connecting rooftop solar modules to the national utility grid via a smart bidirectional net-metering interface.
Daylight Solar Generation
High-efficiency N-Type TOPCon bifacial panels capture sunlight and generate clean direct current (DC) electricity.
High-Efficiency Inversion
The on-grid string inverter converts DC power to 230V/415V AC electricity synchronized with the grid frequency and voltage.
Instant Self-Consumption
Your active household appliances (fans, lights, ACs, refrigerators) consume solar power first, reducing grid power consumption to zero.
Surplus Net-Meter Export
Excess units not consumed by your home are automatically exported to the DISCOM grid through a Bi-Directional Net Meter, banking financial units.
Nighttime Grid Banking
At night, power is imported from the grid. At the end of the billing cycle, DISCOM offsets your import against exported units for near-zero bills.
