Grid-Connected Technology
On-Grid Solar: Generate Solar Power While Staying Connected to the Grid.
Understand how grid-tied rooftop solar works, how net metering offsets monthly billing, when it makes financial sense, and what site conditions must be evaluated before installation.
When On-Grid Makes Sense
- Reliable Grid Availability: Your urban home or commercial building experiences minimal power cuts.
- Primary Goal Is Bill Reduction: You want the quickest financial payback (3 to 4 years) without the high recurring expense of battery replacements.
- Net Metering Feasibility: Your local electricity distribution company (e.g. MSEDCL) allows bidirectional grid export.
When On-Grid Does Not Make Sense
- Frequent Daytime Blackouts: Because of mandatory "anti-islanding" safety relays, on-grid inverters immediately shut down during power cuts to protect utility grid line workers.
- Remote Off-Grid Sites: Properties located outside the distribution grid reach.
- Critical Backup Needs: Medical equipment, data centers, or continuous manufacturing lines that require uninterruptible power.
System Mechanics
How Net-Metered On-Grid Solar Works
1. PV Generation
Solar panels absorb solar irradiance and produce DC electricity during daylight hours.
2. Inversion
The grid-tied inverter converts DC to 230V single-phase or 415V three-phase synchronized AC power.
3. Self-Consumption
Electricity is first routed to power active domestic or factory loads immediately.
4. Grid Export
Any excess unused power flows through the bidirectional net meter, earning units credited on your bill.
