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.

2. Comparative Engineering Analysis

Review how WayTara's pre-engineered unified topology eliminates voltage clipping, multi-vendor finger pointing, and switchover lag found in traditional installations.

Instant Sub-20ms Blackout Resilience

Integrated BESS acts as a power buffer: Discharges stored solar energy during simultaneous fleet charging spikes, keeping grid draw steady and low.

Traditional Multi-Vendor Pitfall

Charging dozens of commercial EVs simultaneously causes grid transformer overloads and hefty maximum demand surge fines.

Maximum Solar Tariff Optimization

Fueling vehicles directly with rooftop and canopy solar generation drops effective per-unit electricity cost to ~₹2.20/kWh.

Traditional Multi-Vendor Pitfall

High DISCOM EV charging tariffs (₹8.50 – ₹11.00/kWh) eat into fleet operating profit margins.

Single Accountable Warranty SLA

OCPP 2.0.1 cloud software with RFID automated driver authentication, fast billing, and fleet telematics integration.

Traditional Multi-Vendor Pitfall

Driver downtime and lack of centralized charging telemetry across hundreds of delivery vehicles.

5. Frequently Asked Questions

8 Core Architectural & Subsidy Answers

Consolidated engineering, pricing, battery sizing, AC compatibility, and PM Surya Ghar subsidy answers for On-Grid, Hybrid, and Off-Grid solar systems.

An On-Grid system works in direct synchronization with the DISCOM grid to export surplus power via a bi-directional Net Meter for bill credits, but shuts down during power cuts for lineman safety. A Hybrid system (WayTara Flagship) provides the best of both worlds: full DISCOM net-metering plus a smart Lithium (LFP) battery bank that switches on in sub-20ms during power cuts with zero flicker. An Off-Grid system is a 100% standalone microgrid with zero grid connection, relying entirely on high-capacity LiFePO4 batteries for 24/7 power in remote locations.
