On-Grid Solar System

An on-grid solar system (a.k.a. grid-tied or grid-connected system) links rooftop solar panels directly to the local electricity grid. You use solar-generated power in real time and export any surplus to the grid. When solar output dips (e.g., at night), you seamlessly draw from the grid—no batteries required. This simplicity, cost-effectiveness, and compatibility with net-metering policies make on-grid the most popular solar solution in urban India.

Get Started

Pieces That Make Your Solar System Work

Each part of an on-grid solar system works together to efficiently convert sunlight into usable electricity and manage energy flow between your home and the grid.

Solar Panels Photovoltaic (PV)

Solar Panels Photovoltaic (PV) modules that convert sunlight into direct-current (DC) electricity.

Grid-Tie Inverter

Grid-Tie Inverter Converts DC from panels into alternating-current (AC) for home appliances and synchronizes output to grid voltage/frequency.

Bi-Directional Meter

Bi-Directional Meter (Net Meter) Tracks energy imported from and exported to the grid, enabling net-metering credits.

Mounting Structure

Mounting Structure & Cabling Roof- or ground-mounted rails plus DC/AC wiring.

Utility Grid Connection

Utility Grid Connection Standard distribution lines; act as both backup source and energy sink.

Note*

All components work in concert to ensure seamless power flow and accurate accounting of imports/exports.

Installation Process: From Rooftop to Power-On

Setting up an on-grid solar system is a streamlined process handled by certified professionals—ensuring safety, efficiency, and compliance at every stage.

01
Site Assessment & Load Analysis

Evaluate rooftop space, sunlight exposure, and household electricity needs.

02
System Design & Component Selection

Choose panel capacity, inverter type, and mounting setup based on your site and budget.

03
Regulatory Approvals

Secure roof owner consent, structural safety clearance, and a grid-connection agreement from DISCOM.

04
Mounting & Electrical Work

Install panels on mounting structure, connect DC/AC wiring, and position the inverter.

05
Net Meter Installation & Commissioning

DISCOM installs a bi-directional net meter; final inspections are done before system is switched on.

06
System Activation & Subsidy Application

Once operational, apply for subsidy disbursement via state or national portals (if applicable).

Cost & Government Subsidy

System Cost Factors

Capacity (kW), panel efficiency, inverter quality, mounting complexity, installation charges.

* Subsidies and low-interest loans dramatically reduce net outlay, boosting project viability.

Government Incentives

Under MNRE schemes, residential rooftop systems (≤3 kW) often get ~30% capital subsidy; larger systems and institutional installations may receive higher rates. Applications and disbursement occur via state DISCOM portals or national online platforms.

Bright Benefits: Why Go On-Grid?

Step into the future of energy with an on-grid solar system—designed to cut your bills, earn you credits, and power your home with clean, reliable sunlight.

  • Lower Electricity Bills: Generate your own power; reduce imports.
  • Net-Metering Credits: Exported units offset grid consumption costs.
  • High ROI: Typically pays back within 5–7 years in India.
  • Low Maintenance: No batteries to maintain; occasional panel cleaning and inverter checks suffice.
  • Eco-Friendly: Zero emissions during operation; cuts carbon footprint.

Operation & Maintenance

A well-installed on-grid solar system needs minimal maintenance—just a few routine checks to ensure optimal energy output and system safety.

Panel Cleaning
Keep it clear, keep it efficient

Dust, bird droppings, and pollution can reduce output—clean panels every 3–6 months for peak performance.

Inverter Health Check
The brain of your system

Schedule an annual inspection to ensure smooth DC-to-AC conversion and update firmware if needed.

Performance Monitoring
Know your power anytime, anywhere

Track energy generation and detect issues early through mobile apps or online portals provided by your installer.

Cable & Mounting Inspection
Secure connections for safe operation

Check for loose wires, rusted mounts, or signs of wear to avoid safety or efficiency issues.

AMC (Annual Maintenance Contract)
Worry-free upkeep by professionals

Most solar providers offer affordable AMC plans that cover regular service, inspections, and priority repairs.

Any Questions

Frequently Asked Questions

It’s a rooftop PV setup tied to the grid. Panels generate DC → inverter converts to AC → supplies home loads; surplus exports to grid, deficits import from grid2.

No. For safety, grid-tied inverters shut off when they detect a power cut; there’s no backup unless you add batteries and a hybrid inverter.

Credits earned when your system exports surplus units to the grid. They offset costs of any electricity you draw later, lowering your net bill.

Yes—especially if you have reliable grid supply. You benefit from lower bills, net-metering credits, minimal maintenance, and fast ROI.

No. On-grid systems work without batteries, which keeps capital costs down. Batteries only add backup capability, turning it into a hybrid system.

Prices vary by capacity (1 kW–10 kW+), panel/inverter quality, and installation complexity. After subsidies, net costs often drop by 25–40% from the gross quote.

Apply via your state DISCOM’s rooftop solar portal or the national MNRE platform. You’ll need technical & structural approvals, then DISCOM will process subsidy disbursement post-commissioning.

Payback usually occurs in 5–7 years, depending on your energy consumption, tariff rate, local solar irradiance, and system cost.
