Overview of On-Grid Solar Systems

An on-grid solar system (also known as a grid-tied system) is directly connected to the electricity grid. It’s the most popular choice for Indian households with a stable grid connection.

At Perfect Sunwin Solar, we specialize in on-grid rooftop solar systems for both independent homes and housing societies.

Components of an On-Grid Solar System

  • Solar Panels – Capture sunlight and generate DC electricity.

  • Solar Inverter – Converts DC electricity into AC power for home use.

  • Mounting Structures – Robust, weather-resistant supports for solar panels.

  • Bi-directional Meter – Tracks power supplied to and imported from the grid.

  • Solar Accessories – Cables, DC/AC combiner boxes, and safety connectors.

 

How an On-Grid Solar System Works

The process of power generation in an on-grid solar system is simple:

☀️ Solar Panels absorb sunlight → generate DC electricity

Solar Inverter converts DC into AC power

📟 Bi-directional Meter feeds AC power to your home

🏡 Excess electricity is sent to the grid

🌙 At night, electricity is imported back from the grid

 

Key Components Explained

1. Solar Panels

Installed on rooftops facing south, solar panels capture sunlight and generate DC power.

2. Solar Inverter

Converts DC power into usable AC electricity, which runs household appliances.

3. Mounting Structures

Durable, galvanized steel frames designed to withstand storms, heavy rains, and last 25+ years.

4. Solar Accessories

Includes AC/DC cables, combiner boxes, MC4 connectors, and earthing wires for safety and reliability.

5. Bi-Directional Meter

Monitors both imported and exported electricity, ensuring accurate billing through net metering.


Net Metering & Billing

With net metering, your monthly bill shows:

  • Units generated by your solar system

  • Units consumed by your home

  • Surplus units exported to the grid

  • Units imported back from the grid

👉 If you generate more than you consume, your bill goes down further.


Benefits of On-Grid Solar Systems

  • Reduces monthly electricity bills significantly

  • No need for expensive batteries (the grid acts as backup)

  • Investment pays back in 3–5 years, after which electricity is free for 20+ years

  • Easy monitoring of consumption and savings

  • Government subsidies available (for residential DCR panel systems)

  • Most cost-effective among all solar system types


Power Outages & Safety

During a grid power cut, on-grid solar systems automatically shut down. This is due to a built-in safety feature called Anti-Islanding Protection — designed to protect grid maintenance workers from electrical shocks.

While this may seem like a limitation, in urban areas with reliable electricity supply, on-grid solar remains the most practical and economical solution.


Types of On-Grid Solar Systems by Capacity

📌 1 kW System → ~1400 units/year → saves ~₹11,200 annually
📌 2 kW System → ~2800 units/year → saves ~₹22,400 annually
📌 3 kW System → ~4200 units/year → saves ~₹33,600 annually
📌 5 kW System → ~7000 units/year → saves ~₹56,000 annually
📌 10 kW System → ~14,000 units/year → saves ~₹1,12,000 annually

💡 Savings are calculated with an average tariff of ₹8 per unit.

On-grid solar system price without subsidy

The price range of an on-grid solar system depends on many factors. It varies based on:

  • The type of solar panels
  • The type of inverter
  • The type of panel mounting structures
  • Whether the solar installation company provides a maintenance service with the installation
  • Product variant (including the guarantees and warranties provided by the installer)

Here’s a reference table concerning the price range of a grid-tied solar system

The capacity of the solar system

Cost of the solar system

2Kw

₹1.51L to ₹2.28L (without subsidy)

₹0.91L to ₹1.68L (with ₹60,000 subsidy)

3kW

₹1.92L to ₹2.63L (without subsidy)

₹1.14L to ₹1.85L (with ₹78,000 subsidy)

4kW

₹2.4L to ₹3.19L (without subsidy)

₹1.62L to ₹2.41L (with ₹78,000 subsidy)

5kW

₹2.87L to ₹4.14L (without subsidy)

₹2.09L to ₹3.36L (with ₹78,000 subsidy)

7kW

₹4.21L to ₹5.39L (without subsidy)

₹3.43L to ₹4.61L (with ₹78,000 subsidy)

10kW

₹5.59L to ₹7.08L (without subsidy)

₹4.81L to ₹6.30L (with ₹78,000 subsidy)

The government of India offers a subsidy on the installation of a solar system, but there are a few conditions:

  • The subsidy is offered for the installation of a solar system for residential installation only.
  • The subsidy is applicable only for made-in-India (dcr) solar panels.
  • The subsidy is capped at ₹78,000 for on-grid solar systems above 3 kW when the average monthly electricity consumption will be more than 300 units
Subsidy for homeowners
New rates for subsidy on solar panel systems

For 1-2 kW systems: ₹30,000 to ₹60,000

For 3 kW systems: ₹78,000

  • ₹60,000 for 1st 2 kW
  • ₹18,000 for the next 1 kW

The rates of govt subsidy on solar under the new scheme are capped at ₹78,000 for systems above 3 kW when the average monthly electricity consumption will be more than 300 units.

 

Here is an example calculation for your reference:

System size

New subsidy rates (for applications filed on or before February 13, 2024)

1kW

₹30,000

2kW

₹60,000

3kW

₹78,000

5kW

₹78,000

 

Subsidy for housing societies

Under the PM Suryaghar Muft Bijli Yojana, RWAs or housing societies can get subsidy upto ₹18,000/kw for common facilities usage (upto 500kw).

 

ROI on the On-Grid Solar System in India

The return on investment (ROI) of an on-grid solar system depends on several factors: the type of solar panels you choose, the amount of sunlight your home receives, the discovered tariff (L1 rate) in your state, and more.

Let’s break it down with an example:

👉 Suppose you install a 5 kW solar system worth ₹2,80,000 (after subsidy).
👉 The electricity tariff in your state is ₹8/unit.
👉 Your average monthly power consumption is 580–600 units.

Without Solar

Your electricity bill would be around ₹4,640 to ₹4,800/month.

With Solar

A 5 kW solar system generates about 580–600 units/month on average.

  • Slightly higher during summer months

  • Slightly lower during the monsoon season

This means almost all your power requirements are covered by solar. In many cases, your monthly electricity bill may drop close to ₹0.

Savings

  • Monthly savings: ₹4,640 – ₹4,800

  • Yearly savings: approx. ₹55,680

  • Payback period: 4 to 5 years (initial investment recovered)

  • Total savings in 20 years: more than ₹11,69,280

And remember — electricity tariffs rise by 3–5% every year. So, your actual savings will be even higher.

FAQs

1. What is an on-grid solar system?
An on-grid solar system is connected to the electricity grid using a net meter.

  • During the day, extra electricity is sent to the grid.

  • At night, when panels aren’t producing, you can draw electricity back from the grid.

2. How does an on-grid system work?

  • Solar panels convert sunlight into DC power.

  • A solar inverter converts DC to AC power.

  • AC power runs your appliances.

  • Extra energy is exported to the grid through the net meter.

  • Imported energy is pulled back at night or when demand exceeds generation.

3. Which is better – On-grid or Off-grid?

  • If you live in urban areas with a reliable grid: go for on-grid.

  • If you live in rural areas without a stable grid: an off-grid system is the solution.
