2kW On-Grid Solar System Price in India: Cost, Subsidy, Savings & Complete Guide
A 2kW on-grid solar system is one of the most popular rooftop solar solutions for small homes, apartments, shops, and offices in India. It helps reduce electricity bills by generating solar power during the day and exporting surplus energy to the grid through net metering.
The 2kW on-grid solar system price in India typically ranges between ₹1.2 lakh and ₹1.6 lakh before subsidy, depending on the quality of solar panels, inverter brand, installation requirements, and location. Under the PM Surya Ghar: Muft Bijli Yojana, eligible residential consumers can also receive government subsidy benefits, making rooftop solar more affordable.
In this guide, we’ll explain the cost, subsidy, electricity generation, roof space requirements, savings potential, and whether a 2kW solar system is the right choice for your home.
What is a 2kW On-Grid Solar System?
A 2kW on-grid solar system is a rooftop solar solution directly connected to the electricity grid. It generates power from solar panels during the day, and if your usage is lower than the generation, the excess energy is sent back to the grid through a process called net metering. At night or during cloudy days, electricity is drawn from the grid.
- Capacity: 2 kilowatts (sufficient for small households)
- Type: on-grid (No battery backup)
- Applications: Homes, small offices, shops, small commercial setups

How Does a 2kW On-Grid Solar System Work?
A 2kW on-grid solar system converts sunlight into usable electricity through solar panels installed on the rooftop.
The system works in four simple steps:
Step 1: Solar Panels Generate Electricity
Solar panels capture sunlight and generate direct current (DC) electricity.
Step 2: Solar Inverter Converts Power
The on-grid solar inverter converts DC electricity into alternating current (AC) electricity used by household appliances.
Step 3: Power Is Used by the Home
The generated electricity is first consumed by the appliances running inside the house.
Step 4: Excess Electricity Is Exported to the Grid
If electricity generation exceeds consumption, the surplus power is sent to the electricity grid through net metering, helping reduce future electricity bills.
At night or during low sunlight conditions, electricity is automatically imported from the grid.
