On grid solar system for home: Why you should choose and how it is different from off grid and hybrid solar system?
The Indian energy consumption landscape is seeing a new turn with solar energy adoption. To support this, the government of India has rolled out multiple incentives and schemes that encourage the usage of solar system solutions for both residential and commercial use.
If you are planning to install on grid solar system for your home and don’t know where to begin with, this blog serves you just right. In this blog, we will dig deep into what on grid solar system is, why you should choose it for your homes, and how you can reduce your electricity bill by using the net metering feature in relation to on grid solar system.
What is an On Grid Solar System?
An On grid solar system, also known as a grid-tied system; generates electricity from sunlight and connects directly to the local electricity grid allowing users to power their homes, reduce electricity bills, and feed the excess electricity back to the grid.
On Grid Solar System for Homes
An on grid solar system for homes consists of several key components:
- Solar Panels
- Solar Inverter
- Mounting Structures
- Bi-directional Meter
- Solar Accessories
The capacity of an on grid solar system for smaller applications, like a home, typically ranges from 2 kW to 10 kW.
Solar System Capacity vs. Subsidy for Indian Households
The power consumption of a household plays a crucial role in determining the required on grid solar system capacity and available subsidy. Here’s a breakdown:
| Monthly Consumption | Required Solar System Capacity | Available Subsidy for On-Grid Solar System |
|---|---|---|
| 0 - 150 units | 2 kW | ₹30,000 to ₹60,000 |
| 150 - 300 units | 2 - 3 kW | ₹60,000 to ₹78,000 |
| 300+ units | Above 3 kW | ₹78,000+ |
- For households consuming 0-150 units per month : A 2 kW system is sufficient, and a subsidy ranging from ₹30,000 to ₹60,000 is available.
- For households consuming 150-300 units per month : A 2-3 kW system is recommended, with a subsidy of ₹60,000 to ₹78,000.
- For households consuming over 300 units per month : A system above 3 kW is necessary, and the subsidy provided is ₹78,000 or more.
Net metering for On Grid Solar System
The on grid solar system works on the concept of net metering. It is a billing mechanism that allows solar energy system owners to add the extra electricity back to the grid and enables them to offset their electricity consumption with the power they generate.
Every month end the bi-directional meter gives an account of units supplied and taken from the grid. If you supplied more than you consumed, those units will be deducted from your bill and vice versa.
Difference between On Grid and Off Grid Solar System: Know how They Differ from Hybrid Solar System
If you are choosing a solar system for your residential energy needs, it is important to understand the difference between on grid solar system and off grid solar system, how they can be beneficial for your needs and requirements, and what are the key considerations to be taken into account.

| System Type | Overview | Energy Storage | Backup Power | Cost |
|---|---|---|---|---|
| On Grid Solar System | Connected to the national grid. Excess power is sent to the grid for compensation (feed-in tariffs or net metering). | No storage required. | No backup power during grid outages (unless there’s storage). | Least expensive. |
| Off-Grid Solar System | Completely independent from the grid. Used in remote areas or by individuals who disconnect. | Requires large storage (batteries). | Batteries provide backup power during grid outages. | Most expensive due to storage costs. |
| Hybrid Solar System | Combines solar power with storage (battery) and/or generator. Can be connected to the grid. | Storage size depends on load requirements. | Batteries or generator provide backup power when the grid is down. | More expensive than on-grid but less than off-grid. |
What are the Limitations of On Grid Solar System?
On grid solar systems have their benefits and limitations. One limitation is that when there's a power outage from the grid, the on grid solar system automatically shuts down. While this may seem like a drawback, on grid solar systems in urban areas with a reliable grid can still meet all your home’s power needs.
The reason for this shutdown is safety. On grid solar system inverters are designed with Anti-Islanding Protection, which stops the system from generating power during a grid failure. This protects maintenance workers from electric shocks while repairing the grid.

FAQs on On Grid Solar System
Q.1 Is on grid solar system worth it?
An on grid solar system can be a worthwhile investment, especially if you're looking to reduce your electricity bills. On grid solar system allows you to generate your own electricity and feed excess power back into the grid for compensation, either through feed-in tariffs or net metering.
Q.2 How many AC can run in 5kW?
The number of air conditioners (ACs) that can run on a 5kW on grid solar system depends on the energy consumption of the AC units. On average, a standard 1.5-ton AC consumes around 1.2-1.5 kW per hour. So, a 5kW on grid solar system could run approximately 3-4 standard 1.5-ton ACs for a few hours, assuming optimal sunlight and ideal conditions.
Q.3 How much does on grid solar panel cost?
The cost of an on grid solar system varies depending on factors like system size, location, and the quality of components. On average, the cost of a 1kW on grid solar system in India ranges between ₹40,000 to ₹60,000, which includes installation and other associated costs.
Q.4 What is the disadvantage of on grid solar systems?
On grid solar system reduce your dependence on the grid but do not completely eliminate it. In most cases, an on grid system shuts down during a power outage. Therefore, you’ll only have electricity during blackouts if you have a backup generator or a hybrid system with battery storage.
Q.5 Is PM Surya Ghar Muft Bijli Yojana on grid or off grid?
The PM Surya Ghar Muft Bijli Yojana is eligible grid-connected rooftop solar program and offers a subsidy up to INR 78000 on On Grid Solar System.
Q.6 Which one is better, on grid or off-grid?
If you are choosing on grid solar system it is beneficial because you don't have to buy an expensive battery backup system to store any excess energy. If you are opting for off-grid means you are not connected in any way to your grid's power system or utility company. For residential purposes it is beneficial to choose on grid solar system to meet your energy requirements.
