An on-grid or grid-tied solar roof-top system is a system that works along with the grid which means that any excess or deficiency of power can be fed to the grid through net metering. Many residential and commercial users are opting for an On-grid solar system as they get a chance to enjoy credit for the excess power their system produces and save on their electricity bills. You will always have power either from the solar system or from the grid. These Type of system do not have batteries.

How on-grid system works?

In an on-grid solar system, solar panels will produce power during the day. This power can either be used instantly or exported to the grid with no backup for power outages. If at any time the system runs out of power, it draws the same from the electricity grid. Hence, a user will never run out of power in this case. Similarly, any excess that is produced by the system is fed to the grid.

 The advantage of an on-grid system is that the user will get a credit in his electricity bill for the extra power he sent to the grid. So, his electricity bills will also reduce. Always assess your Home’s Energy Consumption & Solar Electricity Needs. before installing an on-grid solar system.


The light from the sun falls on the solar panels from where DC electricity is generated. This DC from the sun is converted into AC with the help of the inverter, which is then used by consumers in their homes or any commercial Place i.e factory,shop ,School etc. Till this stage operations of any solar system is the same. The main difference is beyond this point. After the electricity that is consumed by us, there can be two routes for the extra energy generated:

  1. It can be either stored in batteries for use at a later part of the day (off-grid solar system) or
  2. Fed to the grid (on-grid solar system). Based on the feed-in-tariff rates (tariff fixed by the government, for purchase of the solar power generated from solar plants) in your area, your electricity bill is reduced for the amount of power that you have sold to the power grid

Benefits

01

Guaranteed 24*7 power supply

With an option to use either solar power or the main power grid, the consumer will always have access to power and will never suffer from a power outage.
02

Opportunity to earn more

With the help of a net meter installed at your home, you can track the number of units you sent to the power grid and claim a credit for that in your home electricity bill. This forms a lucrative option for the consumers who think of it as an extra opportunity to make money. Almost all the states in the USA and even India have mandated Net Metering.
03

More Savings

The main purpose of installing an on-grid solar system is to reduce your electricity bills. You can adjust the usage depending upon peak demand hours and hence end up paying no peak demand charges. These are the higher rate of charge that the utility charges for using the grid during high-demand hours. Also, you end up paying less on electricity bills and earn more through Net Metering.
04

Good Investment Returns

An on-grid solar system offers a good investment option. It has 3.5 years as payback time and provides free electricity for the More then next two decades. You can convert your own property into a revenue-generating avenue by investing in solar and achieving ROI in just 4-5 years.
05

Works efficiently

The on-grid system works in sync with the grid. There is no limitation in the on-grid system except one i.e it shuts down when power cuts occurs, you can run any home appliance on the grid-tied solar system. . For example, a 2 kW on-grid system can run 8 kW power.it also use 100% of solar power produced from solar panels.
06

Easy to install

Installation of an on-grid system is easy and can be done easily by oneself on the rooftop. It can be easily installed on residential rooftops, rooftops of commercial Places, government organizations, private institutions, etc.
07

Less Costly

Since an on-grid solar system does not require batteries, it is cheaper to install when compared to an off-grid system
08

Less Maintenance

An on-grid solar system involves less maintenance and generally has a longer life when compared to an off-grid system.
09

Subsidies and Other Incentives

A user can avail of government subsidies and other incentives to install on-grid solar systems.

Limitation

*Does not come with backup, the system does not work when there is a power cut.

Primary Components

01

Solar Panel

it is the main components of the on-grid solar system. They comprise more than 50% of the total cost of a solar system and are the components that capture solar energy and convert solar energy into electrical energy.
02

Solar Inverter

This help in converting the DC Current produced from the solar panel into AC supply.
03

Panel Stand

These are also a major component of the entire solar system. Some people do not give much attention to this component and try to save a few bucks by using a low-quality stand. However, remember that this stand will support the solar panels and if the stand is not of good quality, your solar panels could just fall resulting in a heavy loss. It is the skeletal structure holding the panel in the proper position. These stands are generally made of aluminum or galvanized iron.
04

Solar Cable

Solar Cable is the medium through which electricity is transferred from solar panels to the inverter. Generally, there are two types of wires in the market, such as AC Wire and DC Wire
05

DCDB / ACDB

DC Distribution Board(DCDB) is used for connecting the output power from the solar panel to the input of the inverter while AC Distribution Board (ACDB) distributes the electrical power from a solar inverter to the AC load system through an energy meter.
06

Earthing Kit

An earthing kit is used to protect the on-grid solar system from earthing current, it is compulsory for the safety of consumers.
07

Lighting Arrestor

Lightning Arrestor is used to protect the on-grid solar system from lightning at the time of thunder in clouds
08

Net Meter & Solar Meter

Net metering is a special metering and billing agreement between utilities and their customers, which facilitates the connection of small, renewable energy-generating systems to the power grid. It is an important component in an on-grid solar system as it keeps the reading to claim credit in your future electricity bills

On-grid solar system price varies with the selection of brands, quality of products used, and system replacement warranty. Latest price list of the on-grid solar system in India.
