An off-grid solar system (solar roof-top system with battery bank) is a system that works does not work along with the grid which means that any excess or deficiency of power can not be fed to the grid through net metering. It fed directly to the batteries that is connected with the system. Many residential and commercial users are opting for an Off-grid solar system as they get a chance to enjoy the self generated electricity and does not want to depend on the grid or discom and save on their electricity bills as they do not need to use electricity from the grid for their appliences to be run. You will always have power either from the solar system or from the batteries. These Type of system does not depend on grid electricity .

How off-grid system works?

In an off-grid solar system, solar panels will produce power during the day. This power can either be used instantly or exported to the Batteries and  backup for power outages. If at any time the system runs out of power,then only it draws the same from the electricity grid and only for that consumption you need to pay electricity bill. Hence, a user will never run out of power. Similarly, any excess that is produced by the system is fed to the batteries connected with it.

 The advantage of an off-grid system is that the user has their own self generated electricity and does not relay on the discom/grid electricity, also user has no tension of any power cuts.  Always assess your Home’s Energy Consumption & Solar Electricity Needs. before installing an off-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 is one routes for the extra energy generated:

1. It can be stored in batteries for use at a later part of the day (off-grid solar system).

Benefits

01

Guaranteed 24*7 power supply

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

More Savings

The main purpose of installing an off-grid solar system is to get rid of your electricity bills and power cuts.
03

Good Investment Returns

An off-grid solar system offers a good investment option. It has 5.5 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 5-6 years.
04

Works efficiently

The off-grid system works independently with batteris. There is no limitation in the off-grid system unless you have not miscalculated your solar requirement.
05

Easy to install

Installation of an off-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.also it takes much less time for commissioning as compared to on-grid 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 30% 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 and also responsible for running the load.
03

Batteries

it is also the main components of the off-grid solar system after solar pannels. They also comprise around 30% of the total cost of a solar system and are the components that contain excess electricity generated by the solar panel
04

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.
05

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
06

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.
07

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.
08

Lighting Arrestor

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