Are you planning to upgrade your home to a solar-powered home? Do you think you have a small home and that’s why you cannot have a solar plant installed? If yes, then a 1kW solar system is the ideal choice for you. A 1kW solar system can easily power a 2-3 BHK house wherein you can use one refrigerator, three fans, one TV, one laptop, and 4-5 lights. On average, you can run about 800 W loads on a regular basis.
The complete solar setup typically includes high-efficiency solar components such as solar panels, solar batteries (off-grid solar plant), solar inverter, mounting structure, and added accessories. After absorbing the sunlight, the solar panels generate DC electricity. It is then converted into AC electricity through a solar inverter to power the appliances in your home. To effectively run your entire home load, you will need both solar power and a solar battery or connection to a grid.
As a homeowner, investing in 1kW solar panels is a great step towards increasing your savings tremendously. If you are wondering how many types of 1KW home solar systems are available in the market today or what the 1kW solar system price is in India, this blog has all the information you need.
Types of 1kW Home Solar System
To cater to the varying electricity needs of customers, there are three different types of solar systems available in India.
- On-grid 1kW Solar System (with grid export)
- Off-grid 1kW Solar System (with Battery Backup)
- Hybrid 1kW Solar System (Solar Battery Storage with Grid Connection)
On-grid 1kW Solar System
Also known as a grid-tied system, an on-grid solar system allows you to draw electricity from both your solar system and the grid. It consists of only two main components — solar panels and a solar inverter. Since the system does not have a device like a solar battery to store the electricity, it does not provide power backup. The electricity is generated from solar panels and passes through the inverter, where it is converted from DC to AC for household use.
If electricity generated is more than your consumption, then excess power will be automatically exported to the utility grid. In this way, you can export extra or unconsumed electricity to the grid and gets compensated for it with days when your consumption exceeds generation. On average, a 1kW on-grid solar system produces about 4-6 units per day depending on your location.
Here are some key highlights of having on-grid 1 kilowatt solar panels at home:
- Since this type of solar system requires fewer components, it is on the affordable side — no recurring costs.
- Electricity is consumed as per the home power requirements.
- Extra power generated is exported back to the grid. Net metering ensures and keep a record of all units exchanged between you and the grid, which reflects periodically in monthly bills.
- The utility grid can be used to draw power in case of less energy generation from the solar system and at time when there is no generation, like night.
Off-grid 1kW Solar System
Also known as a solar system with battery backup, off-grid solar systems are designed for places with no access to grid or when the homeowner wants independence from power outages. This kind of solar system comes with solar batteries and can function effectively independent of the grid connection. The main components include solar PV modules, solar inverter, solar battery (solar battery, normal battery, or lithium ion battery), and the balancing equipment (mounting structure, mc4 connectors, DC wire, DCDB box, and earthing kit).
With this system, the unconsumed electricity does not go back to the grid. Instead, it gets stored in solar batteries. It is a complete power bank in itself and provides a power backup when your solar panels aren’t producing electricity. On average, a 1kW off-grid solar system generates 4-6 units per day.
Here are some key highlights of having off-grid 1 kilowatt solar panels at home:
- Works without a grid; battery is used as the device to store power, and it acts as a grid in itself
- When the solar system does not generate electricity due to a lack of sunlight, the system utilises the stored power to run electrical appliances.
- Ensures reliable power supply
Hybrid 1kW Solar System
The hybrid solar system combines the functionality and features of both on-grid solar systems and off-grid solar systems. While a hybrid system stays connected with the conventional utility power grid, it also contains a battery backup. This allows the user to not only export power back to the grid once your battery and appliances are fully charged but also draw from the grid in times of excess power demand. This type of solar system is recommended when you want a reliable power backup, do away with unexpected power cuts, and reduce energy bills.
Here are some key highlights of having a hybrid solar system at home:
- Excessive energy can be both stored (in the battery) and exported back (to the grid), resulting in no wastage.
- With features like battery backup, its demand stays firm in the market.

Benefits of Having a 1kW Solar System Installed at Home
Solar panels are indeed one of the best ways to ensure self-consumption while cutting down heavily on your energy bills. Not to mention the positive impact solar has on the environment. Here are some of the major benefits a homeowner can enjoy with solar.
- Accessibility as per Your Needs
With three solar model types to choose from, buyers can enjoy greater convenience and advantages. For example, homeowners who opt for 1kW on-grid solar panels can export the excess power generated through the panels to the government grid. When you don’t draw any electricity from the grid due to sufficient solar power generation by your 1kW solar panels, the utility bill will reflect zero charge. On the other hand, those who want to enjoy independence from government grids and be self-sufficient in producing and storing electricity may go for a hybrid or off-grid system. Off-grid systems even work for locations that do not have access to the local grid!
- Reliable Source of Electricity
Since you will be generating your own electricity, you will still have power even when the entire town experiences a power cut. Whether you choose an off-grid system with a battery backup or an on-grid system with accessibility to the local grid, there will always be enough surplus electricity to power your home for hours. In addition, today’s photovoltaic solar panels are better-performing in terms of energy output against the sunlight captured. As a result, fewer panels are needed to generate ample solar electricty.
- Energy Cost Savings
For most homeowners, the cost of fuels and monthly bills can be quite overwhelming. Solar systems can help you reduce your energy bills by up to 70%. With solar powering your home, you get to save small amounts every month, which results in higher profitability in the long run.
1kW Solar System Installation Cost in India
The overall 1kW solar panel price in India depends on the type and number of 1 kW solar panels you want to purchase and how complex it is to install them.
In order to efficiently install a 1kW solar panel system in India, you will need about 100 sq. feet of shadow-free roof space. It will help generate 5 kilowatt hours of energy during the day (for 8-10 hours), enough to meet your entire household’s needs. The power generation capacity can be increased by installing more panels and having the required battery backup. While a steady decline in prices has been noticed in the solar industry — thanks to more and more homeowners going solar — PV arrays are still a significant investment that needs to be done wisely. It is better to always consult a trusted solar company before making a final decision.
Usually, the cost of installation is included within the cost of solar system purchase, so you can just let the solar energy company take care of it.
