1 kW Solar System Price in India with Subsidy

1 Kilowatt Solar Panel System Price in India with Subsidy

1 kW Solar System Price in India with Subsidy

A 1 kW solar system generates 120 to 180 units of electricity monthly. Therefore, it is most suitable for small households or Kirana shops with a certain budget limit or low energy requirements. On fulfilling PM Surya Ghar Subsidy criteria, you can even get a subsidy of Rs. 30,000 and reduce the out-of-pocket 1 kW solar system price.

Here we have covered the detailed breakdown of this small capacity solar panel installation price so that you can make your budget planning accordingly.

Detailed Breakdown of 1 kW Solar Panel System Price in India

The costliest components in a 1 kW solar system are solar panels, solar inverters, solar battery and mounting structure. You need no battery in an on-grid system, therefore, the cost also stays lower than off-grid and hybrid solar system. Plus, solar panels, the lightning arrester and several other components also influence the cost of a 1000-watt solar system.

Key Factors Influencing Cost of 1 kW Solar Panel Price in India

The cost of solar panels depends on 2 main factors:

  • The Technology of The Panels
  • DCR / non-DCR Certification

Here’s how these factors affect a solar panel’s cost:

1. Solar Panel Technology

Solar panels are continuously evolving with upgraded technologies. Each upgrade comes with new features and higher efficiency. The cost of a solar panel varies according to its technology. 

Curious about which company’s solar panels you should buy? Read our blog on top solar companies in India.

2. DCR vs Non-DCR Solar Panels

1 kW solar panel price depends on where the cells and panels were made and sourced from. This is because solar cells imported from abroad are cheaper than the ones made in India. 

You may think it is best to buy the cheapest solar panels, that is, solar panels with cells made abroad. But then you will miss out on government subsidies.

The PM Surya Ghar subsidy is only available for on grid solar systems with DCR-certified panels. You can learn more about on grid solar systems on my website.

Depending on whether a panel is DCR or non-DCR, here’s how much they cost:

Solar Panel Types 

Average Price (Non-DCR)

Average Price (DCR)

Mono-PERC Half Cut (550 W)

Price: Rs. 11,000 to Rs. 12,000

Per Wp Price: Rs. 20 to Rs. 21.81

Price: Rs. 12,500 to Rs. 13,500

Per Wp Price: Rs. 22.72 to Rs. 24.54

Mono-PERC Half Cut Bifacial (550 W)

Price: Rs. 12,000 to Rs. 13,000

Per Wp Price: Rs. 21.81 to Rs. 23.63

Price: Rs. 14,000 to Rs. 15,000

Per Wp Price: Rs. 25.45 to Rs. 27.27

TOPCon Bifacial (N Type) (570 W)

Price: Rs. 14,000 to Rs. 15,000

Per Wp Price: Rs. 24.56 to Rs. 26.31

Price: Rs. 15,500 to Rs. 16,000

Per Wp Price: Rs. 27.19 to Rs. 28.07

Monthly Savings and Electricity Generated by a 1 kW Solar System

Daily, a 1 kW system with mono-PERC half-cut solar panels can generate 4 to 6 units of electricity. Electricity generated depends on the radiation the panels receive.

You can expect generation of 120 to 180 units of electricity monthly.

Here’s a table which shows the electricity and savings generated by a 1 kW solar system.

Capacity of Solar System

Monthly Electricity Generation

Monthly Savings (Assuming    Tarrif = Rs.8/Unit)

1 kW

120 to 180 units

Rs. 960 to Rs. 1,440

But what if your monthly electricity consumption is over 600 units of electricity monthly? In that case, you can install a 5 kW solar system. We have information about the installation cost of a 5 kW solar system with a subsidy on our blog.

Solar Components Required with 1 kW Solar Panel

Here’s a list of major components of a 1 kW solar system:

1. Solar Panels

The solar panels receive the sun’s radiation and convert it into solar electricity. The efficiency of a home solar panel system depends on the panel’s technology.

2. Inverter

The electricity generated by a solar panel is Direct Current (DC). A solar inverter converts this DC power into Alternating Current (AC). You can learn about the best solar inverters for your home on our blog.

3. Mounting Structure

A mounting structure has to be strong enough to hold your solar panels for 25-30 years. A mounting structure made of galvanised zinc is better due to its strong resistance to corrosion.

To learn about the different kinds of mounting structures you can use, you can read my blog on types of mounting structures.

4. Net Meter

An on-grid system stays connected to a DISCOM’s grid to export solar electricity to the grid. To measure the electricity exported and consumed from the grid, you have to install a net meter. 

Note: Net metering is necessary only in 1 kW on-grid and hybrid solar system, not in off-grid solar system.

5. ACDB Box

ACDB protects your appliances and inverter. The ACDB box is located between your inverter and the appliances. An ACDB box saves appliances from voltage fluctuations by using a Surge Protection Device (SPD) and MCCB (Molded Case Circuit Breaker).

6. DCDB Box

The DCDB box is located between the solar panels and the inverter. It saves the inverter in case of voltage fluctuations and short circuits. It uses SPD and fuses to protect the panels and the inverter.

7. AJB Box

The Array Junction Box (AJB) gathers electricity generated by the solar system from multiple wires and sends it to the inverter. It uses blocking diodes to save the panels from reverse current flow.

8. Lightning Arrester

As per a report in The New Indian Express, lightning strikes in India rose from 1.38 crore in 2019-20 to 2 crore in 2022-23. A lightning arrester protects the panels from the impact of lightning. If lightning strikes the arrester, the lightning arrestor sends the power to the earth through an earthing rod, buried within the ground.

9. Other Components

You will need some other components such as conduit pipes, MC4 connectors, and wires while installing a solar system. MC4 connectors are used for connecting solar panels and wires are needed for electrical transmission.

You can compare quotations offered by vendors around you on our platform. The vendors follow all the government guidelines and will ensure a hassle-free installation process.

1 kW solar system price depends on factors such as solar installation charge, component price and the type of solar panels you have installed. You can check our blog to learn about the best solar panels in India

A 1 kW solar system is best for those on a tight budget and with minimal power requirements. It can power a load of up to 800 W. In case your monthly power requirement exceeds 150 units of electricity, you may also have to import from the DISCOM’s grid. In such a scenario, you can also consider upgrading to a 3 kW or 5 kW solar system.

FAQs

DCR stands for ‘Domestic Content Requirement’. If a panel is DCR-certified, its solar cells are manufactured and sourced from India. DCR certification of a panel is necessary for availing the PM Surya Ghar subsidy.

A 1 kW solar system with DCR panels can cost between Rs. 90,000 to Rs.1,30,000. The cost depends on the cost of the equipment such as ACDB and DCDB boxes, inverter, and the mounting structure.

The main eligibility criteria for getting PM Surya Ghar subsidy are as follows:

  1. Using DCR-certified and ALMM-listed solar panels
  2. Installation of an on-grid solar system by a DISCOM-empanelled vendor
  3. DISCOM must be empanelled with the MNRE

No, a 1 kW off-grid solar system must not be used to power an AC. A 1 kW off-grid solar system can handle a load of up to 800 W, whereas a 1 ton AC has a load of 1200 W at least. You can run the AC in 1 kW on-grid or hybrid solar system.

Main components of a 1 kW solar system are a net meter, inverter, ACDB DCDB, AJB box, lightning arrester, and mounting structure.

Mono PERC half cut, mono PERC half cut bifacial and TOPCon are the main types of solar panels available in the market.

For a 1 kW system, the cost of mono-PERC half-cut non-DCR will be Rs. 22,000 to Rs. 24,000 and of DCR panels will be Rs. 25,000 to Rs. 27,000 respectively.

Solar panels in a 1 kW system occupy a space of 59.2 sq. feet. You have to add the area between the panels and the area occupied by other components to calculate the total area needed for a system.
