1 Kilowatt Solar Panel System Price in India with Subsidy
You must check the components of a solar system to determine its price. If you buy DCR-certified and ALMM-listed panels for a 1 kW solar system, you can get a subsidy of Rs. 30,000 under the PM Surya Ghar: Muft Bijli Yojana. The 1 kilowatt solar panel price varies across manufacturers. Mono-PERC half-cut panels are currently the most-purchased panels in the market.
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. Different types of technologies along with their prices are as follows:
2. DCR vs Non-DCR Solar Panels
1 kilowatt solar panel cost 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. A solar panel gets a DCR certification if all its components are made and produced in India. DCR stands for ‘Domestic Content Requirement’.
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 DCR-certified panels. Depending on whether a panel is DCR or non-DCR, here’s how much they cost:
Solar Panel Types | Average Price/Wp (Non-DCR) | Average Price/Wp (DCR) |
Polycrystalline (335 W) | Price: Rs. 9000 to Rs. 11000 Per Wp Price: Rs. 27 to Rs. 33 | Price: Rs. 10000 to Rs. 12000 Per Wp Price: Rs. 30 to Rs. 36 |
Mono-PERC (550 W) | Price: Rs. 10000 to Rs. 12000 Per Wp Price: Rs. 18 to Rs. 22 | Price: Rs. 12000 to Rs.14000 Per Wp Price: Rs. 22 to Rs. 25 |
Mono-PERC Half Cut (550 W) | Price: Rs. 15000 to Rs. 17000 Per Wp Price: Rs. 27 to Rs. 31 | Price: Rs. 17000 to Rs. 19000 Per Wp Price: Rs. 31 to Rs. 34 |

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 rooftop solar system depends on the panel’s technology. Here’s how efficiency varies with the technology:
Type of Solar Panel | Efficiency |
Polycrystalline | 13-17% |
Mono PERC | 20-21% |
TOPCon | 22-23% |
2. Inverter
The electricity generated by a solar panel is Direct Current (DC). A solar inverter converts this DC power into Alternating Current (AC). Once the inverter converts DC into AC, the solar system sends this power to the grid. The grid then uses the AC to meet the electricity demand of households connected with it.
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.
4. Net Meter
An on-grid home solar panel 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. A net meter is a bidirectional meter that measures the net consumption or export of electricity.
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
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.

Area Required For 1 kW Solar Panel
1 mono-PERC half-cut panel has a capacity of 550 W. Thus, for 1 kW, you will need 2 panels.
A solar panel of 550 W usually has a length of 2.3 m and a width of 1.2 m.
Area of 1 panel = 2.3 x 1.2 sq. metres = 2.76 sq. metres
As we need 2 panels, the area required for a 1 kW solar system is 2.76 x 2 sq. metres = 5.52 sq. metres.
Apart from the area occupied by the panels, you must account for the space between the panels. A solar system of 1 kW could have a distance of 0.3 m between the panels.
Therefore, the area occupied by the solar panels of 1 kW is around 5.5 sq. metres.
Monthly Electricity Generated by a 1 kW 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 an example of how much electricity a 1 kW system can generate daily across months.
Month | Units Generated Per Day |
January | 4.2 |
February | 4.9 |
March | 5.6 |
April | 6.3 |
May | 6.8 |
June | 5.4 |
July | 5.1 |
August | 5 |
September | 4.9 |
October | 4.7 |
November | 4.6 |
December | 4.2 |
Monthly Savings Generated by a 1 kW System
We have already shown that a 1 kW system can monthly generate 120 to 180 units of electricity. You can multiply your electricity charges with the monthly solar electricity generation to calculate your savings.
If you have to pay Rs.8 for every unit of electricity you consume, the monthly savings will be Rs. Rs. 960 to Rs. 1440.
1 kW Solar System Subsidy in India
You can get a subsidy of Rs. 30,000 for installing a solar system of 1 kW under the PM Surya Ghar: Muft Bijli Yojana. To be eligible, you must install solar panels which are DCR-certified and listed in ALMM. We have already explained the meaning of DCR. Now let’s look at the meaning of ALMM.
ALMM stands for ‘Approved List of Models and Manufacturers’. It is a list of models approved by Ministry of New and Renewable Energy (MNRE) for government schemes such as PM Surya Ghar.
