The cost of solar panels depends on 2 main factors:
Here’s how these factors affect a solar panel’s cost:
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.

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 |

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

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.
