Home Solar Installation Cost in Detail With Pricing Factor

‘Solar system costs’ is one of the most asked question of those interested in solar plant installation. Home solar system costs depend on multiple factors such as the price of different components, installation charges and other charges.

You have to learn about all of those factors to determine the actual cost of your rooftop solar system.

Here, you will learn about the solar panel installation cost in detail. We will also discuss how the total solar power systems prices depend on those factors. This blog will clear your unsolved questions about ‘home solar installation cost’.

The capacity of your solar power system is the first factor that determines the home solar power system cost. Follow this table to learn the prices of solar systems based on power capacity:

Factors Affect Home Solar Panel Installation Cost

A solar system consists of various components like panels, inverters, mounting structures, etc. The home solar installation cost depends on all these items as mentioned below:

1. Price of Solar Panels

 The solar power panel price varies according to 2 factors:

  • Technology 
  • Whether the panels are DCR-Certified

In the following table, you can find the prices of solar panels according to their type and whether they are DCR or non-DCR:

Solar Panel Types

Per Watt Price (Non-DCR)

Module Price (Non-DCR)

Per Watt Price (DCR)

Module Price (DCR)

Mono-PERC Half Cut (550 Wp)

Rs. 20/Watt

Rs.11,000 – Rs. 12,000

Rs. 23/Watt

Rs.12,500 – Rs. 13500

Mono-PERC Half Cut Bifacial (550 Wp)

Rs. 22/Watt

Rs. 12,000 – Rs.13,000

Rs. 25/Watt

Rs. 14,000 – Rs. 15000

TOPCon Bifacial (N Type) (570 Wp)

Rs. 24/Watt

Rs.14,000 – Rs. 15,000

Rs. 27/Watt

Rs.15,500 – Rs. 16,000

It is always the best decision to choose solar panels from the top companies. If you want to know more about the top solar companies in India in detail along with their top products, you can read our blog on it.

2. Cost of Solar Inverter

On grid inverter

A solar system generates Direct Current (DC). However, home appliances run only on Alternating Current (AC). A solar inverter converts the DC into AC.

Here is a table mentioning the capacity-wise price of solar inverters:

Inverter Capacity Cost 
1 kW* Rs.13,500
2 kW Rs.17,000
3 kW Rs.21,000
5 kW Rs.29,000
10 kW Rs.48,000

*Note: Most of the top-quality manufacturers do not sell 1 kW solar inverters. So, even if you install a 1 kW solar plant, you may have to install a 2 kW or 3 kW solar inverter from a trusted brand.

If you want to know more about the top solar inverter brands in India, you can follow our other blog on it.

3. Cost of AC-DB DC-DB Boxes

ac db box

The AC Distribution Board (AC-DB) helps to distribute the electricity from a solar inverter to an AC load system via an energy meter. A DC Distribution Board (DC-DB) helps to link the output power of solar panels to the input of your solar inverter.

The cost of a 32AMP 320V Three Phase ACDB box is around Rs.3,200. On the other hand, the cost of a 3 IN 3 OUT DCDB box is approx Rs.3,700.

4. Cost of Mounting Structure

solar panel structure

The mounting structure or panel stand is another important solar installation accessory. But remember, this stand helps to support the solar panels for a lifetime. Any negligence in selecting or installing the mounting structure can lead to a huge loss in critical situations like storms or heavy rainfall.

In India, the standard cost of mounting structures with zinc aluminium magnesium steel channels is around Rs.8 per watt. Therefore, the cost of the mounting structure for rooftop solar plant is as follows:

Rooftop Solar Capacity Cost of Mounting Structure 
1 kW Rs.8,000
2 kW Rs.16,000
3 kW Rs.24,000
4 kW Rs.32,000
5 kW Rs.40,000
6 kW Rs.48,000
8 kW Rs.64,000
10 kW Rs.80,000

To learn about different varieties of mounting structures, you can read our blog on mounting structures for solar panels.

5. Solar Installation Charge

Your solar vendor takes an installation charge for their service. For the initial setup of your solar system, you have to pay around Rs.10,000 – Rs.30,000 as a solar panel installation charge to the vendor.

The installation charges can go up or down based on the complexity of your solar system’s structure.

6. Cost of AMC

Your solar system must be serviced regularly to ensure its performance and longevity. You can sign an annual maintenance contract (AMC) for regular evaluation of your solar system. To know more, you can check my page on Solar annual maintenance contract (AMC).

Opting for Solar AMC is unavoidable if you have a solar plant, especially if you have a commercial & industrial solar plant. We at Das Energie offer solar AMC services through our installation partners. Visit our solar AMC  page to learn more about it.

7. Cost of Other Components

cost of other solar components

The other components of a home solar system include wires, array junction boxes, lightning arrestors, earthing kits, and other solar installation accessories.

Solar wires are the medium to transfer electricity from solar panels to the inverter. You will have to buy two types of wire: DC wire, and AC wire. Lightning arrestors and earthing kits save your on-grid solar system from thunder or lightning.

The cost of all these components can be between Rs.15,000 – Rs.25,000 based on the selection.

We have separate blogs where we have discussed briefly the cost of solar systems based on their system capacity. There we have already discussed the factors, price chart and other details.

  • If you need a solar system with the lowest electricity generation, you can check the solar system for home cost of a 1 kW solar system.
  • To get details of solar panels for home cost (3 kW solar system), read our blog on 3 kW solar system price.
  • If you want a solar system that generates 600+ units/month, you can check out the 5 kW solar system cost.
  • For generating around 1200 to 1500 units of electricity per month, you need 10 kW system. Know the 10kw solar system price.

Other Factors Influencing Rooftop Home Solar System Cost

Here are the factors that influence the cost of home solar panel system:

1. Solar Panel Company

Solar panel prices vary across manufacturing companies. To explain in detail, here is a comparison of prices of non-DCR panels (540 to 550 W) of different companies.

Follow this table to understand the price difference:

Company Name Product Name Price
Waaree 540Wp 144 Cells Mono PERC Rs.15,500
Vikram Solar 540W Mono Perc Half Cut Solar Panel Rs.14,000
Adani Power 540Wp Half cut mono perc solar panel Rs.16,000
Loom Solar SHARK 550 Watt – Mono Perc Half Cut Rs.13,500

2. DCR vs non-DCR

DCR stands for Domestic Content Requirement. A panel is DCR-certified if its solar cells are sourced from and manufactured in India. On the other hand, non-DCR panels have solar cells of foreign origin.

DCR panels are expensive compared to non-DCR panels. For example, mono-PERC half cut DCR panels cost Rs.23/Watt and non-DCR panels cost Rs. 20/Watt.

However, you will be eligible for PM Surya Ghar subsidy only if you use DCR-certified panels.

3. Type of Solar Panels

Different type of solar panels

The panel type you choose to install on your rooftop is another main influencer of solar panel installation cost. If you choose Poly PERC solar panels, it will cost you around Rs.17 – 20 per watt. For Mono PERC panels, you have to pay Rs.20 – 24 per watt. If you want to install N-Type TOPCon panels, you have to pay Rs.23 – 28 per watt.

FAQs About Solar System for Home Price

The cost of a 1 kW solar system is between Rs.90,000 to Rs. 1,30,000. It depends on the components of your solar system such as solar panels, solar inverter, installation charges, and other components.

If you want to install a 5 kW solar system in India, you have to pay around Rs.2,90,000 to Rs.3,30,000.

The yearly maintenance cost of a rooftop solar system is approximately 1%-2% of your initial set-up cost. For a 3 kW solar panel, the cost ranges between Rs.1900-3800 per year.

Monthly, a 3 kW solar system can generate 360 to 540 units of electricity.

Some of the factors which affect the efficiency of a solar panel include the angle at which the sunlight falls on the panels, the temperature coefficient, and the type of panels used.

A solar system should last for 25 to 30 years. That’s why most solar panels have a performance warranty of 25-30 years.

    Non-DCR panels lead to a much lower cost in spite of the subsidy for DCR panels. So why should I buy DCR panels?
