Why the Cost of a 1kW Solar System in India Matters

Rooftop solar has moved from a niche hobby to a mainstream solution for Indian households. With electricity tariffs rising each year and the government promising up to 300 kWh of free electricity per month for eligible families, the financial calculus of installing a small 1 kW system has become a decisive factor for many buyers. Understanding the true cost 1kw solar system india after central subsidy helps homeowners decide whether the investment will pay for itself, how long the payback period will be, and what cash out‑flow is needed at the time of installation.

The price picture before subsidy

Before any government support, a typical 1 kW rooftop solar kit (including panels, inverter, mounting structure and wiring) costs between ₹70,000 and ₹85,000. Prices vary due to brand, panel efficiency, and local labour rates, but the range gives a realistic baseline for most Indian cities. This amount is often compared with the monthly electricity bill, which for a 1 kW system can offset roughly ₹500–₹800 of the average household’s consumption, depending on the state’s tariff.

Central subsidy under PM Surya Ghar Muft Bijli Yojana

The central government’s PM Surya Ghar Muft Bijli Yojana offers a flat ₹30,000 per kW for the first 2 kW of capacity. For systems between 2 kW and 3 kW, an additional ₹18,000 per kW is available, but the total subsidy is capped at ₹78,000 for any system of 3 kW or larger. Since we are focusing on a 1 kW system, the applicable subsidy is simply ₹30,000.

Item	Amount (₹)
Typical market price (1 kW)	70,000 – 85,000
Central subsidy (PM Surya Ghar)	30,000
Net cost after central subsidy	40,000 – 55,000
Possible state top‑up (varies)	See local DISCOM
Estimated monthly savings (₹)	500 – 800
Approx. payback period (years)	5 – 9

The net cost after central subsidy is the amount most homeowners actually need to arrange, either as cash or through a financing plan.

Why the net cost still feels high for many

Even after deducting the ₹30,000 central assistance, a household must still find ₹40,000‑₹55,000 to complete the installation. Several factors keep this figure from shrinking further:

Installation labour – Skilled electricians and roof‑mounting crews command higher wages in urban centres.
Quality of components – Panels with higher efficiency (e.g., 20 %+) cost more, but they generate more electricity per square metre, which can reduce the roof area needed.
Regulatory compliance – Net‑metering agreements, permits, and inspection fees add modest but unavoidable expenses.
State‑level top‑ups – While many states provide additional subsidies, the amounts differ widely, and the process can be bureaucratic. Homeowners are advised to check their state DISCOM or the official portal for the latest figures.

The opportunity: free electricity for a crore households

The scheme’s ambition is to provide up to 300 kWh of free electricity per month to 1 crore Indian households. For a typical 1 kW rooftop system, the annual generation is about 1,400 kWh (assuming 4 peak sun hours per day). This translates to a monthly average of ≈ 117 kWh. While a single 1 kW system does not reach the 300 kWh ceiling, it still offsets a substantial portion of a family’s consumption, especially in lower‑income homes that use less electricity overall.

The application flow – simple but essential

To claim the subsidy, homeowners must follow a clear online process:

Register on the national portal pmsuryaghar.gov.in using a valid Aadhaar and electricity bill.
Upload roof‑ownership proof and a recent DISCOM bill.
Obtain feasibility approval from the local DISCOM after they verify roof suitability.
Hire a registered vendor (installer) to carry out the installation.
Complete net‑metering registration with the DISCOM.
Pass inspection and submit the final report.
Receive subsidy directly into the bank account linked to the portal.

The net‑metering agreement is a prerequisite for subsidy release; without it, the central assistance will not be credited.

Bottom line for the average homeowner

Initial outlay: ₹70,000‑₹85,000 (market price)
Central subsidy: –₹30,000 (PM Surya Ghar Muft Bijli Yojana)
Net cash needed: ₹40,000‑₹55,000 (plus any state top‑up)
Monthly savings: ₹500‑₹800
Payback: roughly 5‑9 years, after which the electricity is essentially free.

Understanding these numbers helps families decide whether a 1 kW system fits their budget and long‑term energy goals. The next sections will debunk common myths and explore real‑world scenarios where a small rooftop system makes a difference.

Common Misconceptions

Myth 1 – “Solar is only for the rich”

Reality: The central subsidy of ₹30,000 per kW dramatically lowers the entry barrier. After the subsidy, a 1 kW system costs ₹40,000‑₹55,000, which many middle‑income families can finance through a small loan or a modest savings plan. Moreover, the monthly electricity savings of ₹500‑₹800 quickly accumulate, turning the system into a self‑paying asset over 5‑9 years. State‑level top‑ups, where available, further reduce the cash burden.

Myth 2 – “I can’t get subsidy because I already have a power connection”

Reality: The scheme targets households with an existing grid connection—that is, the very owners who receive regular electricity bills. As long as the home has a valid electricity connection, roof ownership, and has not previously claimed a solar subsidy, the applicant is eligible. The online portal pmsuryaghar.gov.in guides users through eligibility checks before any paperwork is submitted.

Myth 3 – “Solar panels need a lot of roof space, so I can’t install a 1 kW system”

Reality: Modern poly‑crystalline or mono‑PERC panels generate about 180‑200 W per panel. A 1 kW system therefore requires roughly 5‑6 panels, occupying ≈ 8‑10 sq m of roof area. Most Indian homes have enough space on a terrace, balcony, or sloping roof. If the roof is partially shaded, a slightly higher‑efficiency panel can be chosen, keeping the area requirement similar.

Myth 4 – “The subsidy process is too complicated and takes years”

Reality: While the process involves several steps, it is designed to be completed online. After registration on pmsuryaghar.gov.in, the DISCOM conducts a feasibility check, which usually takes a few weeks. Once the installer finishes the work and the net‑metering agreement is signed, the inspection and subsidy credit are processed within a few more weeks. The total timeline is typically 2‑3 months, not years.

Myth 5 – “Solar panels stop working after a few years”

Reality: Solar modules carry a 25‑year performance warranty and generally retain ≈ 80 % of their original capacity after that period. Inverters, the only component with a shorter life, usually have a 5‑10 year warranty and are easy to replace. Regular cleaning and a brief annual inspection are sufficient to keep the system running efficiently for decades.

Myth 6 – “I can’t sell excess electricity back to the grid”

Reality: Net‑metering agreements allow homeowners to feed surplus power into the grid and receive a credit on their electricity bill. The credit is typically at the same tariff as consumption, meaning every kilowatt‑hour generated either offsets your own usage or is monetised through the utility’s billing cycle.

Myth 7 – “All states give the same subsidy amount”

Reality: The central subsidy is uniform across India, but state‑level top‑ups differ widely. Some states may add a few thousand rupees per kW, while others may not offer any additional support. Homeowners should consult their local DISCOM or visit the official portal for the latest state‑specific information.

Myth 8 – “I need a big loan to afford solar”

Reality: Because the net cost after subsidy is modest, many banks and NBFCs provide short‑term loans with low interest rates specifically for rooftop solar. In many cases, the monthly loan instalment is less than the expected electricity savings, making the loan effectively self‑sustaining from day one.

By clearing these myths, homeowners can approach the decision with a realistic view of costs, benefits, and the practical steps needed to go solar.

Cost 1kW Solar System India — how it works / what you must know

Understanding the cost 1kw solar system india requires a look at three layers: the hardware price, the central cash subsidy, and any state‑level top‑ups. Below we unpack each layer, show you the step‑by‑step process to claim the subsidy, and provide a clear data table to help you estimate your out‑of‑pocket expense.

1. Hardware Cost Basics

A 1 kW residential solar kit typically includes:

Solar panels (monocrystalline or polycrystalline) – 4–5 panels, each ~200 W.
String inverter (≈ 1 kW) or micro‑inverters.
Mounting structure (roof‑type, powder‑coated aluminium).
Wiring, connectors, and safety devices (DC‑DC fuses, AC disconnect).
Installation labour (site survey, mounting, wiring, commissioning).

In 2026 the market price for a complete 1 kW kit ranges from Rs 70,000 to Rs 1,20,000, depending on panel efficiency, brand, and installer margin. Prices have been falling steadily due to higher domestic panel capacity and GST reductions on solar equipment.

2. Central Cash Subsidy – PM Surya Ghar Muft Bijli Yojana

The central government provides a cash‑in‑hand subsidy directly to the homeowner’s bank account after installation and verification. The subsidy is Rs 30,000 per kW for the first two kilowatts. For capacities between 2 kW and 3 kW, an extra Rs 18,000 per kW is added, capping the total at Rs 78,000 for systems of 3 kW and above. Since we focus on a 1 kW system, the applicable amount is Rs 30,000.

How the subsidy is paid

Register on the portal pmsuryaghar.gov.in with your Aadhaar, electricity bill, and roof ownership proof.
DISCOM feasibility – the local distribution company verifies roof suitability and net‑metering capacity.
Install the system through a registered vendor (installer must be listed on the portal).
Net‑metering agreement – sign the agreement with the DISCOM before the final inspection.
Inspection & certification – a government‑approved auditor checks the installation.
Credit – the subsidy amount is transferred to the bank account linked to your Aadhaar.

3. State Top‑Ups (Variable)

While the central cash amount is fixed, many states announce additional subsidies or interest‑free loans. The exact figures differ by state and are often linked to the local DISCOM’s solar policy. Homeowners should visit their state DISCOM website or the central portal for the latest numbers. Do not rely on a single figure here, as the amount can change annually.

4. Net Metering – The Savings Engine

Net metering allows you to export excess solar generation to the grid and receive a credit on your electricity bill. The credit is usually at the same tariff as consumption, making the effective electricity cost zero for the exported portion. The PM Surya Ghar Muft Bijli Yojana requires a net‑metering agreement before the subsidy is released, so ensure the DISCOM provides this service in your area.

5. Eligibility Checklist

Requirement	Details
Residence type	Indian household with a valid electricity connection
Roof ownership	Proof of ownership or long‑term lease
No prior subsidy	Must not have received any solar cash benefit earlier
System size	1 kW to 3 kW for residential eligibility
DISCOM verification	Feasibility and net‑metering agreement needed
Installation vendor	Must be registered on pmsuryaghar.gov.in

6. Step‑by‑Step Application Flow

Create account on pmsuryaghar.gov.in (Aadhaar, mobile OTP).
Enter project details – roof area, desired capacity (1 kW), preferred installer.
Upload documents – electricity bill, ownership proof, identity proof.
DISCOM review – they issue a feasibility report and net‑metering capacity.
Select installer – choose a vendor from the portal’s list; confirm quotation.
Installation & commissioning – vendor completes the work, provides a completion report.
Inspection – appointed auditor validates the system.
Subsidy credit – Rs 30,000 is transferred to your bank account.

Note: SolarSwytch offers an all‑in‑one operating system that helps installers generate subsidy‑aware proposals and track installations, making the above steps smoother for both parties.

Cost 1kW Solar System India — costs, savings and returns

Now that the subsidy mechanism is clear, let’s translate the numbers into a realistic out‑of‑pocket cost, expected annual savings, and the payback period for a typical Indian household.

1. Price Breakdown After Subsidy

The hardware and installation cost for a 1 kW system in 2026 lies between Rs 70,000 and Rs 1,20,000. Subtracting the central cash subsidy of Rs 30,000 gives the following net cost range:

Hardware + Installation (₹)	Central Subsidy (₹)	Net Cost After Subsidy (₹)
70,000	30,000	40,000
90,000	30,000	60,000
1,20,000	30,000	90,000

If your state offers an additional top‑up, the net cost will be lower. For illustration, a Rs 10,000 state top‑up would reduce the net cost to ₹30,000–₹80,000.

2. Annual Energy Production

A 1 kW rooftop system in most Indian cities generates roughly 1,300–1,500 kWh per year (average of 4–4.5 kWh/kW/day). This figure varies with location, shading, and orientation.

3. Savings on Electricity Bill

Assuming an average residential tariff of ₹7 per kWh, the annual monetary saving is:

Low estimate: 1,300 kWh × ₹7 = ₹9,100
High estimate: 1,500 kWh × ₹7 = ₹10,500

If net‑metering credits are at the same tariff, the entire generated electricity offsets your bill, effectively making the electricity cost zero for the solar share.

4. Payback Period

Payback period = Net Cost ÷ Annual Savings.

Net Cost (₹)	Low Savings (₹9,100)	High Savings (₹10,500)
40,000	4.4 years	3.8 years
60,000	6.6 years	5.7 years
90,000	9.9 years	8.6 years

With a state top‑up, the payback can shrink by 1–2 years.

5. Return on Investment (ROI) Over 25 Years

Solar panels are typically warranted for 25 years. Using the high‑end savings (₹10,500) and a net cost of ₹60,000:

Total savings = 25 × ₹10,500 = ₹2,62,500
ROI = (Total Savings – Net Cost) / Net Cost × 100 = (₹2,62,500 – ₹60,000) / ₹60,000 × 100 ≈ 337 %

Even at the higher cost bracket, the ROI remains well above 200 %, making rooftop solar a financially sound investment.

6. Sensitivity to Tariff Changes

If electricity tariffs rise by 5 % annually (a common trend), the annual savings increase accordingly, shortening the payback period. Conversely, a drop in tariffs would lengthen it, but the subsidy cushion still ensures a positive return.

7. Financing Options

Many banks and NBFCs now offer zero‑interest loans for solar installations, often tied to the subsidy disbursement schedule. Pairing a loan with the cash benefit can spread the net cost over 3–5 years, aligning repayments with the immediate electricity savings.

Use Cases and Scenarios

1. Small‑town family looking to cut monthly bills

Ramesh lives in a semi‑urban town in Maharashtra. His monthly electricity bill averages ₹2,200. After checking the cost 1kw solar system india, he finds that a 1 kW rooftop installation will cost ₹45,000 after the central subsidy. He applies on pmsuryaghar.gov.in, receives DISCOM approval within three weeks, and hires a local certified installer. Within two months the system is live, and his net‑metered bill drops to ₹1,400. The monthly saving of ₹800 means the loan (if taken) is repaid in about 6‑7 years, after which the electricity is essentially free.

2. Apartment owner with limited roof space

Neha owns a two‑bedroom flat in Bangalore. Her balcony can accommodate only 5 sq m of panels. She opts for high‑efficiency mono‑PERC modules that generate 200 W per panel, fitting five panels for a total of 1 kW. The system’s net cost after the central subsidy is ₹48,000. Because the balcony is shaded for a few hours each afternoon, the actual generation is about 1,200 kWh per year, still enough to offset roughly 30 % of her household consumption. Neha also enjoys the environmental benefit of reducing her carbon footprint by about 0.9 tCO₂ per year.

3. Rural homeowner aiming for energy independence

In a village in Uttar Pradesh, Suresh’s house is not connected to the grid permanently; he relies on intermittent supply. The government’s PM Surya Ghar Muft Bijli Yojana allows him to install a 1 kW system, receive the ₹30,000 subsidy, and then connect to the nearest DISCOM for net‑metering. After installation, he uses solar power during daylight hours and draws from the grid only at night, cutting his diesel generator usage by 80 %. The reduced fuel cost and the subsidy together make the project financially viable even without a full‑time grid connection.

4. Small business owner seeking to meet corporate sustainability goals

Arun runs a boutique textile shop in Delhi. He wants to showcase his commitment to green practices. By installing a 1 kW system on his shop’s rooftop, he reduces his electricity bill by ₹600 per month and can claim the renewable energy usage in his marketing material. The net cost after subsidy is ₹42,000, and because his business already has a bank line for equipment purchases, the expense is covered in a single payment. The visible solar panels also attract eco‑conscious customers, adding a modest boost to sales.

5. Homeowner in a high‑tariff state leveraging state top‑up

Priya lives in Kerala, where the per‑unit electricity tariff is among the highest in the country. While the central subsidy remains ₹30,000 per kW, Kerala’s DISCOM offers an additional state top‑up (exact amount varies). After checking the latest figures on her state DISCOM portal, Priya discovers she can receive an extra ₹10,000 for a 1 kW system. Her net out‑of‑pocket cost falls to ₹35,000. With monthly savings of ₹750, her payback period shrinks to about 4.5 years, making the investment especially attractive in a high‑tariff environment.

6. Apartment complex with collective installation

A housing society in Pune decides to install a common 10 kW solar plant on the rooftop of the building. The total central subsidy for the first 2 kW is ₹60,000, and for the remaining 8 kW the additional ₹18,000 per kW is applicable, but the overall cap of ₹78,000 is reached. After the subsidy, the society’s net cost is roughly ₹4,20,000. Dividing this among 20 families gives each a share of ₹21,000. Each household can then claim a proportionate share of the generated electricity, reducing their individual bills by ₹400‑₹500 per month.

7. Comparison with other Indian cities

When evaluating the cost 1kw solar system india, it helps to look at city‑specific data. For instance, the cost structure in Coimbatore includes slightly lower labour rates, while Jaipur’s panel market is highly competitive. You can explore those nuances in our regional guides:

8. Role of software platforms for installers

While the homeowner’s focus is on hardware costs and subsidies, the installation process is streamlined by specialized software tools. Platforms designed for Indian solar installers, such as the operating system offered by SolarSwytch, help generate subsidy‑aware proposals, manage leads over WhatsApp, and track each step from registration on pmsuryaghar.gov.in to final inspection. By reducing administrative errors, such tools indirectly lower the overall cost for the consumer, ensuring the quoted price reflects the true net amount after all applicable subsidies.

These scenarios illustrate that the cost 1kw solar system india is not a one‑size‑fits‑all figure. It varies with location, roof type, state top‑ups, and the homeowner’s consumption pattern. By understanding the subsidy structure, the application process, and the real‑world savings, Indian families can make an informed decision that aligns with their financial goals and sustainability aspirations.

Cost 1kw Solar System India – Step‑by‑Step Roadmap

Check Eligibility – Make sure you own the roof, have a valid electricity connection, and have not received any earlier solar subsidy. The scheme applies only to residential, grid‑connected rooftop systems.
Visit the Official Portal – Go to pmsuryaghar.gov.in and create an account using your Aadhaar and electricity bill details.
Enter System Size – For a 1 kW system, the portal will automatically calculate the central subsidy of ₹30,000 (the first kW under the PM Surya Ghar Muft Bijli Yojana).
State Top‑Up Check – After the central amount is shown, the portal will display any additional state‑level top‑up, if applicable. Since state amounts vary, you should confirm the exact figure on your state DISCOM’s website or the portal itself.
Upload Documents – Required documents include:
- Proof of roof ownership (sale deed or rent agreement)
- Latest electricity bill
- Identity proof (Aadhaar, PAN)
- No‑objection certificate from the building society (if applicable)
DISCOM Feasibility Review – Your application is forwarded to the local DISCOM. They will verify roof suitability, load‑profile, and net‑metering feasibility. This step may involve a site visit by a DISCOM engineer.
Obtain Net‑Metering Agreement – Before any installation, you must sign a net‑metering contract with the DISCOM. The agreement outlines how excess generation will be credited to your bill.
Select a Registered Installer – Choose a solar installer who is registered on the portal. The installer will generate a quotation that includes the central subsidy amount.
Generate Proposal Using Installer Software – Modern installers often use platforms like SolarSwytch to create subsidy‑aware proposals, manage leads over WhatsApp, and track the installation end‑to‑end. This simplifies paperwork for you.
Finalize the Quote – The installer’s quotation will show the gross cost of a 1 kW system (including panels, inverter, mounting, wiring, and labour) and then subtract the ₹30,000 central subsidy.
Pay the Balance – After the subsidy is deducted, you pay the remaining amount directly to the installer. Typical balance amounts range from ₹20,000 to ₹35,000 depending on hardware choices and local labour rates.
Installation – The installer mounts the panels, connects the inverter, and links the system to the DISCOM’s net‑metering point. All work must follow the Indian Electricity Rules and local building codes.
Inspection & Commissioning – Once installed, the DISCOM conducts a final inspection to verify compliance with the net‑metering agreement.
Subsidy Disbursement – After a successful inspection, the central subsidy of ₹30,000 is transferred directly to the bank account you provided during registration.
Activate Net‑Metering – The DISCOM activates your net‑metering meter. From this day forward, any surplus electricity you generate is credited to your electricity bill.
Monitor Savings – Track your monthly electricity bill to see the impact. A 1 kW system typically generates 4–5 kWh per day in most Indian cities, translating to a reduction of roughly ₹500–₹800 per month in electricity charges.
Maintenance – Panels require minimal upkeep—clean them twice a year and ensure the inverter’s firmware is up‑to‑date. Most installers offer a 5‑year performance guarantee on panels and a 2‑year warranty on inverters.
Future Expansion – If you later decide to increase capacity to 2 kW, the central subsidy for the second kW is also ₹30,000. For the third kW, the central subsidy rises to ₹48,000 (₹30,000 + ₹18,000) but the total central cap remains ₹78,000.

Following these steps ensures you receive the full ₹30,000 central subsidy for a 1 kW rooftop system and helps you avoid common pitfalls such as missing the DISCOM net‑metering agreement or submitting incomplete documents.

Illustrative Example

Scenario: A family in Jaipur wants to install a 1 kW rooftop solar system in March 2026. They have a clean, south‑facing roof, a valid electricity connection, and no prior solar subsidy.

Eligibility Confirmation – The family checks the eligibility checklist and finds they meet all criteria: roof ownership, active electricity bill, and no earlier subsidy.
Portal Registration – They log onto pmsuryaghar.gov.in, create a user profile, and select “Residential Rooftop Solar” as the scheme.
System Size Entry – They input “1 kW” as the desired capacity. The portal instantly shows a central subsidy of ₹30,000 for the first kilowatt.
State Top‑Up Inquiry – The portal indicates a state‑level top‑up may be available. The family visits the Rajasthan DISCOM website to confirm the exact amount (they note it could add up to a few thousand rupees).
Document Upload – They upload:
- Property deed confirming roof ownership
- Latest electricity bill (₹2,200)
- Aadhaar card and PAN
- No‑objection certificate from the housing society (if required)
DISCOM Feasibility – The Rajasthan DISCOM receives the application, schedules a site visit, and validates that net‑metering is feasible on the location. The engineer signs off, and the portal updates the status to “Feasibility Approved.”
Net‑Metering Contract – The family signs a net‑metering agreement with the DISCOM, agreeing that excess generation will be credited at the prevailing tariff.
Selecting an Installer – Using the portal’s list of registered vendors, they choose SolarTech Jaipur, a certified installer with good reviews. SolarTech uses a software platform (similar to SolarSwytch) to generate a subsidy‑aware quotation.
Quotation Details – The quote breaks down as follows:

Item	Cost (INR)
Solar Panels (10 pcs, 100 W each)	18,000
String Inverter (1 kW)	7,000
Mounting Structure & Wiring	5,000
Labour & Installation	4,000
Gross Total	34,000
Central Subsidy (₹30,000)	‑30,000
Net Payable	4,000

Balance Payment – The family pays ₹4,000 to SolarTech. They receive a receipt and a copy of the net‑metering agreement.
Installation Day – SolarTech’s crew installs the panels, connects the inverter, and links the system to the DISCOM’s net‑metering point. The installation takes a single day.
Inspection – The DISCOM inspector verifies the wiring, inverter settings, and safety compliance. After a successful check, the inspector marks the installation as “Commissioned.”
Subsidy Credit – Within two weeks, the central subsidy of ₹30,000 is transferred to the family’s bank account, as per the details provided during portal registration.
First Month’s Generation – In April 2026, the system generates 120 kWh (≈4 kWh per day). The DISCOM credits the excess 20 kWh (after meeting the family’s consumption) to the next month’s bill. The family’s electricity bill drops from ₹2,200 to ₹1,500, saving ₹700.
Annual Savings Estimate – Assuming an average of 4.5 kWh/day, the system produces about 1,642 kWh per year. At a tariff of ₹7/kWh, the annual savings are roughly ₹11,500. Subtracting the net payable of ₹4,000, the payback period is under 1 year.

Key Take‑aways from the Example

The central subsidy of ₹30,000 covers the majority of the hardware cost for a 1 kW system.
State top‑ups can further reduce the net amount, but they vary; always verify on the state DISCOM portal.
Using a registered installer who leverages a solar‑installer OS streamlines the proposal, paperwork, and tracking.
Net‑metering is essential for receiving credit for excess generation and for subsidy eligibility.

Why the Subsidised 1 kW Rooftop Option Stands Out

Largest Direct Cash Benefit – The central subsidy of ₹30,000 dramatically lowers the net cost, making it the most affordable clean‑energy investment for a typical Indian home.
Net‑Metering Revenue – Unlike a water heater or LED upgrade, a solar PV system can feed excess power back to the grid, earning credits that further reduce the electricity bill.
Long‑Term Asset – Solar panels have a 25‑year performance guarantee, turning the modest upfront expense into a lasting asset that can increase property value.
Scalability – Homeowners can start with 1 kW and later expand to 2 kW or 3 kW, receiving additional central subsidies of ₹30,000 for the second kilowatt and ₹48,000 for the third, capped at ₹78,000 total.

When Might an Alternative Be Better?

Frequent Power Outages – If grid reliability is a major concern, a battery‑backed system provides backup, though it comes at a higher cost and currently receives no central subsidy.
Limited Roof Space – For apartments or homes with shaded roofs, a solar water heater or LED retrofit may be more feasible.
Very Low Budget – LED retrofits can be done for a few thousand rupees and still deliver noticeable bill reductions without any paperwork.

Decision‑Making Checklist

Do you have an unobstructed roof of at least 8 m²?
Is your DISCOM offering net‑metering in your area? (Check the local DISCOM website.)
Can you allocate ₹4,000‑₹15,000 for the net payable after subsidy?
Do you prefer a long‑term asset that also adds resale value?

If the answers are “yes,” the subsidised 1 kW rooftop solar system remains the most cost‑effective path. For detailed city‑specific numbers, explore our other posts such as Solar in Coimbatore 2026: Cost, Subsidy, Installers & Savings.

All figures are based on the central subsidy guidelines released by the Government of India and reflect typical market prices as of March 2026.

Cost 1kW Solar System India — rules, compliance and regulations

Installing a rooftop solar system under the PM Surya Ghar Muft Bijli Yojana involves several regulatory steps. Compliance ensures you receive the cash subsidy, can sell excess power via net metering, and avoid penalties.

1. Eligibility Confirmation

Residential status: Only private households with a valid electricity connection qualify.
Roof ownership: Proof of ownership or a lease agreement of at least 5 years is mandatory.
No prior subsidy: The scheme is a one‑time benefit per household; any earlier claim disqualifies you.

2. Registration on the Central Portal

All applications must be lodged on pmsuryaghar.gov.in. The portal captures:

Applicant details (Aadhaar, PAN, mobile number)
Property address and electricity bill
Desired system size (1 kW in this guide)

After submission, the portal generates a Reference ID used throughout the process.

3. DISCOM Feasibility and Net‑Metering Agreement

The local distribution company (DISCOM) reviews the roof layout, shading, and grid capacity. They issue:

Feasibility report confirming that a 1 kW system can be connected safely.
Net‑metering agreement – a legal contract that defines the export‑import tariff, metering equipment, and billing adjustments.

Only after this agreement is signed can the installation proceed and the subsidy be released.

4. Installer Registration

The solar installer must be registered on the central portal. This ensures they are vetted and can submit the post‑installation report. Installers often use software platforms like SolarSwytch to generate subsidy‑aware proposals and track the workflow, replacing manual spreadsheets.

5. Installation Standards

Electrical safety: Compliance with IS 1293 (solar PV modules) and IS 12958 (inverters) standards.
Structural safety: Mounting structures must meet IS 456 for load‑bearing capacity.
Grid code: The inverter must have anti‑islanding protection as per the local DISCOM’s grid code.

6. Inspection and Certification

A government‑approved auditor conducts a final inspection covering:

Correct wiring and earthing
Inverter settings and synchronization with the grid
Proper labeling and signage

The auditor uploads a completion certificate to the portal, triggering the subsidy release.

7. Subsidy Disbursement Timeline

While the exact processing time varies by state, the central guideline states that the subsidy amount is credited within 30 days of the auditor’s approval, provided all documents are in order.

8. Post‑Installation Obligations

Maintain net‑metering meter: The DISCOM may periodically verify the meter’s accuracy.
Annual performance report: Some states ask for a yearly generation statement for continued eligibility for any future top‑ups.
Warranty claims: Keep all vendor warranties; the installer remains responsible for any post‑installation defects during the warranty period.

9. Penalties for Non‑Compliance

Installing without a net‑metering agreement can lead to disconnection and loss of subsidy.
Misrepresenting roof ownership or prior subsidy receipt may result in legal action and repayment of the cash benefit.

By following these compliance steps, Indian homeowners can smoothly navigate the subsidy process, secure the cash benefit, and enjoy a hassle‑free solar experience.

Frequently Asked Questions

1. What is the exact out‑of‑pocket cost for a 1 kW solar system after the central subsidy?

After the ₹30,000 per kW central subsidy, the typical homeowner pays between ₹12,000 – ₹18,000. The range covers GST, installation labour, and any minor variations in kit price across suppliers.

2. Does the PM Surya Ghar Muft Bijli Yojana cover the cost of the inverter?

Yes. The central subsidy is applied to the whole 1 kW system, which includes panels, inverter, mounting structure, wiring, and installation. The inverter’s share is covered proportionally.

3. Can I claim the subsidy if I already have a small solar kit installed?

No. The scheme is only for first‑time residential rooftop installations. If you have previously received any solar subsidy, you are ineligible for the central benefit.

4. How long does it take to receive the subsidy money after installation?

The timeline depends on the DISCOM’s processing speed. Generally, once the inspection report is uploaded and the net‑metering agreement is signed, the subsidy is credited within 30‑45 days.

5. Do I need to pay any application fee to the portal?

The national portal pmsuryaghar.gov.in does not charge a fee for registration or subsidy application. Any processing fees, if levied, are state‑specific and must be verified with your local DISCOM.

6. Is a net‑metering agreement mandatory for the subsidy?

Yes. The scheme requires a valid net‑metering contract with the local DISCOM before the subsidy can be disbursed. It ensures that excess electricity generated is accounted for and credited.

7. What documents are required for the subsidy application?

You will need: proof of identity (Aadhaar), electricity bill (latest), ownership or lease proof of the roof, PAN card, and bank account details for credit transfer. The installer may also need to submit the system layout and inverter certificate.

8. Can I install the system myself and still get the subsidy?

The installer must be a vendor registered on the PM‑SGMBJ portal. DIY installation is not allowed for subsidy eligibility because the system must be inspected and certified by a registered professional.

9. How is GST calculated on the solar kit?

GST is levied at 5 % on solar panels and 18 % on inverters, mounting structures, and installation services. The total GST amount is added to the invoice before the subsidy is applied.

10. Are there any limits on the number of households that can claim the subsidy?
