Ultimate Guide to Cost Solar Panels Delhi 2024

Rooftop solar is becoming a realistic option for Delhi households, especially after the central government’s PM Surya Ghar Muft Bijli Yojana lifted a big chunk of the upfront cost. Understanding the cost solar panels Delhi homeowners actually pay means looking beyond the sticker price of modules and inverters. You must factor in the per‑kilowatt central subsidy, any state‑level top‑up, the net‑metering arrangement with your local DISCOM, and the installation charges that a qualified vendor will quote. This article walks you through every piece of the puzzle, so you can calculate the net out‑of‑pocket expense and see how quickly the system pays for itself.

In Delhi, a typical residential rooftop system ranges from 1 kW to 5 kW, depending on roof space and electricity demand. The central subsidy is fixed at Rs 30,000 per kW for the first 2 kW and Rs 18,000 per kW for the next 1 kW (capped at Rs 78,000 for systems of 3 kW and above). Anything above 3 kW receives no additional central assistance, though many states may add a modest top‑up. Because the scheme applies only to grid‑connected residential installations, commercial users are excluded. The application process is entirely online via pmsuryaghar.gov.in, where you first register, obtain DISCOM feasibility approval, install through a registered vendor, complete net‑metering, and finally receive the subsidy directly into your bank account.

While the hardware cost has come down over the past few years, the real value for a Delhi homeowner lies in the free electricity entitlement of up to 300 kWh per month that the scheme promises. This translates into a substantial reduction of your monthly bill, often making the pay‑back period under five years. In the sections that follow we break down the numbers, explain the subsidy workflow, and show you how to use tools like SolarSwytch’s installer‑focused operating system to generate GST‑aware proposals and track the subsidy claim – all without ever touching a spreadsheet.

Quick Answer: After the central subsidy, a 3 kW residential system in Delhi typically costs between Rs 1.2 lakh and Rs 1.5 lakh out‑of‑pocket, plus installation and GST.

Understanding the Cost of Solar Panels in Delhi 2026

For homeowners in the National Capital Region, the monthly electricity bill has become a source of constant stress. As Delhi experiences hotter summers and a higher reliance on air conditioning, the cost of powering a modern household is skyrocketing. Many residents are now looking for a permanent solution to break free from the rising tariffs of the local DISCOMs. This is where rooftop solar enters the picture, transforming a monthly expense into a long-term investment.

However, the biggest hurdle for most families is the initial investment. When people search for the cost solar panels delhi, they are often overwhelmed by the variety of quotes they receive. One vendor might quote a high price for premium panels, while another offers a budget-friendly option that might lack long-term reliability. Without a clear understanding of how the pricing is structured and how the government subsidies work, many homeowners hesitate to make the switch.

The opportunity in 2026 is significant. With the PM Surya Ghar Muft Bijli Yojana, the Indian government has made solar energy accessible to the common man. The goal is to provide up to 300 units of free electricity per month to 1 crore households across the country. For a Delhi resident, this means that a correctly sized solar system can virtually eliminate the electricity bill, providing a hedge against future price hikes.

The “problem” isn’t just the price of the hardware; it is the complexity of the procurement process. A homeowner must navigate technical specifications, find a registered vendor, apply through the national portal, and coordinate with the DISCOM for net metering. Because this process involves multiple steps, there is often a gap in communication. This is why professional installers are increasingly using tools like SolarSwytch, an all-in-one operating system for solar installers in India, to provide more accurate, subsidy-aware proposals and track installations end-to-end.

When calculating the cost solar panels delhi, one must look beyond the sticker price. You have to consider the “Net Cost,” which is the Total Installation Cost minus the Central Financial Assistance (CFA). The central subsidy is structured to benefit smaller residential systems the most. For the first 2 kW, the subsidy is Rs 30,000 per kW. For systems between 2 kW and 3 kW, an additional Rs 18,000 per kW is provided. The total central subsidy is capped at Rs 78,000 for any system of 3 kW or above.

To help you visualize the financial impact, consider the following comparison between a traditional grid-dependent home and a solar-powered home in Delhi.

Feature	Grid-Dependent Home	Solar-Powered Home (3kW+)
Monthly Bill	High (increases with summer AC use)	Near Zero (up to 300 units free)
Upfront Cost	Zero	Moderate (Reduced by Subsidy)
Long-term Cost	Infinite (Bills forever)	Fixed (Pay once, use for 25 years)
Energy Source	Coal-based Grid Power	Clean, Renewable Sunlight
Property Value	Standard	Higher (Due to green infrastructure)
Government Support	None	Eligible for PM Surya Ghar subsidy

The transition to solar is no longer just an environmental choice; it is a financial strategy. In a city like Delhi, where sunlight is abundant for most of the year, the return on investment (ROI) is faster than in many other regions. The primary challenge remains the “entry barrier”—the initial cash outflow. However, when you factor in the capped subsidy of Rs 78,000 for larger systems, the payback period drops significantly.

Furthermore, the integration of net metering allows homeowners to send excess electricity back to the grid during the day and draw it back at night. This means your meter essentially works in your favour, offsetting the costs of nighttime usage. The real “cost” is actually the cost of not installing solar, as you continue to pay for expensive electricity every single month while your roof remains an unused asset.

By understanding the breakdown of the cost solar panels delhi, homeowners can move from a position of uncertainty to one of confidence. The key is to work with a registered vendor who can guide you through the pmsuryaghar.gov.in portal, ensure the DISCOM feasibility approval is obtained, and manage the net metering agreement so that the subsidy is credited directly to your bank account without delays.

Common Misconceptions

When researching the cost solar panels delhi, many homeowners encounter a wealth of misinformation. These myths often lead people to believe that solar is either too expensive or too complicated for their specific home. Let us debunk the most common misconceptions.

Myth 1: Solar panels are only affordable for the wealthy.

Reality: This was true a decade ago, but the landscape has changed entirely. With the introduction of the PM Surya Ghar Muft Bijli Yojana, the government is providing substantial financial support to residential households. By offering Rs 30,000 per kW for the first 2 kW and an additional Rs 18,000 per kW for the next 1 kW, the government has slashed the effective cost. When you combine these subsidies with the monthly savings on electricity bills, solar becomes a tool for middle-income families to save money, not just a luxury for the rich.

Myth 2: Solar doesn’t work during Delhi’s smoggy winters or rainy days.

Reality: While it is true that solar panels require sunlight to generate power, they do not require “perfect” cloudless skies. Modern photovoltaic (PV) cells are designed to capture a broad spectrum of light, including diffused light that penetrates through clouds or smog. While generation may dip slightly during a heavy monsoon week or a very foggy January morning, the annual average of sunlight in Delhi is more than sufficient to meet the target of 300 free units per month. Solar is a game of annual yields, not daily perfection.

Myth 3: Maintenance is expensive and requires constant cleaning.

Reality: Solar panels have no moving parts, which means there is very little that can “break.” The primary maintenance task is keeping the panels free of dust and bird droppings, which is especially important in Delhi’s dusty environment. This usually involves a simple water rinse every few weeks. Most reputable installers provide a comprehensive warranty on the panels (often 25 years) and the inverter. The operational cost is negligible compared to the massive savings on the monthly electricity bill.

Myth 4: You need a massive roof to make solar viable.

Reality: Many people believe they need a warehouse-sized roof to see any benefit. In reality, even a small 2 kW or 3 kW system can make a huge difference for a typical Delhi apartment or independent house. Because the PM Surya Ghar Muft Bijli Yojana specifically targets households with up to 300 units of consumption, the systems required are relatively compact. As long as you have a clear, shadow-free area on your roof and the legal right to use that space, you can significantly reduce your energy costs regardless of the total roof size.

Cost Solar Panels Delhi — how it works / what you must know

Understanding the cost solar panels Delhi involves three layers: technical sizing, financial incentives, and regulatory steps. Below we unpack each layer in detail.

1. Sizing your rooftop system

The first decision is the system size (kW). A typical Delhi home uses 150‑250 kWh per month. To meet up to 300 kWh free electricity, a 3‑kW system is sufficient for most families. Larger homes may opt for 4‑5 kW, but the central subsidy stops at 3 kW, so the extra capacity is fully out‑of‑pocket.

System Size (kW)	Approx. Daily Generation (kWh)	Monthly Generation (kWh)
1.5	5–6	150–180
2.5	8–9	240–270
3.0	10–11	300–330
4.0	13–14	390–420
5.0	16–17	480–510

Source: MNRE solar irradiance data (mnre.gov.in).

2. Calculating the central subsidy

The subsidy formula is straightforward:

First 2 kW: 2 kW × Rs 30,000 = Rs 60,000
Next 1 kW (if applicable): 1 kW × Rs 18,000 = Rs 18,000
Maximum central amount: Rs 78,000 for any system ≥ 3 kW

For a 2.5 kW system, the subsidy is Rs 60,000 + (0.5 kW × Rs 18,000) = Rs 69,000. For a 4 kW system, the subsidy remains capped at Rs 78,000.

3. State‑level top‑ups

Several states announce additional assistance, but amounts vary widely. The official guidance is to check your state DISCOM portal or the central portal for the latest figures. No specific numbers are quoted here to avoid misinformation.

4. The application workflow

Register on pmsuryaghar.gov.in with your Aadhaar, electricity bill, and roof ownership proof.
DISCOM feasibility – the local distribution company validates roof orientation, shading, and load.
Select a registered vendor – the installer must be approved under the scheme.
Installation & net‑metering – after site work, the system is connected to the grid and a net‑metering agreement is signed.
Inspection – a government officer verifies compliance.
Subsidy credit – the approved amount is transferred directly to your bank account.

5. Role of software platforms

While SolarSwytch does not sell hardware, its operating system helps installers generate subsidy‑aware proposals, calculate GST, and track the application status. Installers can share WhatsApp‑enabled quotations with homeowners, making the process transparent and faster.

6. Financial impact of free electricity

The scheme promises up to 300 kWh of free electricity per month. At the average Delhi tariff of Rs 8 per kWh, that equals a saving of Rs 2,400 per month or Rs 28,800 per year. Over a 25‑year system life, the cumulative saving can exceed Rs 7 lakh, far outweighing the initial out‑of‑pocket cost.

7. Common pitfalls

Missing DISCOM approval – without a feasibility letter, the subsidy is denied.
Using a non‑registered vendor – only approved installers can claim the subsidy.
Delaying net‑metering agreement – the subsidy is released only after net‑metering is active.
Applying for a second time – the scheme disallows households that have previously received any solar subsidy.

For more detailed guidelines, refer to the official portal’s FAQ section: PM Surya Ghar Muft Bijli Yojana – Official Site.

Cost Solar Panels Delhi — costs, savings and returns

Now that the subsidy and system sizing are clear, let’s translate them into actual numbers a Delhi homeowner will see on a quotation.

1. Hardware price range (2026)

Solar modules: Rs 35,000 – Rs 45,000 per kW (poly‑crystalline or mono‑PERC).
Inverter: Rs 12,000 – Rs 18,000 per kW.
Mounting & wiring: Rs 5,000 – Rs 8,000 per kW.
Installation & commissioning: Rs 8,000 – Rs 12,000 per kW (includes labor, permits, and testing).

2. GST and other charges

All hardware is subject to 18 % GST. Installation services also attract 18 % GST. No additional hidden fees are mandated by the central scheme.

3. Sample cost breakdown (3 kW system)

Item	Unit Cost (INR/kW)	Qty (kW)	Sub‑total (INR)
Solar modules	40,000	3	1,20,000
Inverter	15,000	3	45,000
Mounting & wiring	6,500	3	19,500
Installation & commissioning	10,000	3	30,000
Total before GST	—	—	2,14,500
GST @18 %	—	—	38,610
Grand Total	—	—	2,53,110

Central subsidy: Rs 78,000 (capped). Net out‑of‑pocket: Rs 1,75,110.

4. Pay‑back calculation

Annual electricity bill without solar: Approx. Rs 30,000 (250 kWh × Rs 8 × 12).
Free electricity from scheme: 300 kWh × Rs 8 × 12 = Rs 28,800 saved.
Remaining bill after free quota: Rs 1,200.
Annual net saving: Rs 28,800 – (GST on electricity not applicable) ≈ Rs 28,800.
Pay‑back period: Rs 1,75,110 ÷ Rs 28,800 ≈ 6.1 years.

If the homeowner consumes more than 300 kWh per month, the excess is billed at the regular rate, further improving the return.

5. Long‑term ROI

Solar panels typically degrade by 0.5 % per year. Over 25 years, the system will still generate around 87 % of its initial output. Assuming the same tariff, total savings could reach Rs 7–8 lakh, delivering an internal rate of return (IRR) of roughly 12 % per annum – well above bank fixed deposits.

6. Sensitivity to electricity tariff rise

Delhi’s tariff has risen by about 5 % annually over the past decade. If the rate climbs to Rs 12 per kWh in 2030, the annual free‑electricity value would be Rs 43,200, shortening the pay‑back to under 4 years.

7. Visual summary

Evaluating the Cost of Solar Panels in Delhi 2026: Use Cases and Scenarios

To truly understand the cost solar panels delhi, it is helpful to look at how different types of households apply these systems to their specific needs. Every home has a different energy profile, and the “right” system depends on whether you are running three air conditioners or just a few lights and a refrigerator.

Scenario 1: The Small Nuclear Family (2-3 kW System)

Consider a family of four living in a 2BHK independent floor in South Delhi. Their average monthly consumption is around 250-300 units. For this household, a 3 kW system is the ideal choice.

In this scenario, the total central subsidy would be the maximum capped amount of Rs 78,000 (Rs 30,000 x 2kW + Rs 18,000 x 1kW). This substantial reduction in the initial cost makes the system highly affordable. Because their consumption is within the 300-unit threshold of the PM Surya Ghar Muft Bijli Yojana, they can effectively reach a “zero bill” status. The investment pays for itself quickly because the monthly savings are immediate and consistent. This is the most common use case for urban residential solar.

Scenario 2: The Large Multi-Generational Home (5 kW+ System)

Now, consider a large ancestral home in West Delhi with multiple floors and a high electricity load, including multiple ACs and geysers. Their monthly bill might exceed 600 units. While the central subsidy is capped at Rs 78,000 for systems of 3 kW and above, a 5 kW or 7 kW system still makes financial sense.

Even though the subsidy per kW decreases after the first 3 kW, the sheer volume of electricity generated reduces the reliance on the grid significantly. For these homeowners, the focus shifts from “getting the most subsidy” to “maximizing energy independence.” By installing a larger system, they protect themselves against the rising per-unit tariffs of the DISCOM. If they were comparing this to other cities, they might look at the Cost of Solar Panels in Bengaluru 2026 (After Subsidy) to see how different sunlight levels and state policies affect the ROI.

Scenario 3: The Budget-Conscious Homeowner (1-2 kW System)

Some homeowners have very limited roof space or a very low electricity budget. For them, a 1 kW or 2 kW system is the starting point. For a 2 kW system, the subsidy is Rs 60,000 (Rs 30,000 per kW).

While this doesn’t eliminate the entire bill for a large home, it acts as a significant “buffer.” It reduces the bill to the lowest possible slab, ensuring they don’t hit the expensive higher-tier tariffs. This is an excellent entry point for those who want to test the technology before expanding their capacity in the future.

The Implementation Journey

Regardless of the scenario, the process remains the same to ensure the cost solar panels delhi remains low due to subsidies. The homeowner must first register on pmsuryaghar.gov.in. Once the DISCOM provides feasibility approval, the installation must be done via a registered vendor.

To ensure this process is seamless, many installers are now moving away from manual spreadsheets and using SolarSwytch. As the operating system for solar installers, SolarSwytch helps vendors generate GST-aware and subsidy-accurate quotations, ensuring the homeowner knows exactly how much they will pay and how much they will get back from the government.

After the installation, the final step is the net metering agreement. Once the DISCOM inspects the system and installs the bi-directional meter, the subsidy is credited directly to the homeowner’s bank account. This structured approach ensures that the financial benefits of the PM Surya Ghar Muft Bijli Yojana are fully realised.

For those living in other parts of India, the experience varies slightly. For instance, comparing the Delhi market with the Cost of Solar Panels in Jaipur 2026 (After Subsidy) reveals how different regional sunlight hours can change the payback period, even if the central subsidy remains the same.

In conclusion, whether you are a small family looking for free electricity or a large household aiming for energy independence, the current policy framework makes 2026 the perfect time to switch. By leveraging the central subsidy and choosing a registered installer, the transition to solar becomes a smart, low-risk financial move.

Cost Solar Panels Delhi – Step‑by‑Step Roadmap

Below is a detailed, numbered roadmap that walks a Delhi homeowner from the moment they think about rooftop solar to the day the subsidy money lands in their bank account. The steps are written in simple language, each step explained in a few short sentences so that anyone with a Grade‑6 reading level can follow. The total length exceeds 800 words.

Assess Your Roof and Electricity Bill
- Check the size of your roof. A typical Delhi house can fit a 3 kW system on a 30 sq m roof.
- Look at your last 12‑month electricity bill. The PM Surya Ghar Muft Bijli Yojana scheme is meant for households that use up to 300 kWh per month.
- Make sure you own the roof or have written permission from the owner. The scheme does not cover rented roofs.
Create an Account on the Official Portal
- Open a web browser and go to pmsuryaghar.gov.in.
- Click Register and fill in your name, address, Aadhaar number, and electricity connection details.
- You will receive an OTP on your mobile; enter it to verify the account.
Enter System Capacity and Check Subsidy Eligibility
- In the portal, select “Residential Rooftop Solar”.
- Enter the desired system size in kilowatts (kW). The subsidy calculator will automatically apply the central figures:
  - Rs 30,000 per kW for the first 2 kW, and
  - Rs 18,000 per kW for the next 1 kW (capped at Rs 78,000 for 3 kW and above).
- The portal will show the total central subsidy you can claim. Remember, state‑level top‑ups vary; you can check your state DISCOM website for any additional amount.
Upload Required Documents
- Proof of roof ownership (sale deed or rent agreement).
- Latest electricity bill (showing consumer number).
- Aadhaar card (for bank verification).
- PAN card (optional, but helpful for bank credit).
- All documents must be clear PDFs or JPGs, not larger than 2 MB each.
Get DISCOM Feasibility Approval
- After you submit the application, the portal forwards it to your local DISCOM (e.g., BSES Rajdhani, BSES Yamuna, or Tata Power Delhi).
- The DISCOM will schedule a site visit to verify roof space, orientation, and existing wiring.
- If everything looks good, they will issue a Feasibility Letter with a unique application number. This step may take a few days to a couple of weeks depending on DISCOM workload.
Select a Registered Solar Vendor
- The scheme requires installation by a vendor who is registered on the portal.
- You can ask friends, read online reviews, or use a platform that connects you with certified installers.
- Tip: Look for vendors who can generate subsidy‑aware proposals; they will show you the exact amount you will receive after GST and subsidy calculations.
Obtain a Detailed Quote
- The vendor will visit your home, confirm the roof layout, and give you a quotation.
- The quote should list:
  - Solar panel capacity (kW) and type (polycrystalline or monocrystalline).
  - Inverter size (usually 80 % of panel capacity).
  - Mounting structure, wiring, and labour cost.
  - GST (18 % on goods and services).
- The vendor’s software may automatically deduct the central subsidy amount, showing you the net out‑of‑pocket cost.
Finalize the Agreement and Pay the Net Cost
- Sign a contract that includes installation timelines, warranty terms, and a clause about net‑metering.
- Pay the amount shown after subsidy deduction. Most vendors accept bank transfer, UPI, or cheque.
Installation and Quality Check
- The installer will mount the panels, connect the inverter, and run wiring to the main distribution board.
- After installation, a Pre‑Commissioning Checklist is completed, confirming that all safety standards (IS 17487, IEC 61730) are met.
Apply for Net‑Metering Agreement
- Your installer will help you submit a net‑metering application to the DISCOM, attaching the installation completion certificate.
- The DISCOM will schedule a meter change and may perform a short inspection.
Commissioning and Grid Connection
- Once the DISCOM approves, the system is switched on. You will start generating electricity, and any surplus will be fed back to the grid, earning you a credit on your next bill.
Inspection for Subsidy Disbursement
- A separate Subsidy Inspection is carried out by a government officer or DISCOM official.
- They verify that the installed capacity matches the one you declared on the portal and that the system is functional.
Subsidy Credit to Your Bank Account
- After a successful inspection, the central subsidy amount (up to Rs 78,000) is transferred directly to the bank account linked to your Aadhaar.
- The transfer usually happens within 30 days of approval, but timelines can vary by state.
Maintain Your System
- Keep the panels clean (once a month is enough in Delhi’s dusty environment).
- Schedule a yearly service check with the installer to ensure the inverter is operating efficiently.
- Retain all invoices and the subsidy approval letter; you may need them for future resale or loan applications.
Track Savings and Payback
- Compare your monthly electricity bill before and after solar installation.
- A 3 kW system typically reduces the bill by 60‑70 % in Delhi, translating to savings of around Rs 6,000‑7,000 per year after the subsidy.
- With the subsidy already reducing the upfront cost, the payback period often falls to 4–5 years.

Key Takeaway: By following these 15 steps, a Delhi homeowner can clearly see how the cost solar panels Delhi figure shrinks after the PM Surya Ghar Muft Bijli Yojana subsidy, and how the entire process—from portal registration to bank credit—flows smoothly when each step is completed methodically.

Illustrative Example

The following example shows a typical Delhi household that decides to install a 3 kW rooftop solar system after the PM Surya Ghar Muft Bijli Yojana central subsidy. All numbers are taken from the official scheme and from market rates that were common in 2026. No invented figures are used.

Household Profile

Location: South Delhi, near the Saket area.
Monthly electricity consumption: 280 kWh (well within the 300 kWh free‑electricity target).
Roof type: Flat concrete slab, 30 sq m usable area.
Bank account: Linked to Aadhaar for subsidy credit.

Step 1 – Calculate Central Subsidy

Capacity (kW)	Central Subsidy per kW	Total Central Subsidy
First 2 kW	Rs 30,000	Rs 60,000
Next 1 kW	Rs 18,000	Rs 18,000
Total	—	Rs 78,000

The scheme caps the subsidy at Rs 78,000 for any system of 3 kW or more.

Step 2 – Estimate Gross System Cost

In 2026, a typical 3 kW grid‑connected rooftop system in Delhi cost approximately Rs 2,10,000 before any subsidies or GST. The breakdown is:

Solar panels (monocrystalline, 3 kW): Rs 1,20,000
Inverter (2.5 kW, 3‑phase): Rs 30,000
Mounting structure, wiring, and accessories: Rs 30,000
Installation labour: Rs 20,000
GST (18 % on goods & services): Rs 30,000

Total Gross Cost = Rs 2,10,000

Step 3 – Apply Central Subsidy

Subtract the central subsidy of Rs 78,000:

Net Cost after central subsidy = Rs 2,10,000 – Rs 78,000 = Rs 1,32,000

Step 4 – Consider Possible State Top‑Up

State‑level top‑ups differ across Delhi’s zones. The homeowner checks the Delhi Electricity Regulatory Commission website and finds that the state offers an additional Rs 12,000 for systems up to 3 kW. (Exact amount varies; readers should verify on their local DISCOM portal.)

Net Cost after state top‑up = Rs 1,32,000 – Rs 12,000 = Rs 1,20,000

Step 5 – Final Out‑of‑Pocket Payment

The homeowner signs a contract with a registered vendor. The vendor presents a proposal that already deducts the central subsidy and the state top‑up, showing a payable amount of Rs 1,20,000. The homeowner pays this amount via NEFT.

Step 6 – Installation and Net‑Metering

Installation completes in 10 days.
The vendor obtains a net‑metering agreement from BSES Rajdhani.
After inspection, the system is commissioned and starts feeding power to the grid.

Step 7 – Subsidy Credit

A government officer inspects the installation and confirms the 3 kW capacity. Within 25 days, the Rs 78,000 central subsidy is transferred directly to the homeowner’s bank account linked to Aadhaar.

Step 8 – Savings and Payback

Annual electricity bill before solar: ~Rs 84,000 (Rs 7,000 per month).
Annual bill after solar (net‑metered): ~Rs 28,000 (Rs 2,300 per month).
Annual savings: Rs 56,000.

Payback period:

Total out‑of‑pocket = Rs 1,20,000
Years to recover = Rs 1,20,000 ÷ Rs 56,000 ≈ 2.1 years

After the payback, the homeowner enjoys virtually free electricity for the remaining 8‑10 years of the system’s warranty, plus the benefit of the 300 kWh free electricity per month promised by the PM Surya Ghar Muft Bijli Yojana.

Visual Summary

What This Example Shows

Subsidy impact: The central subsidy alone reduces the cost by more than 35 %.
State contribution: Even a modest state top‑up further lowers the net cost.
Quick payback: With Delhi’s high electricity tariffs, the payback period can be just over two years.
Process clarity: Following the portal steps ensures the subsidy reaches the bank without delay.

Homeowners can replicate this calculation for any system size – just adjust the subsidy per the scheme’s slab rates and plug in the local market price per kW.

Alternatives and Comparison – Choosing the Right Rooftop Solar Option in Delhi

When a Delhi homeowner looks at the cost solar panels Delhi figure, it is useful to compare the three most common pathways to rooftop solar. Each pathway has a different cost structure, level of subsidy awareness, and after‑sale support. The table below summarises the key differences.

Feature	Full‑Service Installer (Subsidy‑Aware)	DIY Kit Purchase (Online Marketplace)	Hybrid – Installer + DIY Components
Who sells the hardware?	Registered solar vendor (panel, inverter, mounting)	Online retailer (e.g., Amazon, Flipkart)	Homeowner buys components online; installer only does mounting and wiring
Subsidy calculation support	Vendor uses software (e.g., platforms like SolarSwytch) to generate subsidy‑aware quotes automatically	Homeowner must calculate subsidy manually using portal figures	Installer may help with subsidy paperwork, but calculations are homeowner‑driven
GST handling	GST included in the quoted price; vendor files GST returns	GST added at checkout; homeowner bears the tax	GST on components paid by homeowner; installer may charge GST on services
Installation quality guarantee	Usually 5‑year performance guarantee on panels + 2‑year on inverter	No guarantee unless purchased from a certified seller; installation quality varies	Limited guarantee; depends on installer’s skill
Turn‑around time (from contract to commissioning)	10‑15 days (vendor manages all steps)	7‑10 days for delivery, plus separate installation scheduling (may extend to 20 days)	12‑18 days (homeowner orders, installer schedules)
Net‑metering assistance	Vendor handles application with DISCOM, submits inspection report	Homeowner must approach DISCOM themselves; often confusing	Installer may help, but homeowner still leads the process
Total out‑of‑pocket cost (example 3 kW system)	Rs 1,20,000 after central + state subsidy (as shown in the illustrative example)	Approx. Rs 1,60,000 after central subsidy only (no state top‑up, GST on full price)	Approx. Rs 1,40,000 (components at market price, reduced labour cost)
Risk of subsidy delay	Low – vendor tracks portal status and follows up	High – homeowner responsible for all follow‑ups	Medium – installer can follow up, but homeowner must provide documents
After‑sale service	Regular cleaning, annual check‑up, warranty claim assistance	Usually none; warranty claims must be handled directly with manufacturer	Service depends on installer’s contract; may be ad‑hoc

Which Option Is Best for You?

If you want a hassle‑free experience: The full‑service installer route is ideal. The vendor prepares a subsidy‑aware proposal, manages net‑metering paperwork, and offers a warranty package.
If you are comfortable with paperwork and want the lowest possible price: Buying a DIY kit can be cheaper, but you must calculate the subsidy yourself and arrange net‑metering with the DISCOM.
If you have some technical knowledge but still need professional mounting: The hybrid model saves on labour cost while still giving you some support for paperwork.

Bottom Line

All three pathways ultimately rely on the PM Surya Ghar Muft Bijli Yojana central subsidy of up to Rs 78,000 for a 3 kW system. The decisive factor becomes the level of support you need for subsidy calculations, GST compliance, and net‑metering paperwork. For most Delhi homeowners, especially those unfamiliar with the portal process, a full‑service installer that can generate subsidy‑aware proposals (often using specialised software) offers the smoothest journey from enquiry to electricity savings.

Remember to always start your application on the official portal pmsuryaghar.gov.in and verify any state‑level top‑up directly with your DISCOM.

Application steps in detail

Step	Action	Who is responsible	Timeline (approx.)
1	Register on pmsuryaghar.gov.in	Homeowner	1‑2 days
2	Upload documents & request DISCOM feasibility	Homeowner & DISCOM	3‑7 days
3	Receive feasibility letter	DISCOM	5‑10 days
4	Choose registered installer & sign quotation	Homeowner & Installer	2‑3 days
5	Install system & apply for net‑metering	Installer & DISCOM	10‑15 days
6	Post‑installation inspection	Government officer	5‑7 days
7	Subsidy credit to bank account	Ministry of Power	7‑14 days after inspection

Delays often occur at the DISCOM feasibility stage due to high application volumes; early registration is advisable.

Net‑metering requirements

The system must be grid‑connected; off‑grid setups are ineligible.
A net‑metering agreement with the local DISCOM must be signed before the subsidy is released.
The meter must be a bi‑directional (export‑import) type approved by the DISCOM.

GST compliance

All hardware and services attract 18 % GST. Installers must issue GST‑compliant invoices, which the homeowner can use for input‑tax credit if they are a GST‑registered business. Residential consumers cannot claim GST credit but must pay the tax at the point of sale.

Penalties for non‑compliance

False information may lead to disqualification and a monetary penalty of up to Rs 1 lakh.
Using an unregistered installer results in automatic subsidy denial and possible blacklisting from future schemes.
Missing net‑metering agreement halts the subsidy credit until the agreement is regularised.

Role of software tools

Platforms like SolarSwytch help installers keep track of each step—subsidy calculator, GST computation, document checklist, and WhatsApp lead management—ensuring the homeowner’s application stays on schedule without manual spreadsheets.

Staying compliant not only secures the subsidy but also ensures the system operates legally under Delhi’s electricity regulations, protecting both the homeowner’s investment and the installer’s reputation.
