High monthly electricity bills are one of the fastest-growing recurring expenses for Indian households. With rising domestic slab tariffs, heavy summer air conditioning usage, and expanding home appliance loads, families across Andhra Pradesh frequently see their monthly utility bills climb beyond manageable levels. While rooftop solar offers an obvious solution, high upfront capital costs previously discouraged many homeowners from transitioning.
The central government launched the PM Surya Ghar: Muft Bijli Yojana to eliminate this financial barrier. Backed by a national budgetary outlay aiming to power one crore households, the scheme provides substantial, direct capital subsidies that cut the net cost of a residential solar system significantly. Instead of routing funds through complex bureaucratic intermediaries, the central financial assistance is deposited straight into the applicant's verified bank account.
However, securing this financial assistance requires strict compliance with technical, vendor empanelment, and metering guidelines. From understanding why commercial enterprises are excluded to navigating the mandatory DCR panel rules, this guide explains everything you need to know to maximise your savings through residential rooftop solar.
PM Surya Ghar Subsidy Slabs and Financial Structure
The financial assistance under PM Surya Ghar is structured on a capacity-tiered slab system administered by the Ministry of New and Renewable Energy (MNRE). The scheme categorises domestic rooftop plants based on their DC nameplate capacity:
- 1 kW System Capacity: Receives a direct central subsidy of ₹30,000. This capacity suits small independent houses with basic lighting, ceiling fans, a refrigerator, and television.
- 2 kW System Capacity: Receives a direct central subsidy of ₹60,000 (calculated at ₹30,000 per kW for the first two kilowatts). This setup is ideal for medium-sized homes with regular appliance usage and occasional single-room air conditioning.
- 3 kW System Capacity: Receives an additional ₹18,000 for the third kilowatt, bringing the total financial assistance to ₹78,000.
- Above 3 kW Capacity (e.g., 4 kW to 10 kW): The subsidy amount is permanently capped at ₹78,000. Homeowners who require larger systems to offset multi-split air conditioners or electric vehicle home chargers can install higher capacities, but the central financial assistance will not exceed this ceiling.
For group housing societies and residential welfare associations (RWAs), the scheme provides ₹18,000 per kW for common facility solar plants (such as lifts, water booster pumps, and common staircase lighting), up to an aggregate cap of 500 kW per residential society.
Direct Benefit Transfer (DBT): The entire subsidy is released via DBT directly to your bank account after system commissioning and DISCOM net meter synchronization. You do not have to wait for vendor discounts or paper voucher clearances.
Who Is Eligible for PM Surya Ghar Subsidy?
While the PM Surya Ghar initiative is expansive, eligibility is governed by clear regulatory boundaries. To qualify for central financial assistance, an applicant must fulfill the following mandatory conditions:
- Domestic Residential Connection: The electricity connection at the premises must be registered under a domestic or residential tariff category with the local DISCOM (such as APSPDCL in southern Andhra Pradesh). Commercial shops, private clinics operating out of residential frontages, workshops, and agricultural connections are strictly ineligible.
- Rooftop Rights and Structural Suitability: The applicant must possess legal ownership or permanent access rights to the roof or terrace space. The rooftop must be shadow-free and structurally sound to support mounting structures and modules.
- Grid-Connected System: Only grid-tied (on-grid) systems and grid-interactive hybrid systems with bi-directional net metering qualify. Standalone, off-grid battery installations without utility grid synchronization cannot receive the subsidy.
- Empanelled Vendor Execution: The installation must be executed through a vendor registered on the national portal (https://www.pmsuryaghar.gov.in). Self-installations or purchases from unregistered third-party traders are immediately rejected.
The DCR Module Mandate: Why Panel Origin Dictates Your Subsidy
One of the most critical aspects of the PM Surya Ghar scheme is the Domestic Content Requirement (DCR). Under MNRE guidelines, every solar module installed under a subsidised rooftop project must be composed of domestically manufactured solar cells and assembled in an Indian manufacturing facility listed under the Approved List of Models and Manufacturers (ALMM).
In the open market, non-DCR panels (which often assemble imported silicon cells into Indian frames) are widely sold for commercial and industrial projects at a lower price point. However, installing non-DCR panels on a residential rooftop will result in immediate disqualification on the national portal during the technical document verification stage.
Because domestic cell manufacturing carries higher capital costs, DCR modules carry a price premium of approximately ₹9 to ₹12 per Wp (roughly ₹9,000 to ₹12,000 per kWp) compared to non-DCR equivalents. Despite this component premium, the substantial ₹78,000 central subsidy far outweighs the incremental cost, resulting in exceptionally attractive net economics for homeowners.
Commercial sector exclusion: Commercial, industrial, and institutional entities cannot claim PM Surya Ghar subsidies. Businesses looking to cut operational electricity expenses should explore accelerated depreciation tax deductions, open-access options, and our commercial solar offerings.
System Sizing, Generation Estimates, and Financial Payback
Determining the right solar system capacity depends on your current monthly electricity consumption and available shade-free terrace area. In Andhra Pradesh, climatic conditions offer excellent solar insolation throughout the year.
As a dependable rule of thumb, each 1 kWp of installed rooftop solar in this region produces approximately 4 to 4.5 units (kWh) of clean electricity per day on an annualised basis. This translates into roughly 1,400 to 1,600 units per kW per year. Physically, each kilowatt requires approximately 80 to 100 square feet of shadow-free roof area.
The following table outlines how typical residential capacities correlate with roof requirements, central subsidy assistance, and generation outputs:
| System Capacity | Shade-Free Roof Area | PM Surya Ghar Subsidy | Est. Monthly Generation | Ideal Monthly Bill Pre-Solar |
|---|---|---|---|---|
| 1 kW System | 80 – 100 sq ft | ₹30,000 | 120 – 135 units | ₹800 – ₹1,500 |
| 2 kW System | 160 – 200 sq ft | ₹60,000 | 240 – 270 units | ₹1,800 – ₹3,000 |
| 3 kW System | 240 – 300 sq ft | ₹78,000 (Maximum Cap) | 360 – 405 units | ₹3,200 – ₹5,500 |
| 4 kW System | 320 – 400 sq ft | ₹78,000 (Capped) | 480 – 540 units | ₹5,000 – ₹7,500 |
| 5 kW System | 400 – 500 sq ft | ₹78,000 (Capped) | 600 – 675 units | ₹7,000 – ₹11,000 |
| 10 kW System | 800 – 1,000 sq ft | ₹78,000 (Capped) | 1,200 – 1,350 units | ₹15,000+ |
For a standard 3 kW residential setup offsetting high slab tariffs, the combination of ₹78,000 in central assistance and ongoing electricity bill reduction typically delivers full capital payback within 3 to 4 years, depending on grid tariffs and site conditions. After this breakeven period, the system delivers essentially free electricity for the remainder of its 30-year operational life.
DISCOM Integration and Net Metering in Andhra Pradesh
A subsidised solar system relies on a bi-directional net meter provided and calibrated by your electricity distribution company (such as APSPDCL). Net metering records the exact units of electricity your solar plant feeds into the grid during peak daytime generation, as well as the units you draw from the grid during the night.
At the conclusion of each billing cycle, your DISCOM offsets exported units against consumed units. If your solar generation matches or exceeds your monthly consumption, your energy consumption charge drops to zero, leaving only nominal fixed meter charges and electricity duties on your bill. Any surplus units generated during sunny months are credited forward to subsequent billing cycles in accordance with state net-metering regulations.
Sanctioned load rule: Under DISCOM regulations, your approved solar plant capacity cannot exceed your sanctioned connected load. If your current sanctioned load is 2 kW and you want to install a 3 kW system to claim the full ₹78,000 subsidy, you must submit a load enhancement request to your DISCOM alongside your solar application.
The 31 March 2027 Deadline and Application Process
The PM Surya Ghar: Muft Bijli Yojana has an officially notified implementation timeline running up to 31 March 2027. Because national budgetary targets and subsidy allocations are subject to periodic review, waiting until the final months of the scheme risks facing portal processing backlogs, DISCOM net meter supply constraints, and potential policy revisions.
The application journey involves registering on the national portal, selecting an empanelled vendor, securing DISCOM technical feasibility, completing physical installation, executing net-meter testing, and uploading commissioning documentation. A complete walkthrough of each administrative milestone is available in our companion guide on how to apply for PM Surya Ghar.

To assist homeowners who prefer financing over upfront capital expenditure, nationalized and private banks offer collateral-free solar loans at subsidised interest rates starting from roughly 7% per annum. As explored across our residential on-grid solutions, the monthly electricity bill savings often exceed the loan EMI, making rooftop solar immediately cashflow-positive from month one.

Frequently asked questions
Can I receive more than ₹78,000 in subsidy if I install a 5 kW or 10 kW residential system?
No. Under PM Surya Ghar: Muft Bijli Yojana guidelines, the Central Financial Assistance (CFA) is strictly capped at ₹78,000 for all residential rooftop installations of 3 kW capacity and above. While you can install a 5 kW or 10 kW system depending on your roof space and sanctioned load, the maximum central subsidy credit remains ₹78,000.
Can commercial shops, small factories, or rented offices claim the PM Surya Ghar subsidy?
No. The PM Surya Ghar subsidy is exclusively available for domestic residential electricity connections. Commercial, industrial, and institutional consumers are not eligible for this residential financial grant, although businesses can leverage accelerated depreciation tax benefits and commercial solar savings.
What is a DCR solar panel and why is it mandatory for PM Surya Ghar?
DCR stands for Domestic Content Requirement. For a solar panel to qualify as DCR, both the solar cells and the module assembly must be manufactured within India under MNRE's ALMM regulations. Using non-DCR or imported modules will disqualify your installation from receiving the PM Surya Ghar subsidy on the national portal.
How long does it take for the subsidy amount to be credited to my bank account?
Once physical installation, net meter commissioning by your local DISCOM (such as APSPDCL), and joint portal inspection submissions are completed, the central subsidy is transferred directly via Direct Benefit Transfer (DBT) into the homeowner's Aadhaar-linked bank account within approximately 30 days.
Can I install solar panels myself or hire a local electrician to claim the subsidy?
No. To claim the subsidy, you must execute your installation through a registered and empanelled EPC vendor on the national portal (https://www.pmsuryaghar.gov.in). The vendor is responsible for submitting technical drawings, ALMM DCR certificates, safety compliance reports, and facilitating DISCOM inspection.
