APSPDCL (Andhra Pradesh Southern Power Distribution Company Limited), headquartered in Tirupati, is the electricity distributor for the entire southern Andhra Pradesh and Rayalaseema belt, covering Chittoor, Tirupati, Annamayya, Nellore, Kadapa (YSR Kadapa), Kurnool, Nandyal, Anantapur, and Sri Sathya Sai, the nine circles APSPDCL lists on its own website. In 2026, APSPDCL consumers apply for the ₹78,000 PM Suryaghar subsidy through the national portal, with APSPDCL handling the DISCOM-side review in our experience in 10 to 18 working days. The Rayalaseema belt’s 5.5 to 6.0 peak sun hours, among the highest in southern India, push solar payback in APSPDCL territory down to 3.2 to 3.5 years.
This guide walks through every step of the PM Suryaghar APSPDCL process, the documents APSPDCL specifically flags, the rejection patterns we see most often across our Tirupati, Nellore, and Kurnool installations, and how to track the application from registration to subsidy disbursement. It also covers cyclone-belt design notes that matter on the Nellore coast.
Direct answer. PM Suryaghar APSPDCL applications follow six stages: portal registration, DISCOM feasibility (10 to 18 days in our experience), choice of a vendor registered on the national portal, installation, APSPDCL net meter inspection (7 to 14 days), and release of the subsidy, which MNRE’s guidelines say is processed within 15 days of the DISCOM’s approval on the portal. Maximum central subsidy is ₹78,000 for 3 kW and above. Heaven Green Energy is empanelled across all APSPDCL districts.
If you’re at the stage of checking your bill header for “APSPDCL” or “ఆంధ్ర ప్రదేశ్ సదరన్ పవర్” and wondering whether your application will move quickly, yes, APSPDCL processes most clean applications within the published timelines. Most delays come from document errors on the consumer side, not from APSPDCL’s renewable cell.
APSPDCL Coverage Area: Southern AP and Rayalaseema
Andhra Pradesh has three DISCOMs: APSPDCL covers the southern + Rayalaseema belt from its Tirupati headquarters, APCPDCL covers the central coastal belt (Krishna, Guntur, Prakasam), and APEPDCL covers the north-eastern coastal belt (Visakhapatnam, Godavari districts). The PM Suryaghar process you follow depends entirely on which DISCOM bills your home.
| District / City | DISCOM | Note |
|---|---|---|
| Tirupati | APSPDCL | Tirupati city, Renigunta, temple-belt service connections |
| Chittoor | APSPDCL | Chittoor, Madanapalle, Punganur |
| Nellore (SPSR Nellore) | APSPDCL | Nellore city, Gudur, Kavali, Atmakur |
| YSR Kadapa | APSPDCL | Kadapa, Proddatur, Pulivendula, Rayachoti |
| Kurnool, Nandyal | APSPDCL | Kurnool, Adoni, Nandyal, Yemmiganur |
| Anantapur | APSPDCL | Anantapur, Hindupur, Tadipatri |
| Sri Sathya Sai | APSPDCL | Puttaparthi, Dharmavaram, Penukonda |
| Annamayya | APSPDCL | District carved from Kadapa and Chittoor |
| Visakhapatnam, Vizianagaram, Srikakulam | APEPDCL | Not APSPDCL |
| East/West Godavari | APEPDCL | Not APSPDCL |
| Krishna, NTR, Guntur, Prakasam | APCPDCL | Not APSPDCL |
If your monthly bill header reads “Andhra Pradesh Southern Power Distribution Company Limited” or shows the Tirupati corporate-office address, you’re an APSPDCL consumer and this guide applies. For the other two AP DISCOMs, refer to the national PM Suryaghar complete guide; for the neighbouring Tamil Nadu sibling DISCOM, see the PM Suryaghar TANGEDCO process.
PM Suryaghar Subsidy for APSPDCL Consumers
PM Suryaghar: Muft Bijli Yojana is administered by the Ministry of New and Renewable Energy (MNRE). The central subsidy is fixed nationally, APSPDCL itself does not set the rate, but APSPDCL’s net meter approval is the trigger that releases the subsidy payment to the consumer’s account.
| System Size | Central Subsidy (MNRE) | Best for |
|---|---|---|
| 1 kW | ₹30,000 | Monthly bill under ₹1,000 |
| 2 kW | ₹60,000 | Monthly bill ₹1,500–₹2,500 |
| 3 kW | ₹78,000 | Monthly bill ₹2,500–₹4,500, maximum subsidy |
| 4 kW and above | ₹78,000 (capped) | High-consumption homes; extra kW at full cost |
| RWA / Group Housing | ₹18,000 / kW | Common-area loads only (lifts, lighting, pumps) |
The subsidy is paid by Direct Benefit Transfer (DBT) to the bank account you register on the portal (or to your loan account if you financed the system). Under MNRE’s June 2024 guidelines it is processed within 15 days of APSPDCL approving the inspection on the national portal, after you redeem the e-token in your portal login. APSPDCL does not handle the money; it signs off the inspection and MNRE releases the payment.
Check with the AP New & Renewable Energy Development Corporation (NREDCAP) and APSPDCL for any state component announced for specific categories of households. The central ₹78,000 is the figure that applies to every APSPDCL residential consumer, and you should plan your finances around it.
Real numbers, Tirupati 3 kW system. A 3 kW system in Tirupati costs ₹1.60–₹1.80 lakh installed. After the ₹78,000 subsidy, your out-of-pocket is ₹82,000–₹1,02,000. The system generates ~440 kWh/month on Rayalaseema PSH of 5.7 average. At an assumed upper-slab tariff of about ₹8.50/kWh, blended savings work out to roughly ₹3,100–₹3,400 per month. Payback: 26 to 32 months from commissioning.
For a complete subsidy breakdown including stacking rules and category-wise eligibility, see the PM Suryaghar complete guide.
The 6-Stage APSPDCL PM Suryaghar Funnel
This is the framework we use across our APSPDCL installations, six sequential stages, each with its own dependencies. Skip a stage and you create a rework cycle that adds 2 to 3 weeks. We call it The 6-Stage APSPDCL PM Suryaghar Funnel and apply it identically in Tirupati, Nellore, Kurnool, and the Rayalaseema interior.
Stage 1: Pre-Application Preparation (Day 0 to 3)
Before opening pmsuryaghar.gov.in, get the following ready.
Check your APSPDCL service number: APSPDCL bills carry a “SC No.” (Service Connection Number) on the monthly bill. This is the field the national portal pulls account data from; enter it exactly as printed.
Check your sanctioned load: printed as “Contracted Load” or “Sanctioned Load (kW)” on the bill. DISCOMs commonly cap rooftop capacity at the sanctioned load, so a home with 3 kW sanctioned load planning a larger system should expect a load enhancement request through the local APSPDCL section office.
Verify your bank details: the subsidy is credited to the bank account you register on the portal, supported by a cancelled cheque, passbook or e-statement in your name. Make sure the account is active and in the applicant’s name; many applicants also confirm Aadhaar seeding at their branch as a precaution.
Confirm name consistency: the name on your APSPDCL bill, Aadhaar, and bank account must match. Even a minor difference (an extra “S/o” prefix, or Telugu vs English spelling variants like “Venkateswara” vs “Venkateshwara”) triggers a Suryaghar Aadhaar–name mismatch rejection.
Stage 2: Portal Registration & DISCOM Submission (Day 4)
Open the national portal, register with your mobile number, and trigger an OTP. Once logged in:
- Select state: Andhra Pradesh.
- Select DISCOM: APSPDCL.
- Enter your SC number and bill month.
- The portal pulls your account details from APSPDCL’s database. Verify name, address, and sanctioned load against your bill.
- Choose your desired system capacity (1, 2, 3 kW or above).
- Upload Stage 1 documents (see §Documents Checklist below).
- Submit the application, the portal generates an application reference number (ARN).
The ARN is what you’ll use for every follow-up, save it and screenshot the confirmation page. APSPDCL then receives the application in its internal queue for feasibility review by the Assistant Engineer (Renewable) at your servicing section office.
Stage 3: APSPDCL Feasibility Approval (Day 5 to 22)
Under the Electricity (Rights of Consumers) Rules, rooftop systems up to 10 kW are meant to be deemed feasible without a technical feasibility study; until a state operationalises this, the DISCOM still reviews the application. In practice, APSPDCL’s renewable energy cell looks at three things:
- Distribution transformer capacity: your local DT must have headroom for the proposed rooftop export. APSPDCL maintains a transformer-loading database via its SCADA system; over-loaded DTs trigger a conditional approval (you can install, but export capping applies).
- Sanctioned load match: system size must equal or be less than sanctioned contracted load.
- Documentation completeness: clear Aadhaar, valid bill, ownership proof.
Approval is normally 10 to 18 working days. If your DT is loaded above 90%, APSPDCL may issue a conditional clearance asking you to limit export, accept it; the financial impact on PM Suryaghar payback is minor because Rayalaseema homes self-consume most of the generated units in the same daytime window. If APSPDCL asks for additional documents, respond promptly on the portal; slow replies are the most common cause of avoidable delay.
Stage 4: Vendor Selection & Installation (Day 23 to 45)
After feasibility approval, you choose a vendor registered on the national portal for Andhra Pradesh. You choose one, and this is the single decision that determines whether your installation runs smoothly or stalls for months.
Heaven Green Energy is empanelled across all APSPDCL districts and operates dedicated teams in Tirupati, Nellore, Kurnool, Anantapur, and Kadapa. Installation typically takes 2 to 4 working days for a 3 kW residential system, including structure fabrication, panel mounting, inverter wiring, and earthing.
During installation, your installer must use ALMM-listed DCR panels (modules made in India from Indian cells, which MNRE requires for the subsidy) and BIS-certified inverters (Bureau of Indian Standards, conforming to IS 16221 / IEC 62109). Non-DCR modules make the installation ineligible for the subsidy.
For coastal areas (Nellore and coastal parts of Tirupati district) the structure design needs an extra wind-loading factor. Bay of Bengal cyclone season runs October–December and our coastal installs use 75 to 80 micron galvanised structures rated for 200+ km/h gust loads, with stainless fasteners and an additional cyclone-region tie-down per IS 875 (Part 3).
Watch out
Some vendors quote a price that assumes a non-DCR panel, or use 50-micron structures that fail wind loading in coastal Nellore. The quote looks cheaper, but a non-DCR panel makes the installation ineligible (and you lose the ₹78,000 subsidy) or the structure fails the first cyclone season. Always verify the panel model is a DCR module on the current ALMM list and that the structure carries an IS 875 wind-loading certificate before signing.
Stage 5: APSPDCL Net Meter Inspection (Day 46 to 60)
Once installation is complete, your vendor uploads commissioning documents to the portal, installation photos, single-line diagram, earth pit photos, panel and inverter serial numbers. APSPDCL then schedules a physical inspection within 7 to 14 working days.
The APSPDCL field engineer (Assistant Engineer, Operations) checks:
- Panel count and model match the application.
- Inverter make, model, and serial number match.
- Earthing is per IS 3043 standard with two independent earth pits.
- Module mounting structure is corrosion-resistant (galvanised steel or aluminium) and rated for the local wind zone.
- AC and DC isolators are correctly placed and labelled.
- Existing single-direction meter is replaced with a bi-directional net meter, properly sealed by the APSPDCL meter division.
After inspection, APSPDCL commissions the bi-directional meter and issues the commissioning report on the portal. This is the trigger document for the central subsidy payment.
Stage 6: Subsidy DBT Disbursement (Day 61 to 90)
Once APSPDCL approves the inspection on the portal, you redeem the e-token in your portal login and MNRE processes the subsidy, within 15 days of the DISCOM’s approval under its guidelines. The credit goes to the bank account registered on the portal.
If the subsidy doesn’t arrive, raise a grievance on the portal with your application number. MNRE’s guidelines set a 30-day window for resolving grievances. Common reasons for delay are wrong or inactive bank details, which are consumer-side, not APSPDCL’s.

APSPDCL Net Metering and APERC Tariff
APSPDCL follows the Andhra Pradesh Electricity Regulatory Commission (APERC) framework for net metering. For how this compares across DISCOMs nationally, see this state-by-state net metering process guide. Check the current APERC regulations and APSPDCL’s net-metering instructions for the exact capacity limits and settlement rate before you size the system. In broad terms:
- Capacity: residential rooftop systems connect under net metering; capacity is generally linked to your contracted load.
- Export credit: surplus left over at settlement is paid at a regulator-set rate that is well below the retail tariff you save, so the economics favour self-consumption.
- Billing cycle: net units are calculated each billing cycle, with any surplus settled as the regulations specify.
APSPDCL Domestic Tariff
Domestic tariffs in Andhra Pradesh are slab-based and set by APERC in its annual retail supply tariff order; check the current APERC tariff order or your bill for the rates that apply. Fixed charges, customer charges, and electricity duty are billed separately. A typical Tirupati 3-BHK consuming 400 to 450 kWh/month sits in the upper slabs, and solar self-consumption shaves the highest-tariff units first.
The Tirupati temple economy adds an interesting twist: small businesses, choultries, and ashrams in the temple belt sit on commercial tariffs, which are higher than domestic ones. Note that PM Suryaghar’s subsidy covers residential connections only.
Common APSPDCL Application Rejection Reasons
Across residential installations we tracked in APSPDCL territory through 2024 to 25, rejections cluster around six patterns. These are all preventable with a 10-minute pre-check.
-
1
Name mismatch between Aadhaar and APSPDCL bill. Telugu/English spelling variants are the biggest culprit. Resolve via the APSPDCL "name correction" application at your section office before applying.
-
2
Sanctioned load smaller than proposed system. File for a load enhancement at the local section office first; it adds 15 to 25 days but saves the entire application.
-
3
Roof photograph rejected. Submit a daytime photo showing all four corners and surrounding shading sources. Avoid wide-angle distortion and night shots taken on a phone torch.
-
4
Ownership proof missing. For inherited property in Rayalaseema villages, attach a registered settlement deed or a current property tax receipt in the applicant's name; oral inheritance does not pass APSPDCL's checks.
-
5
Society NOC format wrong. APSPDCL requires NOC on society letterhead with secretary signature and Registrar of Societies registration number, generic typed letters without registration details get rejected.
-
6
Bank details wrong or account inactive. The subsidy is credited to the bank account registered on the portal; a closed, inactive or mismatched account means the payment fails and has to be re-processed.
For the full taxonomy of rejection causes and the recovery steps for each, read our PM Suryaghar rejection reasons guide. For a sibling DISCOM comparison, what the same process looks like in Rajasthan, see the PM Suryaghar JVVNL process.
Cost, ROI, and Payback for Andhra Homes
Southern Andhra’s combination of strong solar irradiance and high upper-slab tariffs gives APSPDCL consumers some of the best rooftop economics in India. The numbers below assume Rayalaseema PSH of 5.7/day average, a 75% performance ratio, and a blended tariff of ₹7.20/kWh after slab-mix calculation for a typical 350 to 450 kWh/month household.
| System size | All-in cost (Heaven Green) | After ₹ subsidy | Annual generation | Annual savings | Payback |
|---|---|---|---|---|---|
| 1 kW | ₹62,000–₹72,000 | ₹32,000–₹42,000 | 1,600 kWh | ₹11,500 | 3 to 3.5 yrs |
| 2 kW | ₹1.15–₹1.30 lakh | ₹55,000–₹70,000 | 3,200 kWh | ₹22,000 | 2.8 to 3.2 yrs |
| 3 kW | ₹1.60–₹1.80 lakh | ₹82,000–₹1.02 lakh | 4,800 kWh | ₹35,500 | 2.5 to 3 yrs |
| 5 kW | ₹2.55–₹2.80 lakh | ₹1.77–₹2.02 lakh | 8,000 kWh | ₹58,500 | 3 to 3.4 yrs |
Assumptions for the table above: Rayalaseema 5.7 PSH/day average, 75% performance ratio, blended tariff of ₹7.20/kWh after slab-mix calculation, system degradation 0.5%/year. For an interactive calculation specific to your APSPDCL bill, use the Heaven Green solar calculator, it pulls your slab structure and shows your specific payback in 60 seconds.
Verdict. A 3 kW PM Suryaghar system in APSPDCL territory is the sweet spot. It hits the maximum subsidy of ₹78,000, fits within most residential sanctioned loads, generates enough to cover the highest-slab units, and pays back in about three years on our estimates. Smaller systems waste subsidy headroom; larger systems don’t get extra subsidy.
Pros and Cons of PM Suryaghar in APSPDCL Territory
- Plus Strong irradiance in Rayalaseema, 5.5 to 6.0 PSH/day
- Plus ₹78,000 central subsidy released directly to your bank
- Plus APSPDCL feasibility typically 10 to 18 working days in our experience
- Plus Net metering available for residential rooftop systems
- Plus Estimated payback around 3 years for 3 kW systems in Tirupati, Kurnool, Anantapur
- Plus High upper-slab retail tariffs make self-consumption highly valuable
- Minus Export settlement rate far lower than retail savings
- Minus Coastal Nellore and Tirupati need cyclone-rated structures (extra cost)
- Minus APSPDCL inspector availability slows down rural Kurnool and Anantapur
- Minus Summer heat above 42°C lowers panel output 7 to 9% in Anantapur
- Minus Surplus left at settlement earns far less than self-consumed units
- Minus Vendor quality varies sharply outside Tirupati and Nellore cities
The pros dominate for any household whose monthly bill consistently sits above ₹2,500. Below that threshold, the subsidy still applies but the absolute savings are smaller and payback drifts toward 4.5 to 5 years. For temple-belt commercial consumers (choultries, ashrams, small hotels), solar can make sense on the higher commercial tariff, but outside PM Suryaghar, which is residential only.

Frequently Asked Questions
How long does the APSPDCL PM Suryaghar process take from application to subsidy?
In our experience the complete timeline from portal submission to subsidy DBT runs 60 to 90 days for a clean application in APSPDCL territory. Feasibility approval takes 10 to 18 working days, installation 3 to 5 days, APSPDCL net meter inspection 7 to 14 days, and MNRE’s guidelines provide for the subsidy to be processed within 15 days of the DISCOM’s approval. Delays usually come from document errors, sanctioned-load mismatches, or distribution transformer loading issues, all preventable with a Stage 1 pre-check.
What is the maximum subsidy an APSPDCL consumer can claim under PM Suryaghar?
The maximum central subsidy is ₹78,000 for any system 3 kW or larger. Smaller systems get ₹30,000 for 1 kW and ₹60,000 for 2 kW. Resident Welfare Associations and group housing societies installing solar for common-area loads get ₹18,000 per kW with a cap based on the total dwelling count. These rates are fixed by MNRE nationally and do not vary by DISCOM, whether you are billed by APSPDCL, APCPDCL or APEPDCL.
Can I install solar in APSPDCL territory if my sanctioned load is less than my desired system size?
Usually you will need a load enhancement at your local APSPDCL section office first, then proceed with PM Suryaghar. The load enhancement is a separate application that takes 15 to 25 days in our experience. Skipping it commonly causes a feasibility query. Heaven Green can file both in parallel to minimise total delay. A 3 kW solar system requires at least 3 kW sanctioned contracted load on your APSPDCL bill.
Does APSPDCL pay for surplus solar units exported to the grid?
Surplus left over at settlement is paid at a regulator-set rate that is well below the retail tariff. This means self-consumption is worth far more than export, especially in the upper domestic slabs. Your system should be sized to match your daytime consumption profile, not maximised for export. Check the current APERC regulations for the exact settlement rate and period.
What documents does APSPDCL specifically require beyond the standard PM Suryaghar list?
APSPDCL accepts the standard MNRE document set: paid APSPDCL bill within the last three months, Aadhaar, cancelled cheque or passbook page, ownership proof (property tax receipt or sale deed), and roof photograph. For rural homes in Kurnool and Anantapur, some section offices ask for the patta passbook as additional ownership proof. For flats and group housing, the society NOC must be on society letterhead with the secretary’s signature and the Registrar of Societies registration number.
Which APSPDCL districts have the fastest application processing?
In our experience Tirupati and Nellore urban circles process applications fastest, typically 10 to 12 working days for feasibility. Kurnool, Anantapur, and Kadapa run 12 to 15 days. Rural sub-divisions in Annamayya and Sri Sathya Sai can take 15 to 18 days because of Assistant Engineer travel logistics. Submitting between November and February avoids the summer-monsoon backlog.
What happens if APSPDCL rejects my PM Suryaghar application?
Under MNRE’s guidelines a DISCOM can send an application back for corrections or reject it with reasons on the portal. Where it is sent back, you can fix the flagged issue without restarting from scratch. The most common fixes are document re-uploads (Aadhaar with corrected spelling, ownership proof) and sanctioned-load corrections. For complex cases, raise a grievance through the national portal; MNRE’s guidelines set a 30-day window for resolving grievances.
Is PM Suryaghar subsidy applicable for solar systems with battery storage in APSPDCL territory?
The central PM Suryaghar subsidy is calculated only on the solar module capacity of the system, batteries are not subsidised under this scheme. You can still install a battery-backed hybrid system in APSPDCL territory; the solar capacity portion claims the ₹78,000 subsidy as normal, and you fund the battery separately. Most southern AP households go grid-tied without batteries, the APSPDCL grid is reasonably stable in urban Tirupati and Nellore. Battery makes more sense in rural Anantapur and Annamayya where outage hours are higher; payback then adds 3 to 4 years to the ROI.
Do cyclone-zone homes in Nellore and coastal Tirupati need a different solar structure?
Yes. Coastal areas in APSPDCL territory, particularly Nellore and coastal parts of Tirupati district, are exposed to Bay of Bengal cyclones during October–December. Heaven Green uses 75 to 80 micron galvanised steel structures rated for 200+ km/h gust loads, with stainless fasteners and additional cyclone-region tie-downs per IS 875 (Part 3). This adds ₹5,000–₹8,000 per kW to the structure cost but is mandatory for warranty and insurance to remain valid. Inland Rayalaseema districts (Anantapur, Kurnool, Kadapa) do not need cyclone-rated structures.
