Solar Calculator Andhra Pradesh 2026
Work out panel size, PM Surya Ghar subsidy and monthly savings for your home under APSPDCL, APEPDCL or APCPDCL.
1 Your electricity
Enter your 6-digit PIN to auto-fill your district's average daily generation from NASA satellite data. You can always edit it below.
Indian residential tariffs typically run ₹6–₹9 per unit and rise every year. Check a recent bill for your exact slab rate.
2 Cost & generation
A complete on-grid setup (panels, inverter, structure, wiring, installation) runs about ₹50,000–₹60,000 per kW in 2026. Tier-1 brands (Tata, Adani, Waaree) cost a little more.
Most of India gets about 4 units (kWh) per kW per day on average; sunnier states (Rajasthan, Gujarat) can reach 4.5–5.
3 Subsidy & state top-up
Central subsidy: ₹30,000/kW up to 2 kW, +₹18,000 for the 3rd kW, capped at ₹78,000 for any system 3 kW and above (residential, up to 10 kW). As of May 2026 (per MNRE). Always confirm current rates at pmsuryaghar.gov.in before applying.
Some states add their own subsidy on top of the central one (e.g. Gujarat has offered ₹10,000/kW). Enter your state's per-kW top-up if any — leave 0 if unsure. Verify with your DISCOM.
4 How you'll pay
Indicative estimates only. Subsidy rules and tariffs change by government notification and vary by state/DISCOM. Assumes a gradual annual tariff rise and panel degradation. Confirm current PM Surya Ghar rates and get installer quotes before purchasing.
How PM Surya Ghar subsidy is calculated
• Up to 2 kW:
₹30,000 per kW (1 kW = ₹30,000; 2 kW = ₹60,000)• 3rd kW:
+₹18,000 (so 3 kW = ₹78,000)• 3 kW and above: capped at
₹78,000 (no extra above 3 kW; residential eligibility up to 10 kW)Net cost =
system cost − central subsidy − state top-up. Annual savings = annual units generated × tariff (capped at your usage). Payback = net cost ÷ annual savings; the free-electricity date is today plus the payback period.

Rooftop Solar in Andhra Pradesh
Andhra Pradesh supplies electricity through three DISCOMs: APSPDCL across the south-central districts, APEPDCL in the north-east around Visakhapatnam, and APCPDCL in the central region. All three bill under the same APERC retail schedule, so a rooftop plan behaves similarly whether you live in Tirupati, Vizag or Vijayawada.
Net metering and tariffs
In 2025 APERC moved to waive application, feasibility and net-metering charges for domestic rooftop systems up to 10 kW under PM Surya Ghar, which lowers the paperwork cost of going solar. Under net metering, units you export offset units you import, so every self-consumed unit saves the full retail rate. Domestic slabs are stepped, and a mid-to-high consumption home effectively pays in the region of Rs 7 per unit, though your own slab may differ.
Sunshine and generation
Andhra Pradesh is one of the sunnier states, averaging roughly 4.5 units per installed kW per day across the year. A 3 kW array therefore generates close to 4,900 units annually. Coastal humidity and the monsoon shave a little off peak summer output, but winter and post-monsoon months stay consistently productive across most districts. You can size a system against your own bill with our system size calculator and confirm output with the on-grid solar calculator.
How PM Surya Ghar applies
The national PM Surya Ghar subsidy pays Rs 30,000 per kW for the first 2 kW, plus Rs 18,000 for the third kW, capping at Rs 78,000 for 3 kW and above. It is credited by DBT after commissioning, and a collateral-free loan near 7 percent is available up to Rs 2 lakh.
- 1 to 2 kW: Rs 30,000 per kW
- 3 kW and above: Rs 78,000 total
Worked example
Take a 3 kW rooftop system in Guntur. At about 4.5 units per kW it yields near 4,900 units a year. Offsetting consumption at roughly Rs 7 per unit, that is close to Rs 34,000 saved annually before any export credit. After the Rs 78,000 subsidy, a typical installed cost pays back in only a few years. Compare loan routes with the solar loan EMI calculator or estimate lifetime savings using the savings calculator.
Tariff slabs and net-metering rules are revised periodically, so treat these figures as a guide and verify current APERC orders before you commit. For a nationwide view, start with our India solar calculator.

Frequently asked questions
APSPDCL, APEPDCL or APCPDCL depending on your district; all follow APERC net-metering rules, and applications up to 10 kW go through the PM Surya Ghar portal.
The central PM Surya Ghar subsidy gives Rs 30,000 per kW up to 2 kW and Rs 78,000 for 3 kW or more; there is currently no separate per-kW state capital subsidy.
Roughly 4.5 units per day on average, or about 1,600 units a year, varying with season, shading and panel orientation.
APERC has waived net-metering and application charges for domestic systems up to 10 kW under PM Surya Ghar, though you still pay for the meter and installation.
