Solar Calculator Odisha 2026
Size a rooftop system for your Odisha home and see cost, payback and PM Surya Ghar subsidy of up to 78,000 with Tata Power net metering.
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 Odisha
Odisha is served by four Tata Power distribution companies carved out by region: TPCODL in the central zone around Bhubaneswar and Cuttack, TPWODL in the west, TPSODL in the south and TPNODL in the north. Whichever covers your area handles the net-metering connection. TPCODL has waived processing and net-metering fees to encourage rooftop adoption, and domestic net metering is available up to your sanctioned load, commonly to 10 kW, under OERC rules. Confirm current terms with your local Tata Power DISCOM, since procedures are periodically updated.
Tariffs and typical savings
The Odisha regulator (OERC) retained existing tariffs for FY 2025-26, so domestic rates held steady, with higher slabs near ₹6 per unit. That stability makes payback estimates a little more reliable than in states seeing frequent revisions. Coastal and inland Odisha both get solid sunshine outside the monsoon months, and a rooftop array typically yields about 4.0 units per kW per day, roughly 1,460 units per kW a year. Feed your bill into our solar savings calculator for a quick size estimate, then refine panels to your roof with the system size calculator.
How PM Surya Ghar applies
PM Surya Ghar: Muft Bijli Yojana pays ₹30,000 per kW for the first 2 kW and ₹18,000 more for the 3rd kW, capping central support at ₹78,000 for 3 kW and above, with net metering to 10 kW. Payment comes by DBT after commissioning and inspection, and the balance can be financed with a collateral-free loan around 7 percent - estimate EMIs in the solar loan EMI calculator. Odisha also runs rural and farm solarisation efforts under the KUSUM umbrella, but for a household roof the central scheme above is the primary support to plan around.
A worked example
Take a 3 kW system in Bhubaneswar. At 4.0 units per kW per day it may generate about 4,400 units a year, worth close to ₹26,000 at around ₹6 per unit. With central support of ₹78,000 cutting a gross cost near ₹1.7 lakh to under ₹1 lakh net, payback typically falls in the region of three to four years. These figures are for planning only - monsoon cloud cover, shading and your usage pattern all shift the result. For a battery-free layout see the on-grid solar calculator, or benchmark against the India solar calculator.

How Odisha compares
Odisha ranks #26 of 36 states and union territories for output per kW: 1,445 units a year, 3% below the middle state (1,495). The range runs from 1,150 in Sikkim to 1,939 in Ladakh — see the full state ranking.

Frequently asked questions
No separate per-kW state capital subsidy is confirmed active for Odisha in 2025-26; the central PM Surya Ghar amount of up to ₹78,000 for 3 kW and above is the main benefit. TPCODL has, however, waived net-metering fees. Check current terms with your Tata Power DISCOM.
TPCODL covers central Odisha around Bhubaneswar and Cuttack, TPWODL the west, TPSODL the south and TPNODL the north. Your address decides which handles your net-metering connection, usually up to 10 kW for homes.
No. The OERC retained existing tariffs for FY 2025-26, so domestic rates held steady with higher slabs near ₹6 per unit. Rooftop solar still offsets those upper-slab units.
At about 4.0 units per kW per day a 3 kW system may make around 4,400 units a year, worth close to ₹26,000 at roughly ₹6 per unit, though monsoon cloud cover, shading and usage patterns change actual output.
