15kW Solar System in Hyderabad — Price & Commercial ROI Guide 2026
Large Factories · Hotels · Hospitals · IT Offices · 3-Phase Commercial
A 15kW solar system is ideal for high-consumption commercial premises in Hyderabad — hotels, hospitals, factories, and large IT offices. It generates 1,800–2,100 units per month and, for commercial entities, delivers payback in 4–5 years through electricity savings combined with 40% accelerated depreciation and GST input credit.

Subsidy for 15kW: The PM Surya Ghar (PMSG) central subsidy is capped at 3kW for residential consumers — maximum ₹78,000. A 15kW residential installation receives only ₹78,000 regardless of size. Commercial premises (businesses, hospitals, schools registered as entities) are not eligible for PMSG but gain superior financial benefits through 40% accelerated depreciation and GST ITC — see below.
15kW Solar System Price in Hyderabad — 2026 Breakdown
| Cost Component | Amount (INR) | Notes |
|---|---|---|
| Solar Panels (28–38 panels, Tier-1 ALMM) | ₹4,80,000–₹6,10,000 | Adani, Waaree, Vikram — 400W–540W each |
| On-Grid 3-Phase String Inverter (15kW) | ₹90,000–₹1,25,000 | Sungrow SG15RT, Growatt, Sofar — dual MPPT |
| Mounting Structure (GI / Aluminium) | ₹70,000–₹95,000 | Industrial-grade, wind-rated |
| DC/AC Wiring & Protection | ₹35,000–₹50,000 | DCDB, ACDB, SPD, cable trays, earthing |
| Installation Labour | ₹35,000–₹50,000 | 4–5 day installation, skilled team |
| DISCOM 3-Phase Net Meter & Approval | ₹10,000–₹15,000 | TSSPDCL / TSNPDCL commercial fees |
| GST (12% on all components) | ₹86,000–₹1,13,000 | 12% GST — claimable as ITC for registered businesses |
| Gross Total (before any benefits) | ₹8,06,000–₹10,58,000 | Typical range, all-inclusive |
| Less: PMSG Subsidy (residential only, 3kW cap) | — ₹78,000 | Residential only; no additional for remaining 12kW |
| Net Residential Cost | ₹7,28,000–₹9,80,000 | After ₹78K PMSG subsidy |
| Less: GST Input Tax Credit (commercial) | — ₹86,000–₹1,13,000 | Claim against output GST liability |
| Less: 40% Accelerated Depreciation saving (30% bracket) | — ₹96,700–₹1,27,000 | Year-1 tax saving = 40% × cost × 30% tax rate |
| Effective Commercial Net Cost | ≈ ₹5,90,000–₹8,18,000 | After GST ITC + depreciation (varies by tax bracket) |
Commercial advantage: GST-registered businesses recover the full 12% GST paid as input tax credit. Under Section 32 of the Income Tax Act, solar equipment qualifies for 40% accelerated depreciation in Year 1 — at a 30% tax bracket this saves approximately 12% of the system cost directly. Together, these two benefits reduce your effective 15kW system cost by ₹1.8–₹2.4 lakh compared to the gross price.

Frequently Asked Questions
What is the price of a 15kW solar system in Hyderabad in 2026?
₹8,06,000–₹10,58,000 gross (inclusive of 12% GST). Residential: deduct ₹78,000 PMSG subsidy → net ₹7.3L–₹9.8L. Commercial: deduct GST ITC (₹86K–₹1.13L) + 40% depreciation tax saving (₹97K–₹1.27L) → effective cost ₹5.9L–₹8.2L.
How much does a 15kW solar system generate per month in Hyderabad?
1,800–2,100 kWh per month (21,600–25,200 kWh/year) using Hyderabad's 5.5 peak sun hours per day. Sufficient for large hotels, hospital wards, factory production floors, or IT office buildings.
What commercial tax benefits does a 15kW system offer?
Two major benefits for GST-registered businesses: (1) GST Input Tax Credit — reclaim the full 12% GST paid (₹86,000–₹1,13,000 depending on system cost). (2) 40% accelerated depreciation under Section 32 IT Act — at a 30% tax bracket, this generates a Year-1 tax saving of approximately ₹96,700–₹1,27,000. Consult your CA for exact figures based on your tax position.
Does a 15kW system need a 3-phase electrical connection?
Yes. 15kW systems use 3-phase string inverters (e.g., Sungrow SG15RT) as standard. Sri Ishaan Solar verifies your existing connection type during the free site survey and manages the full 3-phase DISCOM commercial net metering application, including technical drawing submission and inspection coordination.
