Commercial Solar ROI in Hyderabad: 40% Depreciation + Real Payback Numbers

Businesses in Hyderabad are sitting on one of the most compelling capital investments available: rooftop solar with 40% accelerated depreciation. The numbers are difficult to ignore — and most business owners have no idea this benefit exists.

The Two Ways Commercial Solar Saves Money

Residential solar has one financial driver: electricity bill savings. Commercial solar has two — and the second one is where the real ROI advantage comes from.

Driver 1: Electricity Bill Savings
Commercial and industrial consumers pay TSSPDCL tariffs of ₹5.20–₹9.95/unit (HT category). A 100kW system generating 1,30,000 units/year at ₹7/unit saves ₹9.1 lakh/year on the electricity bill.
Driver 2: Income Tax Depreciation
Solar energy equipment qualifies for 40% accelerated depreciation under Section 32 of the Income Tax Act. For a ₹50 lakh system, Year 1 depreciation of ₹20 lakh reduces taxable income — saving ₹6–7 lakh in tax immediately.

Combined, these two streams make commercial solar in Hyderabad one of the few capital investments with a sub-3-year payback that also produces ongoing returns for 25+ years.

The 40% Accelerated Depreciation Explained

Under the Income Tax Act, Section 32 allows businesses to claim depreciation on assets used for generating electricity. Solar panels and inverters fall under "solar power generating plants and equipment." The allowed depreciation rate is 40% per year on a Written Down Value (WDV) basis.

How WDV Depreciation Works for Solar

Say your company installs a 150kW solar system for ₹75 lakh (all-inclusive) in FY 2025-26:

Year Opening WDV Depreciation (40%) Tax Saved (30% bracket) Closing WDV
Year 1 ★ ₹75,00,000 ₹30,00,000 ₹9,00,000 ₹45,00,000
Year 2 ₹45,00,000 ₹18,00,000 ₹5,40,000 ₹27,00,000
Year 3 ₹27,00,000 ₹10,80,000 ₹3,24,000 ₹16,20,000
Years 4–5 Depreciation continues on reducing balance… Declining
Total Tax Saved (5 yrs) ~₹19–21 lakh

Important: Depreciation can only be claimed if the business has taxable profits. If a business is in a loss position, the depreciation benefit gets deferred. Consult a Chartered Accountant to confirm the benefit applies to your company's tax position before factoring it into ROI calculations.

Complete ROI Example: 100kW Factory Rooftop — Balanagar, Hyderabad

A manufacturing unit in Balanagar with a 5,000 sq ft south-facing factory roof installs a 100kW on-grid rooftop solar system:

Parameter Value
System size 100 kW
System cost (all-inclusive) ₹48–55 lakh
Annual generation 1,40,000–1,50,000 units/yr
TSSPDCL LT tariff avoided ₹6.50–8.50/unit (commercial slab)
Annual electricity saving ₹9.5–12 lakh/year
Year 1 depreciation tax saving ₹6–8 lakh (at 30% tax rate)
Effective Year 1 total return ₹15–20 lakh
Effective payback period 2.5–3.5 years
25-year total savings ₹1.8–2.5 crore (electricity alone)

Based on Hyderabad commercial electricity tariff and actual Solar Cubic project data. Savings increase if TSSPDCL tariffs rise — which historical data confirms they do, 5–8% per year on average.

Tariff Escalation: Why Solar Gets More Valuable Every Year

TSSPDCL commercial tariffs have increased by an average of 5–8% per year over the past decade. A business locked in a solar system at 2026 installation cost benefits doubly — the system cost is fixed while the value of each avoided unit keeps increasing.

A factory consuming 1 lakh units/month paying ₹7/unit today will likely be paying ₹11–13/unit in 2036 if historical trends hold. The same solar system that saves ₹10 lakh/year in 2026 will be saving ₹17–20 lakh/year in 2036 — with zero additional capital outlay.
