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.
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.
What Commercial Systems Look Like — Solar Cubic Project Sizes
Solar Cubic has installed commercial and industrial rooftop systems across Hyderabad ranging from 10kW to 2.5MW. Typical commercial customers:
- Office buildings (IT companies, co-working spaces) — 25kW to 150kW. Consume heavily 9am–7pm, which aligns perfectly with solar peak generation hours. Near-perfect solar utilisation without large battery investment.
- Manufacturing units (Balanagar, Jeedimetla, Patancheru, Bollaram IDAH) — 100kW to 1MW. High daytime load, 3-phase supply, large roof areas. Best candidate for maximum ROI.
- Educational institutions (colleges, schools, coaching centres) — 25kW to 250kW. Day-time operations align with solar. AMC agreements ensure 25-year worry-free operation.
- Hotels and hospitality — 50kW to 300kW. High electricity cost per unit (commercial slab). Solar reduces common area bills significantly.
- Hospitals and healthcare — 25kW to 500kW. Typically opt for hybrid (battery backup) to ensure 24/7 uptime for critical equipment.
- Cold storage and warehousing (Shamshabad logistics zone) — 200kW to 2.5MW. Massive roof areas, continuous daytime refrigeration load. Some of the best commercial solar economics in Hyderabad.
What to Check Before Going Commercial Solar in Hyderabad
- Roof ownership and lease duration — If you're in a leased facility, ensure the lease term is at least 7–8 years remaining and get landlord consent in writing before the investment.
- Sanctioned load and TSSPDCL connection type — Your system capacity cannot exceed your sanctioned load. HT consumers (above 50kW) have separate rules. Solar Cubic will check this during the free site survey.
- Roof load-bearing capacity — 100kW of panels + mounting structure weighs 8,000–12,000 kg. Old factory roofs may need structural assessment before installation.
- Shadow analysis — Factory floors often have water towers, ventilation ducts, AC units on the roof. A shadow-free zone calculation determines actual usable area.
- Net metering feasibility — TSSPDCL commercial net metering has slightly different documentation requirements than residential. Solar Cubic handles all paperwork and TSSPDCL liaison.
- CA consultation on depreciation — Confirm that your business will have taxable profits in the year of installation to actually benefit from the accelerated depreciation. Your CA can model the exact benefit.
