Sized for larger rice mill clusters, cold storage warehouses, hospitals and colleges. Real numbers below: system cost, monthly generation, accelerated depreciation math, and payback — no subsidy assumed, because commercial connections don't get PM Surya Ghar.
Cost range reflects 2026 Indian commercial rooftop solar market rates (~₹40,000-70,000/kW, with larger systems costing less per kW). Roof type, structure (RCC vs tin shed), panel brand, and site access change the final number — confirmed only after a free site survey.
Larger rice mill operations or clusters of allied units sharing a sanctioned load — a 100kW array offsets a meaningful share of heavy milling, drying and polishing machinery.
Larger multi-chamber cold storage facilities with continuous compressor load — daytime solar generation directly offsets the most expensive peak-demand hours.
Multi-specialty hospitals and diagnostic centres with heavy daytime AC, imaging and lab equipment load — high, steady daytime consumption is ideal for solar offset.
Bigger campuses with hostels, labs and large terrace area — enough roof space to size a 100kW system while still leaving headroom for future expansion.
Illustrative numbers for a business currently paying a commercial electricity bill of roughly ₹1.1-1.3L/month with a ~100kW sanctioned load.
| System size | 100 kW |
| Estimated system cost | ₹42,00,000 |
| Monthly generation (120 units/kW/month) | 12,000 units |
| Monthly bill offset (@ ₹9/unit) | ₹1,08,000 |
| Annual electricity savings | ₹12,96,000 |
| First-year depreciation (40% of cost) | ₹16,80,000 |
| Illustrative tax saving @ 25% slab | ₹4,20,000 |
| Illustrative tax saving @ 30% slab | ₹5,04,000 |
| Simple payback (electricity savings only) | ~3.2 years |
* Illustrative only, not tax advice — depreciation math assumes the asset is put to use for 180+ days in the financial year (else only half the normal rate, 20%, applies in the year of purchase). Actual tax benefit depends on your entity's income, applicable surcharge/cess, and tax regime. Run your own numbers in the depreciation calculator →
Solar power-based devices are classified as a 40% WDV block of assets under Appendix I to the Income Tax Rules (Rule 5 read with Section 32(1)(ii)). A business can write off 40% of the system cost against taxable profit in year one — a real cash tax shield, not available on most other capital equipment.
Commercial and industrial DISCOM tariffs in Telangana run higher per unit than residential slabs. Every unit a rooftop system generates offsets a more expensive unit — so paper payback is faster than a similarly-sized residential system, even with zero subsidy.
Note: larger OPEX/PPA solar providers typically require ~500kW minimum connected load, and big EPC contractors focus on large industrial accounts — which leaves this 20-100kW CAPEX segment underserved in the Hyderabad market. That's exactly the gap Sri Ishaan Solar's commercial division was built to serve.
