Solar for Hotels & Restaurants in Hyderabad 2026 — Cut Bills by ₹20K–₹1.5L/Month
Electricity is the second-largest operating cost for most hotels and restaurants in Hyderabad — after staff wages. Air conditioning, commercial kitchens, refrigeration banks, water heating, corridor lighting, laundry equipment, and POS systems run around the clock. A 30-room hotel in Secunderabad pays ₹60,000–₹90,000 per month in TSSPDCL bills. A full-service restaurant in Banjara Hills pays ₹25,000–₹60,000. A large banquet hall or resort can cross ₹1.5 lakh every month. Solar eliminates 60–80% of that cost, pays itself back in 4–5 years, and delivers 25 years of near-zero electricity costs. This guide covers system sizing, ROI, TSSPDCL net metering, backup needs, and why solar beats a diesel generator on every metric.
System Sizing by Hospitality Property Type
Electricity consumption in the hospitality sector varies significantly based on property type, AC load density, kitchen equipment, and occupancy. The table below maps common property types to typical monthly bills and the recommended solar system size:
| Property Type | Monthly Bill | Monthly Units | Recommended Solar |
|---|---|---|---|
| Tiffin centre / small café (no AC) | ₹10,000–₹20,000 | 1,000–2,000 units | 10kW–15kW |
| Standalone restaurant (with AC) | ₹25,000–₹55,000 | 2,500–5,500 units | 15kW–30kW |
| Guesthouse / lodge (10–20 rooms) | ₹20,000–₹45,000 | 2,000–4,500 units | 10kW–25kW |
| Mid-size hotel (30–50 rooms) | ₹50,000–₹90,000 | 5,000–9,000 units | 25kW–50kW |
| Large hotel / business hotel | ₹90,000–₹1,50,000 | 9,000–15,000 units | 50kW–80kW |
| Resort / banquet hall / convention centre | ₹1,00,000–₹1,50,000+ | 10,000–15,000+ units | 60kW–100kW+ |
Actual system size is constrained by available unshaded rooftop area. A 10kW system requires approximately 700–750 sq ft; a 50kW system needs 3,500–4,000 sq ft. We conduct a free site survey before recommending any system.
ROI Calculation — 15kW System for a Mid-Size Restaurant
The following example is based on a standalone restaurant in Hyderabad with a monthly electricity bill of approximately ₹35,000 and a commercial tariff of ₹8/unit:
| Item | Value |
|---|---|
| 15kW system gross cost | ₹7,25,000 |
| Monthly solar generation (Hyderabad average) | ~1,800 units |
| Commercial tariff (TSSPDCL LT-II commercial) | ₹8.00/unit |
| Monthly saving (1,800 units × ₹8) | ₹14,400 |
| Annual saving | ₹1,72,800 |
| Simple payback period | ~4.2 years |
| % of restaurant bill offset | ~41% |
| 25-year net savings (after capital cost, with 5% tariff escalation) | ₹25–30 lakh |
Savings assume 5% annual electricity tariff escalation and 0.5% annual panel degradation over 25 years. A larger system (25kW–50kW) proportionally scales savings. Actual ROI depends on your tariff slab, roof orientation, and shading.
Peak-load advantage for hospitality: Solar generation peaks between 9 AM and 4 PM — exactly when restaurants run breakfast and lunch services and hotels operate housekeeping, laundry, and kitchen. Direct self-consumption during these hours is the most efficient way to use solar, as you offset expensive grid units at your full commercial tariff rate without going through net metering.
No PMSG Subsidy — But Still Strong ROI
The PM Surya Ghar Muft Bijli Yojana (PMSG) subsidy — up to ₹78,000 for 3kW systems — applies exclusively to domestic (residential) electricity connections. Hotels, restaurants, lodges, and banquet halls operate on commercial Low-Tension (LT-III/LT-IV) or High-Tension connections and are not eligible for PMSG.
This does not diminish the financial case. Commercial and HT tariffs in Hyderabad are meaningfully higher than domestic rates:
| Connection Type | Typical Tariff (₹/unit) | PMSG Subsidy? | Solar ROI |
|---|---|---|---|
| Domestic (residential) | ₹2.80–₹5.00 | ✓ Yes (up to ₹78K) | Good (5–7 years payback) |
| LT Commercial (hotels, restaurants) | ₹7.50–₹9.00 | ❌ Not eligible | Excellent (3.5–5 yrs) |
| HT (large hotels, resorts above 75kW) | ₹6.50–₹8.50 | ❌ Not eligible | Excellent (4–5 yrs) |
Because commercial consumers pay more per unit, each solar unit generated saves more money. A 15kW system on a commercial connection saves ₹14,400/month at ₹8/unit. The same 15kW system on a domestic connection would save only ₹5,400/month at ₹3/unit — even with the subsidy included. The higher your commercial tariff, the faster solar pays back.
Why Solar Beats a Diesel Generator — by a Wide Margin
Most hotels and restaurants in Hyderabad already own or rent a diesel generator for backup power. Many properties run generators during the afternoon DISCOM load-shedding windows. Here is an honest cost comparison:
| Cost Factor | Diesel Generator | Solar System |
|---|---|---|
| Cost per unit generated | ₹18–₹25/unit | ₹0.50–₹1.50/unit (25-yr amortised) |
| Fuel dependency | High — diesel price fluctuates | None — free sunlight |
| Monthly fuel cost (10kW equivalent) | ₹15,000–₹25,000 | ₹0 |
| Annual maintenance | ₹20,000–₹50,000 (oil, filters, servicing) | ₹5,000–₹15,000 (optional AMC) |
| Noise / fumes | Significant — affects guest experience | None |
| Reduces DISCOM bill? | No | Yes — up to 80% |
| CO₂ emissions | High — 0.7 kg per unit | Zero during operation |
A restaurant already spending ₹18,000/month on generator diesel can pay for solar from that saved diesel cost alone. The solar system simultaneously eliminates the generator's running cost and slashes the DISCOM bill — a double saving. Properties that switch from diesel backup to a hybrid solar-plus-battery system typically see total energy cost reductions of 55–70%.
TSSPDCL Net Metering for Commercial Properties
Hotels and restaurants connected to TSSPDCL (Telangana Southern Power Distribution Company) can apply for rooftop solar net metering under the state's Renewable Energy Policy. Here is how the process works for commercial Low-Tension consumers:
- Feasibility assessment — a TGREDCO-registered installer (like Sri Ishaan Solar) inspects the site, measures available rooftop, checks sanctioned load, and determines the maximum permissible system size (typically up to 100% of sanctioned load for LT consumers)
- Application submission — the installer submits an application to the DISCOM's Electrical Sub-Division office with: project proposal, Single Line Diagram, load details, proof of ownership/occupancy, and last three months' electricity bills
- Technical sanction — TSSPDCL engineers inspect the site and issue a technical sanction letter, specifying panel capacity, inverter specifications, and metering arrangement (typically 30–45 days)
- Installation — Sri Ishaan Solar installs panels, mounting structure, inverter, and AC distribution board per the sanctioned design. Typical installation time: 5–10 working days for a 15kW–50kW system
- Net meter installation — after installation, TSSPDCL replaces the existing energy meter with a bi-directional net meter that records both import (from grid) and export (to grid) in separate registers
- Commissioning — the system is energised and connected to the grid under the net metering agreement. Surplus generation is credited to your account at the applicable rate
For High-Tension (HT) consumers — large hotels and resorts with a sanctioned load above 75kW — the net metering application routes through TSSPDCL's HT Division and involves a separate techno-commercial feasibility study. Timelines are 45–90 days. Sri Ishaan Solar handles the complete documentation and DISCOM liaison for both LT and HT properties.
Net metering economics for hospitality: Restaurants consume most power during daytime kitchen and service hours — meaning direct solar self-consumption is very high. Hotels consume heavily at night for room AC and lighting — meaning more surplus is exported to the grid during the day, and night import reduces. In both cases, the net meter ensures you only pay for the difference between what you drew and what you exported. Your annual bill can drop by 50–75% even if night consumption is high.
Backup & Hybrid Solar for Critical Hospitality Loads
For hotels and restaurants, certain loads simply cannot go down — even for 30 minutes. A power cut mid-service means cold food, stalled orders, disrupted check-ins, and unhappy guests. Standard on-grid solar systems shut down automatically during grid outages. For hospitality properties, we recommend hybrid solar systems with LFP battery backup for the following critical loads:
- Commercial kitchen — exhaust fans, cooking equipment starters, kitchen lighting
- Refrigeration — cold rooms, walk-in coolers, beverage refrigerators; a temperature rise of even 2–3°C over 30 minutes risks spoilage
- POS and billing terminals — tablet-based billing, receipt printers, card payment machines
- Front desk and check-in systems — hotel management software, IP phones, key card encoders
- Emergency lighting and exit signs — mandatory under fire safety norms, must function during outages
- CCTV and security systems — should not lose power during grid outages
| Property Type | Recommended Hybrid System | Battery Backup | System Cost (approx.) |
|---|---|---|---|
| Restaurant / café (critical loads only) | 10kW hybrid | 10kWh LFP | ₹5,50,000–₹6,50,000 |
| Restaurant (full critical + AC zones) | 15kW hybrid | 20kWh LFP | ₹9,50,000–₹11,50,000 |
| Guesthouse / lodge (10–20 rooms) | 15kW–20kW hybrid | 20kWh–30kWh LFP | ₹11,00,000–₹16,00,000 |
| Mid-size hotel (30–50 rooms) | 30kW–50kW hybrid | 40kWh–60kWh LFP | ₹22,00,000–₹38,00,000 |
LFP (Lithium Iron Phosphate) batteries are recommended for commercial use — 3,000–6,000 cycle life (8–15 years), no thermal runaway risk, and stable performance in Hyderabad's high ambient temperatures. Lead-acid batteries are not recommended for commercial backup due to short cycle life and high maintenance needs in hot climates.
A hybrid system eliminates both the DISCOM bill (through solar generation) and the generator running cost (through battery backup). Properties that previously ran a 15kVA diesel generator for 4–6 hours per day can completely decommission the generator — saving ₹15,000–₹25,000/month in diesel while improving guest comfort from reduced noise and fumes.
What Makes Hospitality Solar Different from Other Commercial Solar
Hotels and restaurants have specific requirements that a generic commercial solar installer may overlook. At Sri Ishaan Solar, our commercial hospitality assessments cover:
- Load profiling by hour — restaurant kitchen peaks, hotel breakfast peak, dinner service peak, and overnight hotel AC load are all different. We size storage and inverter capacity to match your specific demand curve, not just the monthly total
- Water heating integration — hotels with large hot water demand (rooms + kitchen) can save an additional ₹8,000–₹20,000/month by switching electric geysers to solar thermal + heat-pump hybrid, reducing electrical load before solar sizing
- Rooftop structural assessment — commercial kitchen exhaust ducts, cooling towers, AC outdoor units, and water tanks compete for rooftop space. We design the solar layout around existing infrastructure, not on top of it
- Phase balancing — most hospitality properties run three-phase connections. We ensure the solar inverter output is balanced across phases to avoid energy meter anomalies and DISCOM penalties
- Monsoon performance — Hyderabad receives 700–750mm of rain annually, concentrated June–September. A 15kW system still generates 900–1,100 units/month during monsoon (vs 1,800 in summer), which is factored into our 25-year ROI projections at actual Hyderabad irradiance data
