Morbi in Gujarat is the world’s largest ceramic tiles manufacturing cluster, producing 70% of India’s tiles and exporting to 150+ countries (CEEW, 2024). The cluster employs over 8 lakh people across 800+ units — tunnel kilns, wall tile lines, floor tile lines, vitrified tile plants, and sanitaryware factories. Energy is the single largest cost driver after raw materials: a mid-sized kiln line consuming 15,000–25,000 kWh per day pays ₹8–₹12 lakh per month to UGVCL.
Yet solar adoption in Morbi ceramic units has lagged behind expectations. The common objections — “our kilns run on gas, not electricity,” “we work 24/7 so solar won’t help,” “we can’t afford the downtime for installation” — are mostly myths or manageable constraints when solar is designed correctly for the specific load profile of a ceramic plant.
Heaven Green Energy has installed solar at ceramic units in Morbi and the surrounding cluster — Wankaner, Halvad, Rajkot. This guide shares what works, what doesn’t, the actual numbers, and the framework for building your own business case.
Key takeaway. A Morbi ceramic unit with 500 kWp of rooftop solar on its warehouse and factory shed roofs saves ₹55–₹80 lakh per year on electricity at UGVCL’s HT industrial tariff of ₹7–₹9/kWh. With 40% Accelerated Depreciation in Year 1, the effective payback drops to 2.5–3.5 years. The key is targeting the electrical daytime load — motors, compressors, lighting, polishing lines — not the gas-fired kiln itself.
The Morbi Ceramic Industry Energy Profile
A ceramic plant’s total energy consumption splits into two distinct streams:
Thermal energy (gas): The tunnel kiln burns natural gas or LNG to fire tiles at 1,150–1,250°C. This is 50–70% of total energy cost and cannot be directly replaced by solar electricity without an expensive and technically complex electric kiln conversion.
Electrical energy: Motors (conveyor, press, polishing, glazing), compressed air systems, ball mills, lighting, spray drying, and office/admin loads. This accounts for 30–50% of total energy cost — the portion where solar has immediate impact.
For a unit consuming 25,000 kWh/day of electricity, solar targets the 10,000–15,000 kWh/day that runs during daylight hours. A 1 MW rooftop system generates 5,000–6,000 kWh/day in Morbi’s excellent solar irradiation conditions (5.7–6.0 kWh/m²/day peak sun hours, MNRE solar atlas).
The Heaven Green Morbi Solar-Fit Assessment
We use a four-step process called the Morbi Solar-Fit Assessment to evaluate solar viability at any ceramic plant. This process can be completed in one site visit.
Step 1 — Identify the electrical load footprint. Pull the last 12 months of electricity bills and the DISCOM-sanctioned contract demand. Identify peak daytime electrical consumption hours (typically 7 AM to 7 PM). For most ceramic plants, polishing and packaging lines run day shifts; ball mills, compressors, and conveyor motors run round the clock but at lower utilisation on night shifts.
Step 2 — Map the roof area. Factory sheds, warehouses, and storage areas in a ceramic plant often cover 30,000–80,000 m² of ground area. Even if 50% is kiln shed (high-temperature environment, unsuitable for panels above), the remaining warehouse, dispatch, and admin rooftops easily accommodate 500 kWp to 2 MWp. GI or MS sheet roofs on steel trusses are common — ideal for clamp-mounted solar structures.
Step 3 — Compute the solar potential. In Morbi, a 1 MWp system generates approximately 1,750–1,800 MWh/year (Bridge to India, 2025; specific yield for Gujarat’s Saurashtra region). Compare this to your annual daytime electrical consumption. If the system covers 40–70%, proceed to Step 4.
Step 4 — Build the financial case. Calculate simple payback using: (Total installed cost) ÷ (Annual electricity saving). Apply Accelerated Depreciation (40% Year 1) to find tax-adjusted payback. If payback ≤ 4 years, the project has a strong case. For most Morbi ceramic units at ₹7–₹9/kWh, payback is 2.5–3.5 years with AD.
Solar Cost Breakdown: 500 kWp Ceramic Factory
Installed cost for a 500 kWp solar system on a steel truss GI-sheet factory roof in Morbi (Q2 2026):
| Component | Cost per kWp | 500 kW total |
|---|---|---|
| Solar panels (540W TOPCon, ALMM) | ₹17,500 | ₹87,50,000 |
| 3-phase string inverters | ₹5,500 | ₹27,50,000 |
| Mounting structure (GI Z-brackets, MS purlin) | ₹3,500 | ₹17,50,000 |
| DC/AC cables | ₹2,500 | ₹12,50,000 |
| ACDB, DCDB, earthing, surge protection | ₹1,500 | ₹7,50,000 |
| Civil, purlin reinforcement, safety | ₹2,000 | ₹10,00,000 |
| Installation labour | ₹2,000 | ₹10,00,000 |
| Net metering, DISCOM permissions | ₹1,000 | ₹5,00,000 |
| Total installed | ₹35,500/kWp | ₹1,77,50,000 |
A 500 kWp system on a factory with steel-truss GI roofs requires approximately 10,000 m² of roof area (using 540W panels at 2.0 m²/panel with 20% clearance). Most medium-sized ceramic units in Morbi have this area available on warehouse and packaging sheds alone.
ROI Analysis: 500 kWp Morbi Ceramic Plant
Assuming ₹8/kWh average blended tariff, 5% annual tariff escalation, 0.45% panel degradation, 1,780 kWh/kWp/year specific yield:
| Year | Generation (kWh) | Electricity saving | AD tax saving (Yr 1 only) | Net cash flow |
|---|---|---|---|---|
| Year 1 | 8,90,000 | ₹71.2 lakh | ₹22 lakh | ₹93.2 lakh |
| Year 2 | 8,85,995 | ₹74.7 lakh | — | ₹74.7 lakh |
| Year 3 | 8,82,008 | ₹78.3 lakh | — | ₹78.3 lakh |
| Year 4 | 8,78,039 | ₹82.2 lakh | — | ₹82.2 lakh |
| Year 5 | 8,74,088 | ₹86.3 lakh | — | ₹86.3 lakh |
| 5-yr cumulative | ₹3.93 crore | ₹22 lakh | ₹4.15 crore |
Investment: ₹1.78 crore. Payback: 1.9 years (Year 1 AD + Year 2 savings). 25-year net return: ₹12–₹16 crore.
This is one of the strongest industrial solar ROI cases in India because Morbi ceramic units combine: high electricity tariffs, excellent solar irradiation, large flat or shallow-pitched metal-sheet rooftops, and significant Accelerated Depreciation benefit.
💰 Real numbers
A Morbi ceramic unit that delays solar installation by one year loses approximately ₹70–₹90 lakh in electricity savings plus ₹3–₹5 lakh in additional tariff hike exposure. Over five years, a 3-year delay costs more than the capital invested — making the "wait and watch" strategy deeply expensive. See why delaying solar installation costs industries more for the full compound-delay analysis.
Steel-Truss GI Roof Solar: Key Technical Considerations
Most Morbi ceramic factories have 20–40-year-old steel-truss roofs with GI or colour-coated sheets. Mounting solar on these roofs requires specific technical checks:
Structural capacity: Factory trusses are typically designed for the roof load plus wind load, not the additional dead load of solar panels (8–14 kg/m² depending on panel and mounting weight). Before installation, our structural engineer performs a truss capacity check. If trusses are undersized, we use lighter aluminium mounting systems that distribute load over more purlin points.
Roof sheet condition: GI sheets older than 15 years often have corrosion at lap joints. Installing solar on a roof that needs replacement in 3 years means double installation cost. Heaven Green’s site survey includes a GI sheet condition rating.
Thermal expansion: Metal-sheet roofs expand 20–30 mm over temperature changes from winter to summer in Gujarat. The mounting clamps must accommodate this movement to avoid stress on the solar panel frames. We use floating-clamp systems that allow 5–8 mm of lateral movement.
Dust accumulation: Morbi’s ceramic manufacturing environment generates significant tile dust. Solar panels in this environment can lose 4–8% of yield from soiling between washings (pvmagazine.com, 2024). A bi-weekly panel cleaning schedule (easily done with a soft mop and water) restores full output. We recommend installing a low-pressure water line along the roof edge for easy cleaning access.

Comparing Solar Options for Morbi Ceramic Units
| Option | Capacity | Capital cost | Annual saving | Payback |
|---|---|---|---|---|
| Warehouse rooftop only | 200 kWp | ₹72 lakh | ₹28 lakh | 2.6 yrs |
| Warehouse + factory shed | 500 kWp | ₹1.78 crore | ₹71 lakh | 2.5 yrs |
| All available roof area | 1,000 kWp | ₹3.5 crore | ₹1.42 crore | 2.5 yrs |
| Ground mount (if land available) | 1,000 kWp | ₹3.2 crore | ₹1.42 crore | 2.3 yrs |
Morbi units with land parcels adjacent to the plant should consider ground-mounted solar, which has lower installed cost than rooftop (fewer labour hours per MW) and allows maximum capacity without structural constraints. For ground-mount solar park details, see ground-mount solar park solutions.

Frequently Asked Questions
Does solar make sense for a ceramic plant that runs kilns on gas?
Yes. Solar targets your electrical load — motors, compressors, polishing lines, lighting — not the gas-fired kiln. For a typical Morbi ceramic unit, electricity accounts for 30–50% of total energy cost. Even if you can’t electrify the kiln, eliminating 40–60% of your electrical cost through solar saves ₹50–₹150 lakh per year depending on your plant size.
What is the typical electricity consumption of a Morbi tile unit?
A medium-sized wall tile line in Morbi consumes 15,000–25,000 kWh/day of electricity. A large vitrified tile plant can consume 40,000–80,000 kWh/day. Polishing lines, ball mills, press motors, and compressed air are the biggest consumers. Solar typically covers 30–50% of this daily electrical load, depending on plant size and available rooftop area.
Can solar be installed while the ceramic factory is running?
Yes. Rooftop solar installation causes no disruption to production floor operations below. The main interruptions are: one 30-minute planned shutdown to connect the solar inverter to the main electrical panel (done on a weekend or scheduled maintenance window), and the DISCOM net meter replacement (DISCOM-controlled, typically 1–2 hours). All other installation work happens on the rooftop, away from production.
What is the Accelerated Depreciation benefit for a ceramic industry solar installation?
Under Section 32 of the Income Tax Act, solar plants qualify for 40% Accelerated Depreciation in Year 1. For a ₹1.78 crore system at a ceramic unit with 25% corporate tax, the Year 1 AD generates approximately ₹17.8 lakh in tax savings (40% × ₹1.78 crore × 25% tax rate). This effectively reduces the net investment to ₹1.60 crore, cutting the payback period by 4–6 months.
How does UGVCL handle net metering for large industrial consumers in Morbi?
UGVCL processes industrial consumer net metering applications under its LT or HT net metering framework. For systems above 500 kW, open access rules apply under the Gujarat Electricity Regulatory Commission (GERC) framework rather than net metering. For systems 100–500 kW, rooftop solar net metering under UGVCL’s LT/HT solar tariff schedule applies. Heaven Green Energy handles the full UGVCL application process for Morbi area clients.
How often do solar panels need cleaning at a Morbi ceramic factory?
Due to tile dust in the atmosphere, panels at Morbi ceramic units typically need cleaning every 10–14 days during production periods. A standard soft-brush wash with water from a ground-level pump and flexible hose takes 45 minutes for 500 panels. Each cleaning restores 4–6% of lost output. Annual soiling loss without cleaning would be 8–15% of generation — worth ₹5–₹12 lakh on a 500 kWp system. We recommend including panel cleaning in the AMC contract.
What size solar system should a medium Morbi ceramic unit install?
A medium-sized ceramic unit consuming 15,000–20,000 kWh/day of electricity and operating 2 shifts (6 AM to 10 PM) has a daytime electrical load of approximately 10,000–14,000 kWh. A 500–700 kWp solar system covers 35–50% of this daytime load — the optimal sizing range that ensures high self-consumption without excessive export issues. Larger roof area allows scaling to 1 MWp for maximum savings.
Is ground-mount solar feasible for Morbi ceramic units?
If your plant has 1–2 acres of unused land (common near plant perimeters or adjacent to transit sheds), ground-mount solar is often more cost-effective than rooftop at scale. Ground-mount avoids structural concerns with old factory rooftops, allows optimal south-facing 15° tilt, and is easier to clean. Installed cost for ground-mount at 1 MWp scale in Morbi is approximately ₹3.2–₹3.5 crore versus ₹3.5–₹4 crore for rooftop of the same capacity.
