Morbi, the small town in Gujarat’s Rajkot belt, quietly produces nearly 70% of India’s ceramic tiles and sanitaryware — a cluster of more than 1,000 factories firing kilns 24×7 and consuming between 5 lakh and 50 lakh kWh (kilowatt-hours) per month each. In 2026, with PGVCL (Paschim Gujarat Vij Company Limited) HT (High-Tension) industrial tariffs sitting at ₹8–10 per kWh plus demand charges, a 1 MW (Megawatt) rooftop solar plant at a Morbi ceramic factory pays back inside 3.5–4 years after Accelerated Depreciation (AD), and an upsized 2–5 MW captive plant becomes the single highest-ROI capex any tile manufacturer can sign in the current cycle.
This guide is written for the promoter, plant manager, or finance head of a Morbi ceramic unit who is comparing solar quotes today and wants the actual numbers — 1 MW economics, group captive scaling, PGVCL net-metering versus net-billing, AD math, the design changes a Morbi shed needs because of kiln heat and grinding dust, and the rejection patterns that kill ROI when an installer treats Morbi like any other industrial site.
Direct answer. A 1 MW solar plant at a Morbi ceramic factory costs ₹3.5–4 crore CAPEX in 2026, generates ~16 lakh kWh/year, saves ₹1.1–1.4 crore in annual electricity bills at PGVCL HT tariffs, and pays back in 3.5–4 years after claiming 40% AD in Year 1. Scaling to 2 MW saves ₹2.4–2.8 crore/year, and a Morbi consortium pooling 5–10 MW under the group captive structure unlocks an additional ₹2–3/kWh tariff edge. Heaven Green Energy has commissioned solar at 50+ Morbi ceramic units.
If you are weighing the move now, the rest of this guide gives you the load profile, the cost-versus-savings spread for 1 MW and 2 MW, the PGVCL net metering rules above 500 kW, and the Morbi-specific design constraints — kiln heat zones, dust loading, 33 kV (kilovolt) HT connection — that decide whether your plant generates at name-plate or under-performs by 8–12%.
Why Morbi Ceramic Cluster Is India’s Top Industrial Solar Opportunity
Morbi is not a typical industrial estate. It is a single-product cluster where the energy bill is the second-largest line item after raw material — sometimes the largest in glazed wall tile and large-format slab units. A few structural facts make solar uniquely attractive here:
- Round-the-clock load. Tunnel kilns, spray dryers, and ball mills run continuously. There is no weekend dip in load — every solar kWh generated is consumed on-site, which means almost zero export and zero exposure to net-billing tariff loss.
- Massive roof area. A typical Morbi tile factory occupies 5–20 acres, with multiple shed roofs covering 60,000–2,00,000 sqft (square feet) — enough for 1–3 MWp (Megawatt-peak) of rooftop solar without any ground-mount land.
- High tariff. PGVCL HT-1 industrial energy charge sits at ₹8–10/kWh in 2026 per the GERC (Gujarat Electricity Regulatory Commission) tariff order, with demand charges of ₹250–₹360 per kVA (kilovolt-ampere) layered on top.
- Policy tailwind. The Gujarat Solar Policy 2024 published via GEDA (Gujarat Energy Development Agency) permits captive, third-party-sale, and group captive structures with simplified open-access charges for renewable energy.
The combination — high tariff, 24×7 load, big roof, supportive policy — does not exist together in any other Indian cluster at this scale. For a structural primer on the broader category, our industrial solar installation guide lays out the engineering and approval workflow that applies to any ≥500 kW project.
The 5-Stage Morbi Ceramic Solar Implementation Funnel
This is the framework we run for every Morbi ceramic project — from a glazed wall tile unit on the NH-8A bypass to a vitrified slab plant in the Lalpar belt. The 5-Stage Morbi Ceramic Solar Implementation Funnel sequences the decisions so that engineering, finance, and PGVCL approvals close in parallel rather than serially, compressing the project from a 9-month default to 5–6 months.
| Stage | Owner | Output | Typical duration |
|---|---|---|---|
| 1. Energy audit & load profile | EPC + plant electrical | 12-month kWh, kVA, time-of-day curve | 7–10 days |
| 2. Sizing & DCR + ALMM check | EPC engineering | DPR with module BOM, inverter layout, single-line diagram | 10–14 days |
| 3. Financing structure (CAPEX / OPEX / Group Captive) | CFO + EPC + lender | Term sheet signed, AD modelled | 15–25 days |
| 4. Installation + HT interface | EPC + PGVCL liaison | Plant erected, 33 kV / 11 kV switchgear tied in | 90–120 days |
| 5. Commissioning + AMC | EPC + plant ops | PGVCL synchronisation, net-meter / net-billing meter sealed, AMC live | 20–30 days |
Stage 1: Energy Audit & Load Profile
Pull 12 months of PGVCL bills, the SCADA (Supervisory Control And Data Acquisition) log if the factory has one, and the kiln-by-kiln consumption sheet. The output is a half-hour load curve that tells you exactly what fraction of plant consumption coincides with solar generating hours (typically 38–45% for a Morbi factory because kilns run 24×7 but spray dryers and ball mills peak 9 am–5 pm).
Stage 2: Sizing & DCR + ALMM Check
Size to 45–55% of average daytime load — this keeps export at zero and avoids any net-billing exposure. Confirm modules are on the current ALMM (Approved List of Models and Manufacturers) Tier-1 list and DCM (Domestic Content Manufacturing) compliance is documented if you intend to claim any state-level capital subsidy.
Stage 3: Financing Structure
Three live options in 2026 for a Morbi ceramic unit — CAPEX with AD 40%, OPEX (PPA — Power Purchase Agreement), and Group Captive. We compare these in §CAPEX vs OPEX below; for the broader decision frame read OPEX vs CAPEX — which is better in 2026.
Stage 4: Installation + HT Interface
For systems above 100 kW, the AC (Alternating Current) interconnection is via 11 kV or 33 kV HT switchgear, not LT (Low-Tension). This needs a HT panel, VCB (Vacuum Circuit Breaker), and a dedicated CT-PT (Current Transformer–Potential Transformer) metering cubicle approved by the PGVCL technical wing.
Stage 5: Commissioning + AMC
Synchronisation testing with PGVCL, net-meter or net-billing meter sealing, and a signed AMC (Annual Maintenance Contract) covering weekly cleaning (mandatory for Morbi because of grinding-silo dust drift) and quarterly thermal-imaging inverter checks.
Ceramic Factory Load Profile — Kilns + Dryers + Compressors
A solar plant is sized to consumption, not roof area. Understanding the Morbi tile-factory load mix decides where the solar plant connects on the LT/HT bus and how much of the bill the panels actually offset.
| Load category | Share of total kWh | Daytime overlap with solar | Notes |
|---|---|---|---|
| Tunnel kiln (firing) | 30–40% | High — 24×7 | Largely electrical for auxiliaries; gas-fired kiln body |
| Spray dryers | 15–20% | High — day shift heavy | Atomiser, blowers, slurry pumps |
| Ball mills & grinders | 12–18% | Medium | Batch process; runs 6 am–8 pm typically |
| Compressors (pneumatic) | 8–12% | High | Continuous |
| Glaze line + printing | 6–10% | High | Day shifts |
| Cooling tower + utilities | 5–8% | Medium | 24×7 |
| Lighting + HVAC (offices) | 3–5% | High | Day shifts |
For a 25 lakh kWh/month plant, ~12–14 lakh kWh land in the 8 am–5 pm window — comfortably enough to absorb a 1 MW solar plant generating ~5,000–5,500 kWh/day without any export. This is why Morbi ceramic ROI is so strong: every solar kWh displaces a ₹8–10 grid kWh, not a ₹3–4 export tariff.

1 MW Solar Math — Cost, Subsidy, AD, ROI
The 1 MW number is the planning anchor most Morbi factories start with — it fits a typical single-shed roof footprint of ~80,000 sqft, sits below the 500 kW net-metering ceiling for the export-cap conversation, and lands inside the ₹4 crore range where AD economics work hardest.
| Line item | 1 MW CAPEX | 2 MW CAPEX |
|---|---|---|
| All-in EPC cost (modules, inverter, BOS, HT panel, installation) | ₹3.5–4.0 crore | ₹6.5–7.5 crore |
| Annual generation (Morbi 5.4 PSH avg) | 15.5–16.5 lakh kWh | 31–33 lakh kWh |
| Effective PGVCL HT blended tariff offset | ₹8.5/kWh | ₹8.5/kWh |
| Gross annual savings | ₹1.32–1.40 crore | ₹2.64–2.80 crore |
| Year-1 AD benefit (40% on CAPEX × 25% tax) | ₹35–40 lakh | ₹65–75 lakh |
| Net Year-1 cash impact | ₹1.67–1.80 crore | ₹3.29–3.55 crore |
| Simple payback (post AD) | 3.5–4 years | 3.5–4 years |
| 25-year savings (post-degradation) | ₹28–32 crore | ₹56–64 crore |
Assumptions: Morbi 5.4 PSH (Peak Sun Hours)/day average, 77% performance ratio, 0.5%/year module degradation, blended HT tariff of ₹8.50/kWh post fixed-charge adjustment, 25% effective corporate tax. AD is claimed at 40% in Year 1 + remaining over Year 2–5 per Income Tax Act §32. For the full AD playbook including the conditions and Form 3CD reporting, read accelerated depreciation on solar tax.

Scaling Up to 2-5 MW with Group Captive Structure
When a single ceramic unit has a 5–10 MVA (Megavolt-ampere) sanctioned load and 50+ lakh kWh/month consumption, a 2 MW rooftop is the natural ceiling for the roof footprint — but the underlying tariff opportunity scales further. This is where Group Captive becomes the next move.
Under the Electricity Rules 2005 and the MNRE (Ministry of New and Renewable Energy) framework, two or more industrial consumers can hold ≥26% equity in a Special Purpose Vehicle (SPV) that owns a solar plant, with 51%+ of generation consumed by the equity-holding consumers. Applied to Morbi:
- A consortium of 4–6 ceramic factories pools 5–10 MW of solar capacity at a ground-mount site outside Morbi or at a shared roof aggregate.
- The SPV signs a Power Purchase Agreement (PPA) with the off-takers at ~₹3.5–4.5/kWh including open-access charges.
- Against the ₹8–10/kWh PGVCL grid tariff, the tariff edge is ₹3–4.5/kWh — roughly ₹4–6 crore/year saving per MW pooled.
The catch: open-access wheeling charges, cross-subsidy surcharge (CSS), and Additional Surcharge (AS) levied under the GERC open-access regulations have to be modelled correctly. For the full group captive structure, equity rules, and pitfalls, read group captive detailed 2026.
Morbi-Specific Design — Heat, Dust, High-Voltage Connection
Morbi is not the same engineering site as a textile mill in Surat or a pharma plant in Ahmedabad. Three constraints reshape the design:
Design tip
Locate the inverter room at least 25 metres from the kiln stack and roof exhaust ducts. Roof-top ambient temperature near kiln vents can hit 55–60 °C, which de-rates a standard IP65 inverter by 8–10% on a sustained basis. Either pull the inverter to a shaded utility shed or specify an IP66-rated, climate-controlled string inverter cabinet.
Heat de-rating. Module surface temperature in Morbi peaks above 65 °C in May–June even before kiln exhaust drift. Specify modules with a temperature coefficient ≤ −0.34%/°C and inverters rated for 50 °C continuous operation, not the default 45 °C.
Dust loading from grinding silos. Ball-mill exhaust and raw-material silos deposit fine alumino-silicate dust on roof modules — soiling losses run 12–18% within a fortnight if left untreated. The AMC must include weekly water-jet cleaning for the modules within 100 m of any silo line. Budget AMC at ₹1.2–1.5 lakh per MW per year for Morbi (versus ₹70,000–₹90,000 for a cleaner site).
33 kV / 11 kV HT interconnection. Above 100 kW the AC interconnect is HT. PGVCL specifies the metering CT-PT class, the VCB rating, and the synchronisation relay model. The HT panel adds ₹18–25 lakh to the BOS budget for 1 MW — installers who quote LT panels are under-scoping the project.
⚠️ Watch out
Some EPCs quote a flat per-watt rate (e.g., ₹35–₹38/Wp) that excludes the HT panel, dedicated 11 kV transformer, and PGVCL synchronisation hardware. For a Morbi 1 MW project these line items together add ₹35–55 lakh. Insist on an all-in CAPEX figure with HT scope itemised — anything else compares incorrectly to genuine all-in quotes.
PGVCL Net Metering for 1 MW+ Industrial
PGVCL operates under the GERC Net Metering Rooftop Solar PV Grid Interactive Systems Regulations (2016 with 2021 and 2023 amendments). The thresholds matter for any Morbi factory sizing above 500 kW:
| Capacity bracket | Mechanism | Settlement basis |
|---|---|---|
| Up to 500 kW (HT consumer) | Net Metering (NMM) | Unit-for-unit netting; surplus banked monthly, settled annually at APPC |
| 500 kW – 1 MW | Net Billing | Imported units billed at retail; exported units credited at APPC (~₹3.10–₹3.40/kWh) |
| Above 1 MW | Gross Metering or Captive | Full generation either sold to PGVCL at GERC-approved feed-in tariff, or treated as captive consumption |
For a Morbi 1 MW plant, the practical pattern is near-zero export captive consumption — size at 45–55% of daytime load, self-consume 100%, and treat it as a captive plant under the GERC Open Access regulations 2024. This avoids the entire net-billing tariff loss conversation. Above 1 MW, switch the conversation to group captive or third-party PPA.

Common Morbi Solar Installation Mistakes
Across the 50+ Morbi ceramic installations we have audited or retrofitted, six mistakes recur. Each one knocks 5–15% off the project IRR.
-
1
Sizing to roof area instead of daytime load. A 60,000 sqft roof can fit 800 kWp but if daytime load is only 600 kW, the extra 200 kW exports at net-billing rates and ruins ROI. Always size to consumption, not capacity.
-
2
Ignoring kiln-exhaust drift. Modules placed downwind of a tunnel-kiln stack lose 6–9% to soiling and heat de-rating. The structure layout has to factor wind-rose data from the IMD Rajkot station.
-
3
Skipping the HT scope in the quote. Comparing a quote that excludes the 11 kV panel against an all-in quote is a ₹25–40 lakh apples-to-oranges error. Demand single-line diagrams and HT BOQ (Bill of Quantities) before signing.
-
4
Choosing the wrong roof for primary mount. Older asbestos sheets and corroded GI sheets cannot carry the structural load and corrosion-creep voids module warranty. Audit the roof first; replace before mounting.
-
5
Under-budgeting AMC. A Morbi plant needs weekly cleaning, not monthly. AMC under ₹1 lakh per MW per year cannot meet that frequency, and modules drift to 15%+ soiling loss within a quarter.
-
6
Missing the AD claim window. Accelerated Depreciation at 40% must be claimed in the Year-1 ITR (Income Tax Return) for the year of commissioning. Plants commissioned in late March give finance teams two weeks of paperwork — a single missed Form 3CD entry can defer ₹35–40 lakh of cash benefit.
CAPEX vs OPEX for Morbi Ceramic
The financing decision is rarely a one-way answer. For Morbi units, here is how the trade-off actually sits in 2026.
- + 40% AD Year-1 — ₹35–40 lakh per crore invested
- + Levelised generation cost ₹2.2–2.6/kWh vs ₹8.5 grid
- + Full 25-year savings stack accrue to plant owner
- + Asset on balance sheet — ESG and bank covenant positive
- − Upfront ₹3.5–4 crore per MW
- − Owner carries O&M and performance risk
- + Zero CAPEX — savings from Day 1
- + Developer carries O&M and degradation risk
- + PPA tariff fixed at ₹3.8–4.5/kWh for 15–25 years
- − No AD benefit accrues to the factory
- − Long-term tariff escalator (2–3%/yr) in most PPAs
- − Lock-in 15–25 years; early termination penalties
Verdict. For a profitable Morbi ceramic unit with stable PAT (Profit After Tax) and balance-sheet headroom, CAPEX wins by 25–30% on NPV (Net Present Value) because the AD plus full savings retention outweigh the upfront drag. OPEX is the right answer only when the factory needs to preserve cash for a kiln expansion or has limited current-year tax liability to absorb the AD. The group captive route — where the factory takes equity in an off-site SPV — sits between the two on NPV and is the dominant answer for 5+ MW pooled across 4+ factories.

Frequently Asked Questions
How much does a 1 MW solar plant cost at a Morbi ceramic factory in 2026?
A 1 MW rooftop solar plant at a Morbi ceramic factory costs ₹3.5–4 crore all-in in 2026, including Tier-1 ALMM modules, string or central inverters rated for 50 °C, mounting structure on existing shed roofs, the 11 kV HT panel and VCB switchgear, PGVCL synchronisation hardware, and commissioning. The annual generation works out to 15.5–16.5 lakh kWh given Morbi’s 5.4 PSH daily average, saving ₹1.32–1.40 crore per year at the PGVCL HT blended tariff of ₹8.50/kWh and paying back in 3.5–4 years after the Year-1 AD benefit of ₹35–40 lakh is applied.
What is the payback period for solar at a Morbi ceramic factory?
Payback is 3.5–4 years for a CAPEX-financed 1 MW or 2 MW plant after claiming 40% Accelerated Depreciation in Year 1. Without AD, payback drifts to 4.5–5 years. Under an OPEX (PPA) structure, the factory sees zero upfront cost but the lifetime savings net of the PPA tariff (~₹4/kWh) come out 25–30% lower than CAPEX over 25 years. Group captive structures over 5–10 MW pooled across 4+ factories deliver the strongest IRR (Internal Rate of Return) — typically 22–28% post-tax.
Can Morbi ceramic factories use net metering under PGVCL for 1 MW solar?
Net metering under PGVCL is capped at 500 kW for HT consumers per the GERC net metering regulations. Above 500 kW, the mechanism shifts to net-billing — imported units at retail tariff, exported units credited at the Average Power Purchase Cost (~₹3.10–₹3.40/kWh). For 1 MW+ ceramic plants, the practical answer is to size the plant at 45–55% of daytime load and self-consume 100%, treating it as a captive plant under GERC open-access regulations 2024. This avoids any net-billing tariff loss.
How does the kiln heat at Morbi affect solar panel and inverter performance?
Roof ambient temperature near tunnel-kiln stacks reaches 55–60 °C during summer in Morbi. Standard modules de-rate at 0.35–0.45% per °C above 25 °C, so module yield can drop 8–12% in zones close to kiln vents. Inverters rated for 45 °C ambient lose efficiency further. The Morbi-specific design fix is to specify modules with a temperature coefficient ≤ −0.34%/°C, inverters rated for 50 °C continuous operation, and to locate the inverter room at least 25 metres from kiln exhaust ducts in a shaded utility shed.
What is the dust impact from grinding silos on Morbi rooftop solar?
Alumino-silicate dust from ball mills and raw-material grinding silos drifts onto rooftop modules across the Morbi cluster. Soiling losses run 12–18% within a fortnight on modules within 100 metres of any silo line, versus 3–5% at a cleaner industrial site. The AMC scope must include weekly water-jet cleaning — not the monthly cleaning standard at non-ceramic sites — which budgets ₹1.2–1.5 lakh per MW per year. Modules with anti-soiling coating reduce the burden but do not replace the cleaning frequency.
Is group captive solar viable for Morbi ceramic cluster?
Yes — group captive is the highest-IRR structure for Morbi when 4–6 ceramic factories pool 5–10 MW of off-site solar capacity. Under the Electricity Rules 2005, the consortium holds ≥26% equity in an SPV (Special Purpose Vehicle) that owns the plant, with 51%+ of generation consumed by the equity-holding members. Against a PGVCL HT tariff of ₹8–10/kWh, the all-in delivered cost (PPA + open-access charges + cross-subsidy surcharge) lands at ₹4.5–5.5/kWh, delivering ₹3–4.5/kWh tariff savings. Open-access wheeling and surcharge modelling under the GERC open-access regulations 2024 is the make-or-break of the deal.
What HT interconnection does PGVCL require for 1 MW solar at a Morbi factory?
For systems above 100 kW, the AC interconnection is HT at 11 kV or 33 kV depending on the factory’s existing supply voltage. PGVCL specifies the CT-PT metering class (0.2S typically), VCB rating, synchronisation relay model, and dedicated metering cubicle. The HT panel and switchgear add ₹18–25 lakh to the BOS budget for a 1 MW plant. PGVCL also requires a synchronisation test witnessed by their technical wing before final commissioning is approved and the plant is energised.
How long does a 1 MW Morbi ceramic solar project take from order to commissioning?
A clean 1 MW Morbi ceramic project runs 5–6 months from order to commissioning under the 5-Stage Morbi Ceramic Solar Implementation Funnel. Energy audit and DPR closes in 3 weeks, financing structure in 3–4 weeks (parallel to engineering), installation in 90–120 days, and PGVCL synchronisation + meter sealing in 20–30 days. The critical-path item is usually the PGVCL HT interconnection approval — submitting the single-line diagram and synchronisation scheme to the PGVCL technical wing in Stage 2 saves 4–6 weeks at the back end.
Can a Morbi factory claim PM Suryaghar subsidy for industrial solar?
No — PM Suryaghar is a residential rooftop scheme only. Industrial and commercial consumers do not qualify for the ₹78,000 central subsidy. Morbi ceramic factories instead claim Accelerated Depreciation at 40% in Year 1 under §32 of the Income Tax Act, which delivers ₹35–40 lakh of cash benefit per crore of CAPEX in Year 1 alone. Some state-level capital subsidy windows under the Gujarat Industrial Policy may apply for MSME-classified units; eligibility is unit-specific and should be checked through GEDA at the DPR stage.
