Your load shape decides the project, not your industry.

Solar works differently in every industry.

01

Food, beverage and cold chain

Refrigeration and compressors draw hardest when it is hottest — which is when a solar plant produces most. The two curves move together, and they move together seasonally too: your peak production months are your peak generation months.

• The load matches the resource. Chillers, cold rooms and compressor houses run through the middle of the day. Solar offsets the units you buy most of, not the cheap night-time ones.
• Tin-shed roofs are ideal. Large, clear, structurally simple spans — most bottling and processing plants carry megawatt-scale potential overhead without needing any land at all.
• Brand owners now audit it. Global principals increasingly grade franchisee and co-packer carbon, so renewable share has moved from a nice-to-have to a scorecard line.

Where we have built: bottling, dairy and processing plants across India, Nepal and Africa — the deepest part of our portfolio and the sector we have been in longest.

02

Hospitals and healthcare

A hospital never switches off. HVAC, imaging and sterilisation give you a large, flat, predictable daytime base load — the easiest kind of load to size a plant against, because it does not move.

• Zero-capex fits the balance sheet. On the OPEX model the hospital invests nothing and buys power below the grid rate from day one. Capital stays in clinical equipment, where the board would rather it went.
• Carports earn twice. Visitor and staff parking becomes generating area and shaded parking at the same time — useful where the roof alone cannot carry the load.
• It is patient-facing. Unlike most infrastructure decisions, this one is visible from the car park and reportable to the board.

Where we have built: multiple campuses for a listed hospital group, repeat-ordered since 2016, every one on the zero-capex model.

03

Auto components and engineering

Machining, casting and paint shops draw heavy, steady power right through the shift. On one- and two-shift operations the generation window and the production window are close to the same hours.

• Power is a controllable conversion cost. In machining and casting it is one of the few large ones you can actually attack — and solar attacks it for twenty-five years, at a price fixed on day one.
• Your OEM is already asking. Scope 3 targets are cascading from global OEMs down to Tier 1 and Tier 2, and renewable share is starting to appear in RFQ scoring rather than just in sustainability reports.
• More area than you think. Industrial sheds plus employee parking usually give an auto plant meaningfully more generating real estate than a roof survey alone suggests.

Where we have built: the NCR auto belt — Manesar, Gurgaon, Bhiwadi and Barwala — including repeat orders from the same groups.

04

Pharma and chemicals

Clean-room HVAC and process utilities never stop, so the daytime base load is large and constant. The complication is rarely the load — it is that the roof is small relative to it, and that everything has to be documented.

• When the roof is too small, go off site. Open access and group captive supply multi-megawatt volumes with no on-site footprint at all — which is usually the only way to move the needle on a process plant's bill.
• Auditors are the real driver. EU and US buyers, and CSRD-style disclosure, are turning verified renewable supply into a commercial requirement rather than a reputational one.
• Compliance-grade execution. ISO 9001, 14001 and 45001 systems, HSE-first execution and complete documentation — because a plant that cannot be evidenced is no use to a regulated site.

Where we have built: process and manufacturing plants across 22 states, plus utility-scale generation for off-site supply.

05

Textiles

Spinning and weaving run close to continuous, and almost all of it is motor load — a high, flat demand where every daylight unit the roof makes is consumed instantly, with nothing exported and nothing banked.

• Self-consumption does the work. A flat load means the plant can be sized aggressively against daytime demand without settlement risk — the regime your state applies matters less when nothing leaves the site.
• Margins feel every paisa. Power is one of the largest conversion costs in the mill. A fixed solar tariff is a hedge on the input that moves most.
• The night shift needs a different answer. Open access or group captive supplies the hours the roof cannot — one contract, two sources.

What we check first: your shift pattern against the generation curve, and whether the sheds can carry modules or the plant belongs off site.

06

Chemicals and process industries

Continuous process loads run day and night and cannot tolerate interruption — which makes the question less about the roof and more about how much of a large, steady draw can be moved to a cheaper source without touching reliability.

• Solar rides on top, the grid stays underneath. A behind-the-meter plant displaces daytime units without ever being in the supply-security path — the process never depends on it.
• Multi-megawatt loads suit the park. At continuous-process scale, group captive from an off-site park usually moves more of the bill than any roof can.
• Compliance is watching. Chemicals sits squarely in the disclosure net — metered solar generation is auditable Scope 2 reduction, not an estimate.

What we check first: your sanctioned load and state surcharge position, because at this scale the open access arithmetic decides the structure.

07

Warehousing and logistics

The inverse problem: enormous roof, modest load. Lighting, sorting and some HVAC peak in daylight, but the roof could generate several times what the building uses — so the settlement regime, not the structure, decides the project.

• Size to the meter, not the roof. Where net billing pays little for exports, the right plant is smaller than the roof invites — we will say so.
• Sheeting is the real survey. Pre-engineered warehouse roofs vary widely in what they can carry for twenty-five years; the structural check comes before the yield model.
• The tenant question is standard here. Most warehousing is leased — the tenure-matched structures on our leased-premises page were written for exactly this.

What we check first: your export regime and remaining tenancy — the two things that decide whether this is a 40% roof or a 100% roof.

Not on this list? The question is the same one either way — send us twelve months of bills and we will tell you what your load shape can actually support, including when the answer is less than you hoped. For worked examples in two of these sectors, see the case studies.
