Solar EPC Company in India for Industrial Rooftop Projects
Tropical Solar is one of the solar EPC companies in India that takes your plant end to end — survey, design, supply, installation, DISCOM approvals and O&M under a single contract. With 200+ MWp commissioned across industrial rooftop, commercial and ground-mounted projects, Tropical Solar builds solar that generates what it was designed to.
Industrial and Commercial Solar — All Turnkey
If it needs solar, Tropical Solar can build it. We take complete turnkey responsibility for a project of any size, from a factory shed to a warehouse roof to an open-land plant, under one contract and one accountable team.
Industrial
Factories, warehouses and process plants with large roofs and heavy daytime load.
Commercial
Hotels, hospitals, malls, cold storage, campuses and offices on long daytime load curves.
Ground-Mounted
Open land, utility-scale and open-access plants where roof area runs out and acreage takes over.
Every Month Your Roof Stays Empty Costs You Money
Commercial and industrial power in India now lands between ₹8 and ₹12 a unit, and the tariff has moved one way for a decade. Solar generated on your own roof costs roughly ₹2.5 to ₹3.5 a unit over the life of the plant.
A 30,000 sq ft metal-sheet factory roof carries a 350–400 kW plant. In Indian conditions that produces about 5.5 lakh units a year — enough to cover 40–80% of a mid-size factory’s consumption, and roughly ₹25–35 lakh of electricity spend you are currently paying somebody else.
The roof is already there. The only question an experienced solar EPC company in India can answer for you is how much of that bill it can take out, and how fast.
Solar EPC Services Tropical Solar Delivers Across India
Unlike EPC solar companies that supply only modules or only labour, Tropical Solar delivers the whole plant. Two core offerings cover almost every project we build.
Commercial & Industrial Rooftop
Turn an empty factory or commercial roof into generation. Complete solar rooftop EPC for metal-sheet, RCC and standing-seam roofs, engineered to your load and sized to your net-metering limit.

Large-scale EPC solar power plants that deliver real impact. Topographical survey, foundations, mounting structures, evacuation and grid interconnection, built to perform at scale.
Get a QuoteThe Tropical Solar EPC Process, Stage by Stage
EPC stands for Engineering, Procurement and Construction — a single-responsibility contract. This is what solar EPC companies in India should cover, and exactly what Tropical Solar does on every project.
01. Site Survey & Feasibility
Roof measurement, shadow analysis, structural assessment, sanctioned-load check and a study of your existing electrical setup — before anybody quotes you a number.
02. Engineering & Design
Single-line diagrams, string layout, structure design, cable sizing and protection scheme, engineered for your specific roof and load profile rather than a standard template.
03. Procurement
Modules, inverters, mounting structure, cables, ACDB/DCDB and protection gear sourced to specification. The components are listed in your proposal, not left vague.
04. Construction & Installation
Civil and structural work, module mounting, DC and AC cabling, inverter and panel installation, earthing and lightning protection, executed by supervised Tropical Solar teams.
05. Approvals & Net Metering
DISCOM application, liaison, inspection coordination, net-metering sanction and commissioning paperwork — the stage that stalls most projects, handled by us.
06. Commissioning & O&M
Testing, performance validation, handover, then remote monitoring, module cleaning, preventive maintenance and warranty-claim support for the years that follow.
Industrial Solar Rooftop Systems for Factories
A factory roof is the cheapest land you will ever own. An industrial rooftop solar plant uses it to generate power at the point of consumption — no transmission loss, no wheeling charges, no land cost.
- Generation: 1,400–1,700 units per kW per year in Indian conditions, depending on location and tilt.
- Coverage: typically 40–80% of a mid-size plant’s annual consumption.
- Payback: usually 3–5 years, followed by roughly 20 years of near-free power.
- Tax: accelerated depreciation available on the plant under the CAPEX model.
- Roofs we work on: metal sheet, RCC, standing seam, north-light and asbestos replacement.
Every industrial rooftop solar power plant Tropical Solar builds starts with a structural assessment of the existing shed, because a roof that cannot carry the load safely is not a roof we will install on.
Commercial Rooftop Solar for Offices and Warehouses
Commercial buildings run long daytime load curves — exactly when solar generates. That makes hotels, hospitals, malls, cold storage, warehouses, IT parks and educational campuses some of the strongest candidates for rooftop solar in India.
- Daytime match: HVAC, lighting and refrigeration peak when the sun does.
- Cold storage & warehousing: large unshaded roofs over a continuous, predictable load.
- Hospitality & healthcare: round-the-clock operations with high fixed power cost.
- Campuses: multiple roofs that can be aggregated into one sanctioned plant.
Tropical Solar designs commercial systems around your sanctioned load and net-metering limits, so the plant is sized to what the meter and the regulation will actually allow.
Ground-Mounted and Utility-Scale Solar EPC
Where roof area runs out, land takes over. For developers, IPPs and industries with spare land or open-access ambitions, Tropical Solar works as one of the few solar EPC contractors in India delivering plants from survey through to grid interconnection.
- Site works: topographical survey, geotechnical investigation, land grading and levelling.
- Structures: fixed-tilt or tracker-based mounting with foundation design to soil conditions.
- Power systems: inverters, transformers, HT panels, protection, cabling and metering.
- Grid: evacuation design, interconnection and compliance facilitation.
- Long-term O&M: multi-year maintenance including vegetation control and thermography.
CAPEX or OPEX: Which Solar Model Suits You
This is the first question most finance teams ask, and the one most solar EPC companies in India answer last. Both models work — they simply suit different balance sheets, and Tropical Solar delivers either.
| CAPEX (you own it) | OPEX / RESCO (we own it) | |
|---|---|---|
| Upfront investment | Full project cost paid by you | Zero capital outlay |
| Who owns the plant | Your company, from day one | The developer, for the contract term |
| What you pay | One-time cost, then only O&M | A per-unit tariff below your grid rate |
| Tax benefit | Accelerated depreciation available | Not applicable to you |
| Savings over 25 years | Highest — you keep all of it | Lower, but immediate and risk-free |
| Best suited to | Profitable units with capital to deploy | Firms protecting cash flow or testing solar |
Tropical Solar will model both against your actual bill and show you the numbers side by side before you commit to either.
How Tropical Solar Protects Your Roof, Output and Approvals
Buyers rarely worry about solar in the abstract. They worry about three specific things, and how a solar EPC company in India answers them tells you more than any brochure.
Will my roof take the load, and will it leak?
Every project begins with a structural assessment of the existing shed or slab against the added dead and wind load. Mounting is designed to minimise penetrations, and every fixing point is sealed and treated to a defined waterproofing method. Where a roof is too old or too weak, Tropical Solar says so before quoting — not after the modules are up.
Will it generate what you promised?
Underperformance usually traces back to cheap modules, undersized cables, poor string design or no monitoring. We specify components in writing, simulate expected yield for your site, and hand over a monitored plant so generation can be checked against design — not taken on trust.
Who handles DISCOM and net metering?
Tropical Solar does. Application, liaison, inspection coordination and net-metering sanction sit inside our scope, because this is the stage where projects stall for months when it is left to the customer. You get a plant that is commissioned and metered, not one waiting on paperwork.
