Shed-roof plants
Metal-sheet and RCC roof mounting with non-penetrative or sealed-penetration fixings, engineered for the sheet gauge and purlin spacing you actually have.
Solar solutions engineered around your load, your roof and your balance sheet
Grid-tied rooftops, hybrid systems with storage, ground-mount plants, commercial and industrial projects, and the long-term maintenance that keeps all of them performing.
01 — Rooftop solar
Grid-tied rooftop solar
The default answer for any building with a shade-free roof and a monthly bill above about ₹2,500. Your array powers the building first; the surplus goes to the DISCOM through a bi-directional meter and comes back as credit at night.
There is no battery, nothing to replace and almost nothing to maintain beyond cleaning. That simplicity is why grid-tied systems have the shortest payback of anything we build — and why we will always model this option first, even when you came asking for something more elaborate.
- 1 kW to 500 kW, single or three phase
- Mono PERC / N-type TOPCon modules
- String or micro inverters with MPPT
- Hot-dip galvanised or aluminium mounting
- Net-metering application & liaison
- PM Surya Ghar subsidy registration
- Earthing and lightning protection
- Mobile monitoring from day one
Best for: independent homes, villas, gated-community common areas, schools, colleges, offices, showrooms and any daytime-heavy load.
| System | Roof area | Annual units | Suits a bill of |
|---|---|---|---|
| 3 kW | ~240 sq ft | ~4,350 kWh | ₹2,500 – ₹3,500 |
| 5 kW | ~400 sq ft | ~7,250 kWh | ₹4,000 – ₹5,500 |
| 10 kW | ~800 sq ft | ~14,500 kWh | ₹8,000 – ₹11,000 |
| 50 kW | ~4,000 sq ft | ~72,500 kWh | ₹40,000 – ₹55,000 |
Indicative only, at 1,450 kWh per kW per year. Actual sizing follows your twelve-month consumption and shade profile.
02 — Off-grid & hybrid
Hybrid systems with battery storage
A hybrid inverter treats solar, wind, battery and grid as four inputs to one decision: what should power this building right now, at the lowest cost, without an interruption.
For sites where an outage is expensive — operation theatres, server rooms, cold chains, hospitality — storage is not a luxury. Configured properly it also displaces diesel, shaves the demand peaks that drive your maximum-demand charge, and lets you buy from the grid when it is cheapest.
- Lithium-iron-phosphate (LFP) banks with battery management, cycle-life warranty and safe thermal behaviour — not repurposed lead-acid.
- Uninterrupted changeover on critical circuits, fast enough that the equipment never notices the grid has gone.
- Genset displacement with clear numbers on litres and rupees avoided per month.
- True off-grid builds for farmhouses, tower sites and locations where extending the grid costs more than generating.
- Wind-ready — the same hybrid inverter accepts a small wind turbine input for round-the-clock generation.
03 — Utility scale
Ground-mount plants and solar parks
When the roof runs out or the load is large enough to justify land, the engineering shifts from mounting brackets to civil works, evacuation and wind loading. We build for that.
Ground-mount projects live or die on the studies done before anything is procured: soil bearing capacity, flood and drainage behaviour, row spacing against inter-row shading, module cleaning water logistics, and the distance and voltage of the evacuation route. We do those studies first and put them in the proposal.
- 100 kW to multi-MW captive plants
- Fixed-tilt, seasonal-tilt or single-axis tracker
- Pile-driven or concrete-pedestal foundations
- HT evacuation, transformer and switchgear
- Open access & group captive structuring
- SCADA, weather station, string monitoring
- Solar fencing and site security integration
- Land feasibility and title support
Feasibility first
Irradiation, terrain, soil, drainage and evacuation assessed before a single module is specified.
Bankable modelling
P50 / P90 generation estimates and a financial model your lender or board can actually review.
04 — Commercial & industrial
Solar for factories, warehouses and campuses
Industrial tariffs rise faster than residential ones, and industrial roofs are large, flat and unshaded. That combination makes C&I solar the most financially obvious project on most MSME balance sheets — and the most often deferred.
Elevated structures
Car parks, yards, effluent ponds and walkways generating overhead while the space below stays fully usable — and shaded.
Peak shaving & BESS
Storage sized against your maximum-demand profile, so the saving comes from demand charges as well as energy charges.
| Model | Who owns the plant | Your investment | Best when |
|---|---|---|---|
| CAPEX | You do, from day one | Full project cost, with accelerated depreciation benefit | You have the capital and want the full 25-year saving plus the asset on your books |
| OPEX / RESCO | SunX or a funding partner | Nil — you pay only for units generated, under a long-term PPA | Capital is committed elsewhere and you want a tariff below your DISCOM rate immediately |
| Deferred / blended | Transfers to you over the term | Part payment now, the rest through generation | You want ownership eventually but a softer first-year outflow |
| Group captive | A special-purpose vehicle you part-own | 26% equity in the generating company | Consumption is large enough to justify open access and cross-subsidy relief |
Model availability depends on project size, credit profile and DISCOM regulations current at the time of signing. We will tell you which options your project genuinely qualifies for.
05 — Operations & maintenance
O&M, monitoring and plant revival
A solar plant rarely fails outright. It fades — a soiled array here, a dead string there, an inverter derating in the heat — and unless somebody is watching the numbers, the first sign is a bill that stopped falling.
Our maintenance contracts are built around measurement. Every plant reports its performance ratio against the model we sold you, and every month you get that comparison in one page. We also take on plants built by others: a health check, a diagnosis, and a written revival plan with what it will cost to get the yield back.
- Scheduled cleaning every four to six weeks — Hyderabad dust alone can cost you 8–15% of annual yield.
- Electrical maintenance — torque checks, IR and insulation testing, connector and cable-gland inspection, earth-resistance verification.
- Thermal and string diagnostics to find hotspots, bypass-diode failures and micro-cracks before they spread.
- Remote monitoring with escalation — an alert reaches a human, not just a dashboard nobody opens.
- Warranty administration — we file and pursue module and inverter claims on your behalf.
- 48-hour breakdown attendance anywhere in Hyderabad city for plants under contract.
Also delivered by SunX
The smaller work that often comes with a project
Rarely the reason a client calls, frequently part of what we end up delivering.
Solar water pumping
AC and DC surface and submersible pump sets from 1 to 25 HP for farms, apartments and estates, with controller and dry-run protection.
Solar street & campus lighting
All-in-one and split LED luminaires with LFP batteries and dusk-to-dawn control for roads, layouts and industrial perimeters.
Solar fencing
Energiser-based perimeter fencing for farms, plants and ground-mount sites — a safe deterrent that runs without grid supply.
EV charging integration
AC chargers wired behind your solar and storage, so vehicles charge on self-generated units rather than peak-tariff grid power.
Storage retrofit
Adding an LFP bank and hybrid inverter to an existing grid-tied plant, giving you back-up without rebuilding the array.
Energy audit & advisory
Load profiling, tariff-slab analysis and a recommendation that occasionally concludes efficiency should come before generation.
