We are technology-agnostic and brand-independent. Components are selected per project against degradation behaviour, warranty depth, service presence in Hyderabad and how they perform in 45 °C heat — not on distributor margin.
Product range
Filter by category to see what we specify, and the questions we ask before choosing between makes.
The current mainstream: high efficiency, well-understood degradation, and the deepest service and replacement network in India. Our default for cost-sensitive residential work.
Better low-light and high-temperature behaviour and a gentler degradation curve. Worth the premium where roof area is the binding constraint or ambient temperatures are extreme.
Glass-glass modules that harvest reflected light from the surface below. Genuinely useful on white-coated roofs, elevated structures and ground-mount with light ground cover.
The standard for grid-tied rooftops. We size the DC/AC ratio and string layout to your roof rather than accepting a default, which is where most of the avoidable loss hides.
One unit managing PV, wind, battery and grid with independent MPPT on each source. The heart of every hybrid system we build, and what makes a wind-plus-solar site practical.
Per-module conversion for roofs that are broken up, partly shaded or facing several directions. More expensive per watt, but it recovers yield a string design would lose.
Lithium-iron-phosphate is our default chemistry: safer thermal behaviour than NMC, thousands of cycles, and no maintenance. Sized against the loads you actually need to carry.
Containerised or cabinet storage for peak shaving, demand-charge management and genset displacement, with the control logic tuned to your tariff structure.
Omnidirectional rotors for rooftops and built-up sites. They tolerate turbulent, shifting urban airflow far better than a bladed machine that has to yaw into the wind.
Three-blade machines on guyed or free-standing masts for open sites. Higher yield per kW than any rooftop unit — provided you have the land and the height.
Structure is where cheap systems fail first. We specify hot-dip galvanised steel or anodised aluminium designed for the wind zone, and we torque and record every fastening.
Purpose-built canopies that generate above while the yard, parking or walkway below stays fully usable — with proper drainage and clearance designed in.
The unglamorous part that decides whether your plant survives a Hyderabad pre-monsoon storm: proper DC and AC protection, surge devices, earthing and lightning arrest.
UV-stable, double-insulated solar DC cable sized for voltage drop rather than minimum ampacity, routed in conduit and cable tray so nothing bakes on a hot roof.
Generation, consumption and export visible on your phone, with alerting when output drifts from the model. On larger plants, string-level data and a weather station.
No products in that category yet — ask us and we will source it.
Reference sizing
A starting point for conversations, not a quotation. Your proposal is built from your bill, roof and load profile.
| Application | PV | Inverter | Storage | Wind | Annual units |
|---|---|---|---|---|---|
| 2 BHK home | 3 kW | 3 kW string | — | — | ~4,350 kWh |
| Independent villa | 8 kW | 8 kW string / hybrid | Optional 10 kWh | Optional 2 kW VAWT | ~11,600 kWh |
| Apartment common area | 20–120 kW | Multiple string | Optional for lifts / pumps | — | ~29,000–174,000 kWh |
| School / college campus | 50–250 kW | String, multi-MPPT | — | Optional campus mast | ~72,500–362,500 kWh |
| Hospital | 60–200 kW | Hybrid | 50–200 kWh LFP | Optional | ~87,000–290,000 kWh |
| Factory shed | 100 kW–1 MW | String / central | Peak-shaving BESS | Mast-mounted where viable | ~145,000–1,450,000 kWh |
| Farm / agri-processing | 10–50 kW | Hybrid | 20–60 kWh LFP | 5–20 kW HAWT | Site-specific |
| Captive ground-mount | 500 kW–5 MW | Central / string | Optional | Optional | ~725,000–7,250,000 kWh |
PV yields calculated at 1,450 kWh per kW per year. Wind yield is never estimated without a site-specific resource study — see Wind Energy.
Warranty & quality
Warranties come from three different places, and knowing which is which matters when something goes wrong. We administer all three on your behalf.
Product and performance warranties on modules, inverter, battery and turbine — issued by the maker. We register every serial number and keep the paperwork so a claim years later is not your archaeology project.
Our own cover on installation, structure and wiring. If a leak, a loose connection or a mounting failure traces back to how we built it, we come and fix it at our cost.
The generation model in your proposal is the benchmark. We review actual against modelled at three and twelve months, and where a shortfall is within our scope to correct, we correct it.

Every SunX proposal lists make, model, quantity and warranty term for every component before you pay anything — and nothing gets substituted on site without your written approval.
