Powering a sustainable future through smarter energy solutions.

The equipment we build with, and why

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

Everything that goes into a SunX system

Filter by category to see what we specify, and the questions we ask before choosing between makes.

Mono PERC modules

The current mainstream: high efficiency, well-understood degradation, and the deepest service and replacement network in India. Our default for cost-sensitive residential work.

  • Typically 540–590 Wp, half-cut cells
  • 12-year product / 25-year performance warranty
  • IEC 61215 & 61730 certified, ALMM-listed makes

N-type TOPCon modules

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.

  • Typically 570–630 Wp, bifacial options
  • Lower temperature coefficient than PERC
  • Up to 30-year performance warranty on some makes

Bifacial modules with elevated mounting

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.

  • Rear-side gain typically 5–15% depending on albedo
  • Glass-glass construction, better moisture resistance
  • Needs elevated or ground mounting to pay off

String inverters

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.

  • 1 kW to 250 kW, single and three phase
  • Multiple MPPT trackers for split or shaded roofs
  • Wi-Fi / LAN monitoring, IP65 outdoor rating

Hybrid inverters

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.

  • 3 kW to 50 kW, parallel-stackable
  • Fast changeover on critical circuits
  • Time-of-use, peak-shaving and export-limit control

Micro inverters & optimisers

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.

  • Module-level monitoring and fault isolation
  • No high-voltage DC on the roof
  • Best for complex villa and heritage roofs

LFP battery banks

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.

  • 5 kWh to 500 kWh, rack or wall-mount
  • Integrated BMS with cell balancing
  • Typically 6,000+ cycles at 80% depth of discharge

Commercial BESS

Containerised or cabinet storage for peak shaving, demand-charge management and genset displacement, with the control logic tuned to your tariff structure.

  • Demand-charge and time-of-day optimisation
  • Fire detection and thermal management
  • Retrofits onto existing grid-tied plants

Vertical-axis wind turbines

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.

  • Typically 1 kW to 10 kW per unit
  • Low cut-in speed, low noise, damped mounts
  • Electromagnetic and mechanical braking

Horizontal-axis small turbines

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.

  • Typically 5 kW to 50 kW per machine
  • Mast height selected from the wind profile
  • Foundation design and structural certification

Mounting structures

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.

  • Hot-dip galvanised MS or Al 6063-T6
  • Designed to IS 875 wind loading for the site
  • Non-penetrative and sealed-penetration roof options

Elevated & car-park structures

Purpose-built canopies that generate above while the yard, parking or walkway below stays fully usable — with proper drainage and clearance designed in.

  • Clear heights from 2.5 m to vehicle-access spans
  • Gutter and downpipe integration
  • Optional EV charging points below

Protection & earthing

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.

  • DC SPDs, fuses, isolators, AC MCCB / RCCB
  • Chemical earthing pits with earth-resistance testing
  • Lightning arrestor with dedicated down-conductor

Cabling & combiner boxes

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.

  • Loss budget calculated and stated in the design
  • IP65 combiner boxes with string monitoring
  • MC4 connectors, crimped and tested, not twisted

Monitoring & metering

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.

  • Mobile and web dashboards with historical data
  • Alert escalation to a person, not just a screen
  • Monthly performance-ratio report under AMC
On brands: we do not publish a fixed brand list because the right choice moves with pricing, ALMM listings, lead times and local service. The approved-makes list for your project is stated in your proposal, and we are happy to work to a make you have already standardised on. Ask for the current approved-makes list.

Warranty & quality

What is guaranteed, and by whom

Warranties come from three different places, and knowing which is which matters when something goes wrong. We administer all three on your behalf.

Manufacturer warranty

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.

Workmanship warranty

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.

Performance commitment

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.
