Powering a sustainable future through smarter energy solutions.

A renewable energy company built by people who will still answer the phone in year ten

SunX Solar and Renewable Solutions is a Hyderabad-based solar and wind EPC. We engineer, install and maintain generation assets on roofs, sheds and land across Telangana and Andhra Pradesh.

About the company

Powering a sustainable future through smarter energy solutions

That line is on our business card because it is the actual brief we set ourselves. Not more panels — smarter systems.

India’s rooftop market has no shortage of installers. What it lacks is engineering discipline: systems sized to a real load curve, structures designed for real wind loads, cable runs costed for real losses, and a maintenance plan that exists before the invoice is raised. Too many plants in this city are quietly generating twenty percent below what their owner was promised, and nobody is measuring.

SunX was founded to close that gap. We keep design, procurement, installation and O&M in-house so that the person who modelled your generation is accountable for delivering it. We publish our assumptions. We hand over drawings, test reports and warranty documents as a matter of course. And we say no to projects where the numbers do not work — a shaded roof, an unsuitable structure, a load profile better served by efficiency than by generation.

Alongside solar, we have deliberately built capability in the new generation of compact wind turbines. They are still unusual on Indian rooftops, and that is precisely the point: for many sites in the Deccan wind belt, a small turbine paired with PV and storage produces a flatter, more useful generation curve than either technology alone.

Based in Serilingampally

Serving Hyderabad, Ranga Reddy, Medchal, Sangareddy and project sites across Telangana and Andhra Pradesh.

Solar, wind and storage

One team, three technologies — so the recommendation is driven by your site, not by what we happen to sell.

What drives us

Purpose, ambition and the rules we hold ourselves to

Our mission

To make self-generated clean power the default choice for buildings in South India — by delivering renewable energy systems that are engineered properly, priced honestly and maintained for their full life.

Our vision

A Hyderabad where every viable roof, shed and idle acre is generating, and where solar-plus-wind hybrids with storage let ordinary buildings run around the clock on their own power.

Our promise

What we model is what we install. What we install is what we maintain. If a plant under-performs its model and the cause is ours, correcting it is ours — not a change order.

Engineering excellence

Design decisions are defended with numbers — irradiation data, shadow studies, loss budgets and structural calculations.

Integrated EPC delivery

One accountable team from survey to commissioning. No subcontract chain to hide behind when something needs fixing.

Quality and safety

Certified components, torque-checked fastenings, proper earthing and lightning protection, and fall-safety discipline on every roof.

Customer-centricity

Plain-language proposals, no pressure selling, and an honest “this site is not suitable” when that is the right answer.

Sectors we serve

Different buildings, different load curves, different answers

A school consumes when the sun is up. A hospital cannot be interrupted. A cold store runs all night. The right system follows the load, and these are the profiles we design for.

Homes & villas

2–15 kW grid-tied rooftops with subsidy support, sized to wipe out the highest tariff slabs first.

Gated communities

Common-area and lift/pump load offset, with society-rate subsidy and per-block metering clarity.

Schools & colleges

Daytime-heavy consumption makes campuses the best fit in the market — often the fastest payback we model.

Hospitals & labs

Hybrid systems with battery back-up that carry critical circuits through an outage without waiting for a generator.

Manufacturing & MSME

Shed-roof and elevated-structure plants under CAPEX or OPEX, with accelerated depreciation modelled in.

Agriculture & agri-processing

Solar pumping, cold-room support and wind-solar hybrids for sites where the grid is weak or the tail is long.

Leadership

Who you will actually be dealing with

Small company, senior contact. The person who surveys your site is the person who signs off its design.

SL

Sree Lavanya Thammu

Co-Founder & Project Manager

Owns project delivery end to end — site assessment, design sign-off, DISCOM and subsidy paperwork, installation scheduling and handover.

Engineering desk

Load studies, shadow analysis, string sizing, structural and loss calculations, and the drawing set that goes out with every proposal.

Installation crew

Our own trained technicians for structure, module, inverter and cabling work — not a rotating pool of subcontracted labour.

Service & O&M cell

Cleaning schedules, monitoring alerts, breakdown response and the monthly performance report on every plant under contract.

Where we are headed

Our build-out plan, stated plainly

SunX is early — and we would rather be judged on a plan you can hold us to than on numbers nobody can verify.

Investors and channel partners: a detailed capability deck, equipment tie-ups and a project pipeline summary are available on request. Get in touch and we will send it across.
  • Now Residential and institutional rooftops across Hyderabad

    Grid-tied systems from 2 kW to 100 kW, with full subsidy and net-metering handling. Site surveys within two working days across the city.

  • Next Compact wind and hybrid storage as a standard offering

    Structural and wind-resource assessment capability in-house, so a rooftop turbine or wind-solar hybrid can be quoted as confidently as a PV array.

  • Then Commercial and industrial scale

    Shed-roof and ground-mount plants in the 250 kW to multi-MW band, including OPEX and group-captive structures for MSME clusters.

  • Ambition An O&M portfolio worth trusting

    Every plant we build stays on our monitoring platform for its life, plus revival contracts for under-performing third-party plants across the twin cities.

Talk to us

Bring us a roof, a bill and a question

We will tell you what your site can realistically generate, what it will cost after subsidy, and whether solar, wind or a hybrid is the right answer — in writing.
