Who we work with

Industries we serve

Every site uses power differently. We design around your working hours, machines and roof.

  • Textile & spinning mills

    Mills that run long shifts with steady machine loads can use a large share of daytime solar directly, and often have wide shed roofs to build on.

  • Foundries

    Heavy, power-hungry processes make energy a major cost. We look at your load pattern to see how much rooftop or off-site solar can cover.

  • Pump & motor manufacturers

    Machining, winding and testing lines that run in daytime shifts are a natural fit for solar generation.

  • Engineering units

    CNC shops, fabrication and job-work units in Coimbatore's industrial areas can lower their day-shift power cost.

  • Hospitals

    Round-the-clock loads such as air conditioning, lighting and equipment make daytime solar useful. Backup systems stay as they are.

  • Schools & colleges

    Campuses use most of their power during the day, when solar generates. Large building roofs are often available.

  • Hotels

    Air conditioning, kitchens, laundry and water heating add up. Solar can take care of part of that daytime demand.

Your options

Rooftop, open access or group captive?

There are three common ways for a business to use solar power. Which one fits depends on your load, your site and the rules in force at the time. We check this during the energy audit.

The PM Surya Ghar subsidy is for homes only

The PM Surya Ghar rooftop solar subsidy is a residential scheme. It does not apply to commercial or industrial customers. Your business case rests on the power cost you save, not on a subsidy.

Rooftop solar (net / gross metering)

What it is
Solar panels on your own factory or building roof, connected to your TNPDCL service. Under net metering, units you send to the grid are set off against units you draw. Under gross metering, the plant's output is fed to the grid and paid for at the applicable rate. Which arrangement is open to your connection depends on current TNPDCL rules.
Who it suits
Businesses with usable roof space and a good share of daytime consumption. Often the simplest starting point, especially for smaller and medium loads.
What we handle for you
Energy audit, roof and structure check, system design, brand selection, TNPDCL metering application and paperwork, installation, commissioning, and O&M afterwards.

Open access

What it is
Solar power produced at a plant located elsewhere, often on land away from your factory, and delivered to your premises through the grid under an open access approval. Grid-related charges apply as per the rules in force.
Who it suits
Larger loads with steady consumption, or sites where the roof is too small to meet a meaningful share of demand.
What we handle for you
Feasibility study, plant design and EPC installation, support with the open access application and documentation, commissioning, and O&M of the plant.

Group captive

What it is
An off-site solar plant in which several consumers hold an ownership stake and use its power as captive users, following the captive generation rules. Each member's share of power and equity must meet those rules.
Who it suits
Larger consumers, or groups of businesses, who want long-term control over their power cost and can invest in a shared plant.
What we handle for you
Technical feasibility, plant design and EPC installation, the technical documents needed for approvals, commissioning, and O&M of the plant.

We do not push one route. After the energy audit we explain the options that genuinely suit your site, with the reasons.

Payback

What decides your payback period

There is no single payback figure that fits every business. These are the factors that decide how quickly a solar plant pays for itself at your site.

  • Your electricity tariff

    The higher the rate you pay per unit to TNPDCL, the more each solar unit saves you. Your tariff category and any demand-related charges both matter.

  • Your load profile

    How much power you draw, and how steady it is through the day and week. A steady load uses solar output well; large swings need careful sizing.

  • Daytime consumption

    Solar generates during daylight hours. The more of your consumption that happens in the day shift, the more solar power you use directly.

  • Roof area and condition

    Usable, shade-free roof area limits how large a rooftop plant can be. Roof type and structural strength also affect design and cost.

Accelerated depreciation

A solar plant bought by a business may qualify for accelerated depreciation under the Income Tax Act, which can improve the after-tax return. Eligibility and the rate that applies depend on the current rules and your company's situation. Please consult your Chartered Accountant (CA) before you rely on it.

The energy audit looks at your actual bills, load and roof, so the proposal you receive is based on your site and not on a generic example.

Multi-brand advantage

The right panels and inverters for your project

We are not tied to a single brand. We recommend a panel and inverter combination matched to your project's needs.

  • Your roof: space, orientation, shading and structure
  • Your budget and how you plan to fund the project
  • Your load: how much power you use, and when

Brands we install

We supply & install solar panels from these manufacturers.

  • Adani
  • Waaree
  • Tata Power Solar
  • Vikram

Brand names and logos belong to their respective owners. Listing a brand here does not mean the manufacturer endorses us.

After commissioning

O&M, AMC and remote monitoring

A solar plant keeps saving money only if it keeps performing. We stay with you after the plant is running.

  • Operations & maintenance

    Periodic panel cleaning, inspection of wiring, inverters and structures, and prompt attention when something needs repair.

  • Annual maintenance contract

    An AMC sets out the scope and schedule of maintenance for the year, so upkeep is planned and budgeted rather than left to chance.

  • Remote performance monitoring

    Your plant's generation can be tracked remotely, so a drop in output is noticed early and checked before it costs you much.

How it works

From energy audit to a running plant

  1. Step 1

    Energy audit

    We visit your site, study your electricity bills, load pattern and roof, and understand how you use power.

  2. Step 2

    Proposal & ROI

    You get a proposal with the recommended route, system design, equipment and a payback explanation based on your data.

  3. Step 3

    Approvals

    We prepare the documents and support the applications needed with TNPDCL and other authorities for your chosen route.

  4. Step 4

    EPC install

    Engineering, procurement and construction: structures, panels, inverters, cabling and safety systems installed by our team.

  5. Step 5

    Commissioning & O&M

    We test and commission the plant, then support you with maintenance, AMC and monitoring.

Questions from business owners

Can my factory get the PM Surya Ghar subsidy?

No. PM Surya Ghar is a residential rooftop scheme. It does not apply to commercial or industrial customers, so a factory, shop, hospital, school or hotel should not plan its project around it. The return on a business solar plant comes from lower power bills.

What is the difference between open access and group captive?

In both cases the solar plant is usually located away from your premises and the power reaches you through the grid. With open access, you buy solar power from a plant under an open access arrangement. With group captive, you and other consumers hold an ownership stake in the plant and use its power as captive users, following the captive rules. Which suits you depends on your load, your investment plans and the rules in force, and we explain this after the energy audit.

Should we start with rooftop solar?

For many businesses with usable roof space and daytime consumption, rooftop solar is the simplest place to start. If your roof is too small for your demand, open access or group captive may be worth considering alongside it.

Is there a tax benefit for installing solar?

A solar plant bought by a business may qualify for accelerated depreciation under the Income Tax Act. Eligibility and the rate depend on the current rules and your company's situation, so please consult your Chartered Accountant (CA).

Do you maintain the plant after installation?

Yes. We offer operations and maintenance, annual maintenance contracts and remote performance monitoring after commissioning, so problems are noticed and fixed early.

How long does a project take?

It depends on the size of the plant, the route you choose and the time taken for approvals. We give you a project schedule with the proposal, and keep you informed at each stage.

Can solar go on our factory's metal sheet roof?

Often, yes. Metal sheet and concrete roofs can both carry solar, but we check the roof's condition and structural strength first and design the mounting to suit it.

Will solar run our machines during a power cut?

A grid-connected solar plant switches off when grid supply fails, for the safety of line workers. It reduces your power bill; it is not a backup supply. Your existing backup arrangements continue to work as before.
