We don't just install panels. We engineer generation assets.
For more than two and a half decades, ATPSPL has commissioned and maintained thermal generation across India — over 1000 MW and counting. That same discipline in design, procurement, commissioning and O&M now drives every solar project we build. When your generation has to perform for 25 years, the engineering behind it matters.
- End-to-end EPC: feasibility, design, supply, erection, testing & commissioning
- Bankable engineering with documented standards and inspection protocols
- In-house Operation & Maintenance — the discipline we already run on power plants
- Single point of accountability, from concept to commissioning
Solar solutions for every scale of demand
Whether you're trimming a factory's energy bill or building a merchant-scale asset, we size and engineer the right configuration.
Rooftop Solar
Maximise idle roof area on factories, sheds and offices. Engineered mounting, clean cable management, and structural sign-off you can trust.
Ground-Mount
Utility-scale arrays on open land, designed for yield — optimal tilt, row spacing and terrain-aware layouts up to 100 MW.
Net-Metering
Offset your own consumption and export surplus to the grid. We handle the sizing, the paperwork and the DISCOM coordination.
Open Access
Wheel power from a remote plant to your facility. We model the commercials and engineer for compliance, banking and long-term savings.
From 300 kW to 100 MW — sized to your load
☉ By Mounting
- Rooftop — RCC, metal sheet & standing-seam structures
- Ground-mount — fixed-tilt & seasonal-tilt arrays
- Carport & shed-integrated configurations on request
- Structural & wind-load engineering for site conditions
⇄ By Commercial Model
- Net-metering — offset consumption, export surplus
- Open Access — third-party & group captive structures
- Captive generation for industrial & commercial loads
- CAPEX & advisory on RESCO/OPEX routes
Go solar with — or without — investment
Some clients want to own the asset and capture the full savings. Others want the savings with zero capital outlay. We structure the deal around your balance sheet, not ours.
You invest, you own
With investment
You fund the plant upfront and own a generating asset that pays back in a few years and then runs near-free for decades. Best when you want maximum lifetime savings and full control of the asset.
- You own the system and the full power generated
- Highest long-term savings and lowest per-unit cost
- Accelerated depreciation & tax benefits available
- Asset on your books — strong ROI after payback
- End-to-end EPC plus optional O&M from ATPSPL
We invest, you save
Without investment
We (or our partners) finance, build and maintain the plant on your site. You pay only for the units you consume — typically well below your grid tariff — through a power purchase agreement. Best when you want savings from day one with no capital outlay.
- Zero upfront investment from your side
- Pay per unit (PPA) — usually cheaper than the grid
- We own, operate and maintain the plant
- Savings from the very first bill, no capital risk
- Option to buy out the plant at a later stage
Not sure which fits? One call settles it. Share your load and tariff, and we'll show you the numbers for both routes side by side — so you choose with or without investment, as your requirement demands.
Concept to commissioning — one accountable team
Assessment
We study your load profile, tariff, roof or land, and savings potential — on a single call.
Engineering
Bankable design: sizing, yield modelling, BoM, single-line diagrams and structural checks.
Execution
Procurement, erection, testing and commissioning to documented standards.
O&M
Ongoing performance monitoring and maintenance — the same rigour we bring to power plants.
Your roof is earning nothing today. Let's change that.
One conversation tells you the size, the savings and the payback for your site. No obligation — just straight engineering answers.

Engineers, not call centres
When you call, you reach the people who will actually build your plant.
Built for payback
Every design is optimised for yield, savings and long-term return — not just installation.
Questions buyers ask before they call
What project sizes do you take on?
Do you handle the approvals and DISCOM paperwork?
Can you maintain the plant after commissioning?
Do I have to invest upfront, or can I go solar without capital?
