Engineered to standards.
Drawing sets prepared to align with IS/IEC norms and DISCOM requirements — so approvals, audits and handovers go smoothly.
02How A Plant Comes Together
From the first module to the grid connection
Scroll and the plant builds itself — piles driven, steel raised, modules fitted, power flowing, batteries charging, export to the grid. Scroll back and it comes apart again.
Piling
Foundations first
Stage 01
Foundations go in first
Nothing stands without this. Pile type and depth come from the soil report, checked for pull-out under wind and for the loads the finished array will put into the ground.
- Pile layout set out from the array drawing
- Depth and section sized to the soil investigation
- Pull-out and bearing checks against wind loading
- Pile caps levelled ready for steel
Stage 02
Steel rises on the piles
Posts, rails and purlins carry every module for twenty-five years. Tilt and row pitch are fixed here, and they decide how much the plant generates for the rest of its life.
- Table design with front and rear post heights
- Tilt angle and row pitch set for the latitude
- Purlin spacing matched to the module frame
- Wind-load and deflection checks on the structure
Stage 03
Panels go on
Modules land on the tables and get clamped down. The string layout decides how they are grouped electrically, which is why the layout and the electrical design are drawn together.
- Module placement and clamping positions
- String grouping and series counts
- Walkway and maintenance access kept clear
- Shading rechecked against the as-built layout
Stage 04
Current starts to move
With the array complete, power has somewhere to go. Strings gather into combiners, the inverter turns DC into AC, and the transformer lifts the voltage ready to travel.
- Combiner boxes and DC cable routing
- Inverter sizing and DC to AC ratio
- Transformer rating, cooling and protection
- Earthing and lightning protection throughout
Stage 05
The batteries take charge
Surplus generation charges the BESS instead of being wasted. Capacity is matched to the load profile, and the containers are laid out with the clearances safety requires.
- Battery sizing in MW and MWh for the load profile
- Container layout, access and cable routing
- PCS integration between batteries, plant and grid
- Auxiliary power, HVAC and fire-safety separation
Stage 06
Power leaves for the grid
The final link. Through the switchyard, up the gantries and away along the conductors — metered, protected and documented for the utility.
- Switchyard layout and bay arrangement
- Bus-bar design with safe electrical clearances
- Earthing mat sized for step and touch voltages
- Metering and the utility interface
03Also With Us
Support at every step
Site Survey & Feasibility
Know before you commitBefore anyone talks about price, we find out what your site can genuinely support — and tell you plainly if the answer is less than you hoped.
- Shading study across the year, allowing for parapets, water tanks, stair rooms and neighbouring buildings
- Roof structure and load assessment — what the building can safely carry, and where reinforcement is needed
- Sanctioned load, metering point and cable route checked on site, not assumed from drawings
- A written report with realistic generation, savings and payback figures you can take to your board
Solar Consulting & Audits
Independent engineering eyesFor plants already running, or designs drawn up by someone else. We look at the engineering on its merits and report what we find, whether or not it suits us.
- Performance audit — tracing why a plant generates below its estimate, string by string
- Third-party review of another vendor’s design before you sign or release payment
- Health check on mounting structures, cabling and earthing after a few seasons in service
- Capacity expansion planning — what more the existing roof, structure and connection can take

05Common Questions
Working with us — what people ask
If your question is not here, send it over and we will answer it plainly.
Are your drawings ready for DISCOM approval?
Yes. Drawing sets are prepared to align with IS/IEC norms and DISCOM requirements, so they hold up in technical review without repeated revisions. You receive a complete, review-ready package to submit.
What is actually in a design package?
PV sizing and yield simulation, array layouts with shadow analysis, structural and mounting design, electrical single-line diagrams and cable schedules, a bill of quantities for procurement, and approval and as-built drawing sets. Enough for your installers to build from without guessing, and enough for a lender or auditor to review.
Do you work outside Delhi NCR?
Yes. We are based in New Delhi and survey sites across Delhi, Gurugram, Noida, Faridabad and Ghaziabad, but we take on design and engineering work across India — completed projects include sites in Haryana and Rajasthan.
Can you work on a plant somebody else installed?
Yes. We audit existing plants to find out why generation is below estimate, review another vendor’s design before you sign or release payment, and plan capacity expansions on roofs that already carry an array.
Do you also install the system?
Design and engineering is all we do — we are a consultancy, not an EPC. You build with your own teams or your chosen contractor, and we stay available through construction to answer questions on the drawings.
Let's design your next project.
Send us your site details or drawings — we'll come back with a clear design proposal, honest timelines and a set your installers can build from.
