How It Works

# How a Solar Project Works with Us

How solar makes power, the three ways to work with us, and every step from your first call to a plant generating power.

How Solar Works

## From Sunlight to Savings

What happens inside a grid-connected solar plant.

Sunlight → solar modules make DC power → the inverter converts it to AC → your site uses it → surplus is exported to the grid through a net meter.

Choose Your Path

## Three Ways to Work With Us

[1CAPEX / full EPC: **Own your plant**For factories, businesses and tea estates

- We design, supply, build and commission the complete plant
- You pay once and own everything
- Civil works, approvals and handover included

- You own the design and the equipment
- Our veteran-led crews install and commission
- Work to your specifications and approved makes

- Pile foundations for module structures
- RCC, pre-cast boundary walls, chain-link fencing
- Proven on SECI 300 MW and Tata Motors 5.5 MW

Step by Step

## Your Project, From Enquiry to Energised

The journey for a CAPEX or full-EPC plant. For I&C and civil work we join at the steps you need.

- 1

### Enquiry

You contact us with your site, your power use and what you want built.

**You get:** A call with our team, the same week

- 2

### Site survey & load study

We visit your roof or land, study your load profile, your grid connection and any diesel generators.

**You get:** Survey findings and a recommended plant size

- 3

### Design & proposal

System design, bill of quantities and a scope-of-work matrix showing exactly what we supply and what you supply.

**You get:** A clear quotation and scope matrix

- 4

### Order & mobilisation

Your purchase or work order, then a site safety plan and a day-by-day programme.

**You get:** Programme, safety plan, named site lead

- 5

### Procurement

Tier-1 modules, inverters and balance-of-system equipment, or the makes you have approved.

**You get:** Equipment delivered to site

- 6

### Civil & structures

Pile foundations or roof works, module mounting structures, fencing and boundary walls where needed.

**You get:** Foundations and structures, checked for level and alignment

- 7

### Installation

Modules, DC and AC cabling, inverters and boards, earthing, lightning protection, module cleaning system and DG synchronisation where needed.

**You get:** A complete, inspected plant

- 8

### Approvals & commissioning

Net-metering and DISCOM approvals and inspections, testing, and grid synchronisation.

**You get:** A plant generating power

- 9

### Handover & support

As-built documents, test reports and equipment warranty papers handed over, your team shown how to run the plant; O&M support if you want it.

**You get:** Your plant, fully documented

Who Owns What

## Under CAPEX, It Is All Yours

### You own

- The complete plant and all its equipment
- Every unit of power it generates
- All the savings, for the life of the plant
- The tax benefit, for businesses
- The manufacturers' warranties

### Arrays Ingenieria

- Is paid once to design, supply, build and commission
- Owns nothing in your plant
- Offers O&M support only if you ask for it
