A worked example, not a specific client roof.

  1. 02

    Site

    We measure the roof itself — usable span, shading, structure, and where your meter already sits.

    Structure

    Galvanised rails on the purlin lines, sealed at every penetration. Sheet roofs mount direct; RCC needs an elevated structure, which is why the rates differ.

    Modules laid flush, with walkways left for the people who will clean and service the plant for twenty-five years.

    Strings and inverter

    Balanced strings landed on the inverter. Earthing to IS 3043 and surge protection are in the scope, not on a revised quote.

    Net meter

    The DISCOM fits a bi-directional meter. Whatever the roof makes beyond your load is exported and banked against a later bill — we file the application and follow it through.

    Handover

    Tests, as-built drawings, warranties and the maintenance schedule handed over as one file — then the same team keeps the plant performing.

Your roof will not be this roof. Put your own bill in and the same arithmetic runs on your location, your DISCOM tariff and your roof type.

What one team signs for

Six scopes, all held by the same contract.

01
Solar EPC Solutions

Complete, turnkey solar EPC tailored to your site — engineered, procured and built by one accountable team.

02
Annual Maintenance Contracts

Keep your plant clean, monitored and performing — with rapid response when something goes wrong.

03
Consulting Services

Independent, engineering-led advice on whether, what and how to go solar.

04
Project Management

06
Energy Storage Solutions

Size, integrate and commission battery storage so your solar energy is there whenever you need it.

One contract. One team. One signature at handover.

Most solar disappointments are not engineering failures. They are hand-off failures — the surveyor blames the designer, the designer blames the installer, the installer blames the DISCOM, and the plant sits at seventy per cent of what it was sold as.

The people who walk your roof are the people who engineer it, order the parts, erect the structure, file the net-metering application and come back for the maintenance visits. One number to call, and nobody to point at.
