Ltd.) --- Case Study · Industrial · Rooftop I&C # Balaji Action Buildwell, Sitarganj: Solar I&C, BOS and Civil Works Installation & commissioning, balance-of-system works, civil works and approvals on Balaji Action Buildwell's solar project at Sitarganj, Uttarakhand, for Tata Power Solar. The Project ## About the Balaji Action, Uttarakhand project The orders describe the project in more than one way, and we show each scope as it was ordered rather than adding the figures together: rooftop BOS services for a project of 4000.32 kWp, installation & commissioning of a sheet-roof plant described as 3 MWp, and civil works with pile foundations for a ground-mount plant also described as 3 MWp. Tata Power Solar's 2022 orders also covered a labour colony for the site crew and the CEIG approvals for the project. Further orders in 2023 covered additional I&C work, an ITB canopy, additional cable trays, fire extinguishers and sand buckets, and cable lugs: the details that take a large plant from installed to inspected and handed over. ### Our scope of work - Installation & commissioning of the 3 MWp sheet-roof plant - Rooftop BOS services for the 4000.32 kWp project - Civil work and pile foundations for the ground-mount portion - CEIG approvals - ITB canopy, cable trays and fire safety equipment - Labour colony for the site crew ### Photos ## Project facts Capacity: **4000.32 kWp project (as described in the BOS order)** Plant type: **Sheet-roof I&C (ordered as 3 MWp) and ground-mount civil works** Location: **Sitarganj, Uttarakhand** Client: **Balaji Action Buildwell Pvt.

On Site ## Challenges and How We Handled Them ### Roof and ground on one site A large sheet-roof plant and ground-mount civil works meant two very different jobs, height work and piling, on one industrial campus. ### A camp for the crew With a large crew on site for months, a proper labour colony was part of the scope: decent living conditions are part of working safely. ### Approvals as part of the job CEIG approvals for the project were in our scope, so inspection was planned into the schedule rather than added at the end. Installation & Commissioning ## What Our I&C Scope Covered The standard rooftop installation & commissioning scope we deliver to EPC majors' specifications, after the mandatory quality and safety training and contractor safety sign-off. ### Civil works - Earth-pit chambers and covers (RCC/PCC) - Foundations for inverters, ACDB, ITB and accessories - Cable trenches at ground level ### Mechanical - Lifting and handling of all material to the roof - Module mounting structure installation on the sheet roof - Module installation and interconnection - Canopies for wall-mounted inverters and junction boxes ### DC side - String wiring from modules to inverters, tagged and identified - DC cables in conduit or tray - MC4 connectors crimped male and female - Array junction boxes ### AC side and protection - Inverters and inverter terminal boxes - AC distribution board (ACDB) - LT AC cables in trays to the approved layout - Reverse power relays installed and commissioned ### Earthing and lightning - Earth electrodes and pits - Earthing strips for structures, inverters and ACDB, including welding - Lightning arrestors ### Roof safety and access - Skylight safety mesh - Walkways and hand rails - Safety lifelines for workers - Scaffolding for installation ### Monitoring, cleaning and handover - Data monitoring system (SCADA / power manager) - Module cleaning system with pump and motor - Safety posters, storage under covers and care until handover - Testing, commissioning and handover [The full commissioning checklist](https://arraysingenieria.com/solar-plant-commissioning-checklist/)[Our I&C service](https://arraysingenieria.com/solar-installation-commissioning/) Related ## Services Used on This Project [Installation & Commissioning](https://arraysingenieria.com/solar-installation-commissioning/)[Rooftop Solar](https://arraysingenieria.com/service-rooftop/)[Civil Works & Fencing](https://arraysingenieria.com/service-civil/)[All Projects →](https://arraysingenieria.com/projects/) More Case Studies ## Other Projects by Arrays Ingenieria [Industrial · Rooftop: **Super Smelters: 1980.3 kWp Rooftop Solar Plant**1980.3 kWp (about 2 MW) · Jamuria (Asansol), West BengalRead the case study](https://arraysingenieria.com/project-super-smelters-1980kwp-rooftop-solar/)[Industrial · Rooftop I&C: **SRMB Steel, Durgapur: Rooftop Solar I&C in Three Phases**1895.4 kWp, 1060 kWp and 1.69 MWp · Durgapur, West BengalRead the case study](https://arraysingenieria.com/project-srmb-steel-durgapur-rooftop-solar/)[Industrial · Rooftop I&C: **Apar Industries, Jharsuguda: 1.2 MWp Rooftop Solar I&C**1.2 MWp (1203 kWp) · Jharsuguda, OdishaRead the case study](https://arraysingenieria.com/project-apar-industries-jharsuguda-1-2mwp-rooftop-solar/)
