detailed engineering

On completion of the feasibility
analysis of a project,

wherein the basic design and project implementation strategies are established with the necessary approvals, permits, and agreements in place, the project then moves into its next phase, which is Detailed Engineering.

Multi-disciplinary
Engineering

We enable project developers to leverage the benefits of a split contract structure for developing solar power projects. From DC side electrical engineering to infrastructure, structures, AC side engineering, and substation engineering, we provide comprehensive engineering services.

We have provided detailed engineering for over 17GW of solar projects in various countries like India, Bangladesh, Sri Lanka, Jordan, Vietnam, the USA, Egypt, and other African countries.

Our
Proficiency –
Your Benefits

Value engineering forms the core of all our detailed engineering offerings.

Accurate project design ensures the project is optimised for the least CAPEX.

Unparalleled expertise in PV array layout arrangement.

Setting-up trends in Power Collection System

Designing as per the modern grid requirements of Automation, Smart Grid, Micro-Grid, Cybersecurity and others.

Optimising the design for the system to be capable of curtailing to further needs and being redundant at all times.

Our Services

detailed engineering

Basic engineering is carried out based on the selected plant components.
The key electrical systems, civil structural, and infrastructure systems are conceptualised
following the tender designs and specifications:

Overall layout, including string and module grouping, module orientation and inclination, row spacing, cable plans, nominal power ratio sizing, inverter and substation design.

DC-side electrical system design right from the PV module to the inverter inputs. This essentially includes the sizing of connectors, connection boxes, string combiner boxes, DC distribution boards, DC cable run lengths and sizes.

AC-side electrical systems are designed from the inverter output to the grid interconnection and metering point. This will essentially include the LV/MV and MV/HV transformers, grid connection schematics, and metering.

Assessing the impact of surrounding obstacles on shading

Review of geotechnical investigations

Review of topographic surveys

Review of hydrology studies

Assessment of support structure foundations, buildings, roads, and infrastructure required for implementation and operation.

Site security and access

Control and monitoring systems.

Detailed Engineering

Our team prepares the designs, project engineering and execution drawings in conjunction to the technical specifications, design criteria and procedures, best of engineering codes and standard engineering practices for a utility scale solar PV plant.
