System Design and Basic Engineering

Basic engineering is carried out based on the selected plant components. The key electrical systems, civil structural and infrastructure systems are conceptualized 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 include sizing of connectors, connection boxes, string combiner boxes, DC distribution boards, DC cable run lengths and sizes.
• AC side Electrical system designs 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.
• Surrounding obstacles to assess shading impact.
• 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.

In the process of our detailed engineering services, our team performs reviews of the selected equipment and drawings received from various suppliers and contractors, and coordinates the release of various construction drawings for site execution.
