Solar Pv Design Engineer

Solar Design Engineer and HV Substation Design Engineer (Rooftop / Ground-Mounted Solar Projects)

Primary Role:

Key Responsibilities:

• System Design

  : Prepare PV system designs (rooftop/ground-mounted) including array layouts, single-line diagrams (SLD), and electrical drawings.

• Software Simulation

  : Use tools like PVsyst, Helioscope, AutoCAD, or SketchUp for energy yield assessment, shading analysis, and design validation.

• Electrical Sizing

  : Calculate cable sizing, inverter sizing, protection devices, earthing, and lightning protection.

• Compliance

  : Ensure designs follow IEC/IS codes, CEA regulations, DISCOM/CEIG requirements, and net-metering policies.

• BOQ Preparation

  : Prepare bills of quantities and technical specifications for procurement.

• Site Assessment

  : Conduct site visits, evaluate feasibility, and optimize system design based on available area, tilt, and shading.

• Coordination

  : Work with EPC teams, contractors, and clients for design approvals and execution.

• Performance Analysis

  : Monitor system performance post-installation and suggest improvements.

• Substation Layout Design

  : Develop physical layouts, equipment arrangement (transformers, breakers, isolators, busbars, control rooms).

• Single Line Diagram (SLD) & Schematics

  : Prepare electrical schematics, protection schemes, interlocking, and control wiring diagrams.

• Equipment Sizing & Specification

  : Select and size transformers, CT/PTs, circuit breakers, surge arresters, isolators, earthing, and cabling.

• Protection & Control Systems

  : Design protection relays, SCADA systems, metering, and automation systems.

• Grounding & Earthing

  : Design earthing systems as per IEEE/IS standards, step and touch potential calculations.

• Short-Circuit & Load Flow Studies

  : Perform studies using ETAP, DIgSILENT, or PSCAD to validate protection and equipment ratings.

• Compliance & Standards

  : Ensure designs adhere to IEC, IEEE, IS, CEA, and utility/grid codes.

• Civil/Structural Coordination

  : Coordinate with civil team for foundations, cable trenches, and structural drawings.

• Documentation & Approvals

  : Prepare detailed engineering documents, technical specifications, and liaise with utility/consultant for approvals.

• Testing & Commissioning Support

  : Assist site teams during erection, testing, and commissioning.

Skills Required:

• Strong knowledge of electrical engineering fundamentals.
• Proficiency in PV design software (PVsyst, Helioscope, AutoCAD, ETAP optional).
• Knowledge of solar panel, inverter, and BOS (Balance of System) components.
• Understanding of utility/grid interconnection requirements.
• Strong background in Power Systems and High Voltage Engineering.
• Proficiency in design tools (AutoCAD, ETAP, DIgSILENT, PSCAD).
• Knowledge of AIS/GIS technologies and grid codes.
• Familiarity with protection schemes (distance, differential, overcurrent, etc.).
• Strong documentation and coordination skills.
