Role Overview

The Design Engineer will be responsible for end-to-end engineering design of solar PV projects, including AC/DC system design, shadow analysis, and energy estimation using tools like HelioScope and PVsyst. The role involves preparing detailed design layouts, BoM/BoQ, and technical documentation based on site inputs. The individual will work closely with the Project Execution team to understand requirements and ensure accurate and timely delivery of designs.

Experience: Min 2 years of Design experience in the solar field.

Qualification: B.Tech either in electrical, mechanical or instrumentation engineering.

Know-how:

• Should be Proficient in AutoCAD, Google Sketchup, MS Office
• Should be well versed with Solar Design Software HelioScope. Should be able to do Shadow Analysis using Helioscope and PVsyst.
• Energy Estimation and Generation Simulation using PVSyst and should be able to do AC/DC loss calculation and selection of cable, fault calculation of system, Earthing design calculation, Protection schemes, etc.
• BoM Preparation and BoQ preparation of Entire Solar PV Plant based on Detailed Site Survey inputs.
• Design of ACDBs / LT Panels / HT Panels by selecting different switchgear, SPD, meters, and other components.
• Should be able to interpret complex electrical wiring diagrams for LT and HT side, protection schemes, etc. Knowledge of different types of module mounting structures
• Should be able to interpret civil / architectural drawings, elevation drawings, cross-section drawings. Knowledge of STAAD Pro and Structural Design Calculations according to Wind Speed will be an added advantage.
• Having knowledge and exposure of working at site with project execution teams will be an added advantage.

Responsibilities:

• Manage the work of engineering design of different projects, recognize the requirements from the Project Execution team and interact with them on a daily basis regarding the design & engineering concept of the projects in hand.
