Lead / Principal Solar Electrical Design Engineer (Ground-Mount & MV/HV Systems)
Location: Hyderabad
Job Type: Full time
Experience Level: Senior / Lead (8–12+ Years)
Industry: Renewable Energy / Utility-Scale Solar EPC

About the Role
We are searching for a seasoned, hands-on Lead Solar Electrical Design Engineer to take complete ownership of electrical design execution for multi-MW utility-scale ground-mount solar PV projects.

This is not a high-level administrative or purely supervisory role. We need an engineer who built their foundation by physically designing plants—drafting Single Line Diagrams (SLDs), running PVsyst models, sizing cables, and calculating ground grids—and who now brings that deep technical expertise to lead end-to-end electrical design execution.

The ideal candidate possesses deep expertise across both AC and DC engineering, along with hands-on experience in 11kV, 33kV, and higher EHV power evacuation networks.

Key Responsibilities

End-to-End Design Execution:



Own the complete electrical design lifecycle for utility-scale ground-mount solar projects—from preliminary engineering and DC/AC optimization to detailed design, vendor evaluation, and commissioning support.

Hands-On Engineering & Calculations: Personally perform and review critical design deliverables, including:

Short-circuit, load flow, and voltage drop calculations.

Cable sizing (DC, LT, MV, HV) and thermal rating analysis.

Earthing grid design, soil resistivity analysis, and lightning protection.

DC System Design: Optimize DC field layouts, inverter loading ratios (DC/AC), string sizing, combiner box configurations, DC cable routing, and surge protection.

AC & High-Voltage System Design:

Design robust AC collection systems, inverter duty transformers, 11kV / 33kV MV switchgears, and auxiliary power distribution.

Oversee grid interconnection engineering for 33kV, 66kV, 132kV, or 220kV+ substations/switchyards, including SLDs, protection & metering schemes, and relay coo
