Solar PV Installer

Key Responsibilities

• Mechanical Assembly & Structural Installation:
• Assemble and anchor Module Mounting Structures (MMS) on RCC roofs, tin/metal sheets, or ground structures as per structural drawings.
• Mount, clamp, and secure solar PV modules with proper torque specifications to prevent panel stress or microcracks.
• Ensure roof water-proofing integrity (chemical anchors, flashings, or grouting) during and after structural fixing.
• Electrical Wiring & BOS Integration:
• Execute DC string cabling from solar modules to combiner boxes/inverters, including neat dressing, UV-resistant cable tying, and conduit routing.
• Terminate MC4 connectors securely using appropriate crimping tools and conduct polarity checks before connection.
• Mount and connect inverters, ACDBs, DCDBs, and LT panels according to Single Line Diagrams (SLD).
• Install earthing systems, including driving chemical earth electrodes, laying copper/GI earthing strips, and connecting surge protection devices (SPD) and lightning arrestors (LA).
• Testing, Commissioning & Quality Assurance:
• Perform pre-commissioning checks: open-circuit voltage ($V_{oc}$), short-circuit current ($I_{sc}$), string continuity, insulation resistance (Megger test), and earth pit resistance.
• Assist the site engineer during system power-on, grid synchronization, and inverter commissioning.
• Label all cables, junction boxes, conduits, and panels according to project standards.
• Preventive Maintenance & Troubleshooting:
• Inspect existing plants for loose terminations, hot spots, tripped breakers, inverter fault codes, or physical panel damage.
• Perform basic module cleaning assessments, string repairs, and equipment component replacements.
• Health, Safety & Environment (HSE):
• Strictly follow site safety protocols, including mandatory use of PPE (safety harness, helmet, safety shoes, insulated gloves).
• Maintain clean, organized work areas and handle tools and equipment safely at heights.

Required Qualifications & Skills

• Education: ITI / Diploma in Electrical, Electronics, or Wireman trade (Solar PV installer certification from NSDC/SCGJ is an advantage).
• Experience: 1–3 years of hands-on experience in rooftop or ground-mount solar PV installation and electrical wiring.
• Technical Competencies:
• Ability to read basic electrical layouts, single-line diagrams, and wiring schematics.
• Proficiency in using crimping tools, torque wrenches, multimeters, clamp meters, and insulation testers.
• Thorough understanding of phase, neutral, earth connections, and AC/DC polarity.
• Physical Requirements:
• Comfortable working outdoors and at heights on ladders, scaffolding, and roofs.
• Ability to lift panels and heavy equipment (up to 20–25 kg).
• Willingness to travel to various regional site locations.
