1. Engineering & Design
This group utilizes technical expertise to plan and calculate systems for maximum efficiency.
· Solar Design Engineer: Designs the solar PV systems, calculates panel and inverter sizing, and plans cable routing (often using software like PVSyst or AutoCAD).
· Structural Engineer: Inspects and designs the mounting structures, especially for Solar Rooftop installations, ensuring they can support the weight and withstand wind loads.
· Electrical Engineer: Controls and designs the electrical systems, grid connection, and safety protection systems.
2. Site Survey & Feasibility
Before any installation begins, real-world data must be gathered to assess viability and financial return.
· Site Surveyor: Measures the physical space, checks sun orientation, assesses shading from nearby buildings or trees, and evaluates actual site conditions.
· Project/Financial Analyst: Calculates the Return on Investment (ROI), payback period, and analyzes the overall business feasibility for clients.
3. Installation & Construction
The field-based core of the industry that turns blueprints into functioning power plants.
· Project Manager (PM): Oversees the entire project timeline, budget, resource allocation, and overall execution.
· Site Supervisor/Foreman: Manages the daily on-site work, ensures quality control, and strictly enforces safety standards.
· Solar Installer/Technician:
Structural Team: Installs foundations, mounting racks, and secures the solar panels.
Electrical Team: Handles AC/DC wiring, installs inverter systems, combiner boxes, and grounding systems.
4. Operations & Maintenance (O&M)
Since solar systems have a lifespan of 20–25 years, ongoing care is crucial to maintain peak performance.
· O&M Technician: Conducts routine system checks, measures electrical output, performs thermal scanning for hotspots, and troubleshoots system failures.
· Solar Panel Cleaning Team: Washes away dust, bird droppings, and debris that block sunlight from reaching the cells.
5. Sales, Support & Legal (Permitting)
Because solar installations require strict government and utility approvals, this sector is highly vital.
· Permitting/Regulatory Specialist: Coordinates and submits paperwork for grid-connection permits with electricity authorities (like MEA/PEA in Thailand) and building modification permits with local municipalities.
· Sales & Business Development: Prospects for new clients, provides initial consultations, and drafts project proposals and quotes.
· Procurement Officer: Sources and purchases solar panels, inverters, and components at the best balance of cost and quality.
