Điểm giao giữa các vai là nơi dễ rơi việc nhất. Báo cáo khảo sát thiếu thông tin → thiết kế sai. Hồ sơ thiết kế khó hiểu → thi công chỉnh bừa. Một đội tốt không chỉ giỏi từng vai mà còn bàn giao rõ ràng: mỗi đầu ra phải đủ để vai kế tiếp làm việc mà không phải đoán.Handover interfaces are where things most easily fall through the cracks. An incomplete survey report → bad design. Unclear design package → installers improvise. A good team is not only skilled within each role but also hands over clearly: every deliverable must be complete enough for the next role to work without guessing.
Hiểu bốn vai giúp người kinh doanh tư vấn đúng người cho khách và đặt kỳ vọng đúng. Khi khách hỏi ai chịu trách nhiệm phần nào, trả lời rõ ràng theo bốn vai cho thấy công ty có quy trình chuyên nghiệp, không phải một người làm tất cả qua loa.Understanding four roles helps Sales direct the right person to the customer and set correct expectations. When a customer asks who is responsible for what, answering clearly by role shows the company runs a professional process, not one person doing everything loosely.
A project’s four phases require four specialized roles, each with distinct responsibilities and skills. This document describes those four roles (survey technician, designer, installation technician, and O&M technician) to help newcomers choose a career path and help managers build and train their teams.
For: newcomers choosing a role, hiring and training managers, technicians who want to understand adjacent roles for better coordination.
Quick Summary
Four roles follow in sequence across four project phases. The survey technician visits the site and proposes a solution; the designer turns survey data into a complete system on paper; the installation technician physically builds the system; the O&M technician keeps it running reliably over the long term.
All four roles share a common foundation in electrical and solar knowledge, then each adds its own specialist skills: from communication and measurement, to design software, to installation craft, to fault analysis.
Understanding the boundaries and handover points between roles helps a team coordinate smoothly, because the output of one role is the input of the next.
Survey Technician
The survey technician visits the site, performs technical assessments, and proposes the most suitable solution. Responsibilities include surveying the roof and mounting location, assessing the existing electrical installation, taking measurements and making preliminary calculations for panel count and string layout, checking construction safety conditions, developing the technical proposal, and producing a report with a bill of materials.
Required skills include DC and AC electrical knowledge, an understanding of panels, inverters, and strings, the ability to read drawings and perform basic measurements, analytical skills for selecting the right solution, and (especially important) communication skills since this role interacts with clients directly. Typical tools include a laser distance meter, tape measure, clamp meter, multimeter, and full personal protective equipment (PPE).
Designer
The designer converts survey data into a complete solar system on paper. Responsibilities include designing the panel layout to maximize usable area and avoid shading, designing the electrical system (string configuration, inverter selection, and protective devices), performing technical calculations for voltage, current, and voltage drop, drawing the single-line diagram, producing the bill of materials, and providing technical support to the installation team.
Required skills include deep electrical and solar knowledge, proficiency with design software (AutoCAD for schematic drawings, SketchUp for layout modeling, PVsyst for yield simulation, and Excel for calculations and cost estimates), as well as precise calculation skills to prevent overcurrent and overvoltage, and a practical understanding of installation so designs are easy to build.
Installation Technician
The installation technician physically builds the system on the roof. Responsibilities include mechanical installation of the racking and panels (ensuring structural integrity and weatherproofing), wiring and electrical connections per the schematic, installing the inverter, distribution board, and protective devices, commissioning and functional testing, client handover and user instruction, and maintaining occupational safety throughout.
Required skills include understanding system principles and reading electrical diagrams, installation and wiring craft (neat and secure), measurement skills for fault detection, basic troubleshooting, teamwork, safe working at height, and discipline and accountability. Tools include a drill, pliers, measuring instruments, ladder, torque wrench, and complete PPE.
O&M Technician
The O&M technician keeps the system running reliably over the long term after installation. Responsibilities include monitoring the system through a monitoring application to detect faults early, performing scheduled equipment inspections, cleaning panels, checking electrical safety (hot spots and leakage current), troubleshooting faults, and producing operational reports.
Required skills include electrical and solar knowledge, inspection and fault-finding skills using measuring instruments, proficiency with remote monitoring applications, and analytical skills to determine why yield has dropped or why a battery is discharging faster than expected. Tools include a multimeter, clamp meter, insulation resistance tester, computer or smartphone, panel cleaning equipment, and PPE.
| Role | One-line definition | Characteristic skills |
|---|---|---|
| Survey technician | Visits site, proposes solution | Communication, measurement, analysis |
| Designer | Turns survey into a complete system | Design software, calculations |
| Installation technician | Builds the system safely | Installation craft, working at height |
| O&M technician | Keeps system stable long-term | Fault analysis, monitoring |
The handover points between roles are where work is most likely to fall through the cracks. The survey technician hands the report to the designer, so incomplete reports lead to incorrect designs. The designer hands the documentation to the installation technician, so hard-to-follow documents lead to improvised field changes. A high-performing team is not just individually skilled: it also delivers clear handovers between roles, with each output complete enough that the next role can work without guessing.
Understanding the four roles helps salespeople point clients to the right contact and set accurate expectations. When a client asks who is responsible for which part of the project, answering clearly by role demonstrates that the company operates a professional process, not a one-person, catch-all operation.
