Career tips
- Build a portfolio: keep your PVsyst reports, AutoCAD layouts and project files ready to show.
- Learn the site side: employers value people who know how installation, earthing and commissioning really work.
- Get certified: recognised certificates (for example from SCGJ) help for solar roles.
- Practise interviews: revise basics — Ohm's law, power factor, MCB vs RCCB, string sizing — they come up often.
- Keep your CV to one page with software skills, projects and site experience.
Jobs and placement support
Roles our learners prepare for: solar design engineer, site / installation engineer, PLC and automation technician, electrical maintenance engineer, estimation and BOQ engineer.
