About the role
A solar installation technician sizes, installs and commissions solar systems with panels, inverters and batteries for homes and businesses. With frequent power cuts, demand is strong. The interviewer is deciding whether you understand the basics of sizing, work safely on roofs and leave customers knowing how to use their system.
How to prepare
- Practise working out a simple load estimate and the system size it needs from a list of appliances.
- Be ready to explain how panels, charge controllers, inverters and batteries fit together.
- Review safe working at height and how you protect yourself and others on a roof.
- Think about how you explain battery care and system limits to a customer at handover.
- Prepare an example of an installation you worked on and any problem you had to solve on site.
Common mistakes
- Promising customers more power than the system can deliver.
- Not being able to explain how you sized a system, which suggests guesswork.
- Treating safety at height lightly because the roof looks easy.
