After the labs, you know which exam to book
- After the labs, you know which exam to book. Prep here for EPRA, NABCEP, EPA 608, NATE, CEC, SAQCC Gas and ESSCI, then book with that body when the labs are done.
- EcoPowerHub Academy is the prep and issues its own completion record. The examining body is the issuer of the credential you sit for.
- Work on photovoltaic, battery, and electrical systems involves potentially lethal voltages and must only be performed by qualified persons, in accordance with applicable codes, regulations, and employer safety programs.
- Labs and materials are educational. The technician and their employer remain solely responsible for safe work practices, isolation, PPE, and compliance on actual jobs.
- Exam and licence fees are paid to the examining body. Academy completion is training.
