NABCEP PV Commissioning & Maintenance Specialist™ (PVCMS) Certification Requirements

The NABCEP PV Commissioning & Maintenance Specialist certification is a voluntary certification that provides a set of national standards by which PV Commissioning & Maintenance Specialists with skills and experience can distinguish themselves from their competition. Certification provides a measure of protection to the public by giving them a credential for judging the competency of practitioners. It is not intended to prevent qualified individuals from operating, commissioning, or maintaining PV systems or to replace state licensure requirements.

This certification program provides a pathway for experts at operating, commissioning, and maintaining PV systems to earn a NABCEP Professional Certification. PV Commissioning & Maintenance Specialists are expected to understand and follow a quality-oriented process for achieving, verifying, and documenting the performance of PV systems. Exceptional application of verification protocols and preventive and corrective maintenance operations are key to this Certification.

Certification applicants should read the NABCEP Certification Handbook before starting an application.

PV Commissioning & Maintenance Specialist Job Task Analysis (JTA)

The foundation document for all of the NABCEP Certification Exams is a detailed description of the job and subject matter involved. This is referred to as a “Task Analysis” or “Job Task Analysis (JTA).”

The NABCEP Photovoltaic Specialists JTA defines a set of knowledge, skills, and abilities typically required of PV Professional that specialize in design, installation, or commissioning & maintenance. This comprehensive Job Task Analysis (JTA) contains a detailed listing of the necessary skills and abilities for PV Specialists who perform decision making roles concerning the design, installation and commissioning & maintenance of Photovoltaic (PV) systems. The JTA guides the development of the PV Specialists exams by which candidates for certification can demonstrate that they possess the skills and knowledge that their peers and experts have deemed necessary to do the job well.
