NABCEP PV Installation Professional Job Task Analysis
Introduction
This document presents a comprehensive Job Task Analysis
(JTA) for individuals who perform responsible decision
making roles with respect to the design, installation
and commissioning of Photovoltaic (PV) systems. It is
important to note that the tasks outlined in this JTA are
applicable to a range of installation personnel including
but not limited to: installers; project managers; installation
foreman/supervisor, and designers. The common thread
between these individuals is that they will need to be fully
conversant with and able to apply the knowledge areas
contained in this document.
This JTA introduces a broadening of the scope and
definition of the previously used term “PV Installer” and
is reflective of the evolution of job roles and responsibilities
in the Photovoltaic Installation industry. The industry
has grown and matured over the past decade and this
document reflects these changes in job roles. It is important
to note that while the range of personnel that hold
responsible roles in the PV installation industry has evolved
the basic knowledge areas contained in the JTA remain
fairly constant.
Job Description
for NABCEP Certified
PV Installation Professional
Given a potential site for a solar photovoltaic
system installation and given basic
This task list assumes the NABCEP Certified PV Installation
Professional starts with a system design package, complete
with major components, manufacturer installation manuals,
system schematics, and assembly and troubleshooting
instructions. Even if the NABCEP Certified PV Installation
Professional was responsible for the design of the system
this JTA begins with the step of verifying the accuracy of
the design. Likewise if the personnel did not design the
system he or she must be fully knowledgeable about
systems design, as he or she may be required to adapt
the design to fit a particular application or customer need.
While these tasks described in this JTA have been
developed based on conventional designs, equipment,
and practice used in the industry today, they do not seek
to limit or restrict innovative equipment, designs, or
installation practice in any manner. As with any developing
technology, it is fully expected that the skills required of
the practitioner will develop and change over time as new
materials, techniques, codes, and standards evolve.

instructions, major components, schematics,
and drawings, the NABCEP Certified PV
Installation Professional will: specify, adapt,
implement, configure, install, inspect, and
maintain any type of photovoltaic system,
including grid-connected and stand-alone
systems with or without battery storage, that
meet the performance and reliability needs of
customers in the United States and Canada, by
ensuring quality craftsmanship and compliance
with all applicable codes, standards, and safety
requirements.
Task Steps and Knowledge in each Category Level
CATEGORY / LEVEL
DESCRIPTION
l Critical
Absolutely essential for a PV installer. Installers do these tasks most frequently.
l Important
Very important, but not of the highest level of criticality. These tasks are done
with less frequency by installers yet have been identified as important to
the knowledge base of installers.
l Useful
Might be useful; can inform education and training to add richness and depth.
Installers do these tasks infrequently.
Scope of Job Task Analysis
most if not all PV installations. It is further expected that
all individuals who achieve NABCEP PV Installation
Professional Certification will be familiar with all the
tasks described as “important.” These tasks may not be
performed on all installations but are an important part
of the certified installer’s body of knowledge. Those
tasks that are described as “useful” are performed more
infrequently by the certified installer and are listed in
the Job Task Analysis primarily for the benefit of those
wishing to ensure they have the broadest possible
knowledge of the tasks associated with PV Installations.
NABCEP Certified PV Installation Professionals work in
a variety of responsible roles on PV installation jobs. He
or she fulfills a decision-making role that helps ensure
the quality and serviceability of the PV installation. The
scope of the JTA is such that Certified PV Installation
professionals fill a wide range of job positions within
the industry, taking responsibility for installations of
varying size and complexity. As such, the scope of
their duties may vary considerably. Due to the range
of responsibilities and skills that may fall within
the scope of a NABCEP Certified PV Installation
Professional’s job duties, this Job Task Analysis is very
broad in scope: not all certificants will perform all the
tasks described herein.
Candidates preparing for examination and educators
developing curriculum should be aware that those
questions regarding tasks described as “critical” are most
likely to be included in examinations; tasks described
as “important” may be on the examination; and those
described as “useful” are least likely to be included as
examination questions.
It is expected that all individuals who achieve NABCEP
PV Installation Professional Certification will be familiar
with and capable of executing all the tasks described
as “critical” and that these tasks will be common to
