PV System Checklist
The PV System Installation Checklist is an important tool used to verify comple-
tion of all aspects of the installation. As you read earlier, proper installation is the
key to optimal performance. The main purpose of the checklist for most integra-
tors is to simplify the installation of safe PV systems at the least possible cost. An
effective list will result in the least amount of effort for the inspector and installer.
A comprehensive list also can aid in improving system output and reducing oper-
ations and maintenance costs.
The PV system checklist should include the following information:
Customer, architect, electrician, designer, roofer, and builder
contact information
Customer wishes and expectations on PV module setup and energy yield
Construction plans
Illustration of PV site with shading objects such as chimneys, trees, power
lines, etc.
Roof and building measurements
List of any roof elements such as chimneys, antennas, skylights, or dormers
Roof shape, construction, and covering
There are a variety of checklists in this book for you to use or modify.
Generators, Inverters, and Meters
The checklist of generators, inverters, and meters requires detailed information.
It asks for the orientation and tilt angle of the PV array. The orientation can be
from −90 degrees east via 0 degrees south to +90 degrees west. The tilt angle can
be from 0 degrees to 90 degrees (horizontal to vertical).
The checklist asks for information on lightning protection and placement for
the PV array, inverter, disconnects, and other components. It documents the loca-
tions for the following components:
Combiner box for the PV array (which allows you to bring together in a
number of strings, combine them, and reduce the number of conductors
going to the DC disconnect and inverter.)
The array
Inverter
Customer’s service entrance section, or SES (sometimes known as the
service entrance switchboard)—the electrical panel board on a site where PV
equipment and other electrical loads or mechanisms connect to the grid or
other energy supplied to the site.
