Existing and new panel amperage ratings (buss ratings).

Series and parallel configuration of the module connections.

Labeling diagram.

Equipment Requirements

Provide product listing sheets for all equipment with the following information:

Module short circuit current ratings. 0 Module open circuit voltage ratings. 0 Module series fuse ratings.

Inverter output circuit current rating.

Inverter UL listings.

Panels

Roof Mounted Panels

Provide the Following Information:

An Engineer’s evaluation regarding the dead-load capability of the existing roof structure and its 

ability to support the added weight of the solar photovoltaic system. The Engineer must reference the 

required wind and snow load for the site. If the panels project above the ridge line of the roof, this 

most also be part of engineers evaluation.

For flat roof installations provide method of repair for roof penetrations.

Pole or Ground Mounted Panels

Provide The Following Information:

Site Plan to include the following:

Location of panel(s) on property.

Dimensions from panel(s) to property lines.

Dimensions from panel(s) to other structures on the property and property easements.

Engineered footing design
