3 Array
Design
Zep Solar, Inc. seeks to encourage efficient design of PV arrays by allowing users to design their own systems.
The Zepulator online design tool and Span Tables are available on the Zep Solar web site to enable custom
array designs. Additional information on fine-tuning array designs can be found in training videos, also available
on the Zep Solar web site.
Step 1:
Gather Project Data
Array design begins by identifying specific information that applies to the project, including:
•
Site information such as wind speed/zones, snow load, and terrain characteristics
•
Building characteristics such as rafter/truss spacing, roof pitch, and roof type
•
PV array details such as PV module manufacturer, mounting area size, and desired orien-
tation
Within each specified roof type, users can select a preferred Zep Solar approved roof attachment
when using the Zepulator. The Span Tables and Certification Letters are only valid for hardware
specifically tested and approved by Zep Solar, Inc. for use within each country.
NOTE:
Input variables may vary from one country to the next. To see variables for
other countries supported in the Zepulator, select another country for the proj-
ect on the Project page.
