PV Array Layout Design
Array design is the physical layout of the Solar PV modules
and associate a cabling for modules. Array design with
Enphase IQ8D Microinverter offers flexibility. Each IQ8D
Microinverter can be connected to 2 series connected PV
modules or a single high-power module based on module
compatibility.
Information Required for Array Design
•
Solar module specifications.
•
Type of PV module – Monofacial or Bifacial, 54-
cell/108 half-cell, 60-cell/120 half-cell, 66-cell/132
half-cell and 72-cell/144 half-cell.
•
Available installation area of the proposed location
(including shading, pitch, orientation, roof material/
type, and access).
•
Total number of modules/Microinverters to be
installed.
Optimized Site Layout
•
Site access zones.
•
Setbacks from roof edges.
•
Shading zones.
•
Keep out zones for adjacent obstacles.

You can consider any array configuration, module
orientation, azimuth, and tilt angle for the PV modules.
Please note that IQ8D has a single Maximum Power
point tracking and if connected with 2 series connected
modules; both the panels should have same orientation,
azimuth, and tilt angle for maximizing power output.
Design Considerations for PV Array Layout
•
Site electrical configuration and layout.
•
Structural mounting integrity.
•
Site shade paths.
•
Load bearing capacity of the terrace, rooftop or the
structure on which the PV system is mounted.
•
Typical and maximum wind loads at that location, also
factoring the height of the installation.
•
Site access (access to arrays for maintenance, etc.).
