Installation Manual
High Efficiency Half-Cell Module
Introduction
This manual contains information about electrical and
mechanical installation of the solar panels: DNA-120 and
DNA-144 Series
Disclaimer of Liability
Installation techniques and methods of this product is
beyond Aptos Solar Technology's control. AST does not
assume responsibility of loss or damage resulting from
improper installation, handling or use. AST disclaims liability
for damage, loss, expense arising out of, or in any way
connected with installation, use or maintenance by using this
manual.
Regulation Information
This certified product meets the UL61730 standard for
maximum system voltage of 1000V with maximum
overcurrent protection rating of 20A. The installer or system
integrator is assumed the responsibility to ensure compliance
with all local electrical codes which may be applicable.
Warnings & Safety
Solar panels generate electricity when exposed to light,
which can cause lethal shock and burn hazards.
Only authorized, qualified and trained installers should
handle these solar panels. Do not touch live terminals
with bare hands. Work only in dry weather with dry solar
panels and tools.
Do not make connections while under load. Do not
disconnect under load. Use insulated tools for electrical
connections. Do not step or stand on the solar panel.
Do not disassemble the solar panel or junction box.
Carry panel with two or more person. Do not carry by its
wires or junction box. Wear non-slip, suitable gloves
and protective clothing.
Do not install the solar panel where flammable vapors
or gases are present. Do not install in corrosive
environment.
Do not direct artificially concentrated sunlight on solar
panel.
Under normal conditions, a photovoltaic module is likely
to experience conditions that produce higher current
and/or voltage than reported at standard test conditions.
Accordingly, the values of Isc and Voc marked on this
PV module should be multiplied by a factor of 1.25
when determining component voltage ratings, conductor
current ratings, and size of controls (e.g., inverter)
connected to the PV output.

The module is considered to be in compliance with this
standard only when the module is either mounted in the
manner specified by the mounting instructions, or when
the mounting means has been evaluated with this PV
module to UL 2703. A module with exposed conductive
parts is considered to be in compliance with this
standard only when it is either electrically grounded in
accordance with the manufacturer's instructions and the
requirements of the National Electrical Code,
ANSI/NFPA 70 (2014-2017), or when the bonding
means has been evaluated with this PV module to UL
2703.
Fire Rating
If mounted over a roof, the solar panel shall be mounted
over a fire-resistant roof covering rated for the
application. Refer to local authority for guidelines and
regulations for building fire protection and required
slope. The module fire performance rating is Type I.
Installing the Panel
Aptos Solar Technology panels may be installed in various
applications. The particular mounting is to be defined by the
system designer. Installer must handle and mount the
modules to prevent any impact on front surface, back surface,
and frames as this could result in damage.
Support structures used to support AST DNA panels
should be wind rated and approved for use by the
appropriate codes prior to installation. In addition, they
must be designed from materials that retain structural
integrity over the 25 years lifespan of the panels they
support.
AST DNA panels may be installed in portraits or
landscape orientation.
A minimum of tilt angle of 5 degrees is required to
ensure drainage and enable rainwater.
The junction box edge should be at the top when
mounted in portrait orientation.
Specific rails and frame clips approved by AST are
listed in Table 1. Alternative rails and frame
clips/fasteners need to be approved by AST to ensure
compliance to UL61730 safety standard.
De-rating factors must be applied if installed above
2000m.
