Maintenance
ASTDNA panels are designed to require little to no
maintenance. Depending on local conditions, panels
may need periodic cleaning to remove dirt build-up and
soiling. Panels should be washed with water to remove
dirt and soiling. Frequency of cleaning will depend on
local weather conditions and panel tilt. Once a year,
have qualified service professional check the general
condition of wiring and check to be sure that mounting
hardware is at the correct torque. Loose connections
may result in damaged panels.
Panels generate electricity when there is sunlight, and
cleaning/maintenance personnel must take proper
precautions.
Mechanical Drawings
Installers must use pre-drilled mounting holes on the
frame.
Frame clip must have minimum height dimension as
shown.
End Frame Clip
Mid Frame Clip
Mounting Methods
Mounting holes are 14mm by 9mm. M8 bolt and
fasteners.
Torque value is 12.5 Nm – 18 Nm.
Rails can run perpendicular or parallel to panel length.

General Information
Slope should be less than 5 in/ft (127 mm/305mm)
required to maintain a fire class rating. Any roof
penetration required to mount the module must be
properly sealed to prevent leaks. The modules are rated
fire class C and are suitable for mounting over class A
roof.
Pole Mount
When installing a module on a pole, choose a pole and
module mounting structure that will withstand
anticipated winds for the area.
Modules Installed with Mounting Holes
Modules should be bolted with M8 and M6 to the
support structures through mounting holes located in
the frame in the back flanges. See table in the following
page. Torque should be 12.5-18 Nm for tightening the
M8 bolt, the torque should be 9-15 Nm for tightening the
M6 bolt.
Modules Installed with Clamping
Modules should be bolted to the support
structures rail by metal clamps. It is recommended
to use clamp under the following conditions or
approved by system installation. Clamping distance
is quarter of the module length. See table in the
following page.
Clamp materials: Aluminum, Bolt torque: 12.5 – 18
NM, clamp must not contact the front glass,
bolt: M8 SS, flat washer: diameter 16-8.4 mm H1.6
ss, spring washer: diameter 12.6-8.4 mm H4.7 ss.
