MSX-Lite modules, part of Solarex’s Megamodule
series, are designed for applications requiring a combina-
tion of light weight, compactness, and ruggedness. They
are particularly useful as 12VDC power sources for expe-
ditions, mobile communications, recreational vehicles
and railroad signaling devices.
Four models of MSX-Lite are available, the MSX-5 Lite,
MSX-10 Lite, MSX-20 Lite and the MSX-30 Lite, delivering
typical peak power of 4.5, 10, 20, and 30 watts respec-
tively at Standard Test Conditions (STC). They are intend-
ed primarily for use in single-module power systems, but
may be interconnected—up to a 30V nominal limit—to
provide increased voltage or current.
Individually Tested, Labeled
and Warranted
As part of the final inspection procedure, every MSX-Lite
module is tested in a solar simulator and labeled with its
actual output—voltage, current, and power at maximum
power point (P
max
)—at Standard Test Conditions and
Standard Operating Conditions. Furthermore, Solarex
guarantees:
that no module will generate less than its guaranteed
minimum P
max
when purchased;
at least 90% of the guaranteed minimum P
max
for
five years.

Proven Materials and Construction
The materials used in these modules reflect Solarex’ two
decades of experience with solar modules and systems
installed in virtually every climate on Earth.
Polycrystalline silicon solar cells: efficient,
attractive, stable.
Modules are rugged and weatherproof: cell strings are
laminated between sheets of ethylene vinyl acetate
(EVA) with a stainless steel substrate and Tedlar cover.
MSX-Lite
Photovoltaic Modules
Proven cell interconnection technique and
moisture-resistant metallization ensure electrical
integrity in severe climates.
Light, Rugged, Easily Mounted
Although extremely rugged, MSX-Lite modules are
compact and lightweight. The largest, the MSX-30 Lite,
weighs only 61/2 pounds (3 kg). The modules may be
mounted from front or back through four grommet-
finished holes which accept fasteners up to 0.2" (5mm)
diameter. Total module thickness is only 16 mm, includ-
ing the mounting grommets and the low-profile output
termination box. The termination box is on the mod-
ule’s front, facilitating mounting on flat surfaces.
MSX-Lite modules can also be mounted on curved
surfaces: they will conform to curvature up to 1
inch per foot.
Ample Charging Voltage
With 36 cells in series, MSX-Lite modules generate
sufficient voltage to charge 12V batteries in virtually
any climate, as shown by the electrical characteris-
tics on the reverse of this sheet.
Solarex Quality
MSX-Lite modules are tested and inspected in our ISO
9001-certified factories to demanding specifications.
Variables Affecting Performance
The performance of typical MSX-Lite modules is
described by the I-V (current/voltage) curves and electri-
cal characteristics table on the reverse side. Each mod-
ule’s actual, tested output characteristics are printed
on its label.
Options
MSX-Lite modules may be ordered with an integral block-
ing diode, which prevents battery discharge at night or
during periods of poor insolation.

A N N I V E R S A R Y
More than 20 years ago, Solarex made the first polycrys-
talline silicon solar cell, advancing photovoltaics beyond the
first-generation monocrystalline technology developed for
electronics. Developed specifically for
photovoltaics, polycrystalline silicon is
used in Solarex's Mega series to
provide a wide range of attractive,
efficient modules. They require
substantially less energy to
manufacture and generate
substantially more energy per rated
watt than other crystalline silicon modules.
