The MSX-50 is a midsize photovoltaic module in Solarex's
Megamodule™ series, a product line which is the industry
standard for reliability, durability and value. It is well-suited
to applications requiring the ruggedness and other premium
characteristics—such as the 20-year warranty—of Solarex’s
larger MSX modules, but needing 50 watts peak output.
Typical uses include remote habitations, instrumentation
systems, security sensors, and navigation aids.
With 36 polycrystalline silicon solar cells in series, the MSX-
50 charges batteries efficiently in virtually any climate. It
may be used in single-module arrays or
deployed in multiple-module
arrays, wired in series/parallel
combinations as required to
meet current and voltage
requirements. The MSX-50 is
engineered under Solarex’s
IntegraSystem™ system integra-
tion concept, which ensures
full compatibility with other
Solarex subsystems and com-
ponents (support hardware,
regulators, etc.) and easy sys-
tem assembly.
Individually Tested,
Labeled and Warranted
As part of the final inspection
procedure, every MSX module
is tested in a solar simulator
and labeled with its actual out-
put—voltage, current, and
power at maximum power
point (P_max)—at Standard
Test Conditions and Standard
Operating Conditions.
Furthermore, the MSX-50 is
covered by our industry-lead-
ing limited warranty, which
guarantees:
• that no module will generate less than its guaranteed
minimum P_max when purchased;
• at least 80% of the guaranteed minimum P_max for
twenty years.
Contact Solarex's Marketing Department for full terms and
limitations of this unparalleled warranty.
Reliable and Versatile
The Megamodule series has proved its reliability at thou-
sands of installations in every climate on Earth. Among the
features that contribute to its versatility:
Dual Voltage Capability
These modules consist of 36 polycrystalline silicon solar
cells electrically configured as two series strings of 18
cells each. The strings terminate in the junction box on
the module back. Shipped in 12V configuration, modules
may easily be switched to 6V configuration in the field by
moving leads in the junction box. This design also allows
installation of bypass diodes on 18-cell strings, which can
improve reliability and performance in systems with nom-
inal voltage 24V and above.
High-Capacity Multifunction Junction Box
The size of the junction box (25 cubic inches, 411cc) and
its six-terminal connection block allow most system array
connections (putting multiple modules in series or paral-
lel) to be made right in the J-box. The box also can
accommodate bypass or blocking diodes or a small regula-
tor. In many instances, this saves the expense and labor
of fitting additional boxes. The box is raintight (IP54
rated) and accepts 1/2" nominal or PG13.5 conduit or
cable fittings. The standard terminals accept wire as large
as AWG #10 (6mm²); an optional terminal block accepts
wire up to AWG #4 (25mm²). Both blocks accept pre-
formed terminations or bare wire.
Proven Materials and Construction
Megamodule materials reflect Solarex's quarter-century of
experience with solar modules and systems installed in virtu-
ally 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)
and tempered glass with a durable Tedlar backsheet.
• Tempered glass superstrate is highly light-transmissive
(low iron content), stable, and impact-resistant.
• Corrosion-resistant, bronze-anodized extruded aluminum
frame is strong, attractive, compatible with Solarex
mounting hardware and most other mounting structures.
Safety Approved
The MSX-50 module is listed by
Underwriter's Laboratories for electrical and
fire safety (Class C fire rating), certi-
fied by TUV Rheinland as Class II
equipment, and approved by Factory
Mutual Research for application in
NEC Class 1, Division 2, Group C & D haz-
ardous locations.
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.
