20 Watt Solar Panels

Typical commercial applications of these modules,
which generate peak power of 20 watts and 30 watts
respectively, include remote telemetry, instrumentation
systems, security sensors, land-based
navigation aids, and signals. Also well-suited to small
DC loads on the farm or home, they are easily
mounted to a range of surfaces or structures using
Solarex mounting kits or user-fabricated supports.
The SX-20 and -30 are available in three configurations:
the M configuration, which includes the
versatile MultiMount frame and a 15-foot output
cable; the D configuration, which mounts directly to
many surfaces without additional hardware; and the
U configuration, which includes the heavy-duty
Universal frame and a high-volume junction box with
dual-voltage output.
The SX-20M and SX-30M
The SX-20M and -30M are general-purpose PV modules
suitable for applications compatible with the
MultiMount frame and the modules electrical characteristics.
They are for use in single-module
applications with system DC voltage not exceeding
30 volts.
MultiMount Frame
The MultiMount frame of the SX-20M and -30M
provides tremendous flexibility in mounting approach.
Oriented parallel to the edge and back of
the module, its dual channels accept the heads of
5/16 or 8mm hex bolts, allowing the module to be
mounted from the side or back. Bolts may be located
anywhere along the channels (shown at left with end
caps removed), a configuration which prevents them
from turning during tightening and allows installation
with just one wrench.
Complete, Factory-Wired
Output of the M configuration is via a 15-foot (4.6m)
PVC-jacketed cable which terminates in a low-profile
junction box on the module back. Epoxy-potted in
the box, module electrical connections are sealed
against corrosion and effectively strain-relieved.
Output voltage is compatible with 12VDC systems
