BP SX 50W Solar Kit Specifications

BP® SX™ 50 photovoltaic modules are part of BP® Solar’s SX™ module series, providing cost-effective photovoltaic power for DC loads with moderate energy requirements. With 36 multicrystalline cells in series, they charge batteries efficiently in virtually any climate. Typical commercial applications of these modules, which generate nominal maximum power of 50 watts, include remote telemetry, instrumentation systems, security sensors, and land-based navigation aids. They are also well-suited to providing subsistence power to homes in remote areas without utility (mains) service.

Proven Materials and Construction
BP Solar’s quarter-century of field experience shows in every aspect of SX-50U construction and materials:

36 multicrystalline silicon solar cells in series

Frame strength exceeds requirements of certifying agencies

Cells are laminated between sheets of ethylene vinyl acetate (EVA) and high-transmissivity low-iron 3mm tempered glass.

Specifications
Weight: 13.9 lbs. (6.3 kg)
Size: 19.75" x 36.97" x 1.97" (502mm x 939mm x 50mm)

Output
High-Capacity Versatile Junction Box
The junction box is raintight (IP54 rated) and accepts PG13.5 or 1/2” nominal conduit or cable fittings. Its volume (411cc, 25 cubic inches) and 6-terminal connection block enable most system array connections (putting modules in series or parallel) to be made right in the junction box.

Quality and Safety

Manufactured in ISO 9001-certified factories

Listed by Underwriter’s Laboratories for electrical and fire safety (Class C fire rating)

Certified by TÜV Rheinland as Class II equipment and for use in systems with voltage up to 1000 VDC

Approved by Factory Mutual Research for application in NEC Class 1, Division 2, Groups C & D hazardous locations

Complies with the requirements of IEC 61215, including:

repetitive cycling between -40°C and 85°C at 85% relative humidity

simulated impact of 25mm (one-inch) hail at terminal velocity

a “damp heat” test, consisting of 1000 hours of exposure to 85°C and 85% relative humidity

a “hot-spot” test, which determines a module’s ability to tolerate localized shadowing (which can cause reverse-biased operation and localized heating)

static loading, front and back, of 2400 pascals (50 psf)

front loading (e.g. snow) of 5400 pascals (113 psf).

Limited Warranties

Power output for 20 years

Freedom from defects in materials and workmanship for 1 years. See Warranty Information Sheet for more details.
