SPR-E-FLEX-50
SunPower's flexible solar panels are equipped with high power Gen II back contact cells, offering the highest power output and charging capacity in their class. Constructed with lightweight polymer materials, these panels are easy to transport and install, with the ability to flex up to 30 degrees.
The Maxeon® Solar Cell, built on a solid copper foundation, ensures resistance to power loss from cracking and corrosion, making SunPower panels a preferred choice for their combination of power and durability.
Installation is straightforward with adhesives or stainless steel grommets, and panels come with quick-connect cables and an installation guide. A 5-year limited power warranty guarantees 80% of the minimum specified power rating.
At standard test conditions (STC: 25° C, 1000 W/m2, AM 1.5), the SPR-E-Flex-50 model offers:
- Nominal Power: 50 W
- Power Tolerance: +/-5%
- Rated Voltage: 17.7 V
- Rated Current: 2.8 A
- Open-circuit Voltage: 21.5 V
- Short-circuit Current: 3.1 A
- Power Temp Coefficient: -0.35%/° C
- Voltage Temp Coefficient: -58.9 mV/° C
- Current Temp Coefficient: 2.6 mA/° C
- Max. System Voltage: 45 V
- Series Fuse Rating: 15 A
The panels use prime monocrystalline 23% efficiency SunPower IBC cells, with a junction box featuring a by-pass diode. Connectors are PV4-S, compatible with MC4, and cables are 450 mm long. The panel dimensions are 653 x 556 x 20 mm with the junction box, weighing 2.4 lb (1.1 kg).
Designed in the USA and assembled in the Philippines, these panels are covered by SunPower's trademarks. Specifications are subject to change without notice.
