SunPower SPR-E-Flex Flexible Solar Panel (50W & 95W)

The SunPower SPR-E-Flex series delivers exceptional power in a slim, lightweight, and highly durable format—designed for marine, RV, and off-grid applications where space is limited and performance matters. Built with high-efficiency Maxeon Gen II solar cells, these panels offer superior energy yield even in low-light or high-temperature conditions.

Each panel features a rugged, weather-resistant construction with the flexibility to conform to curved surfaces like boat decks, biminis, RV roofs, and more. MC4-compatible connectors and integrated stainless steel grommets ensure quick, secure installation.

Key Features:

• High-efficiency Maxeon Gen II back-contact solar cells (up to 23% efficiency)

• Flexible design accommodates up to a 30-degree bend radius

• Marine-grade durability with IP67-rated junction box and UV-resistant encapsulation

• Ultra-thin (0.13") and lightweight construction for easy installation

• 12 AWG cables with MC4-compatible connectors (17.7" length)

• Backed by a 5-year power output warranty (≥80%) and a 2-year product warranty

SPR‑E‑Flex‑50W (50-Watt Panel):

• Rated Power (Pmax): 50 W ±3%

• Voltage at Max Power (Vmp): 17.7 V

• Current at Max Power (Imp): 2.8 A

• Open Circuit Voltage (Voc): 21.5 V

• Short Circuit Current (Isc): 3.1 A

• Maximum System Voltage: 45 V

• Series Fuse Rating: 15 A

• Dimensions: 25.5 in x 21.9 in x 0.13 in

• Weight: 2.4 lb (1.1 kg)

• Mounting: 4 stainless steel grommets

SPR‑E‑Flex‑95W (95-Watt Panel):

• Rated Power (Pmax): 95 W ±5%

• Voltage at Max Power (Vmp): ~16.5 V

• Current at Max Power (Imp): ~5.7 A

• Open Circuit Voltage (Voc): ~20.0 V

• Short Circuit Current (Isc): ~6.2 A

• Maximum System Voltage: 45 V

• Series Fuse Rating: 15 A

• Dimensions: approximately 48 in x 22 in x 0.13 in

• Weight: approximately 4 lb

• Mounting: 4 stainless steel grommets

Both panels share a temperature coefficient of –0.35%/°C (power) and come with 17.7″ 12 AWG cables and MC4-compatible connectors. Mount with the stainless steel grommets or marine adhesive; the panel's flex helps it contour to curved surfaces. Pair with an MPPT or PWM charge controller rated above the panel's output.

Recommended Applications:

• Charging 12V battery systems on sailboats, RVs, camper vans, and off-grid structures

• Ideal for curved or irregular surfaces where rigid panels are impractical

• Primary or supplemental solar charging in harsh outdoor environments

Warranty

The SPR-E-Flex modules are covered by a SunPower limited warranty: at least 80% of rated power output for 5 years, plus a 2-year product warranty against defects in materials and workmanship.
