Designed for small to medium off-grid power applications, the SolarTech Power SPM055M-N delivers 55W of clean energy with high-efficiency monocrystalline cells. Featuring a 36-cell configuration, a weather-resistant junction box, and a 900mm pre-attached cable, this panel is ideal for remote power systems, water pumping, telecommunications, lighting, battery charging, and small residential, RV, marine, and commercial DC installations.
Key Features & Benefits
55W Monocrystalline Power Output: Delivers reliable 12V DC power using 36 high-efficiency monocrystalline cells (156mm × 65mm) arranged in a 4×9 series matrix, providing solid performance with 13.2% module efficiency.
12V DC Nominal Output (18.18V Vpm): Perfect for standard 12V off-grid systems, including RVs, boats, cabins, water pumping, and lighting applications.
Pre-Attached 900mm Cable: Comes with a 900mm pre-attached cable from the junction box, simplifying installation and reducing the need for additional wiring.
Durable Construction: Built with high-transmission tempered glass, double-layer EVA encapsulation, and an anodized aluminum frame for long-lasting outdoor performance.
1500V System Voltage: Maximum system voltage of 1500V DC exceeds standard industry ratings, allowing for flexible array configurations in larger off-grid systems.
Wide Operating Temperature Range: Functions reliably in extreme conditions from -40°C to +85°C.
Outstanding Low-Light Performance: Generates power even during dawn, dusk, and overcast conditions, maximizing daily energy harvest.
