Designed specifically for 24V off-grid applications, the SolarTech Power SPM045M-WP delivers 45W of clean energy with robust monocrystalline efficiency. Featuring a 68-cell configuration that produces a nominal 24V output, a weather-resistant junction box, and a 900mm cable with MC4 connectors, this panel is ideal for 24V battery charging, remote power systems, telecommunications, water pumping, lighting, and small residential, RV, marine, or commercial DC installations.
Key Features & Benefits
45W Monocrystalline Power Output: Delivers reliable power using 68 monocrystalline silicon cells (156mm × 26mm) arranged in a 4×17 series matrix, providing solid performance with 12.1% module efficiency.
24V Nominal Output (34.2V Vpm): Designed specifically for 24V off-grid systems, delivering an optimal charging voltage for 24V battery banks. The higher voltage also reduces line loss over long wire runs compared to 12V panels.
Pre-Attached MC4 Connectors: Comes with a 900mm pre-attached cable and MC4 connectors, simplifying installation with industry-standard plug-and-play compatibility.
Durable Construction: Built with high-transmission tempered glass, double-layer EVA encapsulation, and an anodized aluminum frame for long-lasting outdoor performance.
1000V System Voltage: Maximum system voltage of 1000V DC allows for flexible array configurations with multiple panels in series for larger 24V 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.
