Description
The SLD Tech ST-50Q-24 is a 50-watt, 60-cell monocrystalline solar panel delivering 21% module efficiency for reliable 24V DC power in off-grid and small-scale renewable energy applications.
Key Features:
- High-Efficiency Monocrystalline Cells: Advanced cell technology and manufacturing capabilities achieve a 21% module efficiency rating with a 3% positive power tolerance.
- High PID Resistance: Qualified materials and advanced cell engineering deliver strong resistance to Potential Induced Degradation for sustained long-term output stability.
- Heavy-Duty Weather-Resistant Construction: Anodized aluminum frame withstands 5,400 Pa positive load and 2,400 Pa negative load, with salt mist resistance per IEC 61701.
- High-Transparency Tempered Glass: Low-iron tempered glass maximizes light transmission while providing outstanding protection against hail, wind pressure, and heavy snow.
- 10-Year Power Warranty: Backed by a 10-year power output warranty and a 5-year product workmanship warranty for reliable long-term performance assurance.
The ST-50Q-24 is designed for nominal 24V DC output, making it an ideal solution for higher-voltage battery charging, mid-scale off-grid systems, and remote power applications. Its outstanding low-light performance ensures consistent energy generation even under reduced irradiance conditions.
Built with 60 monocrystalline silicon cells in a 5x12 configuration, this panel delivers proven efficiency and structural durability in demanding outdoor environments. The lightweight 7.81 lb design and slim 1.18-inch profile make mounting and installation practical across a wide range of fixed and portable applications.
The ST-50Q-24R with SLCBL-55 includes a pre-installed 10ft 18/2 AWG cable assembly featuring an integrated 3A inline blocking diode and 3/8" ring terminal connectors for direct battery connection.
