Description
The SLD Tech (Solarland) ST-90Q-24 is a 90-watt, 66-cell monocrystalline solar panel delivering 21.4% module efficiency for reliable 24V DC power in off-grid and renewable energy applications.
Key Features:
- High-Efficiency Monocrystalline Cells: Advanced cell technology and manufacturing capabilities achieve a 21.4% 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.
- 25-Year Power Warranty: Backed by a 25-year power output warranty and a 5-year product workmanship warranty for reliable long-term performance assurance.
The ST-90Q-24 is designed for nominal 24V DC output, making it a strong solution for battery charging, mid-scale off-grid systems, and remote power applications requiring higher wattage.
Built with 66 monocrystalline silicon cells in a 3x22 configuration, this panel delivers proven efficiency and structural durability in demanding outdoor environments. The 12.76 lb design and slim 1.18-inch profile make mounting and installation practical across a wide range of fixed applications.
With an operating temperature range of -40°C to 65°C and a maximum system voltage of 1000V DC, the ST-90Q-24 is engineered to perform reliably across a broad range of climates and system configurations.
