Description
The SLD Tech ST-255Q-24CID2-QC is a 255-watt, 24-volt monocrystalline solar panel specifically engineered and certified for use in Class I, Division 2 hazardous locations where explosive gas atmospheres may be present (Groups A, B, C, and D). This C1D2-certified module is designed to provide constant pressure on power delivery in demanding industrial environments where safety, reliability, and compliance with NFPA 70 (National Electrical Code) and NFPA 496 standards are absolutely critical. Featuring 72 high-efficiency monocrystalline silicon solar cells arranged in a 4×18 configuration, the ST-255Q-24CID2-QC achieves a module efficiency of 22.0% — ensuring maximum power generation while maintaining enhanced safety features that minimize ignition risks in volatile atmospheres. With a positive power tolerance of 0 to +3%, every panel is guaranteed to produce at least 255W and may deliver up to 262.65W under standard test conditions.

- 255W High-Power Output for 24V Systems — Highest-power C1D2-certified 24V panel, ideal for critical industrial applications
- Enhanced Safety Design — Specialized construction elements minimize ignition risk, meeting NFPA 70 (NEC) and NFPA 496 safety standards
- 22.0% Module Efficiency — Premium monocrystalline cells deliver maximum power per square foot
- High Current Output (6.28A) — Reliable battery charging for 24V systems in hazardous environments
- Extended Warranties — 10-year workmanship / 25-year linear power warranty
- Temperature Code T3C — Rated for operation in environments with ignition temperatures down to 160°C
The 67.9" × 30.24" × 1.57" form factor and moderate 33.46 lb weight make the ST-255Q-24CID2-QC ideal for hazardous location applications requiring high-power 24V solar energy: oil and gas production facilities (wellheads, pipelines, remote monitoring); chemical processing plants and refineries; industrial facilities with explosive gas risks; petroleum storage and distribution sites; remote SCADA systems in hazardous environments; telecommunications sites in volatile atmospheres; commercial trucks and heavy equipment in explosive gas zones; and any application requiring NEC-compliant high-power solar charging in Class I, Division 2 locations.
Its nominal 24V DC output (40.59V Vmp, 47.09V Voc) is optimized for charging 24V battery banks with standard MPPT charge controllers, and the 6.28A current output provides reliable charging for critical backup power systems in hazardous industrial environments.
Built for durability in both harsh outdoor environments and hazardous industrial settings, the ST-255Q-24CID2-QC combines a heavy-duty anodized aluminum frame with high-transparency, low-iron tempered glass to deliver long-term reliability in extreme conditions. The panel is engineered to withstand wind loads up to 2400 Pa (negative) and snow loads up to 5400 Pa (positive), and features specialized design elements that adhere to C1D2 certification standards for minimizing ignition risks.
The module is rated for operating temperatures from -40°C to 65°C and carries a maximum system voltage rating of 600V DC for C1D2 applications. Advanced cell technology and qualified materials provide high resistance to Potential Induced Degradation (PID), ensuring the panel maintains its performance over decades while meeting the stringent safety requirements of hazardous location installations.
