Product Overview & System Integration

The 595-625W Mono Dual Glass Solar Panel utilizes N-Type TOPCon cell architecture to deliver high-density energy output for utility-scale and large commercial EPC projects. Engineered with a bifacial dual-glass structure, it captures rear-side albedo to provide an additional 10% to 30% power yield depending on ground reflectivity. The module integrates efficiently with standard 1500V DC string inverters and centralized utility inverter stations, minimizing balance of system (BOS) costs. As a direct China manufacturer, we support deep OEM modifications, including custom frame anodizing, specific cable lengths for optimized tracker mounting, and precise junction box positioning. The symmetrical double-glass construction eliminates backsheet degradation risks and guarantees zero PID (Potential Induced Degradation) under extreme temperature and humidity environments.

Quality Control & Global Standards

Manufacturing execution follows ISO 9001 quality management systems. Every 625W module undergoes 100% double EL (Electroluminescence) testing-once before lamination and once after-to detect and eliminate micro-cracks or soldering defects. The series complies with IEC 61215 and IEC 61730 standards, holding active certifications from TUV Rheinland and CE. Standard factory protocols include rigorous mechanical load testing, damp heat testing (85°C/85% RH for 1000+ hours), and UV exposure testing to validate the 30-year design life.

Packaging & Logistics Safety

Modules are secured using vertical portrait packing on reinforced wooden pallets engineered for standard shipping containers. High-density edge protectors, robust steel strapping, and waterproof wrap isolate the glass edges from transit shock. Container loading yields 36 pieces per pallet and 720 pieces per 40HQ container, utilizing heavy-duty bracing bars to prevent shifting during maritime transport.

Typical Application Scenarios

The 595W-625W bifacial output format provides optimized levelized cost of energy (LCOE) for utility-scale solar farms, commercial rooftop installations, agrivoltaics greenhouses, large-scale solar irrigation facilities, and grid-tied industrial microgrids.

FAQ

How does the N-Type 625W module interact with single-axis tracking systems?

The 625W module features optimized mounting hole alignments specifically designed for 1P and 2P single-axis trackers. Its customized 1200mm output cables prevent mechanical tension during maximum tilt angles, ensuring stable 1500V DC transmission across the entire tracking radius.

What is the expected long-term ROI considering the 30-year linear power warranty?

N-Type TOPCon cells restrict first-year degradation to ≤1.0% and annual attenuation to 0.40%. Over a 30-year operational lifecycle, the guaranteed power output remains at 87.4%, providing reliable IRR calculations for large-scale utility PPA financial modeling.

Can the factory adjust the dual-glass thickness for high-snowload regions?

Yes, our standard wholesale configuration uses 2.0mm+2.0mm glass. For deployment in regions exceeding 5400Pa snow load requirements, we upgrade the bill of materials to 2.5mm+2.5mm tempered glass combined with a reinforced 35mm anodized aluminum alloy frame upon request.
