Frequently Asked Questions (FAQs)
It uses N-type monocrystalline cells with lower degradation and a 23.5% conversion efficiency, delivering stable power output for 25 years. It is more reliable than standard P-type panels, making it ideal for long-term commercial applications.
Absolutely. Constructed with tempered glass, a corrosion-resistant aluminum frame, and an IP68-rated junction box, it operates reliably across a wide temperature range of -25°C to +65°C, and can withstand strong winds and heavy snow loads for decades of outdoor use.
Installation is highly efficient. Pre-installed MC4 connectors and pre-drilled mounting holes significantly reduce on-site construction time and labor costs for commercial rooftops or off-grid power stations.
It is ideal for small commercial power systems, RV/boat fleets, communication base stations, remote monitoring equipment, and backup power solutions for industrial facilities.
We provide a 25-year performance warranty, including a linear power output guarantee. All products undergo strict quality control and are manufactured under ISO-certified processes.
No. Its advanced low-temperature coefficient technology minimizes efficiency loss at high temperatures, maintaining stable output even in extreme heat — a critical advantage for commercial sites in warm regions.
Yes. We support customizations for large commercial orders, including cable length, connector type, and packaging, to meet the specific requirements of your project.
High-quality Hanwha EVA film enhances UV and moisture resistance, preventing delamination and cell degradation. This ensures the panel maintains stable performance even in humid or coastal environments.
