For large-volume OEM orders, our standard lead time is 4-6 weeks ex-works Dongguan, which can be optimized based on project urgency and component availability. We pride ourselves on the agility of our Dongguan-based supply chain. Regarding support, we provide comprehensive technical documentation, including datasheets, CAD drawings, and system design guidelines. For key projects, we can arrange for our engineering specialists to offer remote or on-site consultation during the critical design and grid-connection phases to ensure optimal performance.

Yes, customization is a cornerstone of our BIPV solutions through our dedicated Integrated Systems Lab. We can work with architects and developers to produce photovoltaic modules in non-standard dimensions, various frame and backsheet colors (e.g., black, bronze, grey), and even with certain levels of transparency. This ensures the solar elements meet both aesthetic and functional design requirements. The process begins with a collaborative consultation to define technical parameters and design intent.

The primary difference lies in efficiency and performance. Our monocrystalline PERC modules offer excellent reliability and efficiency (typically over 22.5%), ideal for most commercial and utility-scale projects with standard requirements. Our N-type TOPCon modules represent the next generation, with even higher efficiency (over 24.8%), better performance in high temperatures, and lower degradation over time. They are the optimal choice for projects with limited space, high energy yield targets, or in hotter climates. Our sales team can provide a detailed cost-benefit analysis based on your specific site conditions and financial model.
