NUUKO applies strict quality control throughout product design, manufacturing, testing, and delivery. Our solar modules and energy storage systems are developed with advanced technologies, reliable components, and multiple safety protection features. They have obtained internationally recognized certifications including UL, TÜV, CE, IEC, and CB, comply with ISO quality management standards, and are backed by multiple utility model patents.

Inside the factory, quality is built into the process, not inspected in at the end. Every PV module goes through stringing, lamination, EL testing, and flash testing on automated production lines; every storage system moves from cell sorting to final pack testing under whole-process control, with raw material testing at the intake stage. The results are measurable: module efficiency up to 23.2%, a 12-year product warranty and 30-year linear power warranty on our panels, and multi-level safety protection with integrated BMS on every storage system. Reliability, for NUUKO, is an engineered outcome, not a promise.

Yes. NUUKO provides professional OEM/ODM energy storage services for global distributors, EPC companies, and energy solution providers. We support customized branding, product labeling, packaging, technical documentation, and market-specific solutions to help partners develop their own energy storage products under their own name.

What makes our OEM/ODM dependable is the manufacturing behind it: from cell sorting to final pack testing, every step happens in our own facility, so quality is never outsourced. We configure capacity, voltage, appearance, and communication protocols to your specification, with CE, IEC, and UN38.3 certifications available for smooth global shipping. Depending on your market and business model, cooperation can range from product supply with your branding to joint product development, and our team, which you can meet at global exhibitions such as SNEC, KEY, and the Canton Fair, supports you from first sample to repeat orders.

Yes. NUUKO offers fully customized PV and energy storage solutions based on project requirements, including system capacity, product configuration, application scenarios, communication requirements, and local market standards. We work closely with customers to design optimized solutions for different energy applications, rather than asking you to fit your project to a standard catalog.

Our customization covers six dimensions: system configuration tailored to project size and energy demand; flexible product portfolio combining PV modules, batteries, inverters, and energy management solutions; capacity and scalability with modular expansion options; functional requirements such as self-consumption optimization, backup power, peak shaving, load shifting, and microgrid operation; adaptable communication interfaces and intelligent monitoring for seamless integration; and compliance with regional regulations, grid requirements, and international certification standards. Tell us your project's conditions and business goals, and our engineering team will turn them into a buildable system design.

NUUKO provides integrated solar PV and battery energy storage solutions for residential, commercial & industrial, utility-scale, and off-grid applications. Our portfolio covers high-efficiency PV modules, residential energy storage systems, C&I and utility-scale battery energy storage systems (BESS), and integrated PV + BESS solutions, all combined with intelligent energy management technologies to meet diverse energy needs worldwide.

Concretely, our solar modules are built on advanced N-type TOPCon and HJT cell technologies, with power outputs ranging from 440W to 725W and module efficiency up to 23.4%; our bifacial double-glass series achieves up to 80% bifaciality for higher energy yield on both sides. On the storage side, we design and assemble complete systems based on safe, long-cycle LFP battery technology. These range from residential batteries starting at 14.3kWh to C&I cabinets at 125kW and above and up to containerized multi-MWh solutions, all with integrated BMS and EMS control and liquid or air cooling options. Whether you need a single product or a complete generation-to-storage system, one partner covers it all.
