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.

NUUKO solutions are designed for a wide range of applications: residential solar + storage systems, commercial and industrial energy storage (C&I BESS), utility-scale battery energy storage, off-grid solar solutions, microgrid energy systems, and renewable energy integration projects. From a family rooftop to a national-scale power plant, the same engineering discipline applies at every scale.

These are not theoretical scenarios; they are projects we have delivered. Our reference list includes residential installations from Sweden and Australia to England and Poland, commercial and industrial projects in Italy, Thailand, and Shenzhen, and large ground-mounted plants such as 45MW in Saudi Arabia and 10MW in Mexico, alongside off-grid supply in Yemen. Each scenario has different priorities: self-consumption for homes, demand charge reduction for factories, and grid support for utilities. Our solution design starts from those priorities rather than from a fixed product template.

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.
