Our factories combine decades of manufacturing know-how with modern automation. Key production stages — cell sorting and pre-stringing, automated soldering/stringing, lamination in vacuum/heat presses, frame assembly and junction-box integration — run on controlled, automated lines to reduce human error and improve repeatability. Inline sensors and PLC controls monitor temperature, pressure and cure profiles during lamination, ensuring consistent electrical and mechanical performance from panel to panel.

Quality is verified at multiple checkpoints. Incoming materials are sampled and certified; during production every panel is inspected with electroluminescence (EL) imaging to reveal micro-cracks and hidden defects, then flashed to record IV curves and power output. Finished units undergo insulation and leakage tests, thermal cycling, mechanical load and PID-resistance screening as appropriate. We combine automated inline inspection with human spot checks and maintain full traceability — serial numbers and batch records allow root-cause analysis and a fully auditable quality trail.

Safe delivery begins before the pallet leaves the factory. We design packaging to absorb shock and moisture: protective corner guards, moisture-barrier bags, pallet stabilization, and custom internal supports for framed modules. Packages are validated with drop, vibration and compression testing to industry standards so customers receive panels intact. Logistics packaging is matched to the route and handling — export crates and palletized loads are prepared to minimize damage through transit.

JJN Solar is built on a simple mission: provide affordable, durable solar that helps people and the planet. From sourcing recyclable materials where possible to optimizing module lifetime performance, we design products that reduce customers’ carbon footprint and total cost of ownership. Buying JJN means joining a practical, long-term push toward cleaner energy — we stand behind our modules with clear warranties, serviceability, and a commitment to continuous improvement for a greener future.
