Discover how every DER solar street light is manufactured—from raw materials and precision machining to assembly, testing, packaging, and global shipment.
DER focuses on All-in-One Solar Street Lights instead of offering scattered lighting products. This allows us to improve product design, configuration, manufacturing, and market support around one clear category, helping customers build a more professional and focused product line.
DER works with distributors, importers, wholesalers, and private brands that need products they can sell in their local markets. From product selection to OEM branding and sales materials, we help customers choose products that are easier to introduce, promote, and sell.
Different customers need different cooperation models. DER supports finished products, OEM products, ODM development, SKD kits, housing and component supply, contract manufacturing, and production setup support, giving customers more flexibility to build their own solar lighting business.
DER helps customers create their own branded product lines with logo printing, labels, packaging, manuals, catalogs, and sales materials. We can also support product modification, market-based configuration, and exclusive product development for customers with specific requirements.
Every order is supported by controlled production, component checks, functional testing, appearance inspection, packaging review, and pre-shipment inspection. Our goal is to help customers reduce quality risks, improve consistency, and avoid unnecessary after-sales problems.
DER support does not stop after delivery. We continue to assist customers with product documents, installation guidance, troubleshooting, spare parts, warranty coordination, and marketing materials, helping distributors serve their customers more professionally and build repeat business.
We do not only ship products. DER provides the documents, visual materials, branding support, technical information, and after-sales assistance distributors need to promote All-in-One Solar Street Lights more professionally in their local markets.

DER supports troubleshooting, spare parts, warranty claims, installation questions, and technical communication after delivery, helping you serve your customers with more confidence.
Before a single light leaves our 20,000 m² factory it passes through five mandatory checkpoints — each independently logged and traceable to a batch number. This is the proof layer behind every claim we make about reliability.
01
Every incoming batch—including solar panels, LiFePO₄ cells, LED chips, controllers, and aluminium components—is inspected against approved specifications before entering production, ensuring only qualified materials move forward.
02
Quality checkpoints are built into every production stage, from machining and powder coating to SMT assembly and final integration, ensuring consistent workmanship throughout manufacturing.
03
Every finished product undergoes functional verification, charging and discharging tests, lighting performance checks, and aging tests to ensure stable operation before shipment.
04
Products are independently tested and certified to international standards, including ISO 9001, CE, RoHS, IP, IEC, and other market-specific compliance requirements.
05
Each shipment is subject to a comprehensive final inspection covering appearance, functionality, packaging, and labeling. Every product is traceable through standardized production and quality records.
