From a real need to a production-ready product.
At Shenzhen Lianyang New Energy Technology Co., Ltd, LINKSOLAR product development connects market insight, solar engineering, industrial design, validation and manufacturing preparation.
A solar consumer product has to do more than generate power. It must fit the way someone carries, wears or installs it, protect its electrical system and be practical to manufacture consistently. Our development process keeps those decisions connected from the beginning.
1. Understand the market and the user
Development begins before the first drawing. Our market team and product managers study comparable brands, product formats, prices and user feedback. They collect customer needs, examine competing products and use benchmark comparisons to understand what existing solutions do well and where they create friction.
The result is a product brief that defines the target user, use case, intended specifications, cost target and target selling price. At this point, comparisons help set direction; formal validation comes later.
Participants: Market team and product management.
2. Choose the technical direction
Electronic and structural engineers translate the product brief into an initial system. They determine how the solar module, power electronics, mechanical structure and key user interactions should work together.
This stage locks the main technical route and product framework before detailed engineering begins. Important tradeoffs—available solar area, power requirements, weight, appearance, materials and cost—become visible early enough to address.
Participants: Electronic engineering and structural engineering.
3. Develop the complete design
The concept is developed into engineering drawings, PCB design, 3D structures and production requirements. Industrial designers refine the product’s form and visual direction, while process engineers consider how the parts will be assembled.
These decisions happen together. A clean exterior can affect solar area; a material choice can affect weight and protection; an electronic layout can affect heat, charging behavior and assembly. The product must work as one system.
Participants: Structural engineers, electronic engineers, industrial designers and process engineers.
4. Build engineering prototypes and run EV
Engineering prototypes show whether the proposed design works in practice. Engineering Validation, or EV, focuses on core functions and overall feasibility while the design can still be revised efficiently.
The team reviews the prototype, identifies design problems, tests key functions and turns the findings into the next design iteration.
Main goal: Prove the concept and resolve design-level problems.
Participants: Structural engineering, process engineering, electronic engineering, QA testing and product management.
5. Verify the design through DV
Once the principal design issues are resolved, Design Validation, or DV, checks the product against its approved specification.
The relevant test plan may include electrical performance, environmental exposure, mechanical reliability, protection, service life and applicable safety or compliance requirements. Procurement joins the process so that materials and components are evaluated alongside the design.
Main goal: Verify that the complete design meets its defined requirements.
Participants: Structural engineering, process engineering, electronic engineering, QA testing, product management and procurement.
6. Prepare the production process
A validated design still needs a repeatable way to be built. Engineering trial production is used to review production tooling, fixtures, assembly steps, work instructions and the flow of materials through the line.
The team prepares standard operating procedures and defines how incoming materials, in-process assembly and outgoing products will be checked.
Main goal: Confirm that the production and quality processes can build the design consistently.
Participants: R&D, structural and process engineering, Production and Material Control, production, Incoming Quality Control, Outgoing Quality Control and procurement.
7. Run a small batch, then release production
A small-batch pilot gives the Shenzhen Lianyang team another opportunity to examine assembly consistency, process stability, material coordination and quality results under production conditions.
Only after the product and its production process pass the required reviews does the project move into standard mass production.
The process is a learning loop
Product development is not a straight line in which every decision is made once. Findings from prototypes, validation and pilot production can send the team back to a material, circuit, structure or user interaction for improvement.
After release, questions from customers and observations from the market help inform future revisions and new LINKSOLAR products.
Product-specific evidence still matters
Not every test applies to every product, and test conditions and acceptance criteria belong to the relevant specification. A company-level development process is not a blanket performance claim.
We communicate product-specific output, protection and use conditions on the corresponding product and support pages so customers can evaluate the product they are considering.
