It is essential for PARU to maintain the highest quality standards for its products and services. The company is certified for the design of its trackers, as well as for the engineering, installation, operation and maintenance of ground-mounted solar plants.
CE Certificate-Efficiency(European Union)
In 2014 Black & Veatch evaluated PARU and proved the qualification and requirements. This criteria could include certification, years in business, proven quality and client approach. Other factors include value-added products and services, record of on-time performance, and health and safety performance.
PARU Team & Facility
PARU uses its own technology and facility to manufacture the best quality products. In Sunchon, the headquarters facility has the sensor and controller assembly lines and in Yulchon, the 2nd factory has the key component, welding, and assembly lines. Seoul office is in charge of domestic and international sales and marketing. PARU also has abroad corporate bodies that continue international solar projects.
1. Critical parts assembly & function test
The critical parts (Slew drive, Actuator, Sensor, Controller) components are assembled into the parts in the an assembly line. Once the components have been assembled, the critical parts must pass a function test. 100 percent of the critical parts assemblies are put through the functional test, and the results are recorded in a log.
2. Laser cutting & Bending
When the materials arrive from the suppliers, they are laser cut, bend and press into the desires shape, followed by visual inspections. Dimensional measurements are performed by hand with calibrated tools and compared with original drawings.
3. Manual & Robot welding
Paru has a welding jig set to ensure that pieces are welded in the correct place and alignment. The jig set includes one jig for the top post and one for he bottom post.
4. Material warehousing & Incoming Inspection
The incoming steel materials are placed in Paru’s warehouse. PARU performs visual incoming inspections on the structural steel parts . The supplier will perform functional tests prior to product delivery and provide a certificate to Paru, and Paru will also perform 100% functional inspection before further processing.
5. Process inspection
Another visual inspection and a magnetic particle inspection will be performed after welding, the inspection sampling rate is one percent according to Paru’s internal instructions. If any defects are found in the inspections, the products will be sent back to rework.
The welded parts will be sent out for galvanization at third parties. The galvanization contractor performs 100 percent inspections on appearance and bending/deformation test, and provides certificates of compliance with the delivered product.
7. Packing & Shipment
The last procedure of the manufacturing is the packing. After packing, the products will be delivered directly to the project sites. The products will be delivered to Kwangyang port in trucks for shipment to Long Beach port. In the US, the products are shipped by train and truck, as scheduled by the overseas business department in Paru’s Seoul office. The Seoul office also coordinates Paru and the other suppliers to meet the shipping schedule.
