The factory is furnished with cutting edge equipment to conduct tests in accordance with UL test standards and procedures. In establishing the facility, JinkoSolar received both technical guidance and oversight from professional technical expert witnesses from UL. In two to three years, JinkoSolar aims to reach a higher level of strategic partnership with UL under its Client Test Data Program (CTDP). Under the CTDP, JinkoSolar will be authorized by UL to conduct test programs independently. “The opening of JinkoSolar’s new world-class PV module testing laboratory complements our mission to produce the highest quality and most reliable solar panels in the industry. The professional personnel and testing facilities will help the Company accelerate its R&D process and reduce lead time of testing and qualification so that we can bring the latest solar technology to our customers as fast as possible.
