Trina Solar Limited has announced recently that all of its photovoltaic (PV) cells are now integrated with Trina Solar anti-PID or potential-induced degradation ability resulting to greater efficiency. In a statement, the company’s module business unit head Zhiguo Zhu said that the innovation is part of the firm’s commitment to provide its customers with products that have the highest standards of performance. He added that the development is a significant milestone for the company and shows how committed it is in enhancing its manufacturing technology and implementing the highest standards in product quality management.
The company, a leader in the production of PV modules, solutions and services, added that the innovation comes after it optimised its manufacturing technology. It added that all modules utilising its self-produced cells will be consistent with the IEC62804 Ed.1.0 (82/685/NP) standards, also known as the PID test. It also said that it will be able to make modules that will pass stern PID testing criteria.
How do Trina Solar Anti-PID PV cells work?
PID is a procedure that happens in PV cells wherein the system finds a negative potential, decreasing the efficiency of the PV module in the process. While the procedure is quite a new concept, there have been various techniques in place to minimise the undesirable effects like the changes in the system design and materials used.
The Trina Solar anti-PID modules enhance cell and module manufacture technology, resulting to lower power output from solar panels caused by induced degradation. Lower power output could also be caused by other factors like high voltage, high humidity and salt mist which are common in coastal areas.
It remains to be seen how this development of Trina Solar anti-PID will affect the company’s performance this year. The firm had earlier estimated that its solar module shipments were in the range of 540 MW to 570 MW, lower than its previous projections of 670 MW to 700 MW. The lower projections were due to the temporary reduction in shipments to the European Union until an agreement on minimum import price is agreed upon.
Additionally, the company estimates its overall gross margin for the first quarter to be between 18 to 20 per cent.
Trina Solar chairman and CEO Jifan Gao expressed confidence that the market’s demand for its products remains strong and that it will post robust growth this year as projected. He added that he expects the European demand to remain robust and for the company to capitalise on its reputation and customer service in achieving growth in that part of the world.
