MPrime, a subsidiary of Martifer Solar, has announced its M210-255P series of PV modules has passed the Potential Induced Degradation (PID) test conducted by Photovoltaik-Institut Berlin.
The Photovoltaik-Institut Berlin test measures the sensitivity of the module output parameters when exposed to high system voltages. Modules are considered to show resistance to PID if they lose less than 5% of their nominal power under standardised test conditions.
The test revealed that the MPrime modules had a maximum power degradation of 0.3% even when exposed to 1000V at 85ºC and 85% HR for 96 hours, which is double that of the standard test. This result indicates that the modules are “PID-free”.
Commenting on the result, Pedro Alves, Managing Director of MPrime said: “This is a very pleasing result for us. High resistance to Potential Induced Degradation underlines the high quality of MPrime’s modules and their individual components, ensuring the reliability and long operating life of our products. There are a short number of “PID-Free” modules on the market. It is an important measure for our customers, demonstrating that they can count on the quality of our modules.”
The modules are produced in a factory in Portugal which has been equipped with an advanced production line that is completely automated and robotised. The factory has an annual production capacity of 50MW.
