This makes Aide Solar one of the few module producers that have successfully passed the rigorous testing. Passing the PID Test ensures that Aide Solars mono modules can maintain normal output power even when exposed to the harshest environments.
PID, which is commonly seen in large scale system, is the power degradation of module due to exposure to a high negative voltage between cells and ground. The effect could result in power drop at the module level by as much as 50%. The loss of power production has significant impact to the financial interests of project investors? However, manufacturers can prevent such degradation by using PID-resistant cell and module technology.
Using modules that passed PID testing can reduce the technical risk and secure the profit for project investors. The main three components of PID testing are:
1) Under 85?, 85% relative humidity, plus 1000V negative voltage, test for 100 hours;
2) Ambient temperature, plus 1000V negative voltage, test for 168 hours;
3) 60?, 85% absolute humidity, plus 1000V negative voltage, test for 168 hours; PID testing is recognized throughout the PV Industry as the harshest module level test, and only the results from certified testing facilities, such as the TÜV SÜD lab, are recognized as valid.
Aide Solar becomes the first Chinese module manufacturer to complete the 100 hours test level (4 hours more than the test standard). For a module to pass this extreme test, the maximum degradation of power output between initial and final measurement should not exceed 3%. One Aide Solar customer in Europe has documented field data showing a 29.56% higher performance power output than the base performance models. (The base for performance analysis is set with PVSYST V5.4).
