The PV Module Testing (PVMT) Laboratory started its operations in 2010 to serve the solar industry in the certification and testing of PV modules, components and accessories. Located in CleanTech Park, we have regularly embarked on equipment upgrades and system updates to remain relevant to the changing needs of the solar industry. Our research testing activities such as fast NMOT or PID recovery allow us to address specific concerns of our customers. The PVMT laboratory is ISO/IEC 17025 accredited by the Singapore Accreditation Council (SAC). In 2018 we have been active to obtain the accreditation encompassing the entire lab reliability and safety testing services, and to get the IEC 61215, IEC 61730 and UL 1703 standards included in the scope of the accreditation.
Defect and root cause detection are increasingly required as more and more PV systems are deployed in the field. Our timely and professional reporting of the fault(s) helps the stakeholders of PV systems to gather more information, address any performance degradation of their assets, and quickly establish the restoration of optimal solar power generation for lowest levelised cost of energy (LCOE).
We have resources that enable the electrical, mechanical, optical and spectral analysis of all commercially available PV modules. This enables us to detect and locate a range of faults, and recommend corrective actions for the PV industry.
Our specifically designed rating methodology - the SERIS Quality Check (SQC) - allows us to monitor and characterise modules that have been shortlisted for deployment in the field before, during and after installation. Modules are periodically checked and monitored for their optimal operation. Recently, a special case of light induced degradation occurring at elevated temperature and irradiance conditions has received great attention in the PV community. This effect might also occur in the tropics. We are now able to offer tests and monitoring of the Light and elevated Temperature Induced Degradation (LeTID) phenomenon and studies of its recovery.
SERIS operates as Testing Laboratory of the Certification partners VDE and TUV SUD .
The PVMT Laboratory is equipped to test in accordance to the PV module qualification standards IEC 61215, IEC 61730 and UL 1703. With our comprehensive tests and skilled team of engineers and scientists, we are well positioned to serve the PV industry in a timely and efficient manner.
Equipped with two large-area pulsed solar simulators, a Pasan SunSim 3B and a long-pulse h.a.l.m. tester, we can characterise almost all types of modules, in particular large-size c-Si and CdTe modules, at Standard Test Conditions (STC). This is particularly important for module manufacturers who need a set of “Golden Modules” to calibrate the solar simulators on their production lines. Both simulators are equipped with a thermal chamber, allowing measurements at any module temperature in the range of 15 to 75 °C. Our flexible mounting structure allows us to measure modules with an area of up to 2.4 m × 1.8 m, depending on the customer needs. We are ready for next-generation PV modules with larger sizes and novel technologies, including bifacial PV modules.
