Germany-based PV module manufacturer SOLARWATT has successfully met the IEC CD 61215-1: Ed.2.0 test for Light and elevated Temperature Induced Degradation (LeTID) for its Vision 60M series PV panels, undertaken by testing and certification house, VDE Renewables.
The IEC CD 61215-1: Ed.2.0 LeTID test includes two temperature cycles of 162 hours each with an applied current to simulate the LeTID phenomenon that can impact PERC (Passivated Emitter Rear Cell) based panels, which causes power degradation.
Under the IEC test, a pass criterion is awarded should the tested panel performance degrade less than 5% after the two cycles. In VDE Renewables' testing of SOLARWATT’s Vision 60M series product, degradation was certified to have been only 1.81%.
Norbert Betzl, director of product management solar panels at SOLARWATT said that “We strive for the best possible assurance of the performance of our solar modules, the predicted efficiency should be maintained in practice. It is essential for us to rule out a deterioration due to the LeTID effect as far as possible."
Leading ‘Solar Module Super League’ supplier, JinkoSolar has teamed with experts from TÜV NORD and Soltec to provide as usual a technically driven PV Tech ‘TechTalk’ series webinar to further understand the Tiger PRO modules impact on LCOE metrics. Register free now.
PV Tech is hosting a TechTalk Product Series webinar with LONGi Solar to help PV project developers, asset owners and interested parties become aware of the latest in utility-scale PV panel technology, performance and size that is redefining LCOE metrics.
Going into its fifth year over 200 delegates from 150 companies and 20 countries representing the PV supply chain will gather in Malaysia to discuss the technology roadmaps for PV cell advancement in GW markets. The scope of the event has been expanded this year, to cover developments in wafer supply and thin-film investments and technologies alongside all the regular benefits to all stakeholders tracking PV technology and investment trends for the next 5 years.
Understand fully the technical and logistical supply chains that determine the production and performance of solar modules, including all related factors impacting quality, reliability & bankability.
