DEVELOPMENT AND IMPLEMENTATION OF A MOBILE LABORATORY - PV MOBILE LAB QUALITY ASSURANCE OF PHOTOVOLTAIC MODULES 'ON SITE'

摘要

This paper presents the design, development and results obtained with the mobile laboratory - PV Mobile Lab implemented by Enertis Solar. This laboratory has been designed to carry out the on-site quality control of photovoltaic modules. Such quality control is based on the application of several tests regulated by international standards and presented in previous publications as a plan for quality assurance program QAP. The design of the mobile laboratory ensures the reliability of the results as if conducted in a conventional laboratory. Its innovative design based on an expandable system has allowed for the implementation of a solar simulator tunnel type (illuminated area 2×2m~2 and lamp - DUT distance 5.5 m) in a vehicle that weighs less than 3,500 kg. The spectral, temporal and spatial (non-uniformity) stability of the simulator remain within the parameters of a class A~+A~+A~+ simulator. The environmental conditions during the performance of the tests are controlled and the flash incidence is normal to the module surface. With the development of this powerful tool, Enertis Solar is the first IEC 17025 accredited laboratory capable of performing on-site test in PV modules. The paper shows the first results after 6 months in operation. Furthermore, a detailed example of the results obtained in the quality control of 500 modules tested during the commissioning test of 2 PV plants located in the UK is presented.
