Abstrak— Penelitian ini merupakan pengembangan dari penelitian terkait dengan perancangan sistem penerangan LED solar simulator. Pada penelitian sebelumnya, solar simulator yang dihasilkan memiliki keterbatasan pada area bidang uji serta tingkat keseragaman yang belum mencapai kelas minimum standar pengujian ineternasional. Tujuan penelitian ini untuk menghasilkan prototipe solar simulator yang mendapatkan karakteristik keseragaman radiasi dan stabilitas temporal pada ara bidang uji 54 x 67 cm serta intesitas cahaya yang dapat dikontrol. Prototipe simulator cahaya menggunakan sumber cahaya LED cool white yang disusun secara hexagon (multi-lamp) yang bisa dioperasikan secara kontinu. Dari hasil pengujian, didapatkan tingkat non-uniformity radiasi sebesar 9,88% (kelas C) dan tingkat instabilitas temporal radiasi dalam penggunaan selama 60 menit sebesar 10% (kelas C) dengan peforma terbaik intensitas target radiasi dari 375 W/m2 sampai radiasi cahaya maksimal 450 W/m2. Berdasarkan dari hasil prototipe tersebut, diharapkan prototipe ini dapat digunakan dalam pengujian modul surya dalam ruangan (laboratorium) dengan target intensitas radiasi yang terkendali.

Abstract— This research is a development of research related to the design of a solar simulator LED lighting system. On research Previously, the resulting solar simulator had limited area field of test and level of uniformity that has not reached the minimum class of international testing standards. The purpose of this research is to produce a prototype solar simulator that obtains radiation uniformity characteristics and temporal stability in the 54 x 67 cm test area and the light intensity that can be controlled. The solar simulator prototype uses a cool LED light source white which are arranged in hexagon (multi-lamp) which can be operated continuously. From the test results, it was found that the level of radiation non-uniformity was 9.88% (class C) and the level of temporal instability of radiation in use for 60 minutes at 10% (class C) with the best performance of the target radiation intensity from 375 W/m2 to a maximum light radiation of 450 W/m2. Based on from the results of the prototype, it is hoped that this prototype can be used in indoor solar module testing (laboratory) with intensity targets controlled radiation.
