Abstract

With the increase in the use of solar energy, the investigation of the failures that cause the decrease in efficiency and loss in production is increasing day by day. It is extremely beneficial to conduct on-site testing of solar systems in order to evaluate the plant's actual performance and identify potential problems. There are important methods for on-site and fast detection of failures. In this study, the failures in the panels were analyzed using the Electroluminescence test, which is one of the most reliable methods for the detection of micro-cracks, and 11 failures were detected as a result of the EL imaging. The EL test, which is the most reliable method for detecting micro-cracks, has been compared with infrared thermal images and its superiority has been proven. Energy losses were prevented by intervening in the field with rapid fault detection.

Özet

Güneş enerjisi kullanımının artması ile birlikte verimin düşmesine ve üretimde kayıplara sebep olan arızaların araştırılması gün geçtikçe artmaktadır. Tesisin gerçek performansını değerlendirmek ve potansiyel sorunları belirlemek için güneş enerjisi sistemlerinin yerinde test edilmesi son derece faydalıdır. Arızaların yerinde ve hızlı tespiti için önemli yöntemler mevcuttur. Bu çalışmada mikro çatlak tespiti için en güvenilir yöntemlerden biri olan Elektrolüminesans test kullanılarak panellerdeki arızalar analiz edilmiş ve EL görüntüleme sonucunda 11 arıza tespit edilmiştir. Mikro çatlakları tespit etmede en güvenilir yöntem olan EL testi kızılötesi termal görüntüler ile karşılaştırılmış ve üstünlüğü kanıtlanmıştır. Hızlı arıza tespiti ile sahada müdahale edilerek enerji kayıplarının önüne geçilmiştir.
