Abstract

PLTS dengan kapasitas, jenis, dan lokasi yang beragam telah dibangun di Indonesia sejak 2011 hingga sekarang, beberapa memiliki kinerja kurang optimal bahkan tidak bertahan lama. Keterbatasan pengelolaan dan penyelesaian masalah PLTS menjadi kendala utama. Beberapa penelitian analisa kinerja PLTS telah dilakukan namun masih bersifat parsial, belum menyeluruh dari seluruh aspek peraltan dan operasional PLTS. Dibutuhkan evaluasi secara menyeluruh melalui penelusuran penyebab akar masalah pada PLTS yang mudah dipahami dan mudah dilakukan secara umum pada berbagai jenis PLTS. Pada penelitian ini dilakukan analisis kinerja PLTS melalui Root Cause Analysis berikut rekomendasi tindak lanjut penyelesaiannya. Hasil penelitian PLTS I (50 kWp, On Grid), PLTS II (100 kWp, Off Grid), dan PLTS III (350 kWp, On Grid) yang lokasinya tersebar pada pulau Sulawesi dan Maluku menunjukkan kinerja PLTS II dan PLTS III belum optimal (Performance Ratio < 60%) sedangkan PLTS I optimal. Hasil agregasi penyebab losses terbesar berasal dari Inverter, Baterai, dan Modul Surya. Hasil Root Cause Analysis menunjukkan losses disebabkan faktor belum memadainya Standing Operational Procedure (SOP) Pengoperasian dan Pemeliharaan, desain dan konstruksi kurang andal, kualitas material rendah, serta kompetensi Operator PLTS kurang memadai. Direkomendasikan prioritas penggantian Modul Surya, Inverter, dan Baterai yang rusak termasuk inovasi pada desain, kualitas material, konstruksi, serta optimalisasi SOP Pengoperasian dan Pemeliharaan, dan juga program pelatihan berkala Operator PLTS. Berdasarkan hasil penelitian, keseluruhan upaya optimalisasi kinerja PLTS melalui pendekatan Root Cause Analysis mudah dipahami dan mudah digunakan secara umum untuk berbagai jenis dan kapasitas PLTS dan lokasi yang berbeda untuk mengoptimalkan rencana tindak lanjut perbaikan secara efektif untuk keberlanjutan operasi PLTS.

Photovoltaic Power Plant (PLTS) with various capacities, types and locations have been built in Indonesia since 2011 until now, some of which have less than optimal performance and even do not last long. The limited management and problem solving of communal PLTS is the main obstacle. Several PLTS performance analysis studies have been conducted but are still partial, not comprehensive from all aspects of PLTS equipment and operations. A thorough search is needed through the root causes of PLTS which are easily accessible and generally carried out on various types of PLTS. In this study, PLTS performance analysis was carried out through Root Cause Analysis and its follow-up to completion. The results of the research of PLTS I (50 kWp, On Grid), PLTS II (100 kWp, Off Grid), and PLTS III (350 kWp, On Grid) located on the islands of Sulawesi and Maluku indicate that the performance of PLTS II and PLTS III is not optimal (Performance Ratio < 60%) while PLTS I is optimal. The results of the aggregation of the biggest causes of losses come from Inverters, Batteries, and Solar Modules. The results of Root Cause Analysis show that these losses are caused by inadequate Standing Operational Procedures (SOP) for Operation and Maintenance, unreliable design and construction, low material quality, and inadequate PLTS operator competence. Recommendations for replacing damaged Solar Modules, Inverters, and Batteries including design innovation, material quality, construction, and SOP optimization, as well as periodic training programs for PLTS Operators. Based on the research results, the overall effort to optimize PLTS performance through the Root Cause Analysis approach is easy to understand and easy to use in general for various types and capacities of PLTS and different locations to optimize follow-up plans for improvements effectively for the sustainability of a PLTS operation.
Keywords: PV Power Plant, Performance, Losses, Root Cause Analysis.
