Abstract

Degradasi pada photovoltaic menyebabkan penurunan kinerja. Perhatian khusus adanya degradasi pada photovoltaic,yang selama tahun-tahun terakhir dianggap dapat merugikan hasil produksi listrik pada pembangkit-pembangkit yangmenggunakan energi tenaga surya ini, karena berkurangnya daya yang signifikan, yang telah diamati pada sistemphotovoltaic. Laporan ini menganalisa degradasi yang diamati pada sel photovoltaic yang sangat buruk dari modulphotovoltaic 50 WP, photovoltaic 2 busbar cell, dan photovoltaic 3 busbar cell. Pada penelitian ini, mengimplementasikansebuah alat yang digunakan untuk mengetahui degradasi pada photovoltaic dengan metode electroluminescence.Perbandingan nilai efisiensi pada photovoltaic module 50 WP antara yang tidak terdegradasi dengan yang terdegradasisebesar 14,29 % berbanding 7,949 %, perbandingan nilai efisiensi pada photovoltaic 2 busbar cell antara yang tidakterdegradasi dengan yang terdegradasi sebesar 25,669 % berbanding 7,32 %, dan perbandingan nilai efisiensi padaphotovoltaic 3 busbar cell antara yang tidak terdegradasi dengan yang terdegradasi sebesar 21,08 % berbanding 4,95 %.Dari pengujian ini diperoleh nilai selisih efisiensi antara photovoltaic module 50 WP sebesar 6,341 %, photovoltaic 2busbar cell sebesar 14,663 %, dan photovoltaic 3 busbar cell sebesar 16,13 %

Abstract

Electrical capacitance volume tomography (ECVT) is a method for determining the volumetric distribution of dielectric permittivity using the capacitance measurement principle. The determination of volumetric distribution of dielectric permittivity is important to regulate a process in which quantity of materials is a decisive parameter such as in industrial setting or vehicle sub-system. ECVT is a relatively fast and non-radiating method to observe spatio-temporal phenomena inside a process, making it a valuable technique. Sensor modelling and image reconstruction study are essentials in designing a suitable imaging system based on measurements from plurality of electrodes providing higher degree of information being observed. This research conducts sensor modelling with varying fuel objects in the interior of a cylindrical vessel. The capacitance value was simulated between a combination of eight electrodes mounted encapsulating the tube. Each measured electrode was given an excitation voltage as a source of an electrostatic field, which interacts with the object’s presence. The objects in this study are benzene, kerosene, and diesel fuel, along with reference dielectric values of water and air. Image reconstruction used the linear back projection (LBP) method. Matrix operations between sensor’s pre-defined sensitivity and capacitance values produce data that can be plotted into an image estimating the true distribution of objects. Capacitance values from modelling are proportional to the actual object’s permittivity. The reconstruction provides qualitative information on the proportion of fuel in the vessel based on the capacitance value. Images have distinct values according to the presence of different objects under investigation. The research contribution is a proof of concept in using capacitance tomography to detect different fuels inside an enclosed tank at modelling stage. In addition, this study serves as a guideline for implementing a non-invasive and non-intrusive system for determining proportions of materials of interests inside a certain setup.

Abstract

Jenis – jenis kerusakan pada photovoltaic (PV) cells akan menyebabkan penurunan kualitas salah satunya adalah crack pada PV cell. Jenis crack PV cell yang terjadi sangatlah susah untuk dideteksi, kerusakan terjadi didalamnya bahan semikonduktor pada bahan silicon yang terdapat di PV cell dengan tidak bias dilihat pada mata telanjang. Pada penelitian ini bertujuan untuk mendeteksi kerusakan atau cacat dengan menggunakan metode gambar electroluminescence dari PV cells dengan cara catu daya forward bias tengan sesuai dengan spesifikasi pada PV cells dan di capture dengan kamera DSLR dengan modifikasi dengan cara melepas lensa infra red cutfilter pada bagian lensa kamera. Jenis kerusakam pada PV cell terdapat crack pada gambar yang ditangakap kamera dan setelah itu akan dianalisa menggunakan pengolahan citra dengan mengaplikasikan software YOLO v3. Hasil pendeteksian pada gambar dianalisa dan diolah citranya dengan tingkat keakurasian pada sistem adalah 97,30% untuk jenis PV cell normal, 92,22% jenis micro crack, 70,77% jenis several direction crack, dan 93,66% jenis cross crack. Hasil diperoleh aka nada perbandingan output pada photovoltaic cell mendapatkan hasil penurunan tegangan open circuit (Voc) sebesar 9% sampai 18,4%, dan Arus short circuit (Isc) sebesar 23,45% sampai 29,8%.

Abstract

Abstract The research objective is to understand the testing stages of the Indonesian national standardization process on local solar cell products circulating and installed in Indonesia, both imported and local. The solar module is the main component of a solar power plant which has a very important role for its function as a converter of solar energy (the sun) into electrical energy. Solar modules in Indonesia have special standards set by the Indonesian Standardization Agency (BSN). The solar power plant itself is one of the new renewable energy sources (EBT) that produces electricity from the stages of the photovoltaic effect system. Solar power plants can be utilized by people who need electrical energy, but are constrained by the unavailability of electrical energy from PLN, such as people in 3T areas (outermost, underdeveloped, remote) that have not received electricity from PLN.Keywords: Indonesian National Standardization, Solar Module, Solar Cell
