Makalah ini bertujuan untuk mendapatkan performansi produksi energi dari sebuah desain sistem fotovoltaik berkapasitas 1,3 kWp yang terhubung jaringan untuk sebuah bangunan rumah kecil di Bali yang memiliki konsumsi listrik rata-rata 6.36 kWh/hari dengan menggunakan software PVSyst. Lokasi rumah berada pada iklim tropis dengan temperatur rata-rata bulanan sebesar 27,2 ℃ dan rata-rata iradiasi matahari bulanan bervariasi dari 4,41 hingga 7,14 kWh/m 2. Posisi panel fotovoltaik dioptimalkan pada sudut azimuth 0⁰ dan sudut kemiringan 12,5⁰ menghadap ke utara dengan kemiringan tetap tanpa pelacakan. Desain sistem fotovoltaik terdiri dari empat unit modul jenis multi kristal dengan daya puncak per unit sebesar 325 Wp dan tersambung dalam satu larik untuk membentuk pelacakan titik daya maksimum pada inverter. Satu unit inverter dengan daya luaran nominal 1,6 kW digunakan untuk mengubah daya listrik dari arus DC ke AC. Hasil simulasi menunjukkan bahwa iradiasi global dan produksi energi pada luaran inverter bervariasi antara 4,16 dan 6,65 kWh/m 2 /hari dan 129,9-199,7 kWh. Rasio performansi bulanan, faktor kapasitas dan efisiensi sistem berfluktuasi masing-masing antara 76,9-78,6%, 17,3-27,7% dan 12,8-13,0%. Kerugian maksimum array fotovoltaik dan kerugian sistem adalah 1,35 kWh/kWp/hari dan 0,18 kWh/kWp/hari. Hal ini terjadi pada bulan November dimana efisiensi sistem mencapai nilai terendah yang kemungkinan dipengaruhi oleh temperatur lingkungan yang tinggi.

“…Moreover, the thermodynamic model of Brayton heat engine investigated here yields superior values of first law efficiency, output power and ecological function which is true while considering the parametric values of addition heat addition in the current system. The present work can further be extended by applying various evolutionary algorithm techniques [34][35][36][37][38][39][40][41][42][43][44][45][46][47][48] in order to get optimum design of regenerated Brayton heat engine with constant heat addition.…”

The modified configuration of regenerated Brayton heat engine along with supplementary addition of heat in its irreversible mode is thermodynamically investigated and optimized. The definite temperature differential between system/reservoir is the source of external irreversibility and the losses because of rubbing/friction in turbine/compressor, regeneration heat losses and losses due to pressure drop are the internal irreversibilities considered in this analysis. The difference of output power and the exergy destruction rate, termed as ecological function, is thermodynamically optimized. It is found that regenerative effectiveness plays a vital role in obtaining maximum possible ecological function whereas output power and 1 st law efficiency predominantly depends on the cold side effectiveness in the system. It is also observed that the thermodynamic performance of proposed system/device is prominently depends on the efficiency of the turbine and consequently less dependent on compressor efficiency. The major outcome of this analysis is that with the inclusion of additional thermal heats at constant temperature conditions, various performance parameters i.e., output power (about 13%) and 1 st law efficiency (about 9%) of the model get improved significantly in comparison with the conventional gas power plant. Moreover, the model investigated in this study yields lesser output power, first law efficiency and ecological function and exactly follows the results/outcomes presented in the available literature at α1=α2=1, which are the pressure recovery coefficients at two ends.
