Quality, reliability, and durability are the key features of photovoltaic (PV) solar system design, production, and operation. They are considered when manufacturing every cell and designing the entire system. Achieving these key features ensures that the PV solar system performs satisfactorily and offers years of trouble-free operation, even in adverse conditions. In each cell, the quality of the raw material should meet the quality standards. The fulfillment of the quality management system requires every part that goes into the PV solar system to undergo extensive testing in laboratories and environments to ensure it meets expectations. Hence, every MWh of electricity generated by the PV solar system is counted, the losses should be examined, and the PV system’s returns should be maximized. There are many types of losses in the PV solar system; these losses are identified and quantified based on knowledge and experience. They can be classified into two major blocks: optical and electrical losses. The optical losses include, but are not limited to, partial shading losses, far shading losses, near shading losses, incident angle modifier (IAM) losses, soiling losses, potential induced degradation (PID) losses, temperature losses, light-induced degradation (LID) losses, PV yearly degradation losses, array mismatch losses, and module quality losses. In addition, there are cable losses inside the PV solar power system, inverter losses, transformer losses, and transmission line losses. Thus, this work reviews the losses in the PV solar system in general and the 103 MWp grid-tied Al Quweira PV power plant/Aqaba, mainly using PVsyst software. The annual performance ratio (PR) is 79.5%, and the efficiency (η) under standard test conditions (STC) is 16.49%. The normalized production is 4.64 kWh/kWp/day, the array loss is 1.69 kWh/kWp/day, and the system loss is 0.18 kWh/kWp/day. Understanding factors that impact the PV system production losses is the key to obtaining an accurate production estimation. It enhances the annual energy and yield generated from the power plant. This review benefits investors, energy professionals, manufacturers, installers, and project developers by allowing them to maximize energy generation from PV solar systems and increase the number of solar irradiation incidents on PV modules.

“…Hanya saja cara tersebut kurang akurat untuk memodelkan efek pembayangan, dikarenakan posisi modul PV yang kurang akurat. Dalam memodelkan efek pembayang, pergeseran sedikit dari posisi PV modul membuat perubahan yang besar dari energi yang dihasilkan [20].…”

Pada penelitian ini, berkontribusi untuk mencari sudut, lokasi, dan susunan modul PV kanopi optimum dengan metode analisis pembayangan menggunakan simulasi perangkat lunak PVSyst. Kapasitas modul PV yang digunakan sebesar 20 kWp yang diintegrasikan sebagai kanopi di jalan penyeberangan LABTEK V dan LABTEK VI kampus ITB, Bandung. Koordinat dari lokasi modul PV yang digunakan yaitu 6,89 LS dan 107,61 LT (- 6,89 oS, 107,61 oE). Tipe pemasangan PV yang digunakan yaitu tipe kemiringan tetap atau fixed tilt. Objek bangunan dan pohon di sekitar modul PV menyebabkan efek pembayangan di modul PV dan perlu dilakukan optimasi dan analisis pembayangan untuk menghasilkan kinerja maksimum. Optimasi pertama dilakukan yaitu optimasi sudut dengan mencari sudut kemiringan dan azimuth optimum untuk menghasilkan kinerja yang maksimum. Hasil yang didapat yaitu kinerja maksimum terjadi pada sudut kemiringan PV 11o dan azimuth 0o dengan iradiansi global efektif sebesar 1160,1 kWh/m2/tahun dan energi susunan PV sebesar 21,75 MWh/tahun. Setelah dilakukan optimasi sudut, dilakukan penambahan skenario optimasi yaitu optimasi pergeseran dan susunan PV untuk meningkatkan kinerja modul PV. Pada penambahan skenario optimasi pergeseran dan susunan, terjadi peningkatan iradiansi global efektif yaitu berturut-turut sebesar 72 kWh/m2/tahun dan 14,9 kWh/m2/tahun dan peningkatan energi susunan PV yaitu berturut-turut sebesar 1,26 MWh/tahun dan 0,25 MWh/tahun. Kata Kunci— PV kanopi, iradiansi global efektif, energi susunan modul PV, analisis pembayangan

As an example of green energy (geothermal energy), which has been the subject of advanced research in recent decades, the earth-to-air heat exchanger (EAHE) is the application of an air heat exchanger to soil temperatures, in which air circulates in tubes in thermal contact with the ground. The performance of the EAHE cooling system is evaluated at two separate sites (arid and semi-arid) in Algeria throughout this investigation. The impact of the EAHE system's entombed depth is then considered in this paper. According to our earlier research, the proper depth of the inhumed pipes is set at 3 m. The thermo-physical properties of the soil at several sites located in southern Algeria (Ghardaia: 32° 22′ 54′′ North, 3° 47′ 58′′ East) and Ouargla: 31° 55′ 53′′ North, 5° 24′ 24′′ East) are implemented by writing a program with the Scilab 6.0.2 software. Based on the results obtained, it can be concluded that the thermal range parameter is a more relevant and efficient parameter for evaluating the thermal performance of the EAHE (Earth-to-Air Heat Exchanger) system. Furthermore, the Ouargla region is a suitable location for the experimental realization of the EAHE system. The thermal amplitude interval (Trange) in Ouargla during the annual period is larger compared to Ghardaï a, with maximum values of 22.5℃ and 20℃ respectively. It is worth noting that the thermal comfort level (20-27℃) is more suitable for the Ouargla region rather than Ghardaï a. Additionally, there is an average difference of around 2.5℃ in the thermal amplitude between the two zones during the hot season, further highlighting the superiority of the Ouargla region.
