Panel surya semakin banyak digunakan untuk berbagai tujuan, bukan hanya untuk pencahayaan rumah. Panel surya atau sel surya sekarang juga digunakan sebagai tenaga penggerak air untuk pengairan. Penggunaan panel surya yang semakin masif merupakan sebuah peluang yang besar terutama bagi generasi muda. Fenomena saat ini menunjukkan bahwa kurangnya tenaga kerja dalam pemasangan instalasi panel surya sedangkan permintaan pasar untuk tenaga pemasang panel surya semakin tinggi. Sungguh menguntungkan jika masyarakat dapat dididik tentang cara memasang sistem listrik tenaga surya. Studi lapangan awal menunjukkan bahwa penggunaan panel surya sangat menguntungkan karena membantu rumah hunian mengurangi biaya listrik bulanan yang harus dibayarkan ke PT PLN (Persero). Pada saat ini, sebagian besar panel surya tidak dapat berfungsi karena beberapa komponen rusak, seperti panel surya, fitting, dan aki. Masyarakat tidak memahami sistem dan cara memperbaikinya, sehingga panel surya tidak berfungsi dan pada akhirnya didiamkan begitu saja. Orang-orang akhirnya memilih kembali menggunakan listrik dari jaringan PT. PLN (Persero). pengabdian ini bertujuan melatih para generasi muda yang dimulai dari siswa-siswa sekolah menengah kejuaruan (SMK). Untuk menyelesaikan permasalahan tersebut, dilakukan praktek pemasangan komponen system panel surya seperti: install panel surya, memilih inverter dan memasangnya serta merangkai rangkaian pengontrol cas baterai. Kegiatan Pengabdian Masyarakat berupa pemasangan dan pelatihan PLTS telah berjalan sukses. Peserta pelatihan menunjukkan antusiasme yang tinggi dalam mengikuti seluruh tahapan pelatihan, mulai dari teori hingga praktik langsung. Hasil pelatihan menunjukkan peningkatan pemahaman peserta mengenai pemasangan dan pemeliharaan PLTS.

Significant advancements in Light-Emitting Diode (LED) technologies, including the availability of high-power LEDs at reduced costs, have rendered them a highly desirable and dependable solar simulator. However, there are still challenges in designing LEDs as solar simulators to evaluate the characteristics of specific solar modules across different technologies and sizes, particularly regarding spectral composition and spatial uniformity of irradiation. This work seeks to develop a prototype LED solar simulator capable of generating uniform light with stability of at least 90% (class C) throughout an illumination area of 54 cm × 67cm for laboratory instructional applications. The employed procedures encompass the selection of high-power LED bulbs, thermal management, electrical design, prototype fabrication, and performance assessment. The International Electrotechnical Commission (IEC) 60904-9:20 standard delineates the performance criteria for solar simulators and serves as a framework for constructing LED solar simulators. The study's results demonstrate that the LED solar simulator prototype has been successfully constructed and is categorized as class C, exhibiting a light non-uniformity and stability level of 10%. The capacity to delineate the current and voltage of a 50 cm × 30 cm small solar module under specified irradiance and temperature circumstances may be attained with a mean absolute error percentage of 0.01 and a root mean square error of 0.21. The hexagonal configuration of the LED array offers advantages for light design, including modularity and ease of expansion to achieve a broader illumination area. This arrangement can serve as an invaluable instrument to enhance solar energy research and maximize the performance of photovoltaic devices under regulated conditions.

The research aims to get the best slope of the solar module to be placed on the roof of the building. This research will look at the performance of solar panels with varying slopes from various types in the city of Banda Aceh. The method used in this research is data collection by looking at the most significant output power from various slopes and comparing it with calculating the output power. The data from each month will also be compared so that the cross panel and the best tilt angle will be. From the research that has been done, it is found that in December and January, with the sun's declination angle of 23 ° and 20 ° North Latitude, the orientation of the solar panel installation is facing south with the best tilt angle of the solar panel is 20 ° -25 ° in December and 18 ° -24 ° in January. In July, the sun's declination is 21.2 ° North Latitude. The orientation of the solar panel installation is facing North, with the best tilt angle of the solar panel being 15 °.

This research focuses on analyzing power losses due to load imbalance in the medium-voltage distribution network in Pasar Aceh. The aim is to determine the magnitude of power losses that occur at the distribution substation in Pasar Aceh. The research method involves analysis, calculations, and simulations using the ETAP 12.6 software. The results of the analysis indicate that load imbalance in the Pasar Aceh substation leads to power losses. The Trafo Samping Pasar Aceh experiences power losses of 0.77% with a load imbalance of 16.33%. The second transformer in the BNI 46 area incurs power losses of 0.98% with a load imbalance of 30.33%, and the transformer in the BLKG KOTTY area has power losses of 1.17% with a load imbalance of 50.33%. These findings affirm that the greater the load imbalance, the higher the resulting power losses in the electrical distribution network.

A mismatch in the output power of photovoltaic (PV) modules in a PV array can occur due to partial shading or a module replacement. Substitution of a module in a PV array with a new one might lead to different current and voltage characteristics between the new and existing modules and result in power losses. The amount of power loss might be increased more if the PV array experiences partial shading. For this reason, this study aims to investigate the effect of partial shadings on the power output of photovoltaic arrays with different current and voltage characteristics. The PV array under test consists of 25 units of solar modules with a total cross-tied (TCT) configuration. There are five shading conditions applied to the test PV array, i.e., the short narrow (ShN), the short wide (ShW), the long narrow (LnN), the long wide (LnW), and the diagonal. A magic square method is applied to reduce the power loss when the PV modules experience partial shading conditions. The results show that the power loss due to partial shadings, either on all identical modules or partially identical, is the same. The most significant power loss occurs in the long comprehensive shading scenario, where 80% of the modules experience shading, which is 41.30%.
