Nanosatellites, like CubeSat, have begun completing advanced missions that require high power that can be obtained using deployable solar panels. However, a larger solar array area facing the Sun increases the solar radiation torque on the satellite. In this study, we investigated solar radiation torque characteristics resulting from the increased area of solar panels on board the CubeSats. Three common deployable solar panel configurations that are commercially available were introduced and their reference missions were established for the purpose of comparison. The software algorithms used to simulate a variety of orbit scenarios are described in detail and some concerns are highlighted based on the results obtained. The solar power generation of the respective configurations is provided. The findings are useful for nanosatellite developers in predicting the characteristics of solar radiation torques and solar power generation that will be encountered when using various deployable solar panels, thus helping with the selection of a suitable configuration for their design.

Solar rooftop systems in the residential sector have been rapidly increased in the term of installed capacity. There are various factors, such as climate, temperature, and solar radiation, that have effects on solar power generation efficiency. This paper presents a performance assessment of a solar system installed on the rooftop of residence in different regions of Thailand by using PSIM simulation. Solar rooftop installation comparison in different regions is carried out to evaluate the suitable location. In addition, three types of solar panels are used in research: monocrystalline, polycrystalline, and thin-film. The electrical parameters of real power and energy generated from the systems are investigated and analyzed. Furthermore, the economic evaluation of different solar rooftop system sizes using the monocrystalline module is investigated by using economic indicators of discounted payback period (DPP), net present value (NPV), internal rate of return (IRR), and profitability index (PI). Results show that the central region of Thailand is a suitable place for installing solar rooftop in terms of solar radiation, and the temperature has more solar power generation capacity than the other regions. The monocrystalline and polycrystalline solar panels can generate maximum power close to each other. All solar rooftop sizes with the Feed-in Tariff (FiT) scheme give the same DPP of 6.1 years, IRR of 15%, and PI of 2.57 which are better than the cases without the FiT scheme. However, a large-scale installation of solar rooftop systems can receive more electrical energy produced from the solar rooftop systems. As a result, the larger solar rooftop system sizes can achieve better economic satisfaction.

Indonesia merupakan negara yang memiliki berbagai jenis sumber daya energi dalam jumlah yang cukup melimpah. Wilayah Indonesia akan selalu disinari matahari selama 10 - 12 jam dalam sehari. Data Dirjen Listrik dan Pengembangan Energi pada tahun 1997, kapasitas terpasang listrik tenaga surya di Indonesia mencapai 0,88 MW dari potensi yang tersedia 1,2 x 109 MW. Kebanyakan panel surya dipasang permanen dengan sudut elevasi yang tetap (fixed elevating angles). Hal ini menyebabkan panel surya tersebut tidak dapat menyerap radiasi matahari secara optimal. Penyerapan radiasi matahari akan optimal jika arah radiasi matahari tegak lurus terhadap permukaan bidang panel surya. Penulis tertarik untuk merancang dan membuat alat yang dapat dipergunakan untuk menempelkan panel sel surya tetap dalam kondisi intensitas matahari yang maksimum. Dalam hal ini, menggunakan satu sumbu. dengan telah dibuatnya alat penggerak mekanik satu sumbu pada solar panel ini, penulis dapat memberikan gambaran tentang pembangkit listrik tenaga surya kepada masyarakat. Selain itu dengan adanya penggerak mekanik pada solar panel ini, solar panel bisa lebih besar menghasilkan tegangan pada baterai daripada solar panel tanpa penggerak. Dan dari percobaan menggunakan penggerak mekanik satu sumbu ini menghasilkan tegangan di pukul 08.00 pada baterai nominal sebesar 2,04V hari pertama, 2,05V hari kedua dan 2,03V hari ketiga dan di akhir perhitungan pukul 16.00 tegangan pada baterai menujukan nominal sebesar 11,18V hari pertama, 11,27V hari kedua dan 11,3V hari ketiga.Kata Kunci : Solar Panel, Tipe BCT30-12, Penggerak Satu Sumbu Indonesia is a country that has different kinds of energy resources in sufficient quantities abundant. then Indonesia will be always exposed to the sun for 10-12 hours a day. Data Director General of Electricity and Energy Development in 1997, the installed capacity of solar power in Indonesia reached 0.88 MW of the available potential of 1.2 x 109 MW. Most solar panels are installed permanently at a fixed elevation angle (fixed elevating angles). This causes the solar panels can not absorb solar radiation optimally. Absorption of solar radiation would be optimal if the solar radiation direction perpendicular to the surface of solar panel field. Writers interested in designing and creating tools that can be used to attach the solar panels remain in a state of maximum intensity of the sun. In this case, using a single axis. to have made a mechanical actuator on the solar panel one axis, the author can give an idea of solar power plants to the public. In addition to the mechanical drive on the solar panels, the solar panels generate voltage can be larger than the solar panel to the battery without driving. And from experiments using mechanical drive one axis produces a voltage at 08.00 at a total nominal battery 2,04V first day, 2,05V 2,03V second day and third day and at the end of the calculation 16.00 nominal voltage of the battery addressed by 11,18V the first day, 11,27V 11,3V second day and third day.keyword : Solar Panel, Type BCT30-12, Activator One Wick

This paper studies the effect of temperature, humidity and irradiance on the power generated by a photovoltaic solar cell. This was achieved using pyranometer for determining the solar radiation, wet and dry thermometer for measuring humidity, and digital multimeter for voltage and current measurement. The result of the study show that power generation increases with increase of solar irradiance. Additionally, changes of humidity level and temperature do not significantly affect solar power generation. Furthermore, it was also observed that high temperatures and higher humidity levels accelerate the corrosion process on the solar cells which reduces the efficiency of the cells.

An agrivoltaic system is a combination of solar power generation and crop production that has the potential to increase the value of land. The system was carried out at a 25-kW photovoltaic (PV) power plant located at the Asian Development College for Community Economy and Technology (adiCET), Chiang Mai Rajabhat University, Thailand. The growth and yield of bok choy (Brassica rapa subsp. chinensis L.) and the solar power output were investigated and compared with the control. Moreover, the efficiency of the agrivoltaic system was evaluated. The results indicated that the average intensity of solar radiation of 569 W/m2 was obtained. The highest power generation was recorded in the PV with crop production of 2.28 kW. Furthermore, the control plot of crop production at 35 days provided higher growth than bok choy plots under solar panels of 2.1 cm in plant height, 6 in leaf number, 2.2 cm in leaf length and 0.2 cm in leaf wide. High-yield of bok choy was also obtained in the control plot of 17.31 kg. Although the yield of bok choy is extremely low, possibly because of light intensity, crop cultivation under solar panels could reduce the module temperature to less than the PV control of 0.18 °C, resulting in increased voltage and power generation by around 0.09 %. Therefore, an agrivoltaic system is another option for increasing revenue and land equivalent ratio in solar power plants focusing only on electricity generation. However, suitable crops for the space under PV panels should be investigated further.

Background/Objectives: In designing the solar power generation, feasibility review and power generation volume prediction during guarantee phase after the completion are very important.Methods/Statistical analysis: The study compares the actual power generation volume obtained from solar power generation monitoring system and estimated volume calculated using overseas meteorological data from Meteonorm 7.1 and NASA-SSE and Korean data from the Korea Meteorological Administration, in order to understand their accuracy. The calculation using KMA data, with the highest prediction value, was used to analyze the correlation among solar radiation, temperature, and solar power generation volume.Findings: Previous solar power generation volume prediction was conducted only with solar radiation value, which caused errors between the actual and predicted solar power generation volume. The study found that the power generation volume and solar radiation have a high positive correlation coefficient of 0.8131 for Songam Power Plant. For correlation between power generation volume and temperature, the coefficient for Songam was 0.2843 and 0.4616 for Jipyeong Power Plant, showing lower influence than that of solar radiation. In sum, solar radiation influences the solar power generation volume more than temperature, but the current study indicates that both solar radiation and temperature must be considered for an accurate prediction of solar power generation volume.Improvements/Applications: Research to develop solar power generation volume prediction algorithm that takes into account both solar radiation and temperature must be conducted to expand the application of solar power generation system with more accurate estimation of power generation volume.
