There is no denial that renewable energy is considered to be the most cost-competitive source of clean power in many parts of the world. Saudi Arabia’s vision 2030 aims at achieving the best by using different sources of renewable energy such as solar energy, wind energy, and others. The use of solar energy in particular for power generation will decrease the dependency on oil, and thus, decrease the greenhouse gasses. Solar panels efficiency tends to decrease with the accumulation of dust on their surface. Thus, a cleaning process requires assigning and employing labor, which increases the cost of running as well as high cost of machinery. The current study focuses on assessing and designing a simple auto self-cleaning system in order to improve the efficiency of the solar panel. The results showed that for the Al-Khobar region, Eastern Province, Kingdom of Saudi Arabia, the efficiency of the solar panels after cleaning was increased from 6% to an average of 12% at nominal temperature of 27 °C. In addition, the average power output was increased by 35% during the day time. In addition, the normal efficiency of the solar panels before cooling was between 10% to 15% at 42 °C. After cooling, the temperature of solar cells decreased to 20 °C and the efficiency increased by 7%. Moreover, the output power was increased by 31% with maximum efficiency of 32% at noon time.

Looking at the history of solar energy and renewable energy in general, the authorities and scientists have been paying much attention to the recent period, due to the depletion of fossil energy resources and the growing difficulties in solving environmental problems. The development of solar energy has led to the use of solar energy concentrators. Concentrators are used to concentrate sunlight onto PV cells. This allows for a reduction in the cell area required for producing a given amount of power. The goal is to significantly reduce the cost of electricity generated by replacing expensive PV converter area with less expensive optical material. In this chapter, the authors talk about concentrators in solar energy, especially about modules based on holographic films. Holographic solar panels (HSP) in recent decades have appeared in large-scale production and been actively used in solar energy. Evaluations of other types of existing concentrators are presented.

This research aimed to build a solar tracker for a floating solar panel and used long–range (LoRa) communication to harvest energy and monitor its process. With the rising demand for renewable energy in these recent years especially for solar energy, it needs to meet this demand to remain relevant for the upcoming years where it will have an even larger impact as we shift into clean energy. Monitoring single–axis solar trackers on rural areas difficult and cost–intensive. The purpose of a floating solar farm is to reduce the cost from buying/renting land. Floating solar panels cannot be monitored using wired because they are moving nodes in the water, it makes wired installation complicated. Hence, using wireless sensornetwork is a solution that allowsremote monitoring of floating solar panels in rural areas and makes moving nodes mentioned above possible. Testing wasperformed by sending 100 packets from the node to its gateway using LoRa modulation, and the gateway successfully received about 90% of the packets sent by the node. The vertical single-axis solar tracker used in floating solar managed to get 17% more energy than the fixed solar with a more stable income for the whole duration of sending 100 packets.©2020.

Terbatasnya energi fosil di Indonesia menyebabkan adanya pengembangan energi baru terbarukan. Energi terbarukan merupakan energi non-fosil yang berasal dari alam. Pemanfaatan energi surya bisa dilakukan dengan membangun Pembangkit Listrik Tenaga Surya (PLTS). Perencanaan PLTS menggunakan sistem on grid, sistem masih terkoneksi dengan jaringan PLN. Sistem dimanfaatkan sebagai backup untuk aliran listrik. Sistem akan bekerja secara otomatis ketika aliran listrik PLN terputus dengan memanfaatkan panel ATS (Automatic Transfer Switch). Pembangkit listrik tenaga surya sistem on grid ini cocok diterapkan di perumahan dengan memanfaatkan atap sebagai ruang untuk menyerap energi matahari. Sistem ini jika dipasang bersamaan dengan PLN akan mengurangi pengeluaran biaya listrik. Penerapan sistem atau prinsip kerja PLTS Grid Tie System ini dapat dijalankan dengan sistem kelistrikan PLN. Dalam sistem ini, jaringan listrik PLN berperan sebagai penyalur atau penghubung arus listrik yang berasal dari panel surya yang dialirkan pada beban. Dengan begitu pada siang hari, penggunaan listrik dapat memanfaatkan energi listrik dari sinar matahar dan pada malam hari karena tidak ada sinar matahari menyebabkan tidak ada produksi listrik dari solar panel, maka dapat tetap menggunakan arus listrik yang berasal dari PLN. Perencanaan dilakukan dengan pemilihan komponen PLTS, beban yang dibutuhkan 900Watt, lama waktu penyinaran efektif 10 jam/hari. kemudian melakukan perhitungan komponen PLTS, menentukan tata letak penempatan panel surya dan panel ATS (Automatic Transfer Switch) yang digunakan untuk membackup apabila jaringan listrik PLN terputus. Dari hasil pengukuran arus, tegangan dan daya di dalam rumah pada jam 07.00 sampai dengan 17.00 pada waktu cuaca cerah, yaitu sebelum Grid Tie Inverter dihubungkan ke jala-jala dihasilkan daya rata-rata, P=606,105Watt dan setelah Grid Tie dihubungkan ke jala-jala, P=292,63 Watt. Jadi penghematan daya beban di rumah yang dihasilkan sebesar 52 % dalam satu hari. Limited fossil energy in Indonesia has led to the development of new and renewable energy. Renewable energy is non-fossil energy that comes from nature. Utilization of solar energy can be done by building a Solar Power Plant (PLTS). PLTS planning uses an on-grid system, the system is still connected to the PLN network. The system is used as a backup for electricity. The system will work automatically when the flow of PLN electricity is cut off by utilizing an ATS (Automatic Transfer Switch) panel. This on-grid solar power plant system is suitable for residential use by utilizing the roof as a space to absorb solar energy. This system if installed together with PLN will reduce expenditure of electricity costs. The application of the system or the working principle of the PLTS Grid Tie System can be run with the PLN electrical system. In this system, the PLN electricity network acts as a distributor or connector for the electricity that comes from the solar panels that are flowed to the load. That way during the day, the use of electricity can take advantage of electrical energy from the sun and at night because there is no sunlight it causes no electricity production from solar panels, it can still use the electric current that comes from PLN. Planning is done by selecting the PLTS component, the load required is 900 Watt, the duration of effective irradiation is 10 hours / day. Then calculate the PLTS components, determine the layout of the placement of the solar panels and ATS (Automatic Transfer Switch) panels which are used to back up when the PLN electricity network is interrupted. From the results of measuring currents, voltages and power in the house at 07.00 to 17.00 when the weather is clear, that is, before the Grid Tie Inverter is connected to the grid, the average power is generated, P = 606.105Watt and after the Grid Tie is connected to the grid mesh, P = 292.63 Watts. So, the resulting load power savings at home is 52% in one day

The use of renewable energy as a source of electrical energyincreases every year. Unfortunately, Indonesia does not have manypower plants that utilize renewable energy sources. The mostpotential renewable energy in Indonesia is the sunlight with the helpof solar panels that converts solar energy into electrical energy.However, the environment could affect the solar panel module andin turn, affect the performance of solar panels or the generatedelectric energy. This research calculated the performance of solarpanels with a single-diode model using the Five Parameters methodthat required solar panel module specification data, the totalradiation absorbed by the solar panel module, and the temperatureof the environment. The Five Parameters method is a methodmodeled after solar panel module performance in the form of thesingle-diode equivalent circuit. The Five Parameters method isreliable in predicting the energy produced by the solar panels whenthe input data is limited. The results for using the Five Parametersin monocrystalline solar panels were Isc = 1.827 A, Imp = 0.662 A,Voc = 18.221 V, Vmp = 15.019 V, Pmp = 9.955 W. And the results inpolycrystalline solar panels were Isc = 1.926 A, Imp = 0.686 A, Voc =17.594 V, Vmp = 14.166 V, Pmp = 9.722 W. Based on the results; itwas concluded that the most efficient and optimised types of solarpanels on natural conditions in Sendang Biru Beach was themonocrystalline solar panel because it produced electrical outputpower of 9.955 W. Therefore, there could be a manufacturer ofsolar energy power plants to reduce the cost of electricity in thecoastal area, such as in Sendang Biru Beach.

In this study, a general building of medium size with an Energy Storage Systems (ESS)-connected Photovoltaic (PV) system (energy storage system that is connected to a photovoltaic system) was chosen to develop a tool for a better economic evaluation of its installation and use. The newly obtained results, from the revised economic evaluation algorithm that was proposed in this study, showed the effective return of investment period (ROI) would be 8.62 to 12.77 years. The ratio of maximum power demand to contract demand and the falling cost of PVs and ESS was the factors that could affect the ROI. While using the cost scenario of PVs and ESS from 2019 to 2024, as estimated by the experts, the ROI was significantly improved. The ROI was estimated to be between 4.26 to 8.56 years by the year 2024 when the cost scenario was considered. However, this result is obtained by controlling the ratio of maximum power demand to contract demand. Continued favorable government policies concerning renewable energy would be crucial in expanding the supply and investment in renewable energy resources, until the required ROI is attained.

It is becoming increasingly important to include information about power generation from renewable energy sources in the training of electrical engineers. Solar energy is arguably the most common renewable energy source in use today. Providing practical hands-on training on solar energy power generation today requires the use of photovoltaic panel devices which are used for transforming solar energy into electrical energy. In many developing countries, practical hands-on training on solar power generation is limited due to the cost of photovoltaic panel devices and so the training consists of theoretical and tutorial classes sometimes supported by remote and virtual laboratories. This paper presents an augmented virtuality tool where real-time information from a mobile device’s sensors is used directly within a virtual or computer generated environment. The tool provides a practical context for hands-on tutorial exercises on solar energy power generation.
