Solar Street Lighting a street lighting solution for areas or areas that are not within the PLN network area or for lighting efficiency using solar power. The use of public street lighting, although it has several advantages, there are still disadvantages in the field conditions, including the improper placement of the lighting so that it is blocked from sunlight, the use of inappropriate materials, unsuitable height of poles and lack of maintenance which results in not optimal utilization of solar energy. In this study, an analysis of the power efficiency of solar street lighting in the District of Ternate Island will be carried out by conducting direct observations and measurements in the field. The results showed that the maximum voltage for street lamps that were not blocked by trees was 23 volts, while those that were blocked by trees were 19 volts. The lighting strength of the street lights that are blocked by trees is 9 lux, while those that are not blocked by trees are 10 lux. The amount of input voltage for the solar panels affects the strength of the lamp lighting

power generation system of a size able to meet the electric power requirement for general illumination of the electric laboratory at Afyon Kocatepe University was dimensioned and installed. While determining the installation power of the hybrid wind–solar power generation system, the regional wind–solar energy potential and the magnitude of demanded power were the most important factors. It was decided to supply 400 W of the total 500 W of electric power required by the lamp group used for illumination of the electric laboratory from solar panels and 100 W from a wind turbine according to the wind–solar energy potential of the region and the cost analysis. For the hybrid energy-generation system that was designed and installed, by considering the data for the annual mean sunshine period and wind speed, the most suitable system components and thus the installation cost were determined. The electric power generated by the hybrid wind–solar power generation system and the electric power consumed by the laboratory illumination elements supplied with this system during one year were compared. According to the 12-month measurement results for power generation and consumption in the installed system, it was observed that the generated electric power was higher than the consumed electric power. Consequently, by not paying the total electric bill for electric power consumed by the general illumination elements, use of it for other education expenses was made possible. Besides, the installation costs in Turkey were compared with those in the countries of Denmark, Germany, Spain, and Portugal, where two important components of the dimensioned and installed hybrid wind–solar power generation system – wind and solar energy – are used effectively.

The article presents an analysis of the state of development of solar energy in Europe and  the  Republic  of  Belarus  for 2020.  An algorithm for increasing the efficiency factor of  solar power plants by localizing the solar trajectory depending on the latitude and longitude of the area has been proposed. In particular, taking into account the angle of the Sun position above the horizon and the azimuth angle of the Sun, the increase in the efficiency factor of solar power plants for the Republic of Belarus is calculated. Based on this algorithm, a program has been written that makes it possible to draw a diagram of the solar trajectory. An analysis has been made of the degree of localization of solar energy for solstice days in 6 oblast (regional) centers of the Republic of Belarus; it is found that the highest intensity of solar radiation is observed in Brest and Gomel, the average in Grodno, Minsk and Mogilev, while the lowest one – in the city of Vitebsk. A comparative analysis of the solar trajectory of the city of Berlin (Germany) with the city of Gomel and the city of Brest is carried out. Recommendations have been developed for the effective operation of solar power plants in the oblast (regional) cities of the Republic of Belarus during the year in an autonomous and combined mode of operation. The obtained numerical calculations of the solar trajectory make it possible to optimize the orientation of solar panels for permanently installed panels and for automated solar tracking systems, as well as to select the optimal configuration of the power plant equipment for any geographic area.

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
