The paper provides basic information on the 2 kWp PV solar power plant with monocrystalline silicon solar modules installed on the roof of the Faculty of Sciences and Mathematics (FSM), University of Nis, and the equipment for the investigation of its energy efficiency depending on the real climate conditions. Furthermore, results of the simulation and experimental determination of the energy efficiency of the PV solar power plant at FSM in Nis, in the period from July 1, 2013 to January 1, 2014, are given. It was found that in this time period the average values of the experimental and simulation calculated energy efficiencies of the PV solar power plant were 9.52% and 8.44%, respectively. The increase in the ambient temperature caused a decrease in the PV solar power plant energy efficiency; with an increase in ambient temperature by 1 ?C, the experimental energy efficiency decreased by 0.22%, and the simulation calculated energy efficiency decreased by 0.07%. The obtained data could be used for the planning and application of PV solar power plants in places with a similar climate.

ABSTRACT Renewable energy is potential alternative energy to replace the central role of fossil energy which has been going on since the early 20th century. The solar power plant is alternative energy, especially for households and industry, and can be designed as a hybrid power plant consisting of solar panels, batteries, an automatic transfer switch (ATS), and a grid. This research will focus on developing ATS based on a microcontroller. It functions to regulate the load supply automatically from the three sources of electrical energy, like solar panels, batteries, and grid while the microcontroller functions to monitor the transfer of power from the solar power plant to grid and voltage movements in the system so that current and voltage data can be recorded from time to time to improve system reliability, effectiveness, and efficiency of the tool. ATS components consist of MCB, magnetic contactor, timer H3CR, relay, 2000VA inverter, solar charge controller 100A, NodeMCU ESP8266 IoT, and battery 12V 100AH. This research is conducted in one year to produce ATS based on a microcontroller that can automatically regulate the supply of loads from the three sources of electrical energy with a good level of efficiency and stability.  Keywords: solar power plants, hybrid power plants, an automatic transfer switch.  ABSTRAK Energi baru terbarukan merupakan energi alternatif yang potensial untuk menggantikan peran sentral dari energi fosil yang telah berlangsung sejak awal abad ke 20. PLTS merupakan salah satu energi alternatif penyedia energi listrik untuk rumah tangga dan industri serta dapat dirancang sebagai sistem pembangkit listrik tenaga hibrid (PLTH) yang terdiri dari panel surya, baterai, sistem pengaturan beban atau ATS (automatic transfer switch) dan jaringan PLN. Peneltian difokuskan pada pengembangan sistem ATS berbasiskan mikrokontroler. ATS berfungsi untuk mengatur suplai beban secara otomatis dari ketiga sumber energi listrik yaitu panel surya, baterai dan PLN sedangkan mikrokontroler berfungsi memonitor perpindahan daya dari PLTS ke sumber PLN dan pergerakan tegangan pada sistem sehingga dapat dilakukan pencatatan data arus dan tegangan dari waktu ke waktu sehingga dapat meningkatkan keandalan sistem, efektifitas dan efisiensi alat. Komponen ATS terdiri dari MCB, magnetic contactor, timer H3CR, relay, inverter 2000VA, solar charge controller 100A, NodeMCU ESP8266 IoT, dan baterai 12V 100Ah. Penelitian ini akan dilakukan dalam periode satu tahun menghasilkan ATS berbasiskan mikrokontroler yang dapat mengatur suplai beban secara otomatis dari ketiga sumber energi listrik dengan tingkat efisiensi dan kestabilan yang baik. Tim penelitian ini tediri dari 3 orang dan berasal dari program studi teknik elektro, IT PLN.  Kata kunci: pembangkit listrik tenaga surya, pembangkit listrik tenaga hibrid, pengaturan suplai beban.

The object of research in the chapter is the solar power plant as the source of additional economically expedient power supply of the electrical energy consumer. The purpose of this research is to analyze the options for the layout of solar power plant, taking into account the solar energy potential of the district, the design features of the proposed location, the load curve of the consumer, and the cost of the generated electrical energy. The chapter presents the results of calculation and selection of the parameters of solar power plant elements on the roof of the consumer's production building. The chapter presents the results of research of the dependence of the cost of the electricity generated by the solar power plant on the number of installed panels, which in order to increase the realized solar energy potential of the district also allows adding photoelectric modules and accumulating devices in the layout of the operating station at tariff growth. The chapter presents the results of researching these areas, that are conducted by the authors and which are completely original.

Indonesia is a country that is geographically located right in the equator and variously advantage and the wide for the use of solar energy. Indonesia has a relatively high radiation level, which is 4.80 kWh / m2 / day. Cemara Island is a tourist place but does not have electricity from PLN because access to its location is still difficult to reach. So from that chosen the planning system for the use of electrical energy using solar energy. However, economic analysis is needed so that the estimated weaknesses of the off-grid solar system can be estimated so as to reduce the risk of losses. The testing of each component in the Solar Power Plant system also needs to be done to determine the condition and quality of the components to be used. The economic analysis of the Cemara Island Solar Power Plant System with an initial investment of Rp 52,553,000, in scenario 1 uses interest at 6%, then in scenario 2 without using interest. Through calculations by looking for the value of COE (Energy Cost), NPC (Net Present Cost) and BEP (Break-Even Point), so that costs can be calculated by the manager with the number of 11 managers per month.

The Cost

This community service program aims to implement a Solar Power Plant (PLTS) to provide electrical energy in tourist areas called rice field tourism, in order to reduce the cost of purchasing electrical energy for managers. Besides, it is also a means of education for visitors to introduce green energy in the future. The design of PLTS is adjusted to the requirements of the load that will be served at the tourist attraction. Before carrying out development, the Team first conducted outreach to local residents to introduce technology in rural areas. After the rotating program for managing tourism objects, in this case BUMDes Johar Mandiri, was given training in the operation, maintenance / maintenance of the solar power generation system, so that after the program it was able to solve the troubleshooting that occurred both in the generation system, control and distribution system. The resulting capacity of the Solar Power Plant in this Sawah Tour is 3500 WP which is used to meet all lighting needs. With this program, managers can reduce costs by Rp. 3,000,000 / month for electricity needs.
