Abstract

Solar Power Plant (PLTS) as one of the renewable energy sources that is being focused on itsdevelopment. This article discusses the design and simulation of the performance of a 1 kWp rooftopsolar power plant using a Helisocope. The input data required by the Helioscope is PLTS technicalspecifications such as solar panel technology, inverter type, number and type of modules selectedand land area. The location data required by the PLTS system includes the coordinates, the type ofroof of the building, the environment around the PLTS and meteorological data. The 1 kWp PLTS roofsystem designed at the location that the author uses uses 7 pcs Canadian Solar 195 Wp panels, 1pcs 1 kW AEC inverter, installed on the roof of the building facing north, and connected to the PLNnetwork via a net meter. This 1 kWp rooftop PLTS is capable of producing an average daily averageof 5,48 kWh, 41,07 kWh weekly, 164,29 kWh monthly, and annual 1971,5 kWh. Energy productionvaries by an average of 8% per month with the minimum production in January of 135,1 kWh and thehighest in July of 184,5 kWh. The designed 1 kWp PLTS roof produces a performance ratio of 73,6%with the irradiation received in a year reaching 1859,2 kWh/m2. The initial investment required to builda 1 kwp PLTS roof is IDR. 20.000.000.

Abstract

Solar Power Plant (PLTS) is a renewable energy that converts sunlight into electricity.However, the construction of PLTS requires a large area of land so that for urban areas it is noteasy to get the required land. One of solution to this problem is to use the roof of the parkingbuilding as a rooftop solar power plant, the energy produced by the rooftop solar power plantcan be exported to the network because generally the energy demand for parking buildings isnot much. This paper discusses PLTS on the roof of parking buildings that have been built allover the world. The results of a review were obtained as many as 40 PLTS on the roof of theparking building which were built from 2010 to 2022 with a total capacity of 207,49 MW. ThisPLTS parking facility was built in the form of PLTS on the roof of the parking building, carportand parking canopy. Institutions that have built PLTS above their parking facilities includeairports, banks, malls, governments, water companies, recycling companies, pharmaceuticalcompanies, financial companies, car companies, hospitals, schools, stadiums and universities.

Abstract

The Ramada Bintang and Ramada Camakila hotels have pools of nearly equal water, but these two pools have different pumping and pumping systems. Ramada Bintang uses two pumps 5 Pk works 12 hours while Ramada Camakila uses two pumps 1.5 Pk work 24 hours, the condition of both pools have the same clarity and water quality. In this study, electrical energy measurements were performed on each pump and calculated chlorine, ph and number of people taking bath in each swimming pool. The average electricity consumption per day on the Ramada Bintang hotel pumping system is Rp. 106,080 while Ramada Camakila Rp. 74,640, so the difference in electricity consumption for a year in both hotels is Rp. 10,579. 068 with the same water quality ratio.

Abstract

The cleanliness of the solar panels is one of the factors that affect the energyproduction of a solar power plant. Solar panel cleaning is a solution to keep solar panels cleanso that energy production can be optimal. This article reviews research developments andcommercial products for solar panel cleaning, with the result showing various applicabletechniques and commercial products for solar panel cleaning purposes. There are two distincttechniques used in solar panel cleaning, manual and automatic. The manual cleaning method isa method that conducts any action to operate the system manually by humans. The automaticcleaning method is a method that is controlled directly by the system without the need forhuman interference. Commercial solar panel cleaning products include telescopic polesequipped with brushes and water pumps, a robot that is permanently attached to the solar panelsupport construction equipped with dry clean and water clean methods, a robot with portablesystems using long roller brushes, a convenient robot which has a remote vacuum cleanersystem, to a mobile cleaning system using a robotic arm.

Abstract

Solar Power Generation System (PLTS) is a power generation system that utilizes sunlight as a renewable energy source and a rooftop as a place for solar panels. This paper presents the results of a study of the potential of a rooftop-based solar power plant in the city of Denpasar by taking a location on the roof of the SD Negeri 5 Pedungan Diponegoro No. 60 Denpasar road using PLTS objects that have been installed. The study was carried out with the help of Heliospoce software. Based on the study, information was obtained that the potential of solar energy was 1912.8 kWh / m2 / year or an average of 5.2 kWh / m2 / day in the city of Denpasar. Sunlight that can produce electricity starts at 07.00 -18.30 WITA. The installed energy potential of PLTS is 3214.6 kWh with an angle corresponding to the roof angle of 30.96o. The result of the potential energy produced will be greater if the installation of PV uses the optimal angle (15o) that is equal to 3407kWh.

Abstract

Gedung Sewaka Dharma Kota Denpasar dibangun dengan konsep desain green building. Dengan konsep desain green building, gedung Sewaka Dharma diharapkan mampu menghemat energi di dalam pengoperasiannya. Konsep desain green building yang diterapkan antara lain, gedung dibuat dengan banyak jendela kaca, memakai sistem ventilasi vertikal, lingkungan di dalam dan di luar gedung yang hijau serta pemakaian solar sel untuk lampu penerangan luar dalam mengurangi konsumsi energi. Dari hasil studi yang dilakukan ada perbedaan antara perencanaan dan realisasi dalam pembangunannya. Suhu dan kelembaban yang tinggi mengakibatkan terjadinya pemasangan AC di masing-masing ruangan. Suhu dan kelembaban yang tinggi diakibatkan karena tidak berjalannya sistem ventilasi alami pada gedung tersebut. Hal ini mengindikasikan bahwa konsep green building yang diterapkan pada gedung Sewaka Dharma tidak mampu menciptakan lingkungan kerja yang nyaman bagi pegawainya.

Abstract

PLTS is a power plant that converts sunlight energy into electricity using photovoltaictechnology. Solar panels play an important role in PLTS, because solar panels capture solar radiationthen convert it into electrical energy. The development of solar panel technology is the key to supportthe development of PLTS. This article reviews about the development of solar panels in Indonesia asan important component to support the development of national solar power plants towards a capacityof 6500 MW by 2025. The review will be carried out on various aspects of solar panels including thenational solar panel industry, solar panels available in the domestic market, and the availability ofvarious panels. Data is obtained from the national panel industry, the PLTS project, the PLTS userassociation, the national EPC, the Ministry of Energy and Mineral Resources, and the national solarpanel vendor. The survey result shows there are 241 panels, both local and foreign production. Panelcapacities vary from 5 Watt to 500 Watt and panel voltages are available from 12 Volt, 24 Volt and 48Volt. Based on the survey, it is also obtained the average of Rp/Wp is Rp.18,853/Wp and the averageof W/m2 is 159,46 W/m2. Increasing solar panel production can be done by providing incentives tosolar panel producers in the form of product purchase guarantees and incentives to develop newfactories. Information regarding the current status of solar panels in Indonesia is expected to be aquick reference for people or institutions that need it, and can be used as an introduction to researchand application of PLTS in Indonesia.
