Abstract

Simulation studies for a PV system would be useful for planning before real implementation, and to predict the cost for a large scale PV system. This work is to simulate a 3 kWp rooftop photovoltaic (PV) system under the climate of Surabaya, Indonesia. SolarGIS PV Planner and RETScreen simulation tools are used in this work. The simulation results are then compared with a full year of measurement results. The results of simulations show that a 3 kWp rooftop system could produce electricity of 4,200 kWh per year, while in the real measurement energy production is found about 3,898 kWh per year. There were slightly different results values of energy output between  Simulation and real measurement of the PV system, however statistically it still can be accepted. Economic analysis shows that, under current conditions, a grid-connected PV system investment would give about 5 years of the payback period. Environmentally, the 3 kWp PV system would provide a reduction of CO2 emission of about 2.7 tons per year.

Abstract

Abstract—A study of energy consumption in the Keluwih canteen at the University of Surabaya (UBAYA) has been conducted as a first step to determine the design of the use of alternative energy that is appropriate in the canteen. The study began with conducting an energy consumption survey in the Keluwih canteen to find out the energy needs in the canteen. This energy consumption is measured by the energy used for lighting (lamps), air conditioning (AC), and other electronic equipment (television, blenders, rice cookers, electric stoves, etc.) and fuel used for cooking. Data were obtained from a questionnaire given to booth the canteen manager and tenants in the Keluwih canteen. From the data obtained, it can be knewn the energy consumption map in the Keluwih Canteen and based on the survey that has been done can be concluded that the energy consumption in the Keluwih Canteen is dominated by electricity which is around 600 kWh/day. Keywords: energy consumption, keluwih canteen, survey, questionnaire, electricity Abstrak—Telah dilakukan studi konsumsi energi di kantin Keluwih Universitas Surabaya (UBAYA) sebagai langkah awal untuk menentukan desain pemanfaatan energi alternatif yang tepat guna di kantin tersebut. Kajian diawali dengan melakukan survei konsumsi energi di kantin Keluwih untuk mengetahui kebutuhan energi di kantin. Konsumsi energi ini diukur dari energi yang dipergunakan untuk penerangan (lampu), pendingin ruangan (AC), dan peralatan elektronik lainnya (televisi, blender, rice cooker, kompor listrik, dll.) serta bahan bakar yang dipakai untuk memasak. Data diperoleh dari kuesioner yang diberikan kepada pengelola kantin serta penyewa stan di kantin Keluwih. Dari data yang diperoleh dapat diketahui peta konsumsi energi di Kantin Keluwih dan berdasarkan survei yang telah dilakukan dapat disimpulkan bahwa konsumsi energi di Kantin Keluwih didominasi oleh energi listrik yang jumlahnya berkisar 600 kWh/hari. Kata kunci: konsumsi energi, kantin keluwih, survei, kuesioner, energi listrik
