Investigation of Solar Photovoltaic (PV) Performance in Surakarta City for Design of Home Energy System

摘要

The solar radiation energy is a major source of energy in the Earth. That is abundant. The use of solar radiation energy is a solution to the limited energy of fossil fuels. This research was carried out in Surakarta, Indonesia. Surakarta and its surroundings are located near the equator so that this area gets solar radiation throughout the year with almost the same duration, about 12 hours. The research method is calculating the electrical energy of PV system due to the sun irradiation. The next step was to calculate the cost of using PLN(Perusahaan Listrik Negara) electricity (conventional Electricity) for 25 years. The final step was to compare the installation cost of the PV system with conventional electricity consumption cost for 25 years. The power tariff 1300 VA, instalation PV system cost is IDR 292,805,852 and total cost of conventional electricity is IDR 865,791,351. The power tariff 900 VA, instalation PV system cost is IDR 192,437,852 and total cost of conventional electricity is IDR 487,408,464. The power tariff 450 VA, instalation PV system cost is IDR 148,157,852 and total cost of conventional electricity is IDR 75,133,758. The development of PV systems for home energy system can be used for alternative solutions for the supply of electricity, especially in Surakarta and surrounding areas.
