Abstract
The electricity demand share in the household sector will increase from 49% in 2018 to 58% in 2050 as predicted. This issue is particularly caused by the household growth number which may increase from 67 million in 2018 to approximately 80 million in 2050. For the household customer number are increasing, utilizing rooftop as the base of solar power plants can be an effective and efficient solution. In addition, the government regulation supports the acceleration and development of new and renewable energy. This research aims to analyze the technical economic feasibility of rooftop solar power plant system with a household-scale on-grid system in Semarang City. Through PVSyst 6.43 and RetScreen software also equipped with several primary components, this household-scale rooftop solar power plant investment plan is estimated to have an average revenue return estimated in 10 years later.

After obtaining the electrical energy production from the Rooftop Solar Power Plant in the research area and determining the investment costs for each component in the design of a household-scale rooftop solar power plant system variations 1, 2, 3, and 4, the result can be seen in the tables 5, 6, 7, and 8 below
Summary
The share of household electricity sector will increase from 49% in 2018 to 58% in 2050. To accelerate New and Renewable energy development, the government has established several regulations such as Peraturan Presiden No 4 in 2016 (Article 14) concerning the Electricity Infrastructure Acceleration prioritizing the use of new and renewable energy [2], Peraturan Menteri ESDM No 50 in 2017 concerning the Utilization of Renewable Energy. Sources as the Supply of Electricity [3], and Regulations of the Minister of ESDM No 49 in 2018 concerning the Use of Rooftop Solar Power Generation System by state-owned corporation Perusahaan Listrik Negara (PLN) customers [4]. By considering the growing number of household customers, utilizing the rooftop’s consumers as solar power generator base can be an effective and efficient solution. The purpose of this research is to analyze the techno-economic feasibility of rooftop solar power plant system with a household-scale ongrid system by the RetScreen Expert software utilization
