Indonesia has 442 GW total of potential renewable energy equivalence which can be used for electricity generation. However, the energy utilization in 2018 is only 8.8 GW or 0.019% of total potential renewable energy, while the biggest renewable energy potential is at 207.8 GWp. By also considering the growing number of household customers, utilizing the rooftop as the base of solar power plant generators can be an effective and efficient solution. The purposes of this research are to technically design and analyze the household-scale rooftop solar power plant potential with an on-grid system. Through the utilization of PVSyst 6.43 software and a variety of main components, this household-scale rooftop solar power plant potential performance planning is expected to generate 4.23 kWh / kWp per day.

Utilizing rooftops as a solar power plant system on the grid can be an effective and efficient solution to reduce electricity bills. This research aims to design and analyze the potential of 1215 Wp solar power plant rooftop with on grid system household scale in terms of techno economy. Using each of the two alternatives to the main components of solar panels and inverters, there were 4 variations of the component configuration design in this study. Variation 1 uses Canadian solar panels with solax inverters. Variation 2 uses Canadian solar panels with so far inverters. Variation 3 uses risen solar panels with solax inverters. Variation 4 uses risen solar panels with sofar inverter. Through PVSyst 6.43 software, with an average radiation average of 5.48 kWh/m2/day, the potential energy production of each variation of 1215 Wp rooftop solar power plant household scale are 1873 kWh, 1893 kWh, 1865 kWh and 1885 kWh. The investment cost of 1215 Wp rooftop solar power plant ranges from IDR25,220,000-IDR27,020,000 with Net Present Value ranges from IDR15,309,805- IDR17,421,839, Benefit Cost Ratio ranges from 1,489-1,588, Payback period ranges from 10.38 – 11.02 years and Internal Rate of Return value ranges from 8.8-9.56%.

Vietnam is a country of a great solar potential; solar technology is growing rapidly in Vietnam and investors are very interested in building solar power plants. Construction of the rooftop solar power stations can help owners reduce monthly electricity costs and even get economic benefits by selling excess electricity coming from a solar power plant (PV) to the utility grid. In this study, the design results of a rooftop grid-tied solar power station with the capacity of 26 kWp for a commercial building were introduced to have a basis to assess the operation ability of solar power station under solar radiation conditions in Hanoi city, Vietnam. The simulation results using the PVsyst program have made it possible to calculate the solar energy potential in Hanoi city, the power generation and efficiency of the grid-tied solar power station. Solar power has been applied in Vietnam since the 1990s but is mainly used for areas that were far from national power grid such as mountainous areas, islands. Small scale grid-tied solar power has been developed since 2010 and mainly is used for residential applications or small and medium scale consumers. The total capacity of electricity produced by solar power plants in Vietnam by 2017 was only about 8 MW; this value is very low as compared to the potential of solar power in Vietnam. This is due to the absence of the government support for the policy of developing solar power. In accordance with the current roadmap of raising electricity prices in Vietnam, construction investment of rooftop solar power stations is economically feasible while contributing to environmental protection and counteracting climate change phenomenon by reducing the amount of CO2 emitted into the environment.

Rooftop Solar

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.
