The use of solar PV system in Indonesia has expanded to various field and area. One example is residential buildings in urban areas. This article discusses calculation methods for designing a solar power generation system that is applied to residential buildings, such as homes, offices, or colleges. Electricity generated from the solar home system (SHS) is used to support many kinds of electrical equipments, where the electrical equipments are used by building occupants in their daily life. The calculation method is considered from the potential of solar energy and the reliability of the on-site system to generate electricity. The system is designed in an off-grid topology by exchanging connections with the public electricity grid owned by PLN. Calculation results shows that this SHS has a generation capacity of 1 kWp, 24 V 300 Ah battery storage, and a 200 W inverter. This SHS can reduce electricity usage in this sector by 18.2 kWh in average every month.

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 ele...

The use of solar photovoltaic (PV) system has grown significantly in Malaysia after Renewable Energy Act has been gazetted in 2011.The objective of this paper is to highlight the technical and economic analysis of solar PV DC system to generate enough energy for residential customer group that consumed 200 kWh per month so that they are less dependent on energy from the utility grid. The results are then compared to the solar PV AC system with similar load setup. The methodology involves gathering solar energy resource, configuring daily load demand, sizing PV array, battery bank and inverter and lastly simulation of the design system by using Homer software. Based on Homer simulation, the solar PV AC system required slightly larger PV array sizes than the solar PV DC system to compensate losses due to the inverter efficiency which is not counted in DC system.Moreover, the solar PV AC system is almost 8.0% more expensive with 6% higher COE than the solar PV DC system due to the pre...

As with the growing GDP, developing market economy of Bangladesh is raising question on energy sustainability. Although having the infinite possibilities of harnessing solar energy, it could not be utilized properly as 90% of the urban rooftop solar panels are idle. The proposed system can work with the existing rooftop solar panels by using them as the source for powering the DC appliances of the apartments and store the excess energy in the 48V battery bank for later use. National grid connection is also kept as a backup source for powering the appliances when solar irradiance is unavailable and the batteries are all drained up. The reason of being exceptional of this project is use of DC appliances instead of converting the DC solar energy into AC which is inefficient and at the same time costly. This project successfully shows that those idle rooftop solar panels can utilized in the most effective and efficient ways while saving money and contributing to the nation's energy sustainability.
Dc House: An Alternate Solution for Rural Electrification
International Journal of Trend in Scientific Research and Development, 2019
In today's date, India is a large consumer of fossil fuel such as coal, crude oil etc. The rapid increase in use of Non renewable energies such as fossil fuel, oil, natural gas has created problems of demand & supply. Because of which, the future of Non renewable energies is becoming uncertain. Now a day's electricity is most needed facility for the human being. All the conventional energy resources are depleting day by day. So we have to shift from conventional to non-conventional energy resources. In this the combination of two energy resources is takes place i.e. wind and solar energy. This process reviles the sustainable energy resources without damaging the nature. We can give uninterrupted power by using hybrid energy system. Basically this system involves the integration of two energy system that will give continuous power. Solar panels are used for converting solar energy and wind turbines are used for converting wind energy into electricity. This electrical power can utilize for various purpose. Generation of electricity will be takes place at affordable cost. This paper deals with the generation of electricity by using two sources combine which leads to generate electricity with affordable cost without damaging the nature balance.
In the world of today, green energy and a reduction in fossil fuel usage are being advocated. Also energy consumers look for ways of reducing cost of operating diesel generators. One way to achieve this is by employing solar photovoltaic (PV) systems. In this study, a demonstration of installation of a stand-alone, purely DC solar (PV) home power system for low power consuming devices as alternative power source was exemplified. A prototype PV system was set up by calculating and determining total load requirement in an installation, calculating a sufficient ampere-hour to carry the load and determining a solar system capable of effectively sustaining the setup on a continuous basis. Optimal PV sizing was carried out and adequate battery capacity determined. After the installation was carried out, tests were carried out to examine the effectiveness of the installation. It was found out that the installation can adequately replace conventional lighting systems in homes and offices and supply power to many commercial and office electrical appliances. The system consumes less electric energy as it operates on 12 V DC at all times. A form of clean energy is produced and in the long run the consumer saves a lot of resources. The system is recommended to be adopted in developing countries especially in grid-deprived areas.

Malaysia is moving forward by promoting used of renewable energy such as solar PV to the public where it is generated at the distribution voltage level. The fluctuation of fuel prices becomes main concern to the consumers since it affecting the electricity tariff. The objective of this project is to design a self-consumed DC power system for a residential house from renewable energy resource which is solar PV that it will independent from the utility grid. The methodology proposed are configuring daily load demand, sizing PV array and battery bank and simulation of the design system by using PVsyst. Based on solar energy resource, the optimum PV array size is 2.0 kWp while the battery bank size is 700 Ah at 48 V which is designated for 4 days of autonomy. The system could meet 100% of load demand throughout the year with 67.9% of performance ratio. The loss to the system is contributed by the temperature effect to the PV module, unused energy because of battery full capacity, converter and battery efficiencies. Using this concept, the proposed design setup is expected to benefit the residential consumers in reducing utility electricity consumption up to 2,434 kWh per year and avoiding 1.7 tons of carbon emissions into the environment annually.
