Pemanfaatan Listrik Tenaga Surya Sebagai Pasokan Listrik Untuk Menghidupkan Mesin Pompa Air Masyarakat Dusun Cilatak, Desa Sukadana, Kecamatan Ciomas, Kabupaten Serang, Banten

The Community Service program activity of the Electricity and Renewable Energy Faculty lecturer team at the PLN Technology Institute for the 2019/2020 fiscal year was carried out in Sukadana village, Ciomas district, Serang region, Banten precisely at RT 011 RW 003 Cilatak hamlet. The selection of Sukadana village as a place to implement Community Service is because this village is still experiencing problems in the construction and development facilities and infrastructure. The problems that are currently being experienced by villagers regarding the clean water distribution for ablution of villagers in the mosque. During this time for ablution in mosque, villagers only rely on water from mountain springs whose distribution relies on gravitational pressure through a plastic hose and accommodated in a large tub located beside the mosque. In addition to being used for ablution, water is also used by villagers to bathing, washing, etc., so that when used for ablution sometimes it is no longer clean because it has been mixed with soapy water used for bathing and washing. Based on those problems, our team provided solution to partner in the form of infrastructure development and clean water supply by reconfiguring the clean water distribution installation for ablution in the mosque by installing solar water pump. The method used in the implementation of this Community Service activity is to approach the villagers during the survey through interviews by providing solution to the problem and conducting questionnaires and socialization in the form of a brief education. The results of the activities have been done by installing 2 units of DC water pump @180 Watt, 4 units of polycrystalline solar modules @100 Wp, 2 units of battery @100 Ah 12 V and 2 units of solar charge controller. With the implementation of Community Service activities in Sukadana village, aside from being able to help overcome the problems faced by partner, besides that it can provide progress and development of infrastructure for partner village and the existence of a partnership that makes that village as IT PLN assisted village.

Performance analysis of DC type variable speed solar pumping system under various pumping heads

This paper proposes a method for the modelling, simulation and analysis of solar PV water pumping system. A submersible type variable speed DC water pump system is considered in this study under different pumping heads (50 m, 60 m and 70 m) and for 8S × 3P PV array configuration. The hourly electrical performance of the PV array was estimated from the maximum power points of the I-V curves, as the maximum power point tracking (MPPT) controller continuously optimizes the output power of the PV array. The performance equation which relates the flow rate of the pump with pump head and power input to the pump is modelled from the manufacturer’s performance curve with curve fitting technique. Using the generated equation and the calculated hourly power output data, the hourly performance of the solar driven water pump system was estimated for of different pump head. The analysis and simulation results show that a lower pump head results in higher flow rate regardless of the variation in solar irradiation level. The obtained result also indicated that an increase in solar radiation intensity resulted in an increasing of the pump flow rate, pump efficiency and system performance.

Climate-Smart Initiatives in Sri Lankan Agriculture Sector: Experience and Perspectives in Solar Powered Water Pumping for Sustainable Crop Production

The availability of low cost and long-lasting water pumping technology is a dream of every farmer. In Sri Lanka, fuel or electricity-powered water pumps are used to irrigate thousands of hectares of field crops, Vegetables, and fruits. Based on the International Water Management Institute (IWMI) survey conducted in the year 2000, there are about 50,000 agro-wells in the dry zone of Sri Lanka. More than 110,000 pumps are used to pump water from those wells. The fuel cost is the biggest burden for the farmers, which results in a high cost of production. The use of solar energy for water pumping is a promising alternative to conventional electricity and fuel-based water pumping systems. Solar-powered water pumping is based on photovoltaic (PV) technology that converts solar energy into electrical energy to run a DC or AC type water pump. This paper presents a comparative analysis of economic and environmental benefits associated with solar water pumping systems against fuel-based water pumping systems. The analyses were based on practical experience over 50 acres of land cultivated for export-oriented Green Cucumber by 100 members of Tempitiya Farmer Organization in Ampara District of Sri Lanka. It concluded that the solar water pumping system is advantageous compared to a fuel-based pump in terms of economic and environmental aspects.

Increasing the output power of solar panel by using cooling system

Solar panel is a device to convert light energy from the sun into electrical energy, most of solar panel is made from semiconductor such as silicon. Solar panel is still having many disadvantages such as expensive prices, low efficiency, the power output that depended on light intensity and temperature, etc. During the day, solar panel temperature could increase and affect the power output. It is found that temperature would reduce solar panel voltage output that also reduce the power output. In this research, 100WP Monocrystalline solar panel power output will be enhanced by using cooling system to reduce the temperature of the solar panel. Cooling system of the solar panel is applied by flowing the water on the surface of the solar panel using 12V DC water pump. The experiment starts from 11:00 AM to 01:00 PM. The result of this experiment is the power output of the solar panel increased up to 5.79 Watt with the average about 2.96 Watt and the temperature of the solar panel decreased by 20.99°C. The temperature of the solar panel without cooling is about 52.83°C and with the cooling system is about 31.85°C.

Investigation of Standalone Solar Photovoltaic Water Pumping System With Reduced Switch Multilevel Inverter

Solar photovoltaic powered water pumping systems are becoming very successful in regions where there is no opportunity for connecting the grid. The photovoltaic technology converts solar energy into electrical energy for operating DC or AC motor-based water pump. In the case of a solar AC motor water pump, it engages two energy conversion stages (DC-DC and DC-AC) in the power conditioning unit. This usually resulted in increased size, cost, complexity and decreases efficiency of the entire system. In addition, the existing two-level inverter (DC-AC) stage generates higher harmonics in output voltage that deteriorates AC motor performance. As a consequence, a single energy conversion stage with more than two-level output voltage could be possible by utilizing multilevel inverters which replaces two-level inversion stage easily to get higher levels of output voltages as well for extracting best results from the motor. Moreover, they can able to operate with reduced switching frequency that certainly reduces switching losses. Still, the increased voltage levels comprise a higher number of power semiconductor switches, cumulative voltage stress and switching losses are making the system more complicated. In this paper an innovative seven-level inverter with five switches had been taken to investigate 0.5 H. P single phase induction motor water pump. This topology ensures minimum switching losses, lowering size along with less installation cost. In order to provide better insight into the working and performance of this proposed topology the simulation results performed in the MATLAB / Simulink environment and hardware implementation are depicted.
