This project describes the drying of grapes using a solar powered air blower and a heating module (peltier chip) .The preparation and maintenance of grapes has been considered to be a major complex issue for a long time. In order to achieve more product and higher marks and achieve customer satisfaction more attention is given to quality features. Quality factors including color, size, taste were very important as they would differ from the dehydration process. This project is used to reduce drying time by using solar energy. Solar power plants are important in the tropics, which face challenges in accessing electricity, which severely limits the refrigeration usage as storage of agricultural products is limited, and the need to make products competitive overseas. In this project, the solar energy used to dry food is described; it is thought that hot weather conditions are favorable during the summer season. A DC drive for suction fan operation is used to send atmospheric air into the system and the air temperature is increased using a peltier chip placed in the air. DC's utility system is powered by a battery charged with the help of solar panels and electricity supply. It works well that the design will be able to shorten the final product time rather than the traditional method.

Indonesia has more than 17,000 islands and has plenty of beautiful beaches and underwater spots which have great potential for maritime tourism. Tourism was ranked 3rd on Indonesia's foreign income and plays an important role for the country’s ecomony. Despite having potential advantages, the government has not yet maximized its efforts to develop the attractiveness of its maritime tourism. Beside the beautiful spots Indonesia is also blessed with all year long sun shine, which could be tapped as renewable and green energy as substitution to fossil fuel. Refer to these great advantages of natural resources the research was aimed to support the government’s program in developing its maritime tourism and to promote the use of green and renewable energy by designing a solar-powered tourism recreational boat which has 12 meters of length. The paper is focused on the design of solar energy and its electrical system, which includes conversion of solar energy to electrical energy and store it in the battery, the required electrical power is also predicted based on the appliances and equipment installed in the boat, the optimum attachment of solar panels on the boat structure is also calculated. All the methods and information we use are obtained from literature study, discussion with experts, and surveys to Jagur as solar-powered electric boat from Universitas Indonesia.

Solar Water Heaters

1961 has been a year of outstanding success in celestial applications of solar energy since, at the year’s end, no less than a dozen satellites are in orbit, carrying solar-powered radio and television transmitters. The first satellite to carry silicon cells into orbit, Vanguard I, is still transmitting after nearly four years of service, despite serious deterioration of its silicon cells due to the intense radiation of the Van Allen belt. Three major scientific conferences on solar energy were held during the year, with the addition of nearly two hundred papers to the growing body of literature on the subject. The largest of these gatherings, the United Nations Conference on New Sources of Energy, brought more than 500 participants from 80 nations together in Rome. A major improvement in small vapor-cycle power plants, developed at the National Physical Laboratory of Israel, was described and demonstrated in actual operation. Significant progress in direct solar-electrical converters of three types was reported, but costs are still far too high for terrestrial use. Solar water heaters continue to be the only commercially available devices which use the sun’s heat; 350,000 are now in use in Japan, while more than 20,000 units have been manufactured in Israel. The most pressing need for solar-activated equipment is found to exist in the field of refrigeration for the preservation of food and medicine in tropical regions where electricity from conventional sources lies far in the future. Intensified research is needed in all aspects of solar energy utilization to bring costs down to the point where the people of the world can afford to use the “free energy” from the sun.

The need of electricity in every ship are very diverse. Power plants for using diesel as an engine can also come from sunlight as an alternative source of electrical energy. The measurement of solar energy in Indonesia is 4.8 kWh /m2. This renewable energy is in suitable for the Indonesian topography. Thus, the energy from the sunlight around the equator is so abundant that its availability is always available throughout the year, except when it rains. Utilization of solar energy can be used as a substitute for conventional energy which is starting to be limited and the price is quite expensive. Therefore, the data that are presented in this paper comes from publications, manufacturers, relevant official government documents, scientific publications and other publications. Utilization of solar energy as electrical energy can be done by using solar panels mounted in ships. The generated electricity can be used to turn on electrical equipment and send lights at night, and can be used as fishing aids. The use of solar power plant can also have a positive impact on fishermen, such as improving health, economy, environmental sustainability, and building independent fishermen.

Power System Performance

Having an exciting array of applications, the scope of unmanned aerial vehicle (UAV) application could be far wider one if its flight endurance can be prolonged. Solar-powered UAV, promising notable prolongation in flight endurance, is drawing increasing attention in the industries’ recent research and development. This work arose from a Bachelor’s degree capstone project at Hong Kong Polytechnic University. The project aims to modify a 2-metre wingspan remote-controlled (RC) UAV available in the consumer market to be powered by a combination of solar and battery-stored power. The major objective is to greatly increase the flight endurance of the UAV by the power generated from the solar panels. The power system is first designed by selecting the suitable system architecture and then by selecting suitable components related to solar power. The flight control system is configured to conduct flight tests and validate the power system performance. Under fair experimental conditions with desirable weather conditions, the solar power system on the aircraft results in 22.5% savings in the use of battery-stored capacity. The decrease rate of battery voltage during the stable level flight of the solar-powered UAV built is also much slower than the same configuration without a solar-power system.

Electric vehicles were invented as an alternative to save fuel and to make more environment-friendly vehicles. With the increase in pricing for fuels, all are looking at effective alternatives for fuelled vehicles. Although electric vehicles [EV] are alternatives for our daily means of travel, they have not been very effective with the distance we can travel by fully charging them. The problem with EV is that once fully charged they may run for about 60 km. But considering our society, most of us travel more than 60 km every day. An alternate EV will make a better future. In this project we have aimed at making EVs more efficient and effective for normal usage. We have implemented a prototype of a new circuit with two batteries where each battery works alternatively. Apart from this, we have used solar panels to charge these batteries with solar energy.

Solar energy is a renewable energy abundant throughout the year in a tropical weather country like Malaysia. This paper investigates the viability of using solar PV systems as a cost-saving measure to supply electricity for Taylor’s University (TU) daily energy usage. Experimental values were compared with theoretical values and analyzed in this paper. In this experiment, four photovoltaic (PV) panels connected in parallel were linked to a maximum power point tracking (MPPT) charge controller acting as a voltage regulator. A lead-acid battery was also coupled to the controller that acts as an energy storage to store the harvested solar energy from PV panels and discharge it in electricity. Temperature sensors connected to an Arduino UNO were placed at different locations on the solar panels to monitor for irregularities in the temperature of the panels. The amount of electricity produced was calculated using the data obtained. The results showed that using a larger PV system will generate much more electricity and create a high return on investment (ROI) if the solar panels absorbed sunlight under good weather conditions, thus bringing forward a potential solution to reduce TU’s electricity consumption.

Today our Earth is facing severe problems such as global warming, air pollution and ozone layer depletion etc. One of the reasons for this problem is increased usage of fossil fuel in the recent years by humans. The renewable source of energy hence turns out to be indispensable source of energy for the present and future generations. Solar energy is one of the renewable sources of energy which can be used for various applications. The newly designed rice puffing machine is likewise powered by solar energy. The solar powered rice puffing machine is designed and developed based on the general principle of rice puffing method. Solar rays are collected from open area using solar panels and used to charge the battery thus converting the solar energy into electricity which powers the rice puffing machine. The main aim of the project is to reduce the human effort and number of labours required involved in the rice puffing process. Mechanical energy of the motor is used to drive the shaft which is welded with mesh. The rotational movement of the shaft accomplishes the mixing of rice with hot sand to puff the rice. The electric blower flushes out the puffed rice. The heat energy required to heat the sand is provided by Bio-Gas operated burner.
