Abstracts: Obtaining hot water is energy intensive. In developing nations, heating water for bathing and cooking is often the most expensive and time-consuming process in the household energy budget. Solar hot water systems could present a sustainable solution for poor households if the upfront prices of these systems were competitive with current methods. Our team is developing a low-cost residential solar hot water system for developing countries. This system will be installed into existing water plumbing and provide 100 litres of 40°C water for early morning bathing. The system will be constructed using local materials and labour to minimize cost and maximize impact. If we make two junctions of different metals and If hot junction is attached to solar collector plate & keep cold junction in cold water (at bottom of tank) definitely emf will be generated in circuit. The major market barrier for solar water heaters (SWHs) is installed cost. This project addresses this barrier by working to evaluate innovative solutions that reduce the installed cost of a SWH and be cost-competitive. We are going to use concept of see beck effect for producing current and subsequently heat. This project also addresses findings of parameters like number of junctions, material for conductors and its dimensions, heat transfer and there are some other ways to better utilization of domestic solar water heater.
