Solar energy is being used in many ways, but the easiest to trap solar energy is solar pond. Solar Ponds absorb the solar energy and the absorbed solar energy will be taken away by a streaming fluid. A non-convective solar pond has been constructed to investigate the temperature variations of it, in the weather conditions of Pachapalayam, Coimbatore. Solar pond with a surface area of 1.7m2, a depth of 0.5m has been built-up and an inflexible surface is maintained at the bottom using a dark-colored (blackened) HDPE sheet, thermo styrene for capturing the heat in a good amount. Measurement of the temperature at depths of 0.05, 0.1. 0.2, 0.25, 0.3, 0.35, 0.4 0.45, m from the base of the pond and ambient temperature were taken using washer type thermocouples. Solar radiations were taken during a period of 10 days of experimentation using a solar power meter. In this experimental work investigated the performance of solar pond with NaCl salt and coal cinder |
