Abstract

This research work reports the results of monitoring the temperature variation in three experiment models of natural circulation PV powered water heater of capacities 40, 90 and 140 liters built at the female hostel of Nnamdi Azikiwe University, Awka, Nigeria. From the general observations, the temperature of the systems does rise from ambient to about 45oC by midday. The increase in temperature gets to about 75oC by 3pm local time and gradually drops to about 38oC by 6:30pm local time. It was observed that in early mornings between 6-7am, the peak period for hot water demand by students, the temperature is about 10oC below ambient temperature of a fresh-water from the municipal supplies. It is imperative, from the research findings for a design modification of the system which is suggested in this paper. Moreover, the paper reported cost comparison of PV water heater with electricity for equivalent hot water demands.
