Abstract

This study has been carried out to design a number of storage units which could improve the utilizability of solar energy by offering convenient means to store it. The proposed units are systematically tested to establish their reliability in actual operations. One of the prominent features of the present storage units is that each design is meant to drastically improve the thermal response of solar systems which would definitely offer extreme convenience to whoever uses it. Also sought in the present study is to elicit ideal operating conditions during the storage and extraction phases of solar energy once it is delivered to the storage unit. The present study has confirmed the potential use of the proposed units with their applicability in capitalizing the sun's energy.
