In this paper design; fabrication and testing of micro-channel solar cell thermal (MCSCT) tiles has been discussed. Solar simulator for an indoor testing of micro-channel solar cell thermal tiles has also been developed. Fabricated MCSCT tile consists of single solar cell; micro- channel and fan for extraction of heat from bottom of solar cell. Single MCSCT tile has been termed as case-I. Similarly; two MCSCT tiles which are connected in series have been termed as case-II. The performance evaluation in terms of electrical efficiency; thermal gain; overall thermal energy and overall exergy of both cases has been carried out in indoor conditions on various intensities. It has been also found that the electrical efficiency is higher in case-I as compared to case-II. On the other hand the thermal out put of case-II is higher than case-I on same intensity and mass flow rate. It has been found that the average electrical and thermal efficiency of newly designed and fabricated MCSCT tile is 12.4% and 35.7% respectively. This economical solar simulator can be used by manufactures for testing of different type of photovoltaic tile as well as photovoltaic modules
