EXECUTIVE SUMMARY: This study aimed to develop and construct a solar powered electronic controlled bat repellent system out of locally available materials. Such device can be very useful to counter the various problems caused by bats. The device is compact, cheap and it does not cause any pollution unlike the other chemical repellents. Specifically, this study aimed to determine the effectiveness of the solar powered electronic controlled bat repellent system device as revealed by the amount of fecal matters collected during the experimentation. It was conducted at the University of Rizal System Morong Campus, on the sides of the Isidro S. Rodriguez building at the graduate library 2nd floor, room 203 during the academic year 2017-2018. The developmental, descriptive and experimental methods of research were applied in the construction of a solar powered electronic controlled bat repellent system device. It used different set-ups for the samples to determine the level of effectiveness of the said unit according to the purpose of the study. The data gathered in the study were statistically treated using qualitative description, weighted mean and independent t-test. The study tested the null hypothesis that there is no significant difference between the amount of fecal matters collected from before and after set-ups of the bat repellent in terms of reproduced artificial light, generated high pitch of sound. After the data analysis, it was found out that the developed unit was also proven effective as revealed by the decreasing amount of fecal matters during the experimentation with the presence of artificial light with generated high pitch of sound, it was found to be the best setups within the area to minimize bat exposures. Based on the summary of findings, it is concluded that the solar powered electronic controlled bat repellent system is considered as an effective device to repel bats as revealed by the comparison of weights of the collected fecal matter in the area before and after the use of device from different set-ups of criteria from reproduced artificial, generated high pitch of sound and the combined functions of reproduced artificial light, generated high pitch sound. With this, it is recommended that research institutions must support and provide some of the needs of the researchers in constructing and developing the device for better output production. Further research and development in other field of studies should attempt to improve the device and its weather proofing and emission performance. Also, new studies should test other emission types such as short ultrasonic pulses that also mimic insects. Finally, a feasibility study must be conducted in order to determine the market acceptance of the device.
