Abstract

Indonesia is a tropical country, thus making Indonesia has two seasons namely the rainy season and the dry season. Utilization of nature as electrical energy in the dry season is utilized by utilizing solar heat as energy stored during the day and used or used as electricity at night. However, in the rainy season there is no utilization of energy that can be utilized or used as electrical energy. This case for the researchers intend to utilize the energy generated from the rainwater pressure that descends from the sky as compressed energy on the piezoelectric. The objective of the study was to determine the optimal conditions of the initial testing of the solar-cell part of the hybrid model. The research method used is experimental experiment on solar cell with angle and time variation to determine current, voltage and power. Results obtained by the amount of angle, time, current and voltage generated from the solar cell to be used in the hybrid model: effective time and angle that is at 12:00 Clock and 180o, with a voltage (V) of 4.75 V, current (A) of 8.5 mA and power of 0.018921 W.
