Abstract

Solar energy and photovoltaic (PV) was known as attractive solution as alternative power generation source that is sustainable. Despite of that, biggest limitation of solar energy is its avaibility. The reasons are the clouds and nightfall interrupt collection of energy, thus limit time and lack of efficient for solar to charge batteries during this situation. The purpose of this study is implementation of a solar energy using supercapacitor for power storage in application low power circuit devices. A supecapacitor is an energy storage device utilizes high surface area carbon to deliver much higher energy density than conventional capacitors. The supercapacitor balancing circuit use in this device as charging circuit and balance the voltage between two supercapacitors and thus protect them from overvoltage. In this study solar device performs maximum power solar energy collection from balancing circuit with under various light conditions, with high efficiency and low energy cost without using mechanical solar tracker. Much attention has been given to identify the power use in circuit component. The result shows that system maintains averagely 10V to charge the battery in any weather condition except nightfall. This system achieves low power consumption which maintained operation efficiency and reduce cost operation of solar energy.
