Abstract
A novel solar photoelectric micro-power supply integrated with wireless sensor nodes is designed based on the technology of the optimal voltage control. The solar photoelectric micro-power supply is composed of four photovoltaic (PV) panels, which are placed on different sides of the solar photoelectric micro-power supply and have same open voltage. The output voltage of solar cells is controlled in range of optimal voltage (6.28 V-6.8 V) by using the technology of optimal voltage control. Thus, the structure of micro-power supply is optimized. The experimental results show that the output power of PV panels is increased by 49.2% compared with that of single PV panel placed on the top of micro-power supply. And the practical output power of PV panels reaches about 90% of its maximum output power.
