As you know, solar power system is a power generation system that converts solar energy into electric energy. It consists of solar cell, power conversion device, inverter and battery.

In a solar cell, electrons and holes generated by a photon contained in light energy are shifted toward the n-type semiconductor due to the electric field generated at the pn junction, and holes move toward the p-type semiconductor, . One or more solar cells are connected in series and parallel (solar cell array) to generate DC electricity.

The power conversion apparatus is usually constituted by a DC / DC converter and performs a function of increasing or decreasing the DC output voltage of the solar cell array, which is changed due to the solar radiation amount, the temperature, or the surrounding environment, And the inverter is formed of a DC / AC converter to convert DC voltage to AC voltage.
