【正文】 was designed in accordance with the output characteristic of the solar panel. The pulse width modulated(PWM) wave was regulated the solar panel’s output can look for maximum power point constantly and make the solar panel output maximum power design can enhance efficiency about 20% and display output indicators of the solar is very convenient to use.
