Abstract
The present invention relates to a maximum power point tracking circuit for a solar panel. In one embodiment, the circuit can include: a real-time power calculator that receives a real-time output voltage and a real-time output current of the solar panel, and generates a real-time power of the solar panel; a memory power generator coupled to the real-time power calculator, and that generates a memory power based on the real-time power; a comparing circuit that compares the real-time power against the memory power, where an output of the comparing circuit is configured to control a controlling signal for a solar power supply apparatus; and a reset circuit that receives the real-time output voltage of the solar panel, where an output of the reset circuit is configured to control the controlling signal.
