The invention provides optimized input and output power control solar power supply equipment. The equipment includes several optimized input and output power control solar power supply devices connected in parallel and suitable for being electrically connected with several solar panels. Each solar power supply device includes a switch circuit, a voltage conversion circuit, an output interface anda control unit. Each switch circuit has an output end and an input end which is used for receiving one input voltage and one input current of the corresponding solar panel, the corresponding voltage conversion circuit receives the input voltage and the input current and outputs an output voltage and an output current, and the corresponding control unit calculates an input power and an output powerand adjusts the conduction time and non-conduction time of the input end and the output end according to the value of the input power and the value of the output power respectively so as to obtain the optimal input power and
