Solar energy as a renewable energy it has an inexhaustible and clean and safe and so on, so have a broad application prospects, photovoltaic power generation technology is more and more attention, with the PV module continue to lower prices and photovoltaic technology, solar PV systems will gradually supplement the energy from the current transition to alternative energy. Convert solar energy into electric energy through the solar cell board, a microcontroller programming PWM wave to control the switch from the realization of output voltage and current changes, through the display circuit shows the output state and size, are implemented by ADC0809 acquisition and conversion of data and transmit it to the microcontroller judgment processing, so as to realize the intelligent output and control circuit.The BUCK circuit to charge the battery through the battery, the electricity generated by solar panels can be stored, and the use of singlechip microputer to control the working state of the whole system played a battery charging protection, over discharging protection, finally, through the USB interface will be stable DC power supply mobile phone. In addition, designs for potted tree to ensure that the solar panel lighting adequate. The LED light, the charging process of LED, system design has been through the plete pressure protection, avoid excessive battery charging and damage, and the charger adopts modular structure and USB interface, the mobile phone, charging MP3, cameras and other digital products. When the light is not strong enough, the indicator light does not shine, the battery for mobile phone charging, light is strong enough, the indicator lights, solar panels to power, also can charge the rechargeable battery. Software design adopts module design method, divided into the main part of the program, digital tube display module, AD conversion module generating module with PWM pulse width signal.
