The method can be used to directly maximize the efficiency of photovoltaic power station. The proposed sensor composed of a micro controller for a photovoltaic cell ,a temperature sensor and the micro-controller is a low cost. Preliminary estimates indicate that the proposed sensor is of low cost ,so the device is a good substitute for large-scale deployment of photovoltaic power station. And the proposed method is validated by the experimental prototype ,the results show compared with commercial devices ,sensor designed in this paper can more accurately track the solar irradiance in the photovoltaic power station.
