The invention discloses a solar energy resource monitoring system based on Beidou satellite system. The monitoring system comprises a power analysis module, which is connected with solar cell panels by a load; a temperature sensor, a humidity sensor, a solar energy radiometer, an acquisition device, and a system server. The solar energy resource monitoring system is advantageous in that by adopting the Beidou short message communication technology, the solar energy resource monitoring information can be transmitted, and therefore the solar energy monitoring of the uninhabited remote areas or the mountainous areas without mobile signals can be realized; the system can be used to measure the capability of converting the solar energy into the electric energy under the actual condition, and during the long-term operation, the changes of the parameters of the solar cell panels such as the power generating condition and the attenuation rate can be acquired, and then the references can be provided for the construction of the photovoltaic power stations.
