The invention discloses an omnibearing integrated monitoring system for a photovoltaic panel. The system comprises the following specific steps: carrying out generated power monitoring on a photovoltaic power generation assembly; using a cleaning robot, a temperature sensor and a laser sensor to carry out cleanliness monitoring and timely cleaning on the photovoltaic panel; and receiving data transmitted by the sensor to carry out unified treatment through an operation platform of the photovoltaic panel. According to the method disclosed by the invention, the cleanliness of the photovoltaic panel is detected by using a laser reflection principle, and simultaneously, based on the temperature sensor array and the temperature distribution detection of the photovoltaic panel of the cleaning robot, the operation platform is integrally connected with a monitoring site through the connection of a wireless network. Based on this, the analytical statement of historical data of photovoltaic power generation and the benefit evaluation of operation measures such as the cleaning robot are realized.
