Problems solved by technology

However, this type of tracking system has high cost, high energy consumption, and has certain limitations. It does not have functions such as snow protection and rainwater cleaning components, especially in severe weather (such as strong wind, rain, snow, etc.) and environmental conditions. Under severe weather conditions, the automatic tracking control cannot be effectively performed, and the solar array may even be damaged due to the untimely response of the tracking system under severe weather conditions; in addition, the conventional tracking system cannot monitor the tracking control effect of the solar array in time and automatically identify the failure of the solar array and shelters, to a certain extent, affect the utilization efficiency of solar energy and limit the promotion and application of solar tracking systems
