Problems solved by technology

[0002] At present, the existing intensive and large-scale devices need various links such as power transmission and transmission to reach the power consumption site. There are shortcomings of large overall investment, large loss in other links, and complicated process equipment.
Although the existing solar devices for solar orbit (trajectory) tracking overcome the shortcomings of solar position tracking, they have the disadvantages of large equipment space occupation, large power consumption in the tracking process, low total power generation efficiency, and complicated tracking control equipment and methods.
The solar device and method for solar position tracking have the disadvantages of being unable to track the control system in cloudy and cloudy days, large power consumption during the tracking process, and tracking failure and damage to equipment.
Existing solar energy equipment also has the disadvantage of either being able to generate electricity (such as static photovoltaic power generation devices) but not heating, or having the disadvantage of being able to supply heat but not generating electricity (such as fixed solar water heaters), and the total energy efficiency of sunlight utilization is low. shortcoming
