Problems solved by technology

And the solar energy utilization equipment of existing dish technology moves with the change of the sunglasses, because the weight of large solar energy utilization equipment will increase the load, which is not conducive to tracking, so the existing dish technology needs to be improved
[0005] The tower system is an alkali metal power generation device that uses a solar mirror as a heliostat and focuses multiple solar reflectors on an alkali metal power generation device. The utilization time is only 4-6 hours. For example, the solar mirror on the east side of the tower is basically unusable in the morning, and can only be used after noon or afternoon, so the efficiency of solar energy collection is low. This technical solution can realize high-temperature collection, but Usually its size is large, not suitable for small or home systems
