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 uses a solar mirror as a heliostat, and focuses multiple solar mirrors on a solar photovoltaic panel on a solar photovoltaic panel. Due to the characteristics of tower solar energy collection, it makes part of the solar mirror in the process of tracking solar energy. 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

Description

technical field [0001] The invention relates to the utilization of solar energy, in particular to the use of a point-focused solar mirror to realize solar energy collection, the use of solar point focus to realize the focus and tracking of solar photovoltaic panels, and to the focus and utilization of solar energy. Background technique [0002] The solar focused photovoltaic power generation system uses solar focused tracking technology to realize the focused utilization of solar energy. [0003] The existing solar focused photovoltaic technology is mainly to directly drive the solar panel and keep it perpendicular to the sunlight, which can increase or decrease the collection efficiency of solar energy. But this tracking technique is not a focus tracking technique. [0004] There are mainly two types of solar point focusing utilization technologies: tower type and butterfly type. The dish type system uses solar mirrors to focus on a solar energy utilization device. And th...
