Problems solved by technology

In this way, there is a problem that in this structural system, either the photovoltaic gang blocks the vacuum tube, or the vacuum tube blocks the photovoltaic panel, so that we cannot flexibly switch between the maximum power generation state and the maximum heat generation state; and, Since the photovoltaic panel and the vacuum tube are still independent of each other, the power generation efficiency of the photovoltaic panel is still unavoidable, resulting in a greater degree of waste of solar energy
