During the control of an active sun tracking solar system i.e. solar power plant ensuring own solar tracking strategy, control signals created in relation to the daily or intraday schedule of the solar power plant by specifying the power of 15-minute resolution, the current power of the solar power plant, the current values and maximum deviations of the azimuth angles and / or inclination angles of the sun tracking systems and the current Sun position data of the local location. If the current output of the solar power plant exceeds the threshold value of 103% of the current value of the schedule, the electricity production of the solar power plant is controlled in accordance with predetermined control parameters by influencing the azimuth angles and / or inclination angles of the sun tracking system of the solar power plant by the obtained control signals and temporarily disabling the solar power plant's own solar tracking strategy, thereby a control strategy ensuring more accurate schedule keeping is implemented.  The subject of the invention is also a switching arrangement implementing the method.

The active solar hot air collector is a hot air heat collecting device used for collecting solar heat energy to generate hot air and an active hot air supply device through a photovoltaic power generation direct-drive pipeline fan. Sunlight enters the heat collection box through the high-transmittance panel, the inner spiral heat collection black pipe rapidly converts light energy into heat energy, cold air in a space needing to be heated enters the heat collection box from the air inlet through the pipeline, and heat is rapidly taken away through the interior of the inner spiral heat collection black pipe. And the solar power generation panel (12v) generates power and directly drives the mute pipeline fan (12v) to quickly send hot air into a space needing to be heated through the air outlet through the fan work.
