To obtain the most energy from solar radiation, the solar panel must be perpendicular to the sun's rays. The angle that the solar panel adjusts in a year corresponds to the change in the height of the sun at noon in Taiyuan during the year. is located between the Tropic of Cancer and the Arctic Circle. The height change of the sun at noon in the year is 46°52', so the adjustment range of the solar panel in the year is 46°52', and C. is correct.
So choose: C.
The flat plate solar collector is a device that uses energy from solar radiation for hot water supply.
The operating principle is mainly based on the following steps:
1. Absorb solar radiation: Flat solar collectors generally consist of one or more black heat-absorbing plates. Absorbs short-wave radiation from sunlight and converts it into energy thermic
2. Converts to thermal energy: After absorbing solar radiation, the heat absorbing plate will heat up quickly and heat the air or other heat transfer media. on its surface (like water or oil).
3. Heat transfer: The heated heat transfer fluid circulates inside the collector, transferring heat from the heat absorbing plate to the water storage tank, causing the water temperature to increase.
4. Storage and use: Heated water is stored in a water storage tank with good thermal insulation performance for domestic or commercial use.
Thanks to their high efficiency, stability and environmental protection, flat plate solar collectors have become one of the most widely used solar water heating systems. Through scientific and reasonable design and installation, users can enjoybenefit from an adequate supply of hot water in various climatic conditions.
