After clicking the command, set the data to be displayed in the solar altitude angle in the right-click menu, and then click the object surface to mark the solar irradiation data and reference point / line / surface at the current time< br />
Plug in function: mark the solar irradiation data, including solar altitude angle, summer solstice, winter solstice, spring equinox, latitude, longitude, altitude and azimuth. You can also see the incidence angle, irradiation percentage, horizontal shadow angle and vertical shadow angle< br />
The "incident light" generated during annotation is presented as an auxiliary dotted line. Auxiliary points and a surface perpendicular to the incident light can be automatically generated at both ends. The auxiliary lines and auxiliary points can draw geometry and shadow surfaces related to the sun. The surface perpendicular to the incident light is helpful to determine the direction of drawing the solar panel< br />
This tool can be used in a wide range of energy-saving design. According to the relationship between solar height angle and shadow, it can be used to determine the orientation, building spacing and building height of houses in different seasons, calculate and design the installation angle of solar water heater and street lamp, and judge the distribution of mountain natural belt on sunny and shady slopes
