Hainan Island is located in the south of the Tropic of Cancer, with a high sun angle all year round. The sun is located at the zenith twice in summer, and the altitude angle of the sun at noon is 84 45 ′ ~ 86 45 ′. Even on the winter solstice, the noon sun altitude angle is 46 05 ′ ~ 48 05 ′.

The annual total solar radiation is 4600 ~ 5800 MJ/m2 and the annual sunshine hours 1793 ~ 2590 hours, which lays the foundation for the formation of tropical climate.
