Hainan Island is located in the tropical north, is a tropical monsoon climate, climate resources are abundant. Coastal hours of sunshine in 2069-2750 hours, the annual solar radiation energy of 123-141 kcal / cm ~ 2, is very conducive to the development of the sun industry and the research and utilization of solar energy. The average annual coastal temperature 23.4-25.4 ℃, ≥ 10 ℃ annual accumulated temperature up to 8562-9255 ℃. winter
