According to introducing, in our province, the average annual sunshine duration for round hours, western coastal most as many as 26.5 hours. Illumination long, high strength, sunshine penetrability is strong, the solar energy resources. But now the hainan for solar energy utilization, especially in the construction sector use is at a low.
With the use of solar energy in building the most common way --
solar water heater, for example, relevant data shows, the solar energy water heater family popularization about 8%, yunnan, zhejiang, jiangsu, the prevalence rate of more than 20%, but in our province is less than 3%.
"This is a very regret of digital, although hainan provincial party committee and government in recent years attaches great importance to the development and utilization of solar energy, the introduction of a lot of enterprise development, but in building use but little, large-scale application has been slow development, therefore, the application of solar energy in hainan also has the very big space." Hainan renewable energy association secretary-general FanYiMin said.
To this, China building material federation ecological building materials branch secretary JiZhiJiang also think, hainan has many and good new energy sources, including solar energy, wind energy and so on, if fully exploit, and applied it to the building, so not only can achieve maximum energy saving effect, but also more environmentally friendly.
