As of 2012, the total area of solar greenhouse in China has reached 900,000 hectares, accounting for 33% of the total area of the country’s facilities. The rapid development of solar greenhouse has made great contributions to solving the supply of winter fresh vegetables in northern China and raising the income of farmers.
