Wind and light are inexhaustible renewable energy for human. Due to the needs to the environment and the shortage of traditional energy, and support from the government of the industrial policy, wind turbines and photovoltaic energy application get popularity, the system cost greatly reduced, and the configuration is more stable. Since there is abundant sunshine during the daytime but may small wind, and there is no sunshine in the night but may be strong wind, the wind and solar energy have strong complementarities. It has the advantages of solar energy and wind energy products, and make up for the insufficient when wind or photoelectric independent application. It is the perfect combination of the new energy comprehensive development and utilization.
