Good economic benefit good shape road landscape
The electrical energy can be produced by sun light in sunny day; the electrical energy can be produced by wind in cloudy-rainy day and at night. The more electrical energy can be produced by wind-solar complementation, so, the service power of expensive solar panel can be reduced greatly, the time light on can be delayed and also reach the lighting requirement of routine street light. At the same time, the beautiful, dynamic and unique scenery line is formed.
Advantage
Good economic benefit
The construction cost of supply power line for street light is very high when it is more than 3km from power point, because the street light can be supplied power with buried cable. With extension of kilometers, the boosting system also need be set up, so, for outer suburbs road, the cost of supply power line is very high, the consumption of electrical energy in supply power line is very high. While, the complementary street light of wind-solar do not need supply power line, has not consumption of electrical energy, and has remarkable economic benefit.
Good shape, road landscape
The windmill with good shape is in line along road and dancing accompanying with wind, which will be a beautiful scenery line.
