? Solar greenhouses rely mainly on the construction of natural warm and night to maintain the indoor temperature insulation equipment. Solar radiation is to maintain the greenhouse temperature or sunlight to keep the heat balance of the most important energy source, with obvious high efficiency, low cost. ? Solar greenhouse construction must have good lighting roof, to maximize through the strong sunlight, heat and heat storage capacity, can minimize greenhouse heat, strong greenhouse effect, greenhouse length, width, ridge height and after high walls, front and rear sloping roof sloping roof and other specifications, dimensions and greenhouse scale should be appropriate. ?
