Solar greenhouse, also known as energy-saving solar greenhouse or warm shed, is a type of greenhouse prevalent in northern China. It is a greenhouse that does not require heating indoors, relying solely on sunlight to maintain a certain temperature level inside, even during the cold season, to meet the basic growth needs of vegetable crops.

The solar greenhouse primarily utilizes simple facilities, taking full advantage of solar energy, and in cold regions, it typically does not require heating for vegetable cultivation during winter. The cultivation facilities for fresh vegetables, known as solar greenhouses, possess distinct characteristics. The structure of solar greenhouses varies across regions, and there are numerous classification methods. By wall material, there are rammed earth greenhouses, brick and stone structures, and composite structures. By rear slope length, there are long rear slope and short rear slope greenhouses; by front slope design, there are two-fold, arched, three-fold, and micro-arched styles. In terms of structure, there are bamboo and wood, steel and wood, reinforced concrete, all-steel, all-reinforced concrete, suspended cable, and hot-dip galvanized steel pipe assembly structures.

The single-slope plastic greenhouses, with insulated covers on the southern slope and protective walls on the east, west, and north sides, are collectively known as solar greenhouses. Their prototype is the single-slope glass greenhouse, which evolved into the early solar greenhouses by replacing the light-transmitting cover material with plastic film instead of glass. Solar greenhouses are characterized by low investment, good insulation, and energy savings, making them particularly suitable for use in economically underdeveloped rural areas across our country.
