The most appropriate storage of solar energy in green house according to the technical,economic and environmrntal factors

Due to the limitation of water land and energy resources, prepared research aimed at finding the most suitable solar energy absorption system was designed for use in greenhouses so, the greenhouses were built an area 10m2 in Izeh city in Khuzestan province.
Common system of heating greenhouses in addition, four other systems including: solar water heater, water wall, stone bed and phase-change material. Each was implement in a greenhouse and the research was conducted during six months.
Technical factors including functional safety, useful life, reliability, ease of maintenance and repairs beside of economic and environmental factors have been investigated, finally, the method of Analytic Hierarchy process (AHP) was used to introduce the best system.
The result showed that the solar water heater system has had higher cost and energy absorption also lower average time to repair and phase-change material method has had the least failure frequency. The analytic hierarchy determined aquatic wall as the most appropriate system and thence the solar water heater. Although solar water heater consumes less fuel but it has more cost, lower sale services, failure frequency and repeating accident rate more than water wall. This method can be in the first place by reducing cost and improving after – sale services. In last place of the traditional method shows that it was not suitable and it’s use should be revised.
