Fuzzy logic controls have been used to develop intelligent control systems in greenhouses, leading to promote a comfortable microclimate for plant growth while saving energy and water resources. Solar energy is an effective solution to extend the use of these intelligent systems in isolated areas. In fact, this paper presents a practical solution based on the power-aware design for controlling the indoor environment of solar greenhouses. The system consists of feedback fuzzy logic controllers that log key field parameters using specific sensors and performs control actions for the environmental temperature, soil moisture, and relative humidity. With regard to the battery-coupled architecture of the solar system, the decision level is designed to consider the availability of operational resources before acting. Keeping in mind the constraint of low-cost, we propose a flexible design of an embedded system able to support remote management of the indoor environment key-parameters. The proposed control system was validated experimentally. The efficiency of the system was assessed by demonstrating significant energy and water savings as well as protection of solar system components from dry running issues
