Power consumption is needed for operation in protected cultivation and is considered one of major production costs. For the purposes of costs down, energy saving and carbon reduction, development and application of renewable energy is one way leading toward the goals. The objectives of this study are to systemize as well as optimize the power supporting and managing system by using renewable energy (wind power and solar energy) so as to provide energy required for crop production and environmental control under structure in an efficient way. The system uses renewable energy as the major power source with Metro Power as supplement. The maximum capacity reaches up to 72 kWh with new type of lead-acid batteries . It can further be powered up to 220 kWh by replacing with new type of lithium iron batteries. Such a system can provide power/energy required for crop production in the field or under protected cultivation. It can also be used for power supply in remote area and marginal farm land. It is a research result of a cooperative research project among Taiwan Agricultural Research Institute, National Chung-Shan Institute of Science and Technology, and KTCOM Company.
