Solar-powered greenhouses can utilize renewable solar energy to provide the greenhouse with power and maintain a comfortable environment for plant growth. Even if the weather outside the greenhouse is less than ideal for plant growth, a solar greenhouse’s controlled internal environment can be tailored explicitly for successful growth.
The results reveal that the system is able to store 331.9 GJ energy in non-heating season, and 208.9 GJ of this energy is successfully utilized in the greenhouse space heating. The electrical COP of the entire system is calculated to be 8.7, which is even better than conventional heat pump heating system.
The proposed TES system utilized 4,970 m 3 of the underground soil to store the thermal energy collected by a 500 m 2 solar collector through U-tube heat exchangers ( Fig. 19 ). The stored thermal energy was delivered to the greenhouse during heating seasons through the heat exchange pipes located on the plant’s shelves and the bare soil.
The greenhouse heating subsystem is capillary radiators. Through the design and operation parameters illustrated in Table 10, it is observed that 92.8% of the thermal energy is dissipated into the ground water tank with an annual energy loss of 12.7%. Fig. 19 shows a comparison of soil temperature with and without heat storage.
Solar energy can power various applications, from heating and cooling systems to lights and even machinery. In your greenhouse, you can use the energy you generate to run fans for ventilation, pumps for water circulation, or any other equipment necessary for optimal plant growth. How Is Solar Energy Used in Greenhouses?
They used an energy balance method considering the soil heat storage with a contribution share of 13–19% for heating load requirements. From the results, it was found that the air mass flux of 0.012 kg/s.m 2 can culminate in nearly 84% of the diurnal energy requirement of the greenhouse to maintain the indoor air temperature at 18 °C.
