As the solar energy is intermittent, it needs to be stored in clear days to use the energy stored for heating at night [1], [2]. Besides water and soil itself as the solar energy storage medium, 20–150 mm rocks are usually utilized to
Canakci et al. [33] developed Active Heat Storage (AHS) that accumulates solar energy in a water tank for heating Chinese Solar Greenhouses (CSGs) on cold nights. They developed a model to characterize heat transfer phenomena and to promote the behavior of the AHS system ( Fig. 17 ).
A solar-powered greenhouse is a structure that uses the sun''s energy to heat up and provide light and energy for plants and crops. There are different types of solar greenhouses, and each comes with its own strengths and weaknesses. Solar-powered greenhouses can utilize renewable solar energy to provide the greenhouse

Solar heating systems for greenhouses utilize solar panels to capture sunlight and generate heat, offering an eco-friendly and sustainable heating solution. Proper sizing and design of the solar heating system, along with selecting the right type of solar panels, are crucial for efficiency and effectiveness.
In order to overcome this problem, energy storage is an effective solution to use the solar heat collected in the daytime for space heating when is required. However, most agricultural applications are short-term (diurnal) storage [3], [4], [5], which can only deal with a small part of heating loads and may not be sufficient in consecutive
