Abstract: The invention relates to a solar thermal energy storage system that efficiently collects, stores, and supplies heat energy from the sun. The system includes: • A solar collector that captures sunlight and converts it into heat. • A thermal energy storage unit that stores the collected heat. • A nano-enhanced phase change material (NePCM) made from erythritol combined with special nanoparticles. • A heat transfer system for moving heat into and out of storage. • A thermal insulation arrangement to reduce heat loss. • A control and monitoring unit to manage system operation. The solar collector absorbs solar energy and transfers the heat to the storage unit containing the NePCM composite. The added nanoparticles improve the material's performance by lowering its melting temperature below 118°C, increasing thermal conductivity, and improving the rate of heat transfer. During periods of sunlight, the storage unit absorbs and stores thermal energy through a phase- change process. When sunlight is unavailable or limited, the stored heat is released in a controlled and nearly constant manner. The control unit manages the charging and discharging processes to ensure stable heat output and efficient operation. The method involves collecting solar heat, transferring it to the nano-enhanced phase change material, storing the energy during the phase transition, and releasing the stored heat when needed. By separating energy collection from energy use, the system provides a continuous and reliable heat supply even when solar radiation is intermittent. The invention offers improved heat storage capacity, enhanced thermal conductivity, energy efficiency, and cost-effective operation. It can be used in applications such as solar cooking, industrial heating, space heating, and other thermal energy systems.
