- Abstract
Solar space heating presents a sustainable solution for maintaining indoor thermal comfort by utilizing solar thermal energy. This technology is broadly categorized into active systems, which use fluid-based solar collectors and distribution mechanisms, and passive systems, which rely on architectural features to naturally capture and retain solar heat. The present study focuses on an active solar space heating system that integrates heat pipe-based evacuated tube collectors (ETCs) with a paraffin-based thermal energy storage (TES) unit to enable nighttime space heating in remote, cold regions. The system architecture comprises three key components: the solar collector unit, thermal energy storage unit, and space heater. Field implementation demonstrated an energy storage capacity of approximately 16 kWh under an average Global Horizontal Irradiance (GHI) of 2.4 kWh/m2, effectively maintaining consistent indoor temperatures throughout the night. The simplicity of installation, minimal maintenance requirements, and reliable performance under low solar input conditions underscore the system’s suitability for off-grid applications in regions such as Leh. The results affirm the viability of this integrated solar thermal system as an efficient, cost-effective solution for domestic space heating in sun-rich, high-altitude cold climates.
