Abstract
The performance of Groundnut oil as phase change material (PCM) for thermal energy storage (TES) was investigated using a Solar Box Cooker (SBC) exposed to Maiduguri weather condition; Temperature and energy generated by SBC were experimentally established. The result shows tremendous improvement in energy storage compared to SBCs without TES in existence within Maiduguri and environs. The measured temperature and energy generated by the PCM in the experiment were 137oC and 307KJ respectively, an adequate temperature and energy stored by the PCM for cooking during off-sunshine hours. First figure of merit (F1) and second figure of merit (F2) were deduced to be 0.13 and 0.4 with overall SBC efficiency (ɳ) of 32% qualifying the SBC to grade ‘A’ based onthe Bureau of Indian Standards (BIS)
