A thermal rock storage bed was also integrated into the cabinet in order to collect heat during sunlight exposure and subsequently dissipate heat at night, during cloud cover, or in inclement weather. Specific design parameters were determined from a modified series of thermodynamic calculations originally proposed by Ampratwum (1998). This adapted approach took into account a variety of factors including the physical properties of mangoes, the local production capabilities of small Haitian villages, the characteristics of previously reported solar systems in literature and Haitian environmental conditions.
