Abstract The idea of developing a solar hybrid banana dryer designed explicitly for South Pacific will be a significant step forward in addressing both environmental sustainability and economic efficiency in the region. This paper encompasses the design steps and calculations of a sophisticated drying system tailored to meet local conditions, assuming one hybrid dryer as an example. It features an array of components such as solar panels, batteries, solar collectors, an air filter, a heat exchanger, a drying chamber, electric heaters, forced ventilation, and a control unit. This paper details the various phases of the project, including design objectives, options, literature review findings, design selection processes, detailed design calculations, and forward-looking recommendations. This design procedure can serve as a guide and can be used by any person who is interested in designing a dryer to meet South Pacific economic and environmental needs. The primary aim was to create a low-cost, sustainable, portable dryer that is simple to construct and maintain and capable of upholding hygiene standards despite variable weather conditions. When designing the dryer all calculations were presented as a guide for anyone and banana was used as the model material to produce banana powder, but it can be used for crops like breadfruit, pineapple, tomatoes and cassava and whatever else can benefit. By adopting this innovative solution, south pacific can benefit from an environmentally friendly, economically viable method of banana drying, supporting local agriculture and contributing to sustainable development in the region.
