Solar PV technology has seen the highest growth rate among all renewable energy resources in the last decade and a steep learning curve resulting in a significant reduction in the cost of key components such as solar modules. For example, in the last decade, the price of solar modules has reduced ten times. In such a scenario developing solar PV agricultural processing machines is a rewarding proposition, particularly in the geographic south, notably Africa has an added advantage in terms of total solar radiations received. The current project aims at exploiting this potential in Ghana for cassava processing as a case study crop. Processing cassava is a key to preserve and make it suitable for consumption. Estimates suggest that lack of access to rapid processing machinery at smallholder level results in significant food losses and wastages. To undertake the challenge of rapid cassava processing, the solution which the team is offering is based on the principle of ‘‘decentralised cassava processing by solar driven machinery’’. A directly coupled photovoltaic (PV) panel and a direct current (DC) motor run chipping, grating and milling will provide efficient and fast processing of freshly harvested roots into dehydrated cassava products.

在过去十年中，太阳能光伏技术是所有可再生能源中增长率最高的，学习曲线陡峭，导致太阳能组件等关键部件的成本大幅降低。例如，在过去的十年里，太阳能组件的价格下降了十倍。在这种情况下，开发太阳能光伏农业加工机是一个有益的提议，特别是在地理上的南部，特别是非洲在接收到的总太阳辐射方面具有额外的优势。目前的项目旨在利用加纳的这一潜力，将木薯加工作为个案研究作物。加工木薯是保存并使其适合食用的关键。估计表明，在小农一级无法获得快速加工机器，导致大量粮食损失和浪费。为了应对木薯快速加工的挑战，该团队提出的解决方案是基于“太阳能机械分散加工木薯”的原则。直接耦合的光伏(PV)电池板和直流(DC)电机运行削片、格栅和碾磨，可将新鲜收获的根茎高效、快速地加工成脱水木薯产品。
