Green Vitality under Photovoltaic Panels

Husbandry and agriculture coexistence: Technology and value innovation with technology democracy as the core of action
National Cheng Kung University
After Typhoon Morakot hit Taiwan, the Pingtung County Government has promoted the project of “Photovoltaic Farming to Reserve Water” to encourage the farmlands and fish farms on the field unfavorable for farming to introduce photovoltaic panels so as to reduce land subsidence caused by groundwater overdraft. However, in addition to landscape deserting, the residents must change their original ways of making a living if the land is only used for installing photovoltaic panels.
With the concept of “Saving Water Resources and Increase Land Use Efficiency”, Professor, Chang, Jo-Shu, has led NCKU Team to design an algae cultivation platform under the photovoltaic panels. Algae can be used as feed to reduce the feeding cost, enhance harvest amount and purify the water so that water replacement is not required during the cultivation process so that water consumption can be reduced. Meanwhile, the local animal farmers also participated in the experiment. They have designed a farming tank built by HDPE and metallic tubes. This new tank can be seen as the implementation of local knowledge. With fine-tuning in the future, they can connect with specialists from NCKU and build a cultivation plan suitable for local conditions.
Environmental sustainability is an important issue concerned contemporary. However, “all scientific and technological solutions are required to connect with practical social solutions, which is the core value of the project.” “Only when technologies can meet public needs and embed in the social, economic and culture network, there are opportunities to discover the true innovation brought by the connection,” said Associate Professor, Chien, I-Ming.
