In the third week of internship in Kauai, We went to interview with several local farmer to understand their situation and opinion in using of energy. Normally, the local farmers live next to their farms. They usually use electricity to power their agricultural needs such as the lights, irritation, or mower. They prefer to install the rooftop solar panel. After they install the solar panel, the first challenge they face is the geckos. The geckos like to bite the inverter, which cause serious damage for them. Although the inverters usually have warranty, solar power is main energy source for the local farmers in their warehouse. The interviewing with the local farmers benefit me a lot for my research project. It make me to totally understand every situation the local farmers face.
