The present invention is related to a "solar hydroponic floating island" contains: a floating-island carrier, its side coming with a solar panel which is wired to the motor to drive water wheel for pumping water. When the sun shines on the solar panel, it helps the motor drive water wheel for pumping water, discharge the filtered water. Inside the carrier a filter tank helps draw the external wastewater to process for clean water. Above the carrier equipped with hydroponic floating board can grow hydroponic plants and absorb water eutrophication substances. Such solar panels, pumping motor, carrier, inner filtering tank, hydroponic floating board to be integrated for a floating island construction is the characteristics of this creation.本創作為有關一種「太陽能水耕浮島」其係包括:一座浮島式載體,其側面有一個太陽能板,由電線連接到馬達,帶動水輪排水,當陽光照在太陽能板上時,即可驅動馬達帶動水輪,排出過濾水,而載體中有過濾槽可引進外部的污水處理成清水,在載體上方有水耕浮板,可栽植水耕植物並可吸附水中優養的物質,而此種將太陽能板與排水馬達,及載體與內部的過濾槽及水耕浮板整合為一體成型的浮島式結構,為本創作之特徵。
