The invention provides a solar dustbin. The solar dustbin comprises a dustbin body and a solar photovoltaic module arranged at the top of the dustbin body. The dustbin body is internally provided with a storage battery connected with the solar photovoltaic module. One side of the dustbin body is provided with a rapid charging module which is connected with the storage battery. A garbage throwing opening is formed in the upper portion of the left side surface of the dustbin body. A garbage cleaning opening is formed in the lower portion of the right side surface of the dustbin body. A garbage cleaning door which can be opened or closed is arranged at the garbage cleaning opening. The garbage throwing opening is provided with an anti-overflow structure used for preventing garbage in the dustbin body from overflowing. The middle of the dustbin body is provided with a compressing mechanism used for compressing the garbage. The bottom of the dustbin body is provided with a cleaning mechanism through which the compressed garbage can be conveniently discharged out of the garbage cleaning opening. Charging can be conducted through solar power generation; moreover, the garbage can be compressed, so that the using space of the dustbin is expanded; and in addition, cleaning of the compressed garbage in the dustbin is facilitated.
