The invention provides an SOFC multi-combined supply system and method driven by solar energy and biogas. A heat storage tank of a groove type solar heat collector communicates with a first heat exchanger in an organic Rankine cycle module, so that a working medium in the heat storage tank heats a working medium in the organic Rankine cycle module; the first heat exchanger is communicated with a second heat exchanger in the anaerobic digestion module, so that the low-temperature working medium drives the anaerobic reaction tank, and the second heat exchanger is communicated with a liquid storage tank of the trough type solar heat collector; a CH4 storage tank of the anaerobic digestion module is communicated with a fuel compressor of the SOFC module, and a waste gas output pipeline of the SOFC module is communicated with a regenerative steam generator of the Kalina cycle module, so that waste gas of the SOFC module drives the Kalina cycle module to generate power; the PTSC is coupled with ORC, anaerobic diges
