A novel multigeneration system powered by hybrid solar-biogas energy was investigated to generate electricity via improved Brayton and Rankine cycles, produce hydrogen via a solid oxide electrolyzer, and provide domestic heat. The system was optimized using multi-objective optimization modeling after the parametric thermodynamic and economic evaluation. Explainable artificial intelligence and the Analytic Hierarchy Process were applied to an efficiency analysis technique for multi-objective optimization. According to the parametric analysis, energy and exergy efficiencies, power, hydrogen production, stored heat, and the net present value range between 17.55 and 42.75%, 17.41–39.78%, 570.04–733.58 kW, 0.053–0.239 kmol/s, and 9808.72–10140.16 MJ/day, 0.17–2.42 million US$, respectively. At the optimal solution, the overall energy and exergy efficiencies of the system were determined to be 41.96% and 39.08%, with 0.233 kmol/s of hydrogen and 697.91 kW of net power, and the net present value analysis was determined to be 2.35 million US$.
