Abstract The energy, exergy, economic analysis and optimization with the objective functions of energy efficiency, exergy efficiency, VAR cooling output, desalination output and total output of the polygeneration hybrid solar and biomass system are investigated. The optimization using the objective functions, constraints and the decision variables is carried out utilizing genetic algorithm in EES software for polygeneration hybrid solar and biomass system. In this paper, the optimized values of energy efficiency, exergy efficiency, VAR cooling output, desalination output and total output of the polygeneration system are achieved to 49.85%, 20.94%, 7278 kW, 4405 kW and 14,606 kW respectively. The payback period of polygeneration hybrid solar biomass system is 1.5 years at the electricity tariff rate of ₹7.45/kWh which is less than of solar thermal and hybrid solar biomass power plant.
