The performance of design scheme affects space and light usage and investment benefits directly. In a given field, these parameters affect the system energy output interacting with each other. Therefore, Photovoltaic array optimization is necessary. In the present paper, a loss model used to calculate PV array shading loss was improved. Then, the design problem of photovoltaic solar fields for PV system to obtain maximum annual output energy and maximum gains was formulated based on the loss model. Afterward, the Particle Swarm Optimization algorithm was applied for the solution of the PV design problem and the design variables impact analysis. Lastly, the method was applied to actual roof PV system design and obtained satisfied results. The results verify the rationality of the design method and its practical value in engineering.
