METHOD OF PERFORMANCE SIMULATION OF A SOLAR ENERGY SYSTEM

摘要

A method for performance simulation of a solar energy system (1) situated at a predetermined location and comprising at least one solar absorber (3), said method comprising carrying out on at least one programmable computer the steps of: a) generating: - a mesh of sun positions in the sky for multiple locations, one of which is said predetermined location; - a geometric model of said solar energy system (1); - a geometric model of surfaces and objects external to said solar energy system which interact radiatively therewith; b) Mapping radiative interaction between said solar energy system (1) and said surfaces, with said objects, with the sun and with the sky at at least some of said sun positions to generate a set of system-solar geometric maps of geometry- dependent radiative interactions of said at least one solar absorber; c) for a predetermined time period of interest, generating a time-dependent series of maps of radiative interactions of said at least one solar absorber by correlating the position of the sun in the sky at predetermined times to said mesh of sun positions and extracting the corresponding radiative interactions from said system- solar geometric maps; and d) simulating the performance of said solar energy system (1) based on said time- dependent series of maps and on meteorological data generated for said predetermined location for said predetermined time period of interest.
