Method of Localizing Objects Temporarily Shadowing a PV System |
摘要 |
A method of localizing stationary objects causing temporary shadowing of light sensitive components of a PV system is disclosed. The method includes analyzing an electrical signal of the light sensitive components with regard to an occurrence of a shadowing event caused by the stationary object, and determining from a solar altitude associated with the shadowing event a direction of the stationary object causing the shadowing event. The analysis of the electrical signal takes into account a shadow movement of the object as a function of the solar altitude. A distance of the object is determined from this analysis. The results of the method may be used to determine an energy loss associated with the stationary object and may support a decision on removal of the object to improve efficiency of the PV system.
