摘要

Method of optimizing the repowering of photovoltaic solar plants through predictive and intelligent preventive maintenance. The invention is a method of optimizing the repowering of solar photovoltaic plants by taking advantage of intelligent preventive and predictive maintenance that detects the failures of modules or cells within the modules, aerial inspections by infrared thermography and/or by electroluminescence. In the method object of the invention, the defective modules detected are separated into groups of different types of failures: A - irreversible failure; B - reversible failure and C - partially reusable failure. The repowering consists in replacing the modules with type A failure with new, higher power modules, and regrouping them connected in series in the same branches (1). Modules with type B failure are repaired and replaced in their original location, and modules C either regroup into branches in series, or are replaced by new modules of higher power, which will also be connected in series in branches (one).
