Small defects in the solar photovoltaic (PV) cells comprising each panel decreases the efficiency with which they convert sunlight into usable electricity or lead to premature failure. These defects can impose a significant cost in lost power generation over the panel''s operational lifespan, making it imperative to reject cells with even small defects before final assembly.
