'Researchers from Spain found that semi-transparent PV systems are commercially viable only up to about 50% transparency, as higher transparency sharply reduces efficiency and increases system costs. Their analysis shows that declining power density, and not balance-of-system or financing factors, is the main driver of higher LCOE, even in high-irradiation regions.'
