Throughout a PV system lifetime, it is often necessary to replace modules
Nearly all types of solar photovoltaic cells and technologies have developed dramatically, especially in the past 5 years. Here, we critically compare the different types of photovoltaic
We evaluate a PV system operating strategy that anticipates periodic replacement of all modules. Shorter-lived modules are later replaced with higher-performing, longer-lived modules, leading in many cases to a competitive levelized cost of electricity (LCOE).

The module replacement strategy demonstrates the possibility of commercialization for PV modules with limited lifetimes. Given the considerable progress for module efficiency, lifetime, and cost reduction, it is necessary to consider and comprehensively evaluate these variables to check the feasibility of module replacement in the future PV market.
Usually power and efficiency of the assembled photovoltaic modules do not match those of the initial cells. The ratio of the final module efficiency (or power) and the initial cell efficiency (or power) is called cell-to-module (CTM) ratio and represents an indicator for the performance-tuning of the photovoltaic device.
As for large-scale solar, module replacement remains the most competitive option. Repairing and reusing a solar module that is not complying with its expected lifetime provides for more environmental benefits than replacing the underperforming unit with a new and more performant PV module.
Module replacement can thus accelerate the market introduction and decarbonization impact of emerging PV technologies that have achieved a competitive module efficiency (≥20%), cost (≤$0.30/W), and lifetime (≥10 years) and have the potential to improve further on all three metrics but lack decades-long field deployment experience.
Module replacement may affect the bankability of a PV system, especially before replacement strategies are widely adopted. The use of new technologies (e.g., less reliable or less proven modules) or operational strategies (e.g., module replacement) may increase financing (discount) rates.
