Solar module cell replacement

Can a PV module be replaced?

While module replacement can be applied to any PV system regardless of size or location, we do not claim that replacement is always—or even often—economically favorable.

Can solar cells be remanufactured?

Here, the active components of the solar cell can potentially be washed off to directly re-use bulk materials with high environmental impact such as glass. When a combination of re-used, recycled, repaired, or replaced parts serves to manufacture a new product, the term remanufacturing can be used.

How long should PV modules be replaced?

The shortest optimal replacement period in our analysis is 8 years (for the highest initial degradation rates of over 3%/year)—far longer than the EPBT of all PV technologies. Thus, if a module replacement strategy can increase low-carbon energy generation by making PV more affordable, it is likely favorable from a CO 2 mitigation perspective.

Should solar module recycling be scaled up?

Scaling up module recycling is critical for realizing carbon mitigation benefits without substituting other environmental harm. For policymakers and industry players, module replacement presents an opportunity to maintain low costs while supporting the near-term deployment of high-potential PV technologies.
