Revamping: The Smart Way to Upgrade Your Solar Park
The gradual decline in module performance is a well-known issue. This phenomenon, known as solar module degradation, typically sees modules losing around 0.5 to over 1 percent of their efficiency each year. Consequently, after ten years, a solar park's nominal output can drop to less than 90 percent of the original value. As the solar industry matures, so does the need for ongoing maintenance and optimization of solar parks. One of the most effective strategies emerging globally is revamping — the process of replacing older, less efficient modules with newer, more powerful ones.

Adapting to local needs
By selecting the appropriate revamping model, solar park operators can effectively counteract module degradation, enhance performance, and ensure long-term sustainability. Each variant offers a strategic way to optimize existing infrastructure and adapt to changing market conditions.

Revamping light
In this model, all old modules are removed and replaced with new, generally more powerful ones. The number of new modules installed is sufficient to restore the original nominal capacity, ensuring compliance with the existing EEG compensation or other support schemes. This means that some of the tables will remain empty.

Revamping medium
Here, all old modules are also removed. However, in this model, all racks are fully equipped with new solar modules. The capacity that exceeds the original nominal output by a certain factor, must then be marketed outside of the EEG framework in Germany and Greece, either through a Power Purchase Agreement or directly on the electricity exchange.

Revamping heavy
This approach utilizes the EEG compensation in Greece and Germany for the existing nominal capacity, but beyond that, both the modules and the racks are completely replaced, maximizing the use of the park's area. Any capacity exceeding the original nominal output is also marketed outside the EEG.
Global success stories in solar farm revamping
In the past eight years, we have replaced about 725,000 modules in 18 solar parks. This corresponds to a capacity of around 120 megawatts. Here´s a glimpse of our recent projects:
