4 Frequently Asked Questions about "How to distinguish photovoltaic panel renovation"

What is repowering a solar plant?

This is a special case of repowering, where the installed capacity of the solar plant remains unchanged, but the production of the existing PV system is maximized by replacing fixed mounting structures with dynamic trackers that constantly adjust the angle of the panels to align with the daily path of the sun.

Where can greenbuddies repower older photovoltaic installations?

Since 2017, when Greenbuddies was founded, we have been delivering repowering services for older photovoltaic installations across the EU. These projects are primarily based in Germany and Italy, but there is a high potential for achieving higher efficiency in older PV installations throughout Europe.

Can a panel be replaced after 10 years?

The threshold for what is normal degradation and what is abnormal has been set by the German Network Agency at 10% after 10 years of operation. Panel replacement is therefore possible under several conditions, the main ones being: The new panels must not have a higher total installed capacity than the original panels.

What are the construction advantages of repowering?

The main construction advantage of repowering is the fact that it is not necessary to do new AC, especially the HV part.
