When discussing the logistics and take-back of solar installations, the system must not be viewed in isolation. As we have seen in the field of reverse logistics, transport and safety requirements become significantly more stringent as soon as a storage system comes into play. As photovoltaics and battery storage are increasingly connected today ...

A trade-in programme sounds profitable in theory, but its commercial success depends entirely on how it is implemented behind the scenes. As noted in the previous instalment of our series, it is not enough simply to take back old modules; they must be handled, sorted and transported without damage. This is where many solar companies encounter a ...

The concept has long been established: old devices are returned, the customer receives a credit note and, at the same time, chooses a new product. Similar concepts can now be found in smartphones, power tools, batteries and many other product groups. As highlighted in the first part of our series, a massive wave of refurbishment is also set to ...

The 2030 Refurbishment Wave: Why millions of solar panels will soon be replaced– and what opportunities this presents
On 10 , Jul 2026 | In | By Mona-Fee Kienle
The energy transition is often associated with the expansion of new photovoltaic systems. However, a less widely discussed development is becoming increasingly significant: the first major generation of solar installations is reaching the end of its technical and economic lifespan. Between 2005 and 2012, millions of photovoltaic modules were ...
