Retrofit Kit

A Hybrid solar upgrade application for everybody.


Compatible with the majority of the solar panels of the market


No aesthetic compromise


Upgrades the existing conventional solar panels to hybrid ones

Fegen has the uniqueness of being worldwide the only PVT manufacturer holding an internationally valid and recognized certificate, that gives the ability to safely combine whichever UL listed PV panel with Fegen RFK, resulting in a very rapid and toolless way, in a light, thin, very efficient and absolutely safe, PVT panel.

Besides, being this way globally the only product suitable for safely retrofitting PV installations to PVT ones, this certified integration surpasses the obstacle of the 10% electric power tolerance between certified and used PVT panel in installations, which practically results in either using electrically inefficient PVT panels in an installation, or making an installation itself non certified for safety, thus, not capable to be properly insured.

There is no aesthetic compromise, as the upgraded hybrid solar panels are identically looking with the conventional solar ones.
The hybrid panels are connected via tubes that are covered in such a way that looks of a homogeneous surface is ensured. In the boiler room, there is no extra space needed.
RetroFit has no geographical boundaries. Existing boiler room is indoor, so it is not exposed to extreme cold conditions that could freeze water. However, even in this case, as the closed liquid circuit of the hybrid panels is heated by the sun, it prevents freezing in most weather conditions, inside the panels and the running of all circuit.
