"The patented solution for the PID problem"

ask a


What is the PID problem?


Potential Induced Degradation (PID) is well-known and feared by solar panel manufacturers the world over. Because of poor grounding, high voltages and inadequate shielding between individual solar cells, leakage occurs, which dramatically reduces the electricity yield of solar panels. In some cases, the loss can be as high as 80% and can already occur in the first two years after roof installation. PID also increases the fire hazard of PV systems.


Potential Induced Degradation (PID)

We found the solution!


Ilumen, a team of motivated energy consultants and engineers, can detect and solve the PID problem in an early stage, grace to the patented PID Box. Ilumen is the only company in the world to successfully reverse the accelerated degradation of solar panels. Ilumen places the PID Box between the inverter and the panels, enabling the deteriorating panels to once again perform at their highest capacity.

In the animal kingdom owls are

considered smart and focused

animals. They are active at night

just like our PIDbox. That's why we

chose an owl as our mascotte.



Fastest power recovery in the world because of patented technology!


Ilumen uses various techniques for testing the energy yield of your solar panels. By using the electroluminance test, we examine how the various cells are functioning within the solar panels.

TUV Rheinland

Independent accredited research lab Eliosys tested the new technology and confirmed the efficiency of the PID-BOX. They confirm a regeneration of infected solar panels of which they initially thought the panels could only be used for the trash bin..

98% recovery was witnessed by several independent test laboratories!

So how does it work?


The device is connected to the PV system’s power outlet, right between the panels and the inverter. At night, when the solar cells are inactive, the PID box reverses the direction of the current and rejuvenates the degenerated cells.
