Increase your solar panels efficiency

Ilumen's PIDbox

Potential Induced Degradation (PID) occurs on all photovoltaic panels, often without the owner of the installation being aware of it.

Because of PID, the solar panels degrade faster and therefore they don’t achieve the expected return in 20 years. The degradation process occurs after 2 or 3 years and after this period it will proceed fast.

Our PIDbox regenerates solar panels affected by Potential Induced Degradation and prevents them from PID in the future. This way you can achieve the maximum potential of your solar panels.

Ilumen: the solar panel expert

Ilumen is a high end product developer and manufacturer with an own R&D department.

Dedicated engineers work daily to develop and create products to monitor your PV system, to help increase the yield and to ease up the maintenance process.

Ilumen is most famous for its patented PIDbox which increases the yield of PV systems.


Increase the efficiency of your solar panels today.


Frequently asked questions

“How do I know if my solar panels are already degraded?”

“Can you guarantee that the PIDbox does not harm my solar panels and inverter?”

“If my solar panels are still new, is buying a PIDbox still useful?”

“What is the difference between solar panels produced before and after 2008?”

“My installer claims that my solar panels are not PID sensitive, is this correct?”
