We unburden you and increase the yield of your customers!

Potential Induced Degradation (PID) is a well known and understood degradation process in solar modules.

In order to cope with this phenomenon iLumen developed the PIDbox,  which is a solution for PID that unburdens you by optimizing the return of the PV plants of your customers.

Furthermore, the PIDbox is a very interesting tool that keeps you in touch with your customers.

PID effect over de jaren heen

Potential Induced Degradation

Characteristic for PV installations is that they will underperform as a result of Potential Induced Degradation or PID.

PID occurs on all photovoltaic panels, often without the owner of the installation being aware of it, and implies accelerated efficiency losses. Due to high humidity and temperature differences, certain solar cells become inactive.

As a result, the solar panels degrade faster and therefore don’t achieve the expected return during their lifetime. The degradation process often occurs after 2 or 3 years and after this it will proceed fast.

Which PV modules suffer from PID?

Scientific research has shown that each solar panel suffers from PID. Especially PV systems that were installed after 2008, appeared to be very sensitive for PID. This conclusion is confirmed by independent research of Solar Tester, which shows that more than two thirds of solar panels of 10 years or younger is suffering from efficiency losses greater than 20%.

In 2008, it became impossible to ground the cable that runs from the solar panels to the inverter (negative pole). This resulted in larger tensions, and therefore in more leakage current to the earth.

Nevertheless, PV-systems installed before 2008 suffer from Potential Induced Degradation. So-called ‘PID-free’ solar panels do not exist!

Pidbox Mini indoor iLumen

Engineers of iLumen have developed a solution that regenerates and prevents from efficiency losses due to Potential Induced Degradation.

The solution is called PIDbox. This device increases the yield of solar modules and extends their lifespan. The patented PIDbox is the only PID solution on the market that operates completely independent of the inverter, so inverter warranty is never void.

Independent Research proves an average efficiency increase of 7,45% after a PIDbox is installed. The minimum efficiency increase equals 3%, the maximum increase almost 17%.
