The fact: Light acts on the materials and affects the yield form the crystalline silicon cells of photovoltaic modules, contributing to two types of degradation, the well-known LID and the mere recently discussed LeTID (Light and Elevated Temperature Induced Degradation).
The LID effect.
Well-known in the industry for more than 20 years, Light Induced Degradation (LID) is measurable from the first hours of exposure of solar panels to sunlight, due to traces of oxygen included in the molten silicon during the Czochralski process for creating silicon crystals, hence the silicon wafer.
Although the Lid effect is an unavoidable phenomenon, not all solar panels in the market are equally resistant to it. aleo modules have an average LID of only 0.6%, which is very low, and is a guarantee of the quality silicon used.
As a result of high quality, aleo guarantees 98% of the initial power (the one measured at the factory, in the end of production) for the first 2 years of operation of the module.
THE FACT: aleo modules offer the highest and longest guarantee in the industry.
THE ADVANTAGE: The PV-System owner jumps right into pole position, by way of minimizing losses, maximum solar energy production from day one.
The LeTID effect.
Contrary to the Lid effect, which has been studied for over 20 years, the Light and Elevated Temperature Induced Degradation (LeTID) phenomenon has only recently been discovered.
LeTID refers to a degradation effect caused by light and high temperatures that affect the panels' efficiency after years of operation. It may cause a significant power loss in systems installed in locations with high irradiation and high-temperatures.
aleo solar panels have a high resistance to the LeTID effect, with a maximum power loss of 1,52% vs the 5% maximum allowed standard.
