Modulos String Ribbon de Sovello, cerca de cero degradación de las celulas en 25 años
Sovello String Ribbon Modules have a feature I did not realize before– near zero degradation of the cells over the 25 year warranty.
I am a bit stunned by the implications of this. When we say, all over this web site and in presentations, that it’s about ROI not cost per watt installed, we are completely serious. Now read what Sovello’s engineers wrote to one major US solar developer:
Here is the scientific explanation why Sovello modules demonstrate lower levels of degradation in the first three years of use than most of the polycrystalline modules made by our competitors, and why long-term yields usually either exceed forecasts or compare favorably to competitor products with similar (or even slightly better) nominal yields:
One of main culprits causing the degradation of ingot modules is the build-up of metal boron oxygen compounds as a result of diffusion. These compounds then form imperfections, which induce the recombination of free charge carriers. The oxygen here comes largely from crucibles used for the ingot installations.
STRING RIBBON uses other materials as crucibles (graphite), which do not add any oxygen to the melt. This means that Sovello wafers contain hardly any oxygen, significantly reducing the build-up of the aforementioned compounds in the STRING RIBBON material.
Sovello expects to substantiate these statements with figures by end of September, as they are currently getting this statement independently verified.
