Did you know that there is an official measurement for a hairs breadth? Well, according to my conversion tables:
one hairs breadth = 100 microns (micrometers, millionths of a meter)
So the thickness of a regular silicon solar cell, at around 200 microns, or 2 hairs breadths, is pretty darn thin! And when you consider that the SunPower® back-contact cells that are used by Solara and Solbian are even thinner, at about 1.5 hairs breadth, and that these cells are essentially glass in nature, you will no doubt appreciate that they will need careful handling.
The SunPower® cells used in Solbian flexible panels are high grade cells that are purchased guaranteed free from physical defects, but careless handling in storage, shipping or on site, together with improper installation, can initiate cracks in the cells which will be invisible to the naked eye.
In the majority of applications these cracks will be comparatively harmless and may not cause any problems other than a small loss of power, but
