Even if the solar panel only reflects 1% of the light, the reflection of the sun would still be blindingly bright.

Re: "Even if the solar panel only reflects 1% of the light, the reflection of the sun would still be blindingly bright."

http://en.wikipedia.org/wiki/Albedo suggests otherwise.

4% is equivalent to Black Asphalt (basically the least reflective common surface they could find).

I'm a bit late, but you are mixing up diffuse reflection with specular reflection. The problem with solar panels is that they are practically mirrors.

Welding filter shade 5 lets through more light than that.

Typical sunglasses absorb 90% of light. Therefore two sunglasses on top another would absorb 99% and let 1% through. Is the remaining light enough to blind you when looking directly at the sun? I assumed yes, but I might be wrong. I'll have to find a second pair of shades to test.

Can you look directly at the sun with a Welding Filter shade 5?

Not continuously for hours, that takes about 14 or 15. But it isn't dazzling.
