Who would have thought a layer of glass would substantially reduce insolation?

Not to say that it's a bad idea, you just have to overbuild the capacity. Pretty cool, imo.
I tested the change in output before I went ahead. It was not measurable with my voltmeter. The reason is that there is no air between the gelcoat and the solar cell. If there had been, it would have created specular reflection and a loss. However, the addition of too much blue pearl did lower the output a bit, I have yet to measure how much.
