Have fun,

I see an increase, too but not at that level. maybe 15 to 20% but never investigated beyond noticing that rather than the 9 amps I see in summer I am getting 10+ now in full sun but we get true cold here a lot.
I just smile and burn it up ;=>
Cheers.

Second, have a look at Poulek's concentrating traxle. He claims the mirrors increase output by up to 100%.

I have seen the same thing with my four pw-750 panels. Snow on the ground (reflected light) and cooler temps almost double the AH I get from the panels on a good day - I do have some shading later in the day. Now if I could see sunlight more than a couple days a month during the winter.....
I remember reading an article many years ago about an antarctic monitoring station. They mounted panels vertically. The reasoning was that the reflected light from the snow & ice boosted output, and the vertical orientation kept them from packing with snow.
