That's because they are cheaper and many like you believe they are less efficient in snow and cold when in fact they are more efficient in those situations.

Perhaps if you mount them flat on the roof. But not in the tubes in the comparison I showed or any steeper installation. Here is a plot from that system during the Nor'easter on December 18 and 19, 2009. Note that only the flat panel production goes to zero during the storm, but the tubes do not go to zero because the snow does not block the light.
Note again this test is from where you live. In the coldest months, the tube systems are 15% to 25% more efficient per unit area, including when there is massive snowfall.

This demonstrates how inefficient they are. Better not to accumulate the snow in the first place.

Yep, as I noted previously.
