A solar panel that takes that much space for a supposed 124w output is a joke.

Unisolar does use more sq inches of roof space per watt generated

they are also lighter, work over a larger spectrum of light, and very hard to damage,

you can not crack them or get water leaks from weather, hail, or being stepped on, they are shade tolerant, with bypass diodes on each cell,
partial shading does not stop them from producing power

the 64 & 68 watt panels are ideally suited for parallel operation and can be used with a PWM controller iF so desired

I didn't intend for this to be an argumentative discussion on whether these were good (your definition) solar panels or what kind of controller to use. To me, they are a good buy. I only wish to know if they can be trimmed to fit. If so, I can squeeze alot of watts flat on my roof which is what I want to do.

These panels from ebay are a real good deal and I'd like to be able to use them but....I only have 15'6" of straight line on the roof and they are 16'5". Can they be cut? I realize the watts & volts would be diminished a little.
