Unisolar solar panels are a little different than the other solar panel kids.
In fact, they aren't so much solar panels as thin-film solar laminates.
Unisolar is a world leader in thin-film technology and has developed a technology to reduce the materials cost in a solar cell.
Unisolar efficiency has also achieved world records for thin-film panels.
They have accomplished this through a "multi-junction" approach that lays different levels of amorphous cells on top of one another.
What are the benefits of this thin-film technology?
Easy to install
"Real world" efficient
Are you wondering about the difference between "thin-film" technology and a standard solar panel?
Well, here are the basics: Thin-film is cheaper but it is less efficient so you'll need to use more space to achieve the same output as traditional solar panels.
So, you say, if thin-film is less efficient why does Uni-solar tout their "real-world" efficiency? This is because thin-film technology performs better than a solar panel in cloudy or hot conditions. Depending on your climate, this could be a big advantage.
Thin-film technology is an exciting growth area in the solar world and Uni-Solar solar panels will be at the forefront of the movement.
Here are the specs on Uni-Solar products:

Now, onto the stats...
Rated Power at STC (Standard Test Conditions)
This will be the "advertised" wattage of the panel you're looking at (e.g. 180 watt or 205 watt).
Rated Power Tolerance (%) +/-5%
Rated Power Per Sq. Ft. (Watts) PVL-68 - 5.6
PVL-124 - 5.8
PVL-136 - 5.8
