Unisolar Efficiency by Bdosborn, on Flickr
Yes, Unisolar is more efficient at lower light levels. Unfortunately, efficiency decrease with increased irradiance so you actually have decreased unit output on sunny days. This doesn't address partial shading, angle to the sun or high heat conditions but I don't see much of a reason to go with Unisolar based on low light performance. The typical poly and mono panel is still going to outperform the unisolar, watt for watt, in low light conditions at STP.
