Hi all!
Info regarding their solar cell efficiency:
http://www.scientificamerican.com/article.cfm?id=worlds-mightiest-solar-boat
"PlanetSolar also uses the highest efficiency mass-produced solar cells. Manufactured by SunPower Corp. for installation on the rooftops of homes and commercial buildings, these cells can convert 22 percent of the sun's energy into electricity, says Joern Juergens, director of components at SunPower. After installation on the ship, however, the cells' efficiency is reduced to 19 percent, because they must be covered in layers of plastic and transparent composites in order to make them immune to the corrosive effects of seawater and variable temperatures."
Also found in Planet Solar's logbook:
http://www.planetsolar.org/be-part-of-it/logbook.html
"While our solar panels love the sunshine, they do not like heat. This holds true for all photovoltaic cells. All 10°C bring about a loss of 3 percent of efficiency."
I also noticed that some of their solar panels are mounted on "slide-out":
