Rooftop Solar PV Gets a New Face

Sanyo's bifacial PV

Sanyo's bifacial PV

Today in my blog “Brief Back” (written for True/Slant) I wrote about the implications of a story out of Canada that’s not getting much play in the States.

It’s about Sanyo’s “bifacial” solar PV, that can use solar radiation coming from in front or from behind it. Why do that? Because when it’s placed on roofs with 85% reflective coating, the array can produce 30% more electricity than the one-sided variety.

The details are more interesting than that might sound, so check it out at True/Slant.
