Interesting development and another reason to preserve solar access and OR+Fed renewable energy tax credits. Steven Strong spoke in Eugene RE Building Integrated Photovoltaics (BIPVs).
I assumed these had not dropped in price enough yet because not seen much on homes; used more for commercial instalIs?  In mid 80s Japan was developing a solar electric producing roof but not much news in recent decades. 

If the military had asserted the same muscle pushing for solar electric cell development as they had in their earlier thrust to replace vacuum tubes with transistors, photovoltaics would have been greatly reduced in price earlier according to The Dawning of Solar Cells by Institute for Local Self Reliance 1975. Decentralized renewables aka appropriate tech, what happened?

If installing PVs on roof or solar electric roof or walls, consider electromagnetic field issues and be discerning selecting inverters. Some persons more sensitive than others to fields. Educate consumer. Beats nukes
