Quote from: MountainDon on December 01, 2016, 11:22:29 PMI think that needs some more checking into. I believe the comparison to "regular" roofing was not to our nearly ubiquitous asphalt shingles but to more expensive tile roofs which the tesla solar roof looks like. Tesla pictures 4 types and all appear lsimilar in appearance to 4 different tile or slate roofs. Don't believe the $$ comparison is to ashphalt shingles until you see the actual product pricing and what instakllation requirements are. Just my skepticism showing through....
Quote from: Dave Sparks on December 08, 2016, 12:29:16 PMThe whole thought of connecting all those very low voltage panels in series is not something anyone living offgrid would want to do no matter how the connection is made. If you live on the grid it is nothing but money that you are risking with schemes like that. They say the connection method is easy and it will last..... Offgrid in some of the places I go there are very few people to help you and so the owner must make serviceable and intelligent choices. It is just too easy now to use (10) 45V solar panels in series and have zero problems for 30+ years.Imagine having strings with 80+ panels in series Imagine having to find the bad panel?When the fire people rate that kind of roof and it gets tested over time by early adopters, and the loss of efficiency of not having cool air under the panel, I might think about it for a barn roof offgrid. Certainly not the roof of an offgrid home. These solar tiles have been around(other companies) for 10 years now and none of them have been good for a typical home. Maybe someone will do this right because it does make sense for grid-tied solar, I just would not hold my breath!
