OK, moving right along.
Now for the electrical side of things.
Thanks to the makers of this video for confirming that the maximum voltage of a string of 8 tiles is just 16 Volts.
This is entirely consistent with my earlier analysis http://teslabears.club/t/tesla-solar-two-shakes-short-of-a-shingle/124/3
Each tile of the triplet is a single 6 inch cell with an open circuit voltage of 0.6 Volts.
The string of 8 triplets complete with 16 pairs of connectors is roughly equivalent to a (nominal) 12 Volt 100 Watt panel.
This is the sort of panel that is used by campers or old hippies living in caravans but in the modern age of higher powered systems using MPPT regulators it is farcical.
Industry standard panels are at least 250 Watt and 40 Volt nominal voltage
The most common installations use 3 or 4 of those panels in series to form the string.
To equal this performance using Tesla roof tiles would use an absurd quantity of connectors that pose a risk of failure and the possibility of starting a fire.
