What Happened To Tesla's Solar Roof Tiles? - YouTube
Channel: CNBC
[7]
the house you see around you
[8]
are all solar houses i don't know if you
[10]
know that
[12]
did you notice
[16]
so then then why would you buy anything
[18]
else elon musk unveiled prototypes of
[21]
tesla's solar roof tiles
[23]
in october 2016. they came in four
[26]
styles that looked just like normal
[27]
roofing material
[28]
but were essentially miniaturized
[30]
versions of traditional solar panels
[33]
the roof tile reveal helped tesla
[35]
justify a 2.6 billion
[37]
acquisition of solar city and
[39]
represented musk's vision for what the
[41]
businesses could do together
[43]
it's been almost two years since then so
[46]
where are the tiles
[48]
we now have several hundred homes with a
[50]
solar roof
[51]
on them that's going well it takes a
[53]
while to just confirm that the soil roof
[55]
is gonna last
[56]
you know for 30 years and all the
[57]
details work out as of may this year
[59]
reuters reported that there are actually
[61]
only 12 tiled roofs connected to the
[63]
grid
[64]
all in northern california tesla
[66]
declined to give an updated figure
[68]
but later clarified that hundreds of
[71]
homes refers to roofs that are scheduled
[73]
for install
[74]
or are only partially installed tesla's
[77]
been accepting
[78]
thousand dollar deposits for the roof
[80]
tile since may 2017
[82]
but at that point the company wasn't
[83]
even close to mass producing them
[85]
it established a factory in buffalo new
[87]
york to make the tiles
[89]
but it's not running at full capacity
[90]
yet and in the company's most recent
[92]
annual shareholder meeting
[94]
musk blamed ongoing delays on a need for
[96]
more testing
[98]
there's only so much accelerated life
[99]
testing that you do on a roof
[101]
so um before we can deploy it to a large
[104]
number of
[105]
houses we need to make sure that if that
[107]
all elements of the roof are going to
[109]
last for
[110]
at least three decades but ideally sort
[112]
of half a century or more
[115]
solar tiles like large solar panels use
[118]
silicon solar cells to convert
[119]
sunlight into electricity but it turns
[122]
out this tech
[122]
is difficult to shrink and to
[124]
manufacture
[126]
it's a little bit like saying the early
[128]
iphone
[129]
screens which were real breakthroughs
[131]
were just smaller versions of your flat
[133]
screen on your wall
[134]
making things small actually changes
[137]
a lot of the way that technology will
[139]
work and that's been a big challenge
[141]
i think for tesla but certainly for the
[143]
whole industry overall to try and
[145]
miniaturize it in a way that keeps it
[147]
cost effective
[148]
and also gives it the very very reliable
[150]
performance that solar is known for
[154]
one of the customers with the tiles
[155]
already installed is san jose resident
[158]
and tesla model 3 owner tree winn
[160]
he pre-ordered as soon as possible and
[162]
the roof was installed earlier this year
[165]
i was actually extremely surprised i got
[166]
the call just because i you never know
[168]
with this stuff right
[169]
i thought there'd be extreme delays i
[171]
just didn't know how long it was going
[173]
to take
[173]
while traditional solar panels can be
[175]
installed in a day
[176]
it took a team of 10 to 15 workers two
[179]
weeks to install this roof
[181]
wynn asked them why his home was chosen
[183]
they said it was kind of proximity to
[185]
their headquarters so that they could do
[186]
quick troubleshooting i think the
[188]
simplicity of the house helps you can
[190]
see my
[190]
house it's a very simple roof layouts on
[193]
it like complicated roof so i think that
[194]
goes into account as well
[196]
tesla's customers are paying a premium
[198]
for the tile sleek look
[200]
wynn's roof cost him about a hundred
[202]
thousand dollars
[203]
though he did need to replace his roof
[204]
anyway i don't think this will ever pay
[206]
for itself honestly
[208]
for people that don't need a new roof
[210]
but want to install solar traditional
[212]
panels are
[213]
definitely cheaper people have often
[215]
said to me
[216]
do we need to find some great new
[219]
technology to
[220]
finally make solar work and i think the
[223]
answer is no the solar industry has won
[225]
in america we have made solar cost
[228]
effective in most of the country
[230]
but wynn is excited to be an early
[232]
adopter and see his energy bill decrease
[235]
traditionally in the summer my my power
[237]
bill is around 400
[238]
450 in the summer my last bill was only
[241]
40
[243]
ultimately tesla's goal is to make the
[245]
tiles a cost-effective option
[247]
partly by ensuring they're more durable
[249]
than other rooftops
[251]
tesla's promising 30 years of solar
[253]
power generation
[255]
i would expect these solar roofing tiles
[258]
in just a few years to be quite
[260]
reasonably priced
[262]
if they can get the market interest that
[264]
they're hoping for
[265]
experts anticipate a wave of new solar
[267]
installations within the next three to
[269]
five years
[270]
not just for homes for businesses for
[274]
new mini malls for all kinds of built
[277]
infrastructure where we can make solar
[280]
the go-to product it's not just a
[282]
roofing shingle anymore it's a
[284]
power plant on your roof tesla says
[287]
solar roof installations will scale up
[289]
later this year
[290]
and into 2019 it's
[293]
highly likely that great engineers and
[296]
incredible technologists and
[298]
a lot of those people might be at tesla
[300]
are going to be able to take this very
[302]
difficult challenge and engineer the
[304]
heck out of it and get us to that
[306]
cost parity we're not there yet
