3. INTRODUCTION
• Tesla roof panels are unlike traditional solar panels in that every tile
contains one solar cell. They not only look like, and function as,
conventional roofing materials, such as terracotta, slate, or asphalt, they
also produce electricity.
• The Solar Roof line of products is unique among other solar options
because it doesn’t resemble a typical solar installation. Every solar cell is
embedded invisibly within every glass tile. The tiles are then installed
like traditional roofing shingles or tiles. If you didn't know the roof was a
Tesla product, you’d probably never realize it.

4. • Unlike other solar products, Tesla systems are designed to collect up to 98
percent of the solar energy that traditional arrays collect. The unique type
of louvered glass tile works in much the same way as window blinds by
reflecting sunlight to appear opaque while still absorbing the rays of the
sun.
• The electricity generated by the solar roof tiles is then used to power your
house and possibly also to charge the Powerwall battery if you choose to
store your solar energy for later use. Tesla tiles can be installed on new
construction, as part of a re-roofing project.

5. HISTORY
The technology behind the first solar roof tiles (also called solar shingles)
was developed in the 1970s. Since then, several companies have attempted
to produce a solar medium that would look and function like a traditional
roofing system and also replace traditional solar panel add-ons.
While building integrated photovoltaic (known as BIPV) options aren’t a
new concept, the Tesla’s Solar Roof products have taken aesthetics to a
whole new level - just as Tesla Motors have done with their electric cars.

6. MATERIALS USES IN SOLAR
ROOF TILES
• The new solar roof will be offered in four designs: Tuscan glass tile,
slate glass tile, textured glass tile, and smooth glass tile.
• Musk demonstrated the strength of his new roofing product by testing
heavyweights on three common roof shingles as well as his own. Sure
enough, the Tesla roof was the only one that could withstand the
weight and pressure. “It’s made of quartz,” explained Musk. “It has a
quasi-infinite lifetime.” Tesla is now stating on its website that the roof
tiles used in its solar roof installations have an “infinite warranty”
because of the strength of the roof glass.

7. The four roofing types unveiled at Tesla’s solar roof launch (left to
right): Tuscan Glass Tile, Slate Glass Tile, Textured Glass Tile,
Smooth Glass TileWith these four different designs, Tesla can make inroads into both the solar
industry and roofing industry and offer competitive advantages in both. Solar
panel warranties are often a huge selling point for homeowners who are
concerned about the longtime production value and durability of their solar
panel systems.

8. In solar roof tiles there are
three kind of material used by
the TESLA which have
physical appearance as a
normal tile. These tiles have
three layers, which are as
color louver film, high
efficiency solar cell, tempered
glass.

10. POWE SUPPLY SYSTEM
The Powerwall and Powerpack are rechargeable lithium-ion battery
stationary energy storage products manufactured by Tesla. The Powerwall
is intended to be used for home energy storage and stores electricity for
solar self-consumption, time of use load shifting, backup power, and off-the-
grid use.
The larger Powerpack is intended for commercial or electric utility grid use
and can be used for peak shaving, load shifting, backup power, demand
response, microgrids, renewable power integration, frequency regulation,
and voltage control.

13. ADVANTAGES
Although the upfront investment seems high, there are several advantages to
installing Tesla solar tiles on your roof:
• Aesthetically, Tesla solar tiles put traditional solar arrays to shame. There
are no bulky frames or visible wiring and junction boxes. The tiles look like
regular roofing tiles - which could significantly increase the value of your
home.
• While the initial purchase and installation costs for Tesla tiles are
impressive, like other solar options, this product will pay for itself.
• Because the design of these tiles makes them nearly indestructible, Tesla
offers to replace their tiles as long as you own your home – without time
limits.

14. • The key advantage that solar tiles have over solar panels is their
attractive finish and seamless integration with your home’s
architecture.
• The tiles have been designed to work in partnership with Tesla’s
Powerwall 2.0 Solar Battery which, although optional, would enable
you to store the energy produced by the tiles for use during the night or
in the event of a power cut, bringing the ambition of energy
independence a little closer to reality.
• Many listed properties aren’t allowed to have solar panels installed but
solar tiles may be a viable alternative.

15. CONCLUSION
• The real innovation is the production of a solar system that is a roof first.
While building-integrated photovoltaics have been around for some time, the
concept of a completely solar roof has not yet been successfully brought to
market.
• The price and the actual solar efficiency of these Tesla glass shingles are two
major factors that were only ambiguously addressed by Musk in the launch.
• Ultimately, the solar roof is a premium product made of quartz and is
virtually unbreakable. Though nationwide estimates are still unclear, Tesla
has said their roof will cost $21.85 per square foot. The simple context is that
the roof will be very expensive compared to any common roof installation but
could be competitive in terms of long-term net benefit when the energy
savings are factored in.
