why tesla\'s solar roof is a bad buy

It\'s a Roof!
Solar panels!
This is luxury!
Everyone needs electricity.
The roof is needed for everyone.
Tesla Solar Roof is not needed for everyone.
In fact, Tesla\'s solar roof is the gold Apple Watch version of the energy industry.
When Tesla began accepting a $1,000 deposit on its solar roof in California alone, there was a lot of reports praising the manufacturer for exceeding expectations in price.
The roof is \"cheap enough to catch fire,\" Bloomberg claims \".
CNBC noted an estimated $21.
$85 per square foot.
£ 65 per square foot is less than the consumer report forecast.
Greentech Media highlights the durability of the tiles and the \"unlimited warranty \".
\"At the time of the release of the Apple Golden Bell edition, panting experts claimed that the watch was priced at $17,000, which may be too cheap, and that the\" $10,000 Apple Watch \"would not be crazy.
\"Of course, 18 months later, the gold Apple Watch version was declared dead.
Apple\'s mistake, or at least the mistake of Apple\'s misleading reporter, is to compare the Apple Watch version to Patek Philippe, Rolex or Cartier.
In fact, Apple Watches are competing with fitness bands and other wearable electronics that enhance smartphones by providing notifications, alerts, and environmental awareness involved with other peripherals.
The $17,000 watch may not be unreasonable.
A $17,000 fitness band is ridiculous.
Similarly, Tesla misled the public by comparing the solar roof with the tile and slate roof, rather than the various forms of solar energy.
As you can see, a real comparison is not flattering for Tesla.
Infinity MythA\'s $10,000 electronic watch doesn\'t make sense because it\'s out of date in a year.
You can\'t upgrade or replace the internal organs of the Apple Watch, and you don\'t want to show off a useless consumer electronics.
While the time frame is a bit different, so is the Tesla Solar Roof.
Tiles may always exist, but electronics in string inverters are usually protected for 12 years, and the production potential of solar panels will drop by 1% in the first year and a half, this led to the elimination of solar power generation capacity within 30 years.
At this point, even if the material that protects the house from rain keeps it intact, you have to replace the solar roof.
This is a video of Tesla promoting its solar roof in the hail test: Please note that the traditional slate and tile roof material is not properly installed to show its weaknesses.
Most of the tile tops are a more solid cement structure.
Still, Tesla\'s solar roof durability test uses some tricks to prove that it is more durable than a regular roof.
How about comparing a Tesla Solar Roof to a standard solar panel?
This is the 2013 Solar World hail test: solar panels were not damaged by hail.
If you put solar panels on a standard roof, they protect the roof and extend the life.
You can then remove the panels and replace them when they exceed useful service life.
You will not leave them forever because they have not been damaged by hail.
Fish is not a bird either: Tesla\'s solar roof is not very good at solar energy, and it is not very good at the basic value proposition of rooftop Tesla, that is, it is a high
The quality roof is not so expensive because you save electricity.
The problem with this statement is that the way you judge the roof is completely different from the way you judge the energy.
You want to make the roof strong and attractive and keep you dry.
You want your electricity to be as cheap as possible.
$0 for electricity.
$19 per kilowatt hour has no added benefit to electricity. 07 per kWh.
This is the ultimate commodity.
To illustrate its value, Tesla offers a handy chart for comparing solar roofs to common roofs: The chart shows that the cost of solar roofs plus power generation, the negative cost per square foot is about $2.
Various non-expenses
The price of a solar roof is between $6 and $17 per square foot.
John Cromer, a mechanical engineer who is a solar educator and a regular visitor to Reddit, fixed the chart for Tesla: If you think
Quality solar panels attached to the top of the standard asphalt wood tile roof, when calculating the energy value generated, the cost of your new roof and new panels is $13 per square foot.
This will save more money!
According to HomeAdvisor, the average roof price for full installation is $7,060.
The average roof is 3,000 square feet, which means the cost of the new roof is $2.
One square foot.
The average home will support a 7 KW solar cell array for about $3 at the moment.
Install 20 watts per watt for a total cost of $22,400.
Plus the $7,060 roof and your solar system plus your new roof for $29,460.
This is much lower than the cost of $65,500 for Telsa solar roof, which is 3,000-square-
$21 roof.
85 square feet.
According to Dow\'s experience in solar panel products for power stations, the power generation capacity of solar panels may be lower than that of standard solar panels.
The Dow gave up their offer because making photovoltaic products is a cut. Throat business
Winners must continuously reduce prices and increase power capacity by making manufacturing more standardized and efficient.
You can\'t compete with unique, differentiated products on the basis of goods.
Energy is a commodity. Head-to-
We fought a positive battle. to-
On the standard solar panel installation, the actual re-installation will be
Roof and solar installation for our partner company Buch deals
Founder and Senior Vice President of Systems, Tesla Solar Roof.
According to the actual cost of Buqi, we have increased the installation size of Buqi to provide an appleto-
Apple compared the results with Tesla.
This is Tesla\'s estimate: Reverse engineering Tesla\'s calculations offset the cost of $150 a month for about $0.
10/kWh, the power capacity of the roof seems to be around 8 KW, which makes sense considering the lower power value of the solar tile.
According to Tesla, 60% of the wooden tiles have solar energy.
Generate properties.
Here is the Tesla Solar Roof Summary: This means 30-
Annual service life of Tesla roof-
The solar integrated system is $1,700.
We used Geostellar\'s estimation tool (
Disclosure: I am founder and CEO)
Compare: to offset his $150 per month electricity bill, Buch will install 40 solar panels for £ 10, each with a power of 270 watts.
System 8 KW
Here is a summary of the solar installation of Buch: this means 30-
The standard solar panels on the newly installed roof of Boucher have an annual service life of $33,600.
Butch lives in West Virginia, where utility rates are the lowest in the country.
In other areas, the gap between Tesla\'s savings and the savings of standard solar panels will be even greater.
Use the estimation tool on Geostellar to compare Tesla\'s solar roof with various solar panel manufacturing and models for your own home.
Iron Man or confidant?
Because he is very successful and is clearly committed to solving the major problems facing humanity, Tesla\'s founder and CEO Elon Musk usually gets a pass in the media when his ideas are out of datetarget.
As far as Tesla\'s solar roof is concerned, it could damage the solar industry and set us back in the fight against climate change.
As I reported in a previous column, when people wait for Musk\'s promised solution to be \"better\", Tesla can stop the adoption of batteries and solar panels.
Today, everything we need to solve the energy and climate crisis is in place.
Brent Todarian, a real urban planner who knows what he\'s talking about, has brilliantly refuted Musk\'s recent TED talk about \"boring companies, musk\'s efforts appear to be aimed at building tunnels under the city to ease traffic congestion.
Considering Tesla electric cars, Hyperloop and boring companies, Musk is clearly passionate about traffic.
Let\'s hope Musk focuses on the development of electric aircraft, which he recommended to Tony Stark in the iron man Guest Series.
Solar energy is a truly boring industry that must be maintained in order to compete with traditional electricity on a kilowatt-hour basis.
Musk\'s promotion for Tesla\'s solar roof is not as good as Maggie.
Monorail, \"music-based people.
I look forward to seeing the hot weather later next year when the Tesla Solar Roof is declared dead as the gold Apple Watch version.
