Tesla Solar Roofs: Cheaper, Infinity Warranty, Plus Solar Power

Published

7 minute read

Let’s jump right in, Canadian’s can pre-order here: https://www.tesla.com/en_CA/solar

Tesla released today all the information to order its new solar roof tiles products – starting with the smooth black glass tiles and the textured glass tiles, as reported earlier today.

Of course, the most important information that people were waiting for is price. CEO Elon Musk first hinted that it would be cheaper than a regular roof after accounting for energy savings, and later said that Tesla’s solar roof could cost less than a regular roof – even before energy production.

Tesla pretty much delivered on both depending on how you look at it.

The company says that the “typical homeowner can expect to pay $21.85USD per square foot for a Solar Roof.”

What is important to understand is that not all tiles on the roof would be solar tiles. It depends on the energy needs of the household and shading coming from structural items such as dormers. For the house pictured above, all the tiles are from Tesla, but only some of them have solar cells in them that can generate electricity – though it’s not visible from street view.

The $21.85 per square foot price point was calculated for a roof where 35 percent of the tiles are solar (solar tiles cost more per square foot than non-solar tiles). During a conference call with journalists today, Musk said that in some cases, depending on the roofs, customers will be able to have up to 70% solar tiles, but in most cases, it will be about 40%.

They released a calculator directly on their website, which any homeowner in the US can use to get an estimate based on data from Google’s Sunroof project. Here’s an example for a home in Maryland with both 70% solar coverage and 40% solar coverage:

Ultimately, Tesla sees that most customers will essentially be paid to have a new roof, when accounting for energy generation and the solar incentive.

They are including an installed 14kWh Powerwall 2 in the quotes. It can be removed, but Tesla believes that most people will want to have the home battery pack for backup energy in case of an outage.

Tesla broke down the cost of both its solar tiles and non-solar tiles against traditional roof solutions.

The company estimates that its non-solar tiles are cheaper than regular tiles and its solar tiles are cheaper than anything else, but only when accounting for energy generation (actual cost of solar tiles is $42USD/sq-ft):

The value of Tesla’s solar roof is closely linked to its durability and its ability to generate electricity over decades.

Musk previously discussed the possibility of making the warranty last for the lifetime of the house on which it is installed and they actually did it:

“Made with tempered glass, Solar Roof tiles are more than three times stronger than standard roofing tiles. That’s why we offer the best warranty in the industry – the lifetime of your house, or infinity, whichever comes first.”

That’s for the tiles themselves. The solar power generation is guaranteed for 30 years, which is on the higher end in the solar panel industry:

During a conference call with journalists, Musk and Peter Rive reiterated their confidence in the new product’s durability, which ultimately, of course, is reflected in the warranty.

They put these through every test imaginable, including shooting a large ball of hail:

The first two tiles, smooth and textured, are going into production this summer. They decided to go with those tiles first because they received the highest number of inquiries.

A $1,000 USD deposit is required when ordering a system online now. Homeowners outside of the US can also order, but they should not expect installation until next year. Musk said that he expects strong demand and for the company to be production constrained on the tiles.

Tesla says that it will manage the entire “Solar Roof experience—from the removal of your existing roof through design, permitting, installation, operations and maintenance of the new Solar Roof.” The company estimates that the installation should take roughly the same time to install as a tile roof installation, which is typically 5-7 days.

They recently updated their mobile app in order to prepare for the integration of the solar products and the Powerwall.

Musk concluded the press call by saying: “When you think of a sustainable energy future, you want roofs to be beautiful and generate energy from the sun. That energy can then charge Powerwalls and electric vehicles. That’s the future we want.”

Tesla solar roof products are perfect for homeowners who want solar and need a new roof relatively soon, but a regular solar panel installation is still a good solution for people who don’t need a new roof. Solar and energy storage prices are highly dependent on your market (electricity cost, gov incentives, etc.) and your property. We suggest to get quotes from more than one installer to make sure you get the best energy solution for your place.

Electric cars just another poor climate policy

Published on

From the Fraser Institute

By Bjørn Lomborg

The electric car is widely seen as a symbol of a simple, clean solution to climate change. In reality, it’s inefficient, reliant on massive subsidies, and leaves behind a trail of pollution and death that is seldom acknowledged.

We are constantly reminded by climate activists and politicians that electric cars are cleaner, cheaper, and better. Canada and many other countries have promised to prohibit the sale of new gas and diesel cars within a decade. But if electric cars are really so good, why would we need to ban the alternatives?

And why has Canada needed to subsidize each electric car with a minimum $5,000 from the federal government and more from provincial governments to get them bought? Many people are not sold on the idea of an electric car because they worry about having to plan out where and when to recharge. They don’t want to wait for an uncomfortable amount of time while recharging; they don’t want to pay significantly more for the electric car and then see its used-car value decline much faster. For people not privileged to own their own house, recharging is a real challenge. Surveys show that only 15 per cent of Canadians and 11 per cent of Americans want to buy an electric car.

The main environmental selling point of an electric car is that it doesn’t pollute. It is true that its engine doesn’t produce any CO₂ while driving, but it still emits carbon in other ways. Manufacturing the car generates emissions—especially producing the battery which requires a large amount of energy, mostly achieved with coal in China. So even when an electric car is being recharged with clean power in BC, over its lifetime it will emit about one-third of an equivalent gasoline car. When recharged in Alberta, it will emit almost three-quarters.

In some parts of the world, like India, so much of the power comes from coal that electric cars end up emitting more CO₂ than gasoline cars. Across the world, on average, the International Energy Agency estimates that an electric car using the global average mix of power sources over its lifetime will emit nearly half as much CO₂ as a gasoline-driven car, saving about 22 tonnes of CO₂.

But using an electric car to cut emissions is incredibly ineffective. On America’s longest-established carbon trading system, you could buy 22 tonnes of carbon emission cuts for about $660 (US$460). Yet, Ottawa is subsidizing every electric car to the tune of $5,000 or nearly ten times as much, which increases even more if provincial subsidies are included. And since about half of those electrical vehicles would have been bought anyway, it is likely that Canada has spent nearly twenty-times too much cutting CO₂ with electric cars than it could have. To put it differently, Canada could have cut twenty-times more CO₂ for the same amount of money.

Moreover, all these estimates assume that electric cars are driven as far as gasoline cars. They are not. In the US, nine-in-ten households with an electric car actually have one, two or more non-electric cars, with most including an SUV, truck or minivan. Moreover, the electric car is usually driven less than half as much as the other vehicles, which means the CO₂ emission reduction is much smaller. Subsidized electric cars are typically a ‘second’ car for rich people to show off their environmental credentials.

Electric cars are also 320440 kilograms heavier than equivalent gasoline cars because of their enormous batteries. This means they will wear down roads faster, and cost societies more. They will also cause more air pollution by shredding more particulates from tire and road wear along with their brakes. Now, gasoline cars also pollute through combustion, but electric cars in total pollute more, both from tire and road wear and from forcing more power stations online, often the most polluting ones. The latest meta-study shows that overall electric cars are worse on particulate air pollution. Another study found that in two-thirds of US states, electric cars cause more of the most dangerous particulate air pollution than gasoline-powered cars.

These heavy electric cars are also more dangerous when involved in accidents, because heavy cars more often kill the other party. A study in Nature shows that in total, heavier electric cars will cause so many more deaths that the toll could outweigh the total climate benefits from reduced CO₂ emissions.

Many pundits suggest electric car sales will dominate gasoline cars within a few decades, but the reality is starkly different. A 2023-estimate from the Biden Administration shows that even in 2050, more than two-thirds of all cars globally will still be powered by gas or diesel.

Source: US Energy Information Administration, reference scenario, October 2023
Fossil fuel cars, vast majority is gasoline, also some diesel, all light duty vehicles, the remaining % is mostly LPG.

Electric vehicles will only take over when innovation has made them better and cheaper for real. For now, electric cars run not mostly on electricity but on bad policy and subsidies, costing hundreds of billions of dollars, blocking consumers from choosing the cars they want, and achieving virtually nothing for climate change.

Liberal MP Paul Chiang Resigns Without Naming the Real Threat—The CCP

Published on

The Opposition with Dan Knight     Dan Knight

After parroting a Chinese bounty on a Canadian citizen, Chiang exits the race without once mentioning the regime behind it—opting instead to blame “distractions” and Donald Trump.

So Paul Chiang is gone. Stepped aside. Out of the race. And if you’re expecting a moment of reflection, an ounce of honesty, or even the basic decency to acknowledge what this was really about—forget it.

In his carefully scripted resignation statement, Chiang didn’t even mention the Chinese Communist Party. Not once. He echoed a foreign bounty placed on a Canadian citizen—Joe Tay—and he couldn’t even bring himself to name the regime responsible.

Instead, he talked about… Donald Trump. That’s right. He dragged Trump into a resignation about repeating CCP bounty threats. The guy who effectively told Canadians, “If you deliver a Conservative to the Chinese consulate, you can collect a reward,” now wants us to believe the real threat is Trump?

I haven’t seen Donald Trump put bounties on Canadian citizens. But Beijing has. And Chiang parroted it like a good little foot soldier—and then blamed someone who lives 2,000 miles away.

But here’s the part you can’t miss: Mark Carney let him stay.

Let’s not forget, Carney called Chiang’s comments “deeply offensive” and a “lapse in judgment”—and then said he was staying on as the candidate. It wasn’t until the outrage hit boiling point, the headlines stacked up, and groups like Hong Kong Watch got the RCMP involved, that Chiang bailed. Not because Carney made a decision—because the optics got too toxic.

And where is Carney now? Still refusing to disclose his financial assets. Still dodging questions about that $250 million loan from the Bank of China to the firm he chaired. Still giving sanctimonious speeches about “protecting democracy” while his own caucus parrots authoritarian propaganda.

If you think Chiang’s resignation fixes the problem, you’re missing the real issue. Because Chiang was just the symptom.

Carney is the disease.

He covered for it. He excused it. He enabled it. And now he wants to pose as the man who will stand up to foreign interference?

He can’t even stand up to it in his own party.

So no, we’re not letting this go. Chiang may be gone—but the stench is still in the room. And it’s wearing a tailored suit, smiling for the cameras, and calling itself “leader of the Liberal Party.”
