In my opinion, the Tesla Solar Roof really appealed to people who wanted good looks. They probably already have their “forever” homes and are not thinking of moving at all. It is more about the emotional attachment to this part of your home than its functional aspects. You can buy a $100 dining table from IKEA or you can buy a $1,000 dining table from Pottery Barn or you can buy a custom $5,000 dining table made from…

Yeah and I think that's fine - and as I mentioned below my own reasons for installing solar panels were not just financially motivated. But the economics are also hugely important. Most people don't buy $5,000 tables, and most people don't buy Tesla Solar Roofs - the article says they sold 3,000 total in the last decade. And I don't think Tesla wants to be in the bespoke roof business - they want to be selling to the…

The boss wishes for a product distorts the target audience selection?

They could have had that- if they had a standardizeable install method. Aluframes for the roofs, have bespoke solarpanels just slide in and lock up as roof over roof install. The problem there was the statics not working out

No - these numbers likely do not factor in opportunity cost. And yes, you can probably earn a better return elsewhere. But the reasons that I installed rooftop solar were: * Diversification. These days stocks, bonds, real estate, crypto, and even precious metals are increasingly correlated [1]. Solar panels offer pretty consistent returns regardless of what is happening in the stock market. * Backup power. I live in…

I'm in the same camp as you. I'll add that my panels are returning 16% on capital spent, and it's going up as electricity prices go up. So, yes, I could probably get a higher return if I invested that capital elsewhere, but, apart from the diversification, I get benefits beyond the raw financial return. Firstly, earlier this year, we had a cable coming into the house fail. By the time the electrician and city had don…

In an average year (not the past 4), 16% would be amazing. That it’s effectively guaranteed and will almost certainly increase every year is icing on the cake. I’d take that trade any day.

Tesla’s Solar Roof uses string inverters rather than micro-inverters or power optimizers, which means that partial shading on any section of the roof can shut down production for that entire string. This is a significant design limitation that competing solar installers address with panel-level optimization technology from companies like Enphase and SolarEdge.

This seems to be overblown. I've seen plenty of string inverters around without issues, I'm not sure why this being used against Tesla in particular.

> $106,000 before incentives, What's the capacity though. Either way this seems extremely high unless we are talking in terms of like 100kw or something. For reference, I recently installed hybrid/net-metered system set up at my home in India; 7kw solar with a 20kWh battery for around $10K. The biggest cost is for the batteries though. The panels themselves have become extremely low price and the prices continue to f…

It's not just solar panels, it's a roof replacement and solar panels. In high COL areas, the roof alone would likely cost you $10k+ these days.

10k for a SFH roof seems extraordinarily cheap to me for any COL area. I would expect around 50k-60k for a 1000 sq ft roof (not US).

> The economics never worked either. An average Tesla Solar Roof costs approximately $106,000 before incentives, compared to roughly $60,000 for a traditional roof replacement plus conventional solar panels — a $46,000 premium. The payback period stretches to 15-25 years, compared to 7-12 years for traditional panels. Yikes that’s a lot of money. For most people buying solar, I think payback period is probably the bi…

I would love some kind of solar, but when I know how cheap it is to install it in places like Africa AND use cutting edge chinese solar/battery tech, my enthusiasm to pay a USA premium makes me just close the tabs. It's too expensive in america for some reason.

You need to shop around. Problem is solar companies just hiring contractors with little value add. Spend some time looking for contractor yourself and you’ll easily save 30%.

Yeah, Elon's whole shtick is make things scale up that everyone else thinks can't scale up. Sometimes it works (batteries), sometimes it works spectacularly well (Falcon 9), sometimes it fizzles out because it turns out everyone else was right (tunnel boring, solar tiles).

Shame.. I've seen one of these in person on a high-end home and its a very nice looking product. I assume the lifespan would be similar to a metal roof.

Regular solar panels work well but are an eyesore on a nice home.

I can hardly see my panels even if i wanted to

In both cases I'm somewhat curious why seemingly no middle-man 'free solar roof' companies have sprung up where they install it with some sort of arrangement where the panels are free, but they get 90% of the generated revenue until it's paid itself off and then some. So you get a small electricity discount for many years and then eventually a much larger one, and free panels on top.

If they can work out the economics to the point that it's more viable than something like treasuries then I don't see the issue? Of course there's some potential market and other variability, but if this business model is sound then Lloyd's is there to insure it?

> The middle ground is integrated solar panels, where you have normal sized panels but they are flush with the rest of the roof and there are no tiles underneath them Flush with the rest of the roof seems like a mistake. What if you need/want to replace them with a different sized panel?

That and op said it's more expensive. Why would you do it flush, then? Looks? Eh, I prefer practicality over form and many architects would agree with being more honest.

Looks, no need for bird caging to stop nests underneath the panels, and I don’t believe it is particularly more expensive if you do it when replacing the whole roof. It’s more expensive if you don’t want to replace your roof.
