Returning to
@FrankSG for a moment.
One topic he covered in some detail was solar roof including mentioning a few companies making some offering in that arena. There have been quite a few attempts, almost all fo which have failed.
IMHO, probably among the best is this one:
eMetal, eRoll, eFlex & Customization | Flisom
They're Swiss and have seemingly strong backing plus a diverse technical base including a former Tata Solar executive. Their approach si totally different than is Tesla in that they do not actually have a roof replacement product.
There are probably some dozens of examples, most fo which will probably fail.
The point of that introduction is that I agree with Frank that Tesla has stuck with the research and iterations and thus now seems to have the only competitive roof replacement in the world, certainly the only one that is system integrated with grid tie capacity through Powerwall. It does not require high technical ability to adopt this solution.
As investors have ignored this development year after year, ourselves included, we appear to have a working solution, albeit arriving in the infamous 'Elon time'. As investors the problem with this one is that it is the Model S of roofs. How can anybody imagine something that has never been done before?
My personal opinion is that any responsible calculation of the potential for this will result in growth that is unimaginable. After all, California now is mandating solar on new construction:
California Gives Final OK To Require Solar Panels On New Houses
Even with new single family homes declining:

We still have a 100% certain market for ~90,000 houses that WILL have need for a roof and WILL have solar panels.
Since Tesla is the only viable roof-replacement vendor (my bad: that seems just like a monopoly, does it not?) one can safely assume Tesla could supply, say, half fo those were the capacity to exist. Certainly some large portion would also have storage and grid intertie so those would be easy Tesla sales.
Skip the financial implications for a moment. The problem is purely and solely production capacity and delivery ability. Tesla is already proven over and over that they perpetually are capacity constrained.
Someone with more perspective might actually judge how quickly Tesla can expand solar roof/ Powerwall integration.
South Australia has already proven that residential grid tie with distributed storage can yield substantial benefits to grid stability.

Grown up this product line would dwarf automobiles. Further it is quite plausible that serving only locations which have solar power conducive climactic conditions would have an addressable market of 500,000 per annum worldwide. At $10,000 per roof that would be $US five billion (e.g. five thousand million US dollars). In any realistic view those are ridiculously low numbers. California alone WILL have roughly 20% of those units with considerably higher average cost.
My point is that we need to take Tesla Energy seriously this year! Remember that the peaker replacement market is already proven as is the solar/wind power stabilization market and there are more than 1200 peakers in operation in the US alone. Tesla will not even have the largest share of those markets but they will have very lucrative ones precisely because of the Tesla software advantage in grid services.
Next we have hundreds of thousands of islands, and untold thousands off locations for whom desalination plants have already proven to be practical with solar plus storage.

So,
@FrankSG or others with time, inclination and skills, here's the pitch.
TE is devoted to Elon's mission and is executing already but is invisible to the investment community including us. We are, after all, The Tesla
Motors Club. So, what will be do about that in 2020?
Remember, these opportunities dwarf cars. That is what JB told us all in 2010 and we all ignored him. Elon has repeated much of this and we all ignore him too.
Next thing we know he'll say something impossible and ridiculous like recovering first stage rockets. If nobody stops him he'll try to recapture fairings too.
