This innovation will not benefit bitcoin mining; not even in very hot countries with expensive electricy (though I don't believe there is that correlation).  When you buy bleeding edge tech for electricity generation, you are bypassing economies of scale.  The result is very expensive electricity.  It's great for wealthy people who want to call themselves "green" while still purusing wretched excesses. 
 Maybe with hefty government subsidies... but I have serious doubts.

if it is only a matter of price then maybe you are right but for solar panel usage you only need solar energy (a clear sky to see the sun) and it has nothing to do with the temperature although hotter countries have more clear sky and sun exposure but it is a strange thing to say.

and i think this is great but it is one of those things that we are too far away from seeing it in real world applications and be used.

electricity has never been the biggest problem.

tiles are also not free.
so although you are not paying a monthly electric bill you are either repaying a loan to have the panels or paying a larger amount upfront to then get the savings (returns) later.

the main costs are the asics themselves

afterall..  due to hashrate rises every day, and difficulty rises every fortnight. its deemed best to try and get ROI within 6 months.


so even at zero.. you are still having to think about the.. THOUSANDS of $ to buy the tiles.
as for normal access to electric
one asic
at 20cents/kwh for 6 months electric = $900
at 10cents/kwh for 6 months electric =$450
at 5cents/kwh for 6 months electric = $225
and the $1600 to buy an asic

so paying thousands on solar power vs $225-$900 using normal electric providers is not a saving.

solar panels are only cheaper based on their 10 year lifespan, not on making bitcoin profits in 6months

I would say that these Solar roofs are good for providing electricity for using simple non power sucking household appliances. Using it on a miner seems very wasteful and will honestly with the investment that you are putting into the Solar roof, you probably wouldn't make a lot on the short term profits that you are trying to make up your losses with.

This is a very important point.
If you look at the cost of a solar panel setup, usually you are looking at a 10 year or 20 year timeline to get ROI.

If you are talking about Bitcoin mining you already have to factor in the ROI of an ASIC miner costing upwards of $1500-2000 for new units.
Adding in solar panels is another big investment.
There are some members here who have done solar panel mining. I'm sure they could provide some numbers on the cost/ benefits/ ROI time.

More miners, more competition so it can be good for bitcoin miners. I don't checked the prices however I think it will be expensive and miners will have ROI not so fast, not a big deal here.

Just watched a documentary on why solar is going nowhere and it was due to the utility companies grabbing all the lobbyists and pushing costs up on solar power.
Also getting rebates cancelled in effect making it very hard to do business in solar in the States,so cheaper will not really be the answer. It has more to breaking these companies that act like the mob with their protectionist attacks.
Not a enviromentalist but these lobbyists are a dark aspect of the American government and need to be sorted.

Its great since the cost of electricity here in my country is very expensive. But i think it takes a lot of time to take back the money for buying this stuff because i dont think the profit will give you enough profit on mining. But its a lot cheaper than spend money for monthly electricity cost.

Even for covering the total electricity of the mining rig like an ASIC s9 for days will just like impossible things,
https://www.solarpowerauthority.com/how-much-does-it-cost-to-install-solar-on-an-average-us-house/

This calculation just depending with the power consumption in the USA if applied in the other area will be much expensive than this one. Just agree with franky.

in short
bitmain are making a new mining facility.. and guess what.. not a single solar panel will be there
so if bitmain cant see solar panels as a cost saving.. forget it
