There‘s probably no better and easier place for PV than Australia. Lots of sun, single detached houses, large roof areas. It‘s probably the place where all roofs should have PV.

Now look at the suburban US.
Seems like an even better place to do rooftop solar.

Flying into Texas is so depressing. So many rooftops, so much sun, so few solar panels.
And then every year we see so many hundreds (thousands?) of weather-related deaths there because they've let their grid go to shit.
EDIT: For some understanding of just how much Texas is letting their natural resources lay fallow, here you go:

Texas has the 2nd most solar in the US behind California

Texas is 24th in solar installations per capita despite being smack in the sun belt:

It's growing, which is encouraging, but California's per-100k installations is 9x Texas's.

The only reason I mentioned that is I noticed the opposite of what you are describing above (i.e. rooftop solar everywhere) in Austin. I'm not sure per capita is relevant given that each state has a fixed amount of land mass but Texas has been building the 2nd most solar per year for the past few years, which is great. Not to mention that Texas has fewer sun hours and higher temperatures than California (solar panels are as much as 25% less efficient when temperatures are high).
Texas' grid issues are a completely separate issue and, if anything, adding non-firm power (i.e. solar) to the grid could exacerbate their issues (I don't think that adding solar is what is causing their grid issues though, just mismanagement).
Texas should be applauded for massively increasing their solar installations over the past few years, not criticized because they can't keep pace with California.

They're not even keeping pace with New England, or the entire northeast outside of Pennsylvania. Texas absolutely should be criticized for that.
And selecting Austin as representative of the whole state is disingenuous for the obvious reasons.
crappykillaonariva t1_ivg41ly wrote
Are you looking at this on a per capita basis? Again, I think total installations is the better metric to use but there is a lot of solar development in Texas and there are plenty of other states in great climates for solar that aren't developing solar as fast as Texas is. Texas has a lot of issues with their electrical grid but solar isn't one of them IMO.
​
I think Texas is an interesting example because they really aren't building solar for climate reasons, they are building it for economic reasons (i.e. solar projects are profitable). I think the end goal should be to generate our energy from solar, wind, hydro and nuclear and proving that solar is a profitable endeavor will only further that goal.
​
I never insinuated that Austin is representative of the whole state and am not being disingenuous. It was an anecdote in the same vein as your earlier comment re flying into texas and not noticing solar panels.

The solar industry is booming in Texas. I see it on a ton of houses. It’s very expensive though. We are installing in on our home. I wish our electric companies had better net metering programs like other states though.

There are climate regions in the US that, while still possible, have less benefit than Australia. places with heavy snow or lots of rain/overcast.
Hell, i'm in a GOOD area for solar, and still doesnt make sense for me to get panels because my roof is covered by trees almost all the day.
Which is a benefit of its own, as it keeps my cooling costs low in the summer.
Masark t1_ivfm07z wrote
Snow doesn't actually affect solar that much. At latitudes where snow is significant, the panels will be tilted enough that the snow largely just falls off.

i've head that before, but my aunt has to go out with a broom and brush the snow off her tilted panels after heavy storms.

Which means that regular snow doesn't affect the panels that much.
It's only after heavy storms that you want to clear the panels, which is no different than the clearing of the roof you would need to do anyways.
Adventurous_Ad4950 t1_ivgjyrx wrote
There should be better maintenance systems for domestic PVs. Not everyone has the ability to climb on the roof and clear snow every time there’s a heavy storm (and hello climate degradation). Hiring a service to do it for you is not in everyone’s budget either.
Ok_Dependent1131 t1_ivfuhbj wrote
Yup. But cooling costs could be zero after a few years when the ROI of the panels and batteries is worked down.
ChildrenAreOurDoom t1_ivg0ufv wrote
It makes no sense for me to cut down trees that provide me with a lot of cooling benefit, hurt the ability of the planet to absorb air pollution, hut the ability of the ground to absorb storm water, hurt the planet for the production, shipping, and resource extraction to make the panels and batteries, and to make my property look barren, just so i can use generated energy for cooling.
Ok_Dependent1131 t1_ivgjkpt wrote
I mean, I have trees around my house but I wouldn’t have to fell them completely to get sun to hit my roof. It’s not all or nothing. Also people can put solar panels on the ground too but city living makes that tougher

If rooftop solar was as affordable in the US as it is in Australia I think it would be just as popular. I get very jealous when I see Australians talk about how much their installs cost.
Cazza81 t1_ivednoe wrote
The Australian government offered a lot of incentives to install solar panels. I'm in one of the hotter states and I'd say it's closer to half of all places that have rooftop solar panels - ours do well even in Winter (very mild winter).
