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.

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 is 24th in solar installations per capita despite being smack in the sun belt:
https://solarpower.guide/solar-energy-insights/states-most-solar-installations
It's growing, which is encouraging, but California's per-100k installations is 9x Texas's.
crappykillaonariva t1_ivfpbbd wrote
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.
MLS_Analyst t1_ivfq0p4 wrote
> 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.

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.

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.

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.

Yup. But cooling costs could be zero after a few years when the ROI of the panels and batteries is worked down.

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.

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

I figured this out after talking to a few people on hear who seemed really angry that solar was crazy unaffordable. From my perspective it's expensive, but the panels are the cheapest part and the reduction in energy means they should pay themselves back double over their life time.
I got 2.2kW worth of panels added to my roof. The panels cost about £700 ($750). The inverter and other equipment was another £1500. The scaffolding was £700, and the installation was £1200.
£4200 total ($4500) and halved our energy bill!

That's about 10x the size of mine, so actually not too surprised it's 10x the price!
To have that much solar power on my house in the UK I think I would need to register as a power station, if I wanted to also connect and input to the grid! (Don't hold me to that, it's just anything up to 5kW has a really simplifying process and no planning permissions or needed or anything).
In the UK average houses only really need 2-3kW system, which would basically meet all needs in the summer but not really touch the sides of usage in winter - we get so little sunlight in the winter it's not even worth trying.
It's very, very rare for a residential property to have above a 5kW system.
But then, we don't really use cooling and we tend to use natural gas for heating. So while we only use 10-15kwH of electricity per day, we use a lot more in natural gas for heating over the winter.

Well HOAs are legally bound to allow for solar installations (Section 202.010(b) of the Texas Property Code states that “a property owners’ association may not include or enforce a provision in a dedicatory instrument that prohibits or restricts a property owner from installing a solar energy device.”). Most warranties on our quotes were 25 years - the equipment under this warranty is guaranteed to produce around 90% on the guaranteed starting production. Not trying to talk you into anything. Just made sense financially in the long run for us.

In tennessee the tennessee Valley authority has an application process for putting power back into the grid. Which includes changing the meter on your house to show what's pulled in and put back.
But they limit you to 12 panels on your house. Loop hole to that being you can add 2nd meter to your address. Which would then most likely allow an extra 12 panels. But for this house and it's 1 meter 1 fuse box we are maxed.
We opted out of putting back instead set it up to supplement what we use. Lowering our power bill bout 100+ a month.

Nothing in your post is even remotely the truth.
-
Power companies use renewable energy sources themselves. They don't like rooftop solar with feed in tariffs because you're not paying for transmission costs. Generation is only one part of the total cost of electricity. Plus utilities profit is highly regulated.
-
Insurance companies do not care about your rooftop solar unless it makes it more expensive for them in the event of a claim such as in areas with frequent storm damage.
Solar works great in the US in areas that support it. And contrary to your claim, it's the solar lobby that has the upper hand over the utilities companies. In California for example, all new construction homes are required to have solar, and natural gas is scheduled to be banned on new homes starting next year.

The problem with this is that the energy companies are doing everything they can to prevent solar being an attractive option. Most companies offer 4-6c/kWh for energy exported to the grid, while charging you 25-30c/kWh for energy imported from the grid.
So the best thing you can actually do with your energy is fully use it, but due to the constant sun in AU, that's nigh impossible - even with a small 5kW system.
If energy was brought back to a publicly owned service, I imagine they would very quickly build large battery banks to absorb the extra, and distribute it at night when it's not being generated as much. There are some companies that are working towards this system (known as a Virtual Power Plant - or VPP), but they are always heavily in favour of the company implementing them, not the customers.

However, the point that they can be used as a substitute for exterior wall flashing, even if the primary purpose of producing electricity is significantly reduced by not being positioned for maximum efficiency, was not lost on me.
I wonder what purposes they'll serve at the end of the decade when they have reduced in cost by another 75%, and the 'possibility space' continues to open...

I think another benefit of rooftop solar related to your second point is that it also lowers the demand on the grid. It also adds some ability to develop disaster resiliency in terms of having hyper-local power generation.
Solar still needs to contend with the fact that demand peaks are not aligned with output peaks (ie the famous “duck curve”) - which is of course where storage and other power sources need to be used in tandem. Still, rooftop and large solar installations will both need to be used.
