No.Efficiency in PV is not that important. If PV's were 100% efficient then the temperature of the panel supports underneath would plunge to absolute zero and destroy themselves.

Satire. If you have a large solar farm where all the ground was covered by 100% efficient PVs what would be the equilibrium temperature under the panels? (it wont be 0K but it will be cold)
Nah. He's right.uh oh, fight
After looking at this i now have a better insight on why the rush for storage systems is so important.For those more interested in the economics than the science:

More about hydro power than solar though. But no thread on hydro yet soThere is a new power transmission line being built from Quebec to NYC. The interesting thing to me is that it is a buried HVDC line. I did not know that HVDC lines existed and were more efficient than AC lines for long distances.

True, but HVDC lines could get solar and wind energy from where it is being produced to where it is needed with less line loss.More about hydro power than solar though. But no thread on hydro yet so
Interesting nonetheless.
Makes total sense. What else could you do with a former landfill that would benefit society.Some people complain about how there are too many landfills.
Some people complain about how solar panels use too much land.
And then you have those who install solar panels over landfills.

"There are over 10,000 closed landfills in the United States, yet only a small fraction of these parcels have been redeveloped. Transitioning more of these landfill sites into solar projects will create more local tax revenue, jobs, cleaner air, and affordable energy for residents throughout the country."
There are about 20,000 incorporated towns and cities in the US. All that trash has to go somewhere. Interestingly, there are only around 1500-3000 active landfills and 10,000 abandoned/decommissioned ones. Anything brownfield is a good use for solar if it isn't going to be redeveloped.that doesn't seem possible to have that many landfills in this country. Perfect place to totally cover with solar panels.
Should try to be funded from the existing IRA if possible.It looks like Puerto Rico is finally going to get some help from DC.

Yeah, that's going to be a lot easier to manage than getting $3B in new funding for PR through Congress in January. I suppose it could be rolled into the federal funding bill that's coming up now, but $3B is a lot to add on short notice. It can be done if there's political will, but it's harder.Should try to be funded from the existing IRA if possible.
... manage ... funding ... Congress ... federal ... bill ... political ...
Try things out is part of the fun.... I wonder how well it will work & what will the longevity will be. Time will tell.
You probably know more about this than me. I'd say it depends on where they are, and what the total cost per year is in each case.One of my clients is somewhat dissatisfied with grid reliability at their terminal(s) as their utility transitions to renewable power. Their proposed solution is kind of interesting though--they want to double down on renewables by installing a solar farm and batteries. I'm not sure if they're going to go to a full-on disconnected microgrid or if they'll stay connected to the main grid for backup. Personally, I would stay connected to the main grid, but there's sure to be many factors that I don't fully understand.

Honestly, it's a little hard to tease out. We were also talking about other stuff and I had a deadline that day so I didn't really have the time to ask more detailed questions. I'm going to be somewhat nonspecific here because identifying the location would more or less identify the client.Why is his grid getting less reliable?
Cool that the solar industry has traction, but someone is going to chime in now complaining about rules and incentives, trying to steer us away from solar tech and make this into some kind of dog pit. It's not that I want to be a bouncer, it's that I have to.California is changing the rules on home roof top solar panels so now there is an incentive available for home owners with solar to install battery backup systems to stabilize the grid.
