Then don't install cheap ones.
You're way off on degradation of typical panels.
They are warranteed to produce 80% of the spec after 20 years, and although the warrantee is prorated and not very valuable, they do actually achieve this typically or they would have to eat a lot of panels, which just doesn't happen much.
The technology has been in the field for 30 years. Where are you getting your data?
This will not tell you if a wall is straight!
It may tell you if a corner is square.
The terms you are looking for are level, plumb, or square.
You can tell if a wall is straight with a string, a laser, a straightedge, a rangefinder and a computer etc etc, or your eye.
Or you could use math if you sampled enough points.
No the answer was "your statement is incorrect".
Regarding standards of living, our energy costs are increasing anyway. Shall we just ignore this, or respond with incorrect statements about how solar power will never work? Or both?
The amount of energy needed is available for some kind of industrial society. It would be a simple matter, technically, to reduce heat and electricity needs dramatically for residential and most commercial sites even in our society, and solar could provide a good portion of what is then needed. In other words efficiency plus solar could reduce electric and heat needs 75% with current technology and of course higher prices. Advances in storage would be required to handle the rest I think.
Reminds me of the Indiana Jones scene...
bad guy: phone cams suck blah blah good lenses expensive blah blah compromise blah blah...
Indiana: clicks photo. walks off.
mmm hmm. We don't need to produce anything as long as we are progressive and sensitive enough. As long as we have plenty of government services and public transportation we'll be fine.
I think what makes it interesting is the controllability. There is a much better chance this could scale than something which is just a new chemistry or a more convoluted surface. Once you have the ability to control the physical battery to a microscopic degree, then you are free to scale and address problems like overheating with logic, in theory. The chemistry of this particular prototype may turn out to be less interesting with advances in nanotech, like

Thanks for posting that. Stuff like that is why I studied embryology, biomechanics, and evolution.
Unfortunately, this statement: "While there may be circumstantial evidence to support either a continuous or discontinuous model of life, it is vitally important to recognize how one's starting assumptions affect one's conclusions." is, in my opinion, typical of those made by people who have not studied biology but somehow can't come to grips with their beliefs being, um, wrong. There is no circumstantial evidence, or any other kind, for the discontinuous model. Sorry. I admit I cannot draw you a picture of the stages in the evolution of flagella, but the more you study a variety of cellular phenomena you realize that there is only one possibility that is remotely self-consistent. Natural selection and evolution.
Reporting needs to be easier, imo. That does not imply it would be an automatic removal or that you could press the button without consequences for abuse.
All I know is you can watch people being scammed in real time, as a casual observer. That doesn't say much for ebay.
Also, the situation I witnessed could be prevented by a flag for tons of simultaneous listings by a user who had accumulated feedback by buying many inexpensive items and was a member for a very short time. Something they should be able to program on their lunch hour. My feeling is it's not a priority for them.
As little as possible! I saw a huge batch of blatently fraudulaent listings the other day, and I found reporting it extremely cumbersome.
Why is there not a "suspicious listing" button?
Sad.
right-click a link, select "prefetch" and it loads in another tab or window, WITHOUT closing the current window. then when you finish reading the page, the next page is waiting. That would be very helpful to me.
It's easy to knock it, but you of all people should be aware that with a nice sized solar system, there are times when you have surplus energy. At these times efficiency is not so important if the power can be used. Sure grid connecting is great but some of us have no desire to pay for the lines and service charges, and it's not really a long term solution until we solve the storage problem. I think flow batteries are interesting but they surely have drawbacks as well.
So I think it's cool as an experiment no more and no less.
"In summary, I would say that scientists and engineers already have a reasonably good handle on atoms and that the real R&D opportunities are in getting better with bits."
The first part of that statement is silly, but you're right that making money is easier by tweaking (and marketing) processes that already exist, than by creating new processes.
Now he's getting a tattoo
He's gettin' ink done
He asked for a '13', but they drew a '31'
Friends say he's trying too hard
And he's not quite hip
But in his own mind
He's he's the dopest trip
Give it to me baby
uh hu, uh hu
Give it to me baby

uno, dos, tres, quatro, cinco, cinco, seis
um, they really don't need test guinea pigs. An ammeter works quite well.
hmm that came out sounding kind of odd.
hey anyone that will give you solar products, fine.
anyways, people seem determined to make solar more difficult than it need be. It's like some kind of curse - must - not - do - it - the - easy - way. Use proven products. Buy from someone who knows what they are talking about. Think. Would you use a graphics card if you knew nothing about it but someone gave it to you? For a system your livlihood, and possibly your life, depended on?
You can judge this advice by the spelling frankly. The only correct point in his post is re: electric heaters.
Basically, the computer is the least of your worries. water pressure, refrigeration, and heat are where it gets interesting. Find a solar person who knows what they are doing. Be happy.
Generally, crt is out. laptop a lot better than desktop. Yes your budget is a factor.
Oh yeah, in my experience satellite internet works great.
BP is not the largest seller of solar panels, That is Sharp. BP is #2, close to Kyocera. BP is however the largest *user* of solar panels with their gas station canopies etc.
It's not easy to compare, but as the IEEE article states, conventional power plants can be built for 40 cents per watt. So if you can buy solar cells for 20 cents a watt that would be significant. You do have to add a lot of infrastructure, but you get the idea.
Coleman 4000 Watt generator is $400. 10 cents a watt but it sure won't last 20 years. Plus fuel costs. So really a competitive price for a solar power station would be about $1 a watt complete, which would be possible with cells at 20 cents per watt.
The article is worded poorly because the 20 year life is not really relevant in comparing cost per watt. But you can use the 20 year life to calculate an expected cost per kWh.
btw most power plants use coal or natural gas, not oil.

At this stage of exploration, wouldn't it make more sense to make a bunch of non-mobile, lightweight probes and pepper the planet's surface with them?
"There are also alternative explanations for fossil ordering which make much more empirical sense than gradual deposition" Name one.
