ParticipantI wouldn’t say it will always be a problem. Right now, the efficiency is in the teens and twenties. I think, when solar tech matures, we’ll get much higher efficiency numbers.
Not really. The reason why has to do with quantum physics. Each photon (quanta of light) has energy that is proportional to its frequency (hv with h being Planck’s constant and v being the frequency of that particular color of light). Sunlight has several ‘colors’ of light within it, therefore several different energies. Additionally each of these photons of different energies will yield a different voltage when converted to electricity. The last sentence is why it is not possible to go too much further in efficiencies. With a pair of wires, only one voltage can be generated. This means that photons with energies below the threshold (output voltage – barrier voltage) will be reflected or turned into heat. Photons with higher energies will convert to electricity but the energy above the conversion energy will be converted to heat.
There have been attempts to fix this with multi-layer, multi-tap solar cells, but these also have issues.
Moores law does not apply to everything.

ParticipantThe question would be…how do we determine whether or not it’s the originator’s (executive’s and employees of the origination company) personal money, or money they got from “investors”?
Doesn’t really matter. This problem is similar to the problems of all corporate governance… how do the stockholders know they are not being fleeced. Personally, I think that there needs to be changes with respect to the relationship between companies, their executives and the stockholders. What has been lost is that the common stockholders are really the owners of the company.
If the money loaned on the retained portion comes from investors, but the origination fees go to the originator (executives and employees — with little of that money going back to the actual investors), then they will again be gambling with other people’s money, and will have no incentive to process good loans.
If most of the money gets ‘redirected’.. depending upon how done, that could be fraudulent conveyance, which will destroy the corporate shield between the company and its executives.

ParticipantI would like to install solar panel but I think the technology is still in its infancy. I constantly read about new break through in solar tech. They’re talking about being able to get the cell to be so efficient and flexible that you can use it as your window
Already here.. Sun Tech Power.. Efficiency will always be a problem. The ‘window’ types will be less efficient because they are passing through light that might normally be converted.

ParticipantI want to know how much you pay for installing solar panel?
Depends, see http://www.affordable-solar.com/ as a starting point. I noticed that they don’t always list the best panels (best performance/cost ratio – measured as $ per watt) though. First Solar’s production cost is about $0.89/watt – don’t know what they charge, Sun Power’s arrays cost nearly $2.50/watt.. but their is a second difference, First Solar has about 11% efficiency of conversion while Sun Power’s is about 23%.. so fewer panels are needed and less mounting hardware, roof/surface area etc.
from which company?
again, see website above.
The energy generated from solar panel can cover your full electricity bill?
depends upon installation.. Some people go for overkill… http://www.solarwarrior.com/ This one supplies enough to recharge the guy’s electric cars and he has a battery backup with storage close to 1 week of consumption.. and still makes his house a net provider. .. though it would take almost 2 of his systems to offset Al Gore’s consumption. There is also a San Diego ‘group’ that tracks their production – http://www.livesolar.net/ – please don’t everybody jump there and crash their server.
