That's really interesting, Dennis. It seems a shame your idea isn't being commercialized at the moment but it seems to be benefitting you, so that's definitely a good thing.

Elizabeth M. My scheme isn't so much raising the specific efficiency as in putting more sunshine on the active area so more electricity is produced. I use flat mirrors both above and below the array of solar cells reflecting more light onto them. That gives much more electric power per dollar of cost. The several solar companies representatives I have spoken to said they were selling OK for the prices they charge and besides the manufacturers won't warranty concentrated light on their panels because they might get hot from the extra sunshine and damage the panels.  I said collect the heat and use it for direct thermal purposes. They said they were not in the heat business only electric power.  Aparently no one is going for a better higher powered system at lower cost.

I am a multiple industry expert (A "Generalist") in many diverse technologies. I combine ideas from diverse fields to create better solutions than a specialist can...

That's interesting, Dennis. Are you sure there isn't a company working on this? Do you work in the solar cell industry? If it's such an obvious solution, I am surprised no one is doing this. I've written a lot about solar panels and efficiency but haven't come across anything like this yet.

The truth is we could make the efficiency up 2 to 10 times greater by simple reflectors concentrating the sun's energy from a larger area onto a few solar panels . But, the installers and salesmen aren't smart enough . And the labor to install panels is three times the cost of the panels .   I can design panels which output twice to four times the energy but cost half as much with todays materials. But, the guloble public in their ignorance, pay thru the nose for mediocre equipment.

"You might want to check out the message boards on this story--there is a lively debate going on! I am sure you would have something interesting to add."

Thanks Elizabeth for this valid info. So far I hadn't noticed anything about it, surly I will check.
