That is interesting. Thanks for the info. This site says that overall
efficiency for residential installations varies from 13% to 18%, which is
in line

BTW - does anyone have more info on Quantum Boost than is on their website?

This could be a significant breakthrough in solar.
It is an add-on which increases the output of exiting cells by 20%. Thus 2.5
kW existing system becomes

Is this the quantum dots that absorb heat?

That QD thing is similar but probably not the same. I get the feeling that
Quantum Boost is being deliberately coy and deceptive with their disclosure
- which is why I was curious to get more information.
However, it does seem quite significant since it permits old installations
to be upgraded.
I called Ultra Solar since they're only 30 miles from me and I have a PV
system in place. The phone number on their web site goes to an anonymous
voice mail box that seems to be full. They're probably defunct.
I don't see how it could work as claimed anyway. It sits in the DC path

Alan,
It is suspicious. Glad you called.
However, as for the circuit - extrapolating from the info on their site
seems to indicate that pyroelectric pulses occur in the modules and these
are fed back to the cell for some kind of a positive feedback loop.
Perhaps a sharp HV pulse, fed

Various stats.
Article lead: Solar photovoltaic (PV) installations in the U.S. topped
4.78 GW in 2013, an increase of 41 percent over 2012, according to the

4.78 GW is the nameplate capacity.
Wind averages 20 to 30% nameplate. I wonder how well solar fares?
40% of flux Depends how fast your robowasher is. It pays to invest in one

I installed a 2.5 kw system in Feb 2003. The inverter currently shows
38,883 kwh since start-up. That averages to 9.7 kwh/day.
With an on-line time of 10 hours per day, that's 39% of nameplate
rating. Averaged over 24 hours, it's 16%.
