Hi Robert,

I remember just a few weeks ago reading about a company that is tooling up
to start producing  wafers that will reduce the cost of PV panels to 20% of
the cost of todays panels. Apparently they have found a process that allows
for a much lower manufacturing cost of the wafer. I'll have to see if I can
find this article again. I think they said it is still a few years out
before these panels get to the consumers due to testing and so forth. And
one concern of theirs was will the final distributor past the cost savings
to the customers.

Is a 48v ET doable? It would make things much simpler.
I could yank out that dratted charger and squeeze 4
batteries in that area. E12
Obviously it wouldn't void the warrenty but would it
fry the components with 33% more voltage. (visions of
Tim "tooltime" breaking stuff)
I am setting up Photovoltaics to do my charging
(shortage of big wattage PV in the US, Germany, soon
Italy and Spain are greening their countries with
federal subsidies so our prices are up)
24 and 48 volts seem a lot easier to get components
for
