Placed in series, you do indeed add to the voltage. But when in paralell, you keep the same voltage but your current is increased.
And when you convert from low voltage to high voltage, and also run through a bridge rectifier to convert it to AC the current is likewise reduced.
from what I have read, sunlight contains about 1 KWH per square meter. I'm sure our current solar panels aren't efficient enough to utilize all this energy though. Much of it is simply converted to heat which is disipated. But even with solar cells that are 100% efficient, 1KWH is all you can get out of 1 sq meter of surface area.
Until someone can prove me wrong, I believe cold fusion is a myth....like perpetual motion or
that car that I keep hearing people claim is locked away in their neighbors garage that gets 400 mpg and runs either on water or vegetable oil.
Proof is in the pudding and to me, Newtons laws are still rock solid.
