100% efficient is 1000 watts/m2

1/m2 = 1550/in2

So you have 8 x 8 = 64/in2

64/1550 = .041/m2

So at 100% efficiency a panel could generate .041 x 1000 watts = 41 watts

You are claiming 96 watts which is 234% efficient. If you buy that, then I have a book I can sell you that instructions you how to build a HHO generator for your car using nothing more than simple items in your kitchen that will make your car get 100 MPG. All it will cost you is $99 plus shipping.

thanks for your reply,,,,

but is there a on-line calculator that can figure this out with different values and sizes... that would be really handy....

**superben** · 06-11-2010, 01:43 PM

lets try again with a little bit more information

.. lets try again with a little bit more information....

the cells being used are ....
Polycrystalline Solar cell that measures .42 volt, 2 amps, 1 watt
{for this panel we will use 4 of them}

now if you hook them up in series...
you have around 1.68 volts, 2 amps ,and 3.36 watts

and in parallel you have .42 volts , 8 amps and 3.36 watts

if this is correct ,,, further discussion will be necessary
if you think out side the box... the first post of this thread is possible

I can charge 12 volt batteries with 8 amps from 4 "solar cells" wired in parallel

does any one know how I did it?

so, you have
4 solar panels or
4 solar cells ?
Panel consist of cells.

surely I cant be the only one who has figured this out

what if you had a
solar panel that was
8 inches by 8 inches....
and it could produce
12 volts and 8 amps...

Here, 1st post, you said "panel".

**superben** · 06-16-2010, 01:54 PM

4 cells... wired in parallel .... 12 volts... 8 amps...

just do some messing around and you can make a circuit to boost the voltage
so then you can have the amps and the volts ...

then all of a sudden solar cells can do more than "trickle charge " batteries

[insert popcorn eating smiley to signify that I am somehow enjoying this thread]

Are you sure that the battery wasn't charged to begin with?

**superben** · 06-17-2010, 01:01 AM

I am sure...

solar panels suck so bad there is much room for improvment...

I'd like to see a photo of your meters, displaying the magical solar panel you have. 96w from a 8"x8" panel with un-concentrated sunlight ?

They have come a long way with solar the past few years. I'm kind of impressed with the solar panels. What I think stinks is the amount of batteries you need to do anything that pertains to heat.

Good luck with your project. The I'm willing to believe the holy grail of solar is still out there someplace.

good luck to you as well good sir....

try wiring your cells in parallel to give you maximum amperage...
then use a circuit of sorts to raise the voltage....

just like how a stun gun works... it takes 9V and raises it to hundreds of thousands volts..{ but no amps}

but in this case you only have .42 volts and only need 14V to charge yo ****
your panel makes the amps and the circuit makes the volts

But the WATTS have to remain the same. DC-Dc converters are everywhere, computer motherboards, stun guns, and TV's. But you trade amps for volts (exactly like your stun gun) A 15W panel, can still only generate 15 watts.
