Could you use this to charge a small battery?

Asked by: jeeneus
This will charge a small battery. As long as the voltage rating is under 2 volts this can provide a charge for it.

Can you please provide the dimensions of this and all your solar cells? Thanks.
Asked by: Nicolas Name
This panel will measure 66mm x 95mm x 6mm (2.6" x 3.74" x 0.25"). The 1V counterpart to this product is the same size. Our larger panels (chargers) have their dimensions listed under "Product Details" on their individual product pages.

how many would be needed for a 10volt 2amp supply

Im thinking of using these for a stereo.
Asked by: William 67
now this one is interesting for me, as my current audio project has shifted into an ultra efficient horn loaded 2-way di-pole line sound stage in mono...and i have also much RE experience, and am considering examining the power supply on my NU3000 to see if i can find a DC inroad...anyway...my answer may quickly send you looking elsewhere due to costs, vs. a single larger panel...but really it depends on frequency of usage, and draw....you would want storage, or a battery, with a nominal voltage in excess of your 10 volt required output...if your supply has regulation, preferably switch mode, measure the DC voltage post rectification and pre regulation...this will give you a good ball park for your storage nominal voltage....then it's a simple matter of calculating your series string to storage peak, ( up above nominal ), and inclusive of the voltage drop across your Schottky Diode, ( very important component necessary to keep the batteries from discharging through the panel off peak)....once you have the number of units in your series string calculated, it is a simple matter of adding more strings in parallel to mach your usage...do consider that the rating is peak in full sun....so you will simply get a bell shaped "power bubble" of approximately 2 hours mean width at this magnitude..Amps x Volts =Watts..best,rulg

Is there a way to rewire the individual cells to increase the voltage and decrease the current?

I was wondering if this is a completely solid model, or is there a front plate that is removable that would allow access to the cells themselves to allow de-soldering of the cells to rewire them to make them a higher voltage with less amperage, (about 4 volts at 100 ma).
Asked by: Chris94
This product is enclosed unto itself, not designed to be opened and manipulated as far as the cells within the unit. The reference to wiring series or parallel would be in relation to multiple units, I'm afraid.
