Question:

I have to charge a lithium 3v RCR123A in winter sunlight. How many of these cells would need to be connected together to achieve this? Also, would a diode be necessary? BW.

    Hi John, After having a look into these batteries it is stressed that the original charger should be used to charge the batteries and you shouldn’t create/use a different charge. As such we aren’t able to provide any further recommendations other than this. Sorry.

Question:

Hi Do you have a graph of output current versus light level. I need to charge a 3V Lithium Ion Cell of 250mAh capacity with the light levels of a typical English winters day of 7 hours daylight. Can it be done? (250/7 = 35mA/hour.) Regards

    Hi Pete, We have looked into this via a datasheet and testing this ourselves and unfortunately during winter sun you wouldn’t be able to get the solar cell to output enough current to charge this battery. During direct sun it would be able to, but shaded or indirect sun light wouldn’t be able to produce enough voltage or current.

Question:

Could this be used (with a diode) to recharge a 9v rechargeable battery in your mono amp circuit? Thanks

    You could in theory use a solar cell to charge a battery. To charge a 9V battery you would want to us 2 5V solar cells, https://www.kitronik.co.uk/3608-50v-130ma-polycrystalline-solar-cell.html connected in series along with your diode. This will drop the voltage from 10V’s to around 9.3V’s, and depending on the capacity of the battery would depend on the length of time it would take to charge.

Question:

Hi I have a dummy house alarm box on my shed, a solar panel charges 2 x 1.5 batteries to get 2 LED's to flash through the night, it works well but in the winter doesn't get enough light to flash the lights all the time, I was thinking of upgrading the solar panels and I could actually squeeze 2 of these (3.0V 100mA Polycrystalline Solar Cell) onto the alarm, this would be much larger than the one fitted, so if your still awake my question is would they need wiring in series or parallel? and should doubling up help create more charge for the battery? Thanks

Question:

Given a good sunny day in southern England in the Summer, what mA could I expect to get from the 3.0V 100mA solar cell. I'm designing a small solar powered model aircraft/glider, using a kitronik 3v motor. regards

    The maximum that can be outputted is 100mA, however this requires direct and constant sunlight. You will likely measure less than this depending on the intensity of the sun.
