Further Information

I tried to connect this with your low inertia solar motor 1820rpm and it won't power it up. I used a battery and managed to power up the motor. The motor operates on 0.5-3V and this should provide 1.5V. Please help if u can.
Asked by: Youcef Belkhiter
Hi Youcef, Although you are correct that this solar cell would provide 1.5V's it is likely you aren't providing enough current for the motor. At best conditions (bright sun, with no clouds) the solar cell would produce around 400mA. This would be far less in overcast conditions.

Is it possible to connect 3 of these is series to give 3 times the voltage at the same current output (400mA)
Asked by: Will
Hi Will,

Yes that is correct, you can do that provided your components can take the voltage.

Best Regards

You said that the 1.5V 400mA is a best case scenario. Should I use 2 panels then? Is so, should I connect them in series or in parallel? I would prefer to have some movement at lower light levels.
Asked by: Douglas Grainger
Hi Douglas, You could use 2 solar cells to improve the amount of current you produce, if you put them in parallel you would keep the voltage at 1.5V but increase the current, this is likely the better option.

Hello, is one of these solar panels enough to run your geared solar motor?
Asked by: Douglas Grainger
Hi Douglas, If you are referring to this item, https://www.kitronik.co.uk/2560-solar-motor-with-gearbox.html then yes you should be able to power the motor and gearbox with this solar cell. Please be aware that the 1.5V 400mA stated would be a best case scenario, in normal conditions you would see less than this.
Answered by: Michael Lockhart

Would this 400mA solar panel replace a 1.5v AA battery powering a small motor turning a static model aircraft propeller
Asked by: Darryl
Hi Darryl, You may be able to change the batteries to the solar cell. The issue would be the current draw of the motor, 400mA would be the best case scenario for the solar cell to produce. In British summer time light you might only get half that or maybe even less. If you put a multi meter across the motor and power it using the batteries you can then find out what current it is drawing.
