6.5V * .28= 1.82 Watts, and if you are charging a battery while doing the motor, you need at least a 2 watts solar panel. Depends on what the battery you need for. If it's just for powering the motor, It's better to get super-capacitor than battery.
I am trying to use a small solar panel to charge a battery and power a small DC motor 6/9v.
I don't know what type of solar panel I need to buy in order to power a motor that is rated for 6V DC, has an operating voltage of 1.5-6.5V DC, and no load current of 280mA. It is a very small standard DC hobbyist motor.
Is it correct to say that the motor is using (280*10^-3)(6.5v) = .5096 Watts? Therefore, I need a solar panel that can produce at lease .5 Watts and 6V?
Also, what type of battery do I need to hold the charge generated by the solar panel? Is a 9V rechargeable battery sufficient?
