How can I power my device using a Solar Panel and capacitor bank?
Will this work?
You'll need more capacitors, a lot more. Another problem is you'll also need an MPPT tracker and capacitor charge controller. A bigger solar panel with a higher voltage would also be recommended. The best option would be to use a battery.
The boost converter only works to 0.9V so there is energy stored in the capacitor that cannot be used.
You'll still get \$ Q=1/2*C*V^2 \$
\$ 1/2*1F*3V^2-1/2*1F*0.9V^2=4J \$
4J/(1700mW seconds) = 2.35seconds
Which means to run this for 1 hour you'd need 30 1Farad capacitors in parallel, and it would take a long long time to charge up.
The second problem is the above calculations are only good if the capcitor actually reaches 3.3V. In the diagram above the solar panel could only charge the cap to 1.3V, which will yield even less energy storage.
The third problem is you need a solar charge controller, because a capacitor is a really high load, the solar cells won't be operating at their maximum efficiency. Because of this the capacitor may not charge at all, or take a very long time.
The diode also does not help and contributes to a lot of loss from the panel.
