I find some people connect a super capacitor like (16v 88F capacitor bank) in parallel with the 12v 100Ah solar battery to optimize the surge current draws from the battery due to running heavy inductive load by the inverter (to increasing the battery lifespan).
Now enter the ultra capacitor bank. It can't be directly paralleled with the batteries. If you pulled a very high current surge, it would pull the capacitor voltage down a bit as that is the only way a capacitor gives out energy.
This relationship shows us that when we connect capacitors in parallel then the equivalent capacitance of the circuit becomes sum of the capacitances of each individual capacitor in the connection. in other words, the total capacitance of the circuit increases.
This article will examine how to use supercapacitors with small solar cells in two case studies: Relatively low power applications which only operate when there is indoor light, providing sub mW power and transmitting with BLE. The supercapacitor need only be sized for the energy and power to support the peak load burst.
The supercapacitor need only be sized for the energy and power to support the peak load burst. An outdoor solar cell for higher power applications which must run when there is no light, such as overnight and reports by SMS using GPRS. In this case the supercapacitor is sized for energy storage over the dark period as well as for the peak load.
It is however very inefficient use of the Supercaps when you simply parallel them with a battery. Consider that a 12V battery may have a fully charged state of 13.4V and a fully discharged state 10.5V. Putting a large supercap in parallel with the battery does not change the terminal characteristics.
5.07 Parallel Connection of Capacitors
Let''s start, first, with the parallel connection of the capacitors. In this case, capacitors are connected to one another such that the potential difference across each capacitor within the combination or connection becomes equal to the other one. So capacitors are connected in parallel if the same potential difference is applied to each ...

Charging Caps with solar
Also IF you are going to buy super capacitors, then please note that most of them are rated at only 2.7V. So you would need to put two of those in series, creating a 5.4V capacitor with half the original capacitance. And you would need to connect all your solar cells in parallel to not over voltage the capacitors. Also make sure the capacitors ...

Charging supercapacitors with small solar cells
The simplest solar-powered circuit to charge a supercapacitor is made by just connecting the capacitor to the solar panels. The only other important component is a diode to stop the supercapacitor from discharging back into the solar panels. The diode should have a low forward voltage drop like a Schottky diode.
