6.1.2: Capacitance and Capacitors
In contrast, when capacitors are placed in series, it is as if the plate distance has increased, thus decreasing capacitance. Therefore capacitors in series behave like resistors in parallel. Their value is found via the reciprocal of summed reciprocals or the product-sum rule.

Capacitors in Series and Parallel | Physics
In series connections of capacitors, the sum is less than the parts. In fact, it is less than any individual. Note that it is sometimes possible, and more convenient, to solve an equation like the above by finding the least common denominator, which in this case (showing only whole-number calculations) is 40.

Important in role of capacitors in distribution systems
I''m thinking utility size and grade capacitors can be used in charging and creating an inverter for solar charged batteries. Li batteries are 2v and are best charged in parallel. Li batteries are best used in series to deliver high voltage (e.g. 400VDC…200 batteries in series).

Figure 1 A transmission line with series-capacitor-compensation applied. Due to the effect of series capacitor the receiving end voltage will be instead of VR as seen from the phasor diagram (Figure 2). Thus with series capacitor in the circuit the voltage drop in the line is reduced and receiving end voltage on full load is improved.

8.3: Capacitors in Series and in Parallel
Capacitors can be arranged in two simple and common types of connections, known as series and parallel, for which we can easily calculate the total capacitance. These two basic combinations, series and parallel, can also be used as part of more complex connections.
power supply
The larger the capacitor the less ripple and the more constant the DC. When large current peaks are drawn the capacitor supplied surge energy helps the regulator not sag in output. The white and black bars on the capacitor symbol show that it is a "polar " capacitor - it only works with + and - on the selected ends.
