  • Capacitor Discharging- Explained

    C affects the discharging process in that the greater the capacitance, the more charge a capacitor can hold, thus, the longer it takes to discharge, which leads to a greater voltage, VC. Conversely, a smaller capacitance value leads to a quicker discharge, since the capacitor cant hold as much charge, and thus, the lower V C at the end.

    In these systems, you are paying something on the order of $10 to $20 per watt (once you add up the cost of the solar cells, the batteries to store the power, the power regulators and inverter, etc.). Fifty watts at $20 per watt means that you have to spend an additional $1,000 just to power the transformers.
