About Photovoltaic Energy StorageIf you wish to try this idea, make absolutely certain the "cold" plates of the capacitor (the moving plates) are at ground potential. Use a good, large, non-metal knob for adjustment. A 100- to 365-pF variable capacitor with a 1-kVDC breakdown voltage ( i.e ., a plate spacing of 1 mm) becomes a 270- to 985-pF unit with 7500-VDC breakdown rating.
About Photovoltaic Energy Storage0 parallelplate Q A C |V| d ε == ∆ (5.2.4) Note that C depends only on the geometric factors A and d.The capacitance C increases linearly with the area A since for a given potential difference ∆V, a bigger plate can hold more charge. On the other hand, C is inversely proportional to d, the distance of ...
