<p>In the previous paper, author has proposed an equivalent circuit between PV module/string and the ground which consists of one resistance and multiple RC-components, and it was also described that at least two of them had higher attenuation frequency than 1Hz. In this paper, some new results obtained from further experiments and discussion are shown as follows: four RC-components which had high attenuation frequency were found, i.e. ≈50kHz, ≈103Hz, ≈102Hz, ≈101Hz, respectively. Under rain condition, on the other hand, their attenuation frequencies and resistances decreased and their capacitance increased very much. These four RC-components affect risk of electrical shock. A preliminary-stage discussion on the electrical shock, which was based on the estimates of the RC-components obtained under both no-rain and rain conditions, pointed out that the risk of electrical shock drastically increase under rain condition.</p>
