How can a solar cell be struck by lightning?
Generally new residential buildings around the roof will have a band of lightning, which can basically guarantee that the building will not be struck by lightning. To really want to lightning, then in the vicinity of the board vertical iron needle, height of 2~3 meters, enough to protect all the scope of the whole plate, welded with steel bars to connect to the roof of the lightning belt.
But the lightning rod must be reliable grounding, grounding resistance should be less than 10 ohm, if it is to build their own houses, generally do not have a grounding, lightning grounding usually adopts 3 grounding, word order or triangular arrangement, a distance of 5 meters above, the need to spend thousands of dollars, if the building ground is can be directly used flat iron or steel cited in the past so near, estimated to spend hundreds of dollars is enough
In fact, lightning arrester lightning principle is mine, the lightning current into the earth, so that there is no protection equipment lightning flow.The lightning rod is set more than the equipment you want to protect. You only need to know that the height of the lightning rod must exceed a certain height. As you have, the 2~3 meter is enough. The closer the electric plate is, the better the effect is.
