Wondering ... if I have metal solar panels on my metal roof, and they are properly grounded, am I good ? Is this virtually as good as the LPS talked about in this thread earlier ?

Also have tall pine trees within 30 feet of house. They are known to be 'lightning rods' due to their root system. Does that offer some protection to the house ?

Most of the transient energy is carried on the surface of the conductor so they use braided cables made up of many smaller wires to increase the surface area.

No, they are poor conductors, lightning may jump from them to your house.

Instrumented commercial high high risk sites record multiple strikes with no damage. Check out NASA for extream examples. |

Lps
We had LPS installed in early 2012. We have not had a leak and have had the system inspected twice over the last 10 years (about every 5 yrs). Both times we were told our house had been hit by lightning because of the damage to one of the rods. We had no clue this happened. Last summer the house across the street from us was struck & caused a fire, but was quickly brought under control by the VPSD. Still the damage was in the 10's of thousands of dollars. Since that time, at least 5 other neighbors had LPS installed.

I am not sure about these lightning protection systems. I worked on lightning protection systems for antenna an radar systems. The specification at first was to provide a 45 degree cone of protection to the system and later updated to a 60 degree cone of protection. The lightning rod has to be tall enough so that from the tip of the rod going out 45 degrees everything under that umbrella will be protected. They then increased it to 60 degrees. The FAA finally came out with a spec known as FAA-019B then C using multiple rods at various degrees almost looking like a porcupine. I don’t know how many times it has been updated since I retired. I just do not see how a one foot rod can provide any amount of significant protection but I could be wrong.

If you attend you will get all the facts on the topic then you can make your own decision whether you get a system or not. If you go on Youtube and search for LPS you will see lots of hard facts on the topic and that they do indeed work. |

We had our system installed primarily because our home has natural gas. This is not distributed throughout the house with, say, the black pipe that we knew up north but rather by a material far more flimsy (for lack of a better word but meaning essentially the same. And of course gas is distributed through the attic and then dropped down the walls to range, water heater, furnace, and clothes dryer. Without LPS I'd have little to no confidence in the gas piping permitted here in TV. |

Just to add, LPS systems do not attract or repel lightning. All they do is provide a safe path to ground for the discharge if you home gets hit vs the lightning running around your house destroying everthing when trying to discharge to ground. Also as far as lightning rods are concerned, Triangle and A1 will do a grounding test to measure the ground of the lightning rods they install. Make sure you ask for the report. Also the system is bonded to the utility ground And the ground rod that was installed when your house was built. So in my case i'm grounded to 5 ground rods plus the utility ground. |
