April 7, 20224 yr Hi there Can anyone provide info on solar array panel lightning protection for my system which includes 3 panels on the roof? Thanks Pat
April 8, 20224 yr Hi Pat. There is so much debate on this, but can only tell you what I did.... Daisy chain all panels together with 16mm2 wire and run down to an earth spike in the ground.
April 8, 20224 yr Mine are earthed , 3 spikes in the ground, 1m apart. Also advisable to install both type 1 and type 2 DC SPDs on the incoming PV.
April 8, 20224 yr Author Thanks for this info guys. What is the function of Type 1 and type 2 DC SPD's and how are they installed and what is the cost?
