Pat Posted April 7, 2022 Posted April 7, 2022 Hi there Can anyone provide info on solar array panel lightning protection for my system which includes 3 panels on the roof? Thanks Pat Quote
Slaki Posted April 8, 2022 Posted April 8, 2022 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. Quote
Yellow Measure Posted April 8, 2022 Posted April 8, 2022 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. Quote
Pat Posted April 8, 2022 Author Posted April 8, 2022 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? Quote
