Trying to help my neighbor with his Grid-Tie rooftop solar installation in California. The 9.75 kW system consists of 26 panels split into five arrays. The distance between arrays varies between 5ft - 20 ft. The roof has many ridges, hips and valleys to contend with. The panels will be wired into two DC strings with a 12 panel string comprised of one array and a 14 panel string comprised of the remaining 4 arrays. Using Solaredge inverter and optimizers. Questions: 1) Is conduit required between the arrays? 2) if yes, can flexible conduit be used due to the many roof ups and downs between arrays. 3) Conduit diameter? Assume only two DC 600V cables and ground needed in a possible conduit. 4) Assume a conduit support/riser is needed every 10ft. 5) Other thoughts or links to array wiring would be appreciated?
Thanks,
Don
