High Temperature of Photovoltaic Cable Trays
Death Valley in the Mojave Desert holds the official record for the hottest place on Earth at 134°F. Low-carbon steel easily outperforms both fiberglass and aluminum in extremely hot environments. Solar photovoltaic (PV) plants in hot climates—such as deserts or tropical regions—experience extreme ambient and operating temperatures that stress DC cables. Cables exposed on rooftops or ground mounts can reach surface temperatures exceeding 80-90°C, impacting current-carrying capacity. Polyester and Vinyl Ester cable trays are non-metallic, or in a very simple sense, plastic. Here's a focused overview on the behavior, challenges, and considerations for solar cables operating under high temperatures in PV plants: Prolonged.
