6.Application
① Solar Power Plants: Used to connect solar panels to inverters, transmitting DC power generated by panels to be converted into AC power for grid connection or local use. This includes both large - scale ground - mounted power plants and small - scale rooftop solar installations.
② Building - Integrated Photovoltaic (BIPV) Systems: As an essential part of BIPV systems, where solar panels are integrated into building structures (such as roofs and facades). The cable links these panels to the building's electrical system, providing a clean energy source while enhancing the building's aesthetic.
③ Agricultural Photovoltaic Projects: In agrivoltaic setups, the cable is deployed to connect solar panels installed above farmland. It enables power generation while minimizing impact on crop growth, often requiring careful installation to avoid obstructing sunlight for plants.
④ Photovoltaic Energy Storage Systems: Connects solar panels to energy storage batteries and vice versa. This allows for storing excess electricity generated during the day for use during periods of low sunlight or high demand.
7. Features
(1) Weather Resistance: Made with materials that can withstand UV radiation, ozone, and extreme temperature changes. The outer sheath is often resistant to sunlight degradation, preventing the cable from becoming brittle or losing its insulating properties over time due to long - term sun exposure.
(2) High - Temperature Tolerance: Can operate at elevated temperatures, typically up to 125°C, which is crucial as solar panels can heat up significantly under sunlight. This ensures continuous power transmission even in hot climates or when the panels are generating high amounts of electricity.
(3) Mechanical Strength: The cable has good tensile strength and flexibility. It can endure the stress of being pulled, bent, and routed during installation, as well as withstand mechanical impacts during its service life. Some types also have enhanced resistance to abrasion, protecting against damage from contact with sharp edges or rough surfaces.
(4) Fire - Retardant and Low - Smoke Zero - Halogen (LSZH): Many photovoltaic cables are designed to be fire - retardant, reducing the risk of fire spread in case of an electrical fault. LSZH - coated cables are also common, which emit less toxic smoke and harmful halogens when burned, making them safer for use in both indoor and outdoor environments, especially in areas where human safety and environmental protection are critical.
(5) High Efficiency: The low - resistance conductors in the cable enable efficient power transfer, which maximizes the amount of electricity that can be harvested from the solar panels. This directly contributes to the overall efficiency of the solar power generation system, increasing the return on investment for solar installations.
(6) Long Service Life: With its robust construction and weather - resistant materials, photovoltaic cables are designed to last for 25 years or more. This long lifespan reduces the need for frequent cable replacements, minimizing maintenance costs and ensuring the long - term reliability of the solar power system.
