which wire is best for solar panels

When choosing wire for solar panels, the best option depends on durability, efficiency, and environmental conditions. Copper wire is the most common choice because it conducts electricity well and resists corrosion. It’s also flexible, making installation easier, especially for rooftop systems. However, copper can be expensive and may require thicker gauges for longer runs to minimize energy loss.

For a more cost-effective solution, aluminum wire is an alternative, though it’s less conductive and prone to oxidation. It’s lighter and often used in large-scale installations where weight matters. Always check local electrical codes, as some areas restrict aluminum for residential use. The right wire ensures safety, performance, and longevity for your solar setup.
