• Ability to fulfil utility-scale solar projects.

Understanding the Solar Cable Market in 2026

The global solar cable market is projected to more than double between 2024 and 2030—from USD 1.12 billion to USD 2.14 billion, growing at a CAGR of 11.4%. The market is growing rapidly due to the declining price of solar installations. Some of the market drivers are:

• Legislation that requires governments to reach sustainability targets

• The growing popularity of clean energy and demand for renewable energy

• Declining costs of solar installations

• A boom in solar technological advancements

• Subsidies and tax incentives for solar panels

• In recent years, solar installations have become a life-changing part of the automotive industry.

• Over two-thirds of solar cables are made of copper, with the remaining one-third being aluminium. The market share of aluminium cables is growing, as they are a cost-sensitive alternative for large utility projects.

• DC cables have 63.2 percent of the market share to AC 37 2 percent. Cables are needed in large-scale commercial solar installations.

• By end-use, utility installations are the biggest driver of the solar market.

• The North American market is the largest, but the Asia Pacific has the largest revenue share, thanks to the rise in solar energy infrastructure in these regions. This includes India and China, the latter being the largest producer and consumer of solar panels.

• The THHN wire segment is expected to reach over 1.9 billion USD by 2034, making it the most popular type of cable in solar installations.

Customers are primarily seeking high-performing cables, with price also being a key factor in this highly competitive market.
